Can I attach a USB mic to any Android phone?
Can I attach a USB mic to any Android phone?  Which one?
I am asking since I need to be able to shoot video with sound clear of noise.
Hence, I need the phone to shoot good video quality as well(full HD at least).

Never tried with an USB mike – but using one via the "headset plug" should do, as that's what headsets use as well.

You mean the 3.5mm audio jack, right?

Exactly. I just had a black-out concerning the term, sorry.

Np, it was clear but I needed to be 100% sure:)

I've summed it up with additional details in my answer below, for your convenience :)

Android currently doesn't support USB Audio Paths. You can use USB Audio if you have a Nexus 5 with Android L Preview. Otherwise you are out of luck.

Yes, Android supports standard USB audio class devices:

Android 5.0 (API level 21) and above supports a subset of USB audio
  class 1 (UAC1) features:

The Android device must act as host
The audio format must be PCM (interface type I)
The bit depth must be 16-bits, 24-bits, or 32-bits where 24 bits of useful audio data are left-justified within the most significant
  bits of the 32-bit word
The sample rate must be either 48, 44.1, 32, 24, 22.05, 16, 12, 11.025, or 8 kHz
  The channel count must be 1 (mono) or 2 (stereo)

Also, Android 3.1 or higher can support USB audio if you buy an app from eXtream Software, which bundles its own drivers.
Also, your hardware has to support USB Host mode (USB On-The-Go).  There are apps to test whether it does:
How can I determine if my device has USB Host Mode (OTG) support?

I tested this and it works (Samsung S6, Yeti Blue USB Mic)

If you need an external microphone, and your device does not support USB audio (as Hiemanshu's answer suggests): A work-around would be using a microphone with the 3.5" audio jack. As headsets use that successfully, it should work.
I've never tried, so theoretically a side-effect could be sound output gets blocked whith the device assuming you've got a headset plugged in. If that's the case, there are apps available to control where which audio is routed to. You can find some in this list.

Android App - Same phone - Different versions on App Store
I'm using an Android application called 'Out of Milk'. I have it installed on two identical phones (hardware and software). However on one phone it is version 4.2.2 and on the other phone it is version 4.1.7.
Looking at the Google Play app store on both these phones, they each say there are no updates available. Looking at the info page of the application in the app store show that latest version is 4.2.2 on one phone and 4.1.7 on the other. Both phones are running the free version only - the unlocker (pro) app is not installed.
How can I make both versions identical?
[Android version is 4.1.2 on both.]

you can use ADB to pull the APK off one phone to install on another.

@JaredBurrows Only for rooted users though.  He can, however, use adb backup feature to retrieve the app and adb restore it on the other phone.

App developers have the ability to do a staged roll-out of updates to their apps through Google Play Store.  This means that a small percentage of users (chosen randomly) receives the update first.  The developer can gauge the feedback, and then proceed to a wide roll-out until they reach 100% of their install base.
It's possible that the latest version of this particular app was recently released in such a staged roll-out. One of your phones was randomly selected to be in the initial stage, while the other was not.  There is nothing for you to do, other than wait for the roll-out to complete.
As comments suggest, you can also attempt to sync the app manually by retrieving it from one phone and installing it on the other.  This requires installation of USB drivers for your phone on your computer, and a copy of Android SDK.  If you are rooted, you can get the APK of the app using adb pull /data/app/<app_package_name>.apk c:\ command, and then connect the other phone and do adb install -r c:\<app_package_name>.apk.
On unrooted devices you may want to look into adb backup utility which allows you to generate an .ab file which contains the APK of the app, along with its data.  For example, the command adb backup -f c:\Skype.ab -apk com.skype.raider creates "Skype.ab" file on my C: drive that contains the Skype app and its data.  I can then use adb restore c:\Skype.ab command to restore the app with the data. Optionally, you can clear the data for the app from your other phone in Settings -> Apps.
The difficulty is locating the package name of the app you want to back up.  Although package names are usually descriptive enough, sometimes they can be quite cryptic.  Fortunately, Play Store itself has the package name in the URL.  In your example, the app Out of Milk is located at the following URL: https://play.google.com/store/apps/details?id=com.capigami.outofmilk. The portion of this URL after "id=" is the package name. In this case it's com.capigami.outofmilk. So your backup command becomes adb backup -f c:\OutOfMilk.ab -apk com.capigami.outofmilk.

What microphone can I attach via the 3.5mm audio jack @ Samsung Galaxy S4?
I need to attach an external microphone to my phone.
Can I do this via the 3.5mm jack on my Samsung Galaxy S4? What kind of microphone would it be?

I found this 3.5mm jack noise-reducing microphone on YouTube: Galaxy Samsung S4 External Mic for mobile phone and here is the mic quoted on eBay. I plan to test it and return some feedback here. I hope it will serve me well enough for the footage I need to create - some homemade lectures.

You can do that, but you'll need an adapter: the 3.5 mm jack on the phone is for a headset (with earphones and a mic), so it's not made to take a standard mic input. You need to find an adapter that's for plugging a microphone into Samsung phones. It might be tricky to find, but they're inexpensive.
Once you have the adapter, any microphone with a 3.5 mm connector will do. Stage mics requiring XLR and 12 V "phantom power" won't work: you'd need an extra device to supply power to the mic, such as a mixing desk with a 3.5 mm output.

I don't need a stage mic, but any mic that can clear noise very well. I prefer it to be standalone, is this possible?

As I say, any mic with a 3.5 mm connector will do. I can't recommend a particular one to you: that's way outside the scope of the site.

Anyone help me, how to root this device.

What firmware are you running? MDL, MK2, MF3? Please add the build number to your question.

Keeping this question open, as the answer is valid.

The file you downloaded "CF-Auto-Root-jflte-jfltexx-gti9505.tar.md5" is not designed for the device you are trying to use it on.  GT-I9505 is the international model, and is different from your AT&T model SGH-I337.  Any rooting methods must be tailored for your exact device model.
I recommend heading to the section dedicated to your specific device on XDA-Developers forums and reading up on guides and how-to's.  Specifically, this post lists several rooting methods, depending on your phone's currently installed firmware/baseband version.

Can Microsoft Exchange Activesync in Knox container still wipe my device
I set up my work email account (which uses Microsoft Exchange Activesync) on my personal     galaxy s4 (gt-I9505 running 4.4.2) under the Knox container (version 2.0). If the Admin tries to remote wipe my device will it
  a: do nothing
  b: wipe the Knox container
  c: wipe my entire phone

I've looked around for answers on the web and gotten a few guesses but I would like some proof or at least hear from someone with first hand knowledge.
-Thanks

I finally sent an email to Knox user support:

I have a galaxy Note 4 with MyKnox installed. I have setup an
  activesync ms exchange account in the email app. One of the
  permissions is to allow remote wipe. I know that I have the ability
  through the MyKnox web portal to remotely wipe my own device. what I
  want to know is if the MS exchange admin sends a remote wipe command
  (through exchange, NOT throught the MyKnox portal) will it just wipe
  the container or the whole device?

Here is the reply:

Our R&D team has updated that remote wipe command through exchange
  will only wipe the container if the Exchange account is setup inside
  the container.
Please let us know if any further queries with respect to this issue
Best regards, Tanuj K Samsung KNOX support

My own addition:
This may only apply to MyKnox and not the other versions. I have friends who work in IT for organizations that use the corporate version and have been told that they can add additional permissions and privileges extending outside the Knox container.

The Knox container will be wiped.
Knox is a sandboxed instance of Android with its own separate security policy. Exchange's device administrator has no access to the contents of your phone outside of Knox and cannot wipe your personal data.

That's what I thought and hope for. Do you have any documentation to support your statement or at least personal experience?

You didn't mention what version of KNOX you have or what MDM your company is using.
With My KNOX, a personal version, you can wipe the entire device:

https://www.samsungknox.com/en/products/my-knox
https://www.samsungknox.com/en/system/files/admin-doc/Samsung_My_KNOX_Visual_Walkthrough_Guide_14.pdf

With KNOX Premium, an enterprise version, it depends upon the MDM.  Most MDMs can wipe your entire device:

http://www.tomsitpro.com/articles/enterprise-mdm-vendors,2-732.html

Samsung's MDM can be configured to wipe the device or just the container:

http://www.samsung.com/my/business/mobile/platform/mobile-platform/knox/pdf/MP_Samsung_KNOX2.0_Technical_Whitepaper_V1.0_20140310.pdf
https://www.gov.uk/government/publications/end-user-devices-security-guidance-samsung-devices-with-knox/end-user-devices-security-guidance-samsung-devices-with-knox

The real answer is:  Go ask your IT department.  Find out who set up the MDM and ask them.

Knox came pre-installed on my device. The Company IT dept had nothing to do with my setup and doesn't even know I am using it. I am using the mail app inside the knox container to connect to the exchange server. I could have done the exact same thing outside of the knox container. This is not the corporate version.

It sounds like you have My KNOX installed, and thus you are your own admin.  You can set it up at the "My KNOX User Portal" at my.samsungknox.com, and then you can wipe your own device if need be.  Good luck.

I don't understand which good content did I really remove in this suggested edit. Your answer has too many obsolete links, and the sources are scattered and not wrapped under text which looks bad. Are you saying that obsolete links are good content for you? Goodness.

I would say that you don't have My Knox because if you look at My Knox videos you will see the icon says My Knox.  However, the version you are talking about just says Knox.  I can not find the version support for it either (as I have the same version you do) even though it says Knox 2.3 in the about tab under my apps -> Knox Settings -> Knox version.
Now if you go to the Knox settings -> Device administrators, you will see exchange sync or email services with the ability to erase data.  The question is when I go to device manager for the personal side of the phone the exchange service (email service does not have permission to erase all data).  I am confused myself. I would suggest that you use an old phone that can use Knox (or not) and use it with wifi only and use the email server only when wifi is available. If they do wipe the phone none of your stuff is on it.  I will carry two phones untill I figure that out.
Centrify is the developer (Youtube link) and so is the Samsung team.   Let me know what you come up with.  I have missed my password the amount of times required(20 I believe) and it resets the Knox version to new.  There is also this site for support. Email them as I am now.

What is the purpose of the cache?
I am using a phone with limited internal memory, and I noticed that my app cache has swelled up to 130 MB. What are the pros and cons of deleting the cache for certain apps? I don't understand what the cache is used for in the first place. Could someone explain?

What exactly do you mean by "the app cache"? There are lots of caches in Android and Android apps, so you'll get a better answer if you can be more specific. Just describe where you saw this 130 MB figure if you're not sure.

The 130MB figure comes from the folder named "Cached Data" under the internal memory. I was assuming that this is the sum total of all the caches of all the apps, but I might be wrong.

Cache:-Its a temporary storage file used by websites as well as the applications to store some data on your device.
Cache memory contains references(where to store the settings i.e. in which folder it should load or store the source file ), thumbnails(images to be displayed in the application) etc.
Advantages of Cache:-
1.Once you have already loaded the application then your application loads exceptionally fast when compared to the first time load.(Apps like browser will load your websites much faster as they are stored in your cache)
2.Instead of the application loading the wallpaper from the source(Phone memory) every time you load the application it will create a buffer memory from which it can directly load the wallpaper saving the processor of the phone from doing this task.
Disadvantages:-
1.The website takes some time to load the requested page as there's no buffer memory. This is not much big disadvantage as for the second time the page will load fast.
2.Although your pages are loading fast or the application is responding faster there is limited storage space which the Cache memory can store. Once it get's filled / is nearing to then other application/same application will get slow as there's no space for the application to operate.

On my GS3 I looked under running apps and selected show cashed processes
On clicking on one of them it gives the following description
Old application process kept for better speed in case it is needed again

I can only assume from this that cache is storing certain data when an app is first ran, so by deleting the data the app will run from new each time

Facebook app nagging about syncing. Can it be disabled?
While only a minor issue, it is annoying. I've had a look at the settings for the facebook app, but even after disabling anything that did seem relevant to this message popping up, it still keeps showing. The app was not pre-installed on the phone, it was added by my own will, if that is any relevant information.
Is there any way to disable this, or is it a cruel "feature" added to the facebook app that can not be disabled?

Are you sure this is coming from the Facebook app? You can check by long-tapping the notification to bring up a menu, then App info on that menu.

Ouh... Hard to say, I tend to simply dismiss the message, and it's kinda random when it pops up, so, can't try that right now. Tho, I am quite sure it started when I did install the Facebook app. I'll see if it pops up again during the day, and I'll check.

By request from 'Dan Hulme' who replied to my question, I got the message to pop up again and managed to get the app-info. It turns out to be an app connected to the Facebook app called 'SNS'. I simply removed the tick from the "Show notifications" option. The message no longer pops up.
It can otherwise be found on "Settings -> More -> Application manager" Shuffle so you see the "All" list, then scroll down til you find the SNS application.

In case you're wondering what that SNS is, it stands for Social Network Service. Usually it's the preinstalled syncs or widgets that use this.

Galaxy Ace 2 won't display images due to lack of memory?
I have a Samsung Galaxcy Ace 2, and it doesn't display images due to lack of memory, as it says. When I open the gallery app, it says "There is not enough space (__ mb) in your device memory. Delete some files." Whenever I do so, it's still not enough. I have this problem a lot, and I delete most of my unnecessary files, and it remains unchanged, usually, and rarely actually displays my remaining images.
My device memory is 1 GB, and I have an 8 GB memory card, and most, if not all my things are on the memory card. Can anyone help me with this? I have no clue anymore, and alternative solutions just don't seem effective to me at all.

Please take a look at some of the questions under the [tag:insufficient-memory] tag that I just added. Many users have had this problem, and there are several things you can try to clean up internal storage.

You're out of RAM I think. Clean the RAM memory in Task Manager. Use any other apps like advanced cleaners which you can easily find in Play Store to remove other Junk files.
Post what happened.

How to sync my iCloud email acct using the stock email app?
I am using cyanogenmod11 on both my phone and tablet which comes with AOSP email app. I've also tried the latest stock email app that Google released recently on the playstore.
No matter what I do, I can't get my email. The server settings (both imap and smtp) validates fine but nothing happens.
I've looked at various guides available in the net. They are very much the same. The settings used are the same.
I have tried K-9 mail app using the same settings and that works fine retrieving my data. So I believe I'm using the correct settings.
Any ideas what I could set in the stock email app?
Thanks :)

Have you tried the cloud magic email app yet? https://play.google.com/store/apps/details?id=com.cloudmagic.mail

if I were to use a third party app, I would use K-9 as I know that works. I'm asking on how to make it work on Google's email app. thanks :)

This should solve your problem http://www.androidcentral.com/how-set-your-icloud-email-account-android http://support.apple.com/kb/HT4864

that's one of the guides that I used. Works for K-9. but not for the stock email app (both AOSP and the one from the playstore). And I've also seen the Apple link. The guides I've seen like the one from Android Central uses SSL/TLS for smtp but it never worked for me. But following the Apple suggestion of using STARTTLS works. As I said, both email and K-9 validates my server settings fine. Except only K-9 retrieves my data.

How to import Yahoo Mail contacts into Google?
I need help with importing my Yahoo Mail email addresses to my Gmail contacts list, using a Samsung Galaxy S4. Whenever I try to email anyone from my Gmail contacts list, I can't because they aren't imported from my Yahoo Mail account.

Use the second method suggested by Chank. Exporting Yahoo contacts as .csv file is very easy.

If you install the Yahoo mail app from the Play Store, it will synchronize your contacts to your phone's address book, and pull them up in any app, including Gmail.  The advantage of this method is that you will have an ongoing sync, meaning any contacts you add via Yahoo website will automatically appear on your phone, and vice-verse.
If you don't want to install the Yahoo mail app, you will need to use a computer.  First, export contacts on Yahoo website as a CSV file as described in this walk-through:

Go to Yahoo mail website on your computer.
Click on the "Contacts" button, and then go to Actions -> Export...
Select the "Yahoo CSV" option, click the "Export Now" button, select somewhere on your computer where to save this file, and click "OK".

Then you import the CSV file into your Google account as described here:

Sign into Gmail.
Click Gmail at the top-left corner of your Gmail page, then choose Contacts.
Click the More button above the contacts list and select "Import..."
Click the Choose File button.
Select the CSV file you generated from Yahoo, and click the Import button.

This method is a one-time import, and any modifications you make to your contacts via Yahoo website will not propagate to your phone.  Instead, your contacts will appear in your Google account.

How can I root my Sony Xperia u?
I have used several one-click methods but none of them worked for me.
Can anyone tell me the correct process?

Android version: 2.3.7
model number: st25i
build number: 6.0.B.3.184

I've become reluctant to answer this sort of questions here on AE because of how quickly tutorials might become out of date (with device updates and such) and how little continuing support you'll receive for rooting instructions. That being said, XDA-Developers has always been my #1 choice for instructions and support for specific devices. Fortunately, XDA does have a very comprehensive tutorial on rooting the Xperia U.

Use iRoot PC version from Mgyun. The apk version failed but the desktop version works just fine. Tested on ICS.

You could try Kingroot or Kingoroot. Or some sofware on the PC. I am not sure about Gingerbread though.

As far as I've found so far there's no known way for GingerBread (2.3.7) except bootloader unlock, which wipes the storage clean on the phone.  ICS is a different matter.

Why does the YubiKey Neo only use Firefox, not Chrome?
I want to use the YubiKey NEO with Chrome, and when I tap the NFC sensor to the phone, the only app I can use is Firefox.
I would like to have SSO work with Chrome, but not sure how they were able to make Firefox listen for NFC events.

Have you tried doing it with Chrome already in the foreground? Android gives the foreground activity priority to handle NFC tags, but only if the activity asks for it.

Yes, I tried it.  My only choices are Firefox and now after I installed it, YubiClip.

7 years later, preliminary research showed that back then in 2016, it needs the Google Authenticator app to work (1, 2). Fast forward to 2020, looks like Chrome is using Google Play Services (and also Google Authenticator) as the backend (3). I don't have YubiKey to test, but I'd assume that it's now working on Chrome, except that it may still not shown as an option when tapping the NFC.

Have you tried clearing your defaults for your browser? If you have Firefox set as your default browser, anytime anything on your phone makes a request that needs to be handled by a browser, Firefox will start up by default with no other options.
You can easily tell if Firefox is set by default by tapping a link in another application, such as email or Facebook.  If you are presented with a list of apps to choose from to open the link (e.g. Firefox or Chrome) and 2 buttons - one to use the chosen app every time to open links moving forward, and one to open the link with that app just this one time only - you have no default browser set.  If instead when you click on the link Firefox opens immediately, Firefox is set as your default.  This could be what is happening here with your YubiKey.

How to send same text message to multiple people but they would only see their name as recipient?
I have a Moto X with KitKat.
I am trying to send the same text message to multiple people.

I do not want the recipients to see the numbers of other recipients.
I do not want the recipients' replies to go to multiple people.
I do not want the recipients to see who all the recipients are.
If the recipient reply's to my text message than that message should only go to me.

Just like adding people under BCC in the email.
Any help?

Isn't this exactly how SMS behaves? In a group SMS conversation, group messages are sent as individual messages to individual recipients.

That's how SMS usually works. When you send a text to a group of people, only they should be able to that they got it. They won't be able to see who else got the text.. unless you were sending SMS through Google Hangouts.

Variants of Samsung Galaxy S5
I am planing to buy Samsung Galaxy S5 phone. However, I am confused between the variants of this phone. The following versions are available in my country but when I click on each of the variants, the site doesn't specify any difference between the versions.

Samsung Galaxy S5 3G G900H
Samsung Galaxy S5 SM-G900H
Samsung Galaxy S5 4G LTE G900F

What are the differences between these variants? Especially between

1 & 2
2 & 3

The 3G G900H and the SM-G900H are the same, but SM-G900H is the proper name for it.
Now that we know those two devices are the same, we can compare the SM-G900H with the G900F-
SM-G900H
Only supports 3G HSPA+ networks, no LTE support, and will work nearly everywhere in the world except some markets in north/south america
Uses an Exynos 5 Octa 5422 processor (Split into a quad-core 1.9 GHz Cortex-A15, and a quad-core 1.3 GHz Cortex-A7)
Does not have a good development community for custom recoveries/ROMs
SM-G900F
European model
Supports LTE networks (bands 1,3,5,7,8,20)
Uses a Snapdragon 801 (quad core 2.5 GHz)
Has a fairly good development community (custom recoveries/ROMs/etc)
Benchmark

Misc
SM-G900H has a 133 MHz higher stock RAM speed than the SM-g900f, supports hardware assisted virtualization, and is generally more power efficient.

I just looked up US T-Mobile LTE band and it is stated to be 4. Does it mean none of these models will have LTE on US T-Mobile network?

Pacnet presented the main differences, here is a detailed comparison:

Some local variants:
Samsung SM-G900F for Europe
Samsung SM-G900I for Asia
Samsung SM-G900K/G900L/G900S for Korea
Samsung SM-G900M for Vodafone
Samsung SM-G900A for AT&T
Samsung SM-G900T for T-Mobile

3G Network  HSDPA 850 / 900 / 1900 / 2100 - SM-G900F
HSDPA 850 / 900 / 1700 / 1900 / 2100 - SM-G900M
HSDPA 850 / 1900 / 2100 - SM-G900A
HSDPA 850 / 1700 / 1900 / 2100 - SM-G900T
4G Network  LTE 800 / 850 / 900 / 1800 / 1900 / 2100 / 2600 - SM-G900F
LTE 700 / 850 / 1700 / 1900 / 2100 / 2600 - SM-G900M
LTE 700 / 850 / 1700 / 1800 / 1900 / 2100 / 2600 - SM-G900A
LTE 700 / 850 / 900 / 1700 / 1800 / 1900 / 2100 / 2600 - SM-G900T

all of those variant have same hardware (SM-G900F).

A longer list:
Galaxy S5 SM-G900F - LTE 800/850/900/1800/1900/2100/2600 Europe(LTE Variants) for Europe
Galaxy S5 SM-G900HNO - Europe(3G Variants octa-core)
Galaxy S5 SM-G900I - LTE 700/850/900/1800/1900/2100/2300/2600 Asia
Galaxy S5 SM-G900K - LTE 700/900/1800/2100/2600 Korea
Galaxy S5 SM-G900L - LTE 600/850/1800/2100 Korea
Galaxy S5 SM-G900S - LTE 600/850/1800/2100 Korea
Galaxy S5 SM-G900W8 - LTE 700/850/900/1800/1900/2100/2600 Canada

Galaxy S5 SM-G900A - LTE 700/850/1700/1800/1900/2100/2600 USA for AT&T
Galaxy S5 SM-G900T - LTE 700/850/900/1700/1800/1900/2100/2600 USA for T-Mobile
Galaxy S5 SM-G900T1 - LTE 850/900/1800/1900 USA for MetroPCS
Galaxy S5 SM-G900P - LTE 850/900/1800/1900 USA for Sprint
Galaxy S5 SM-G900R4 - LTE 700/850/1700/1900/2100 USA for US Cellular
Galaxy S5 SM-G900V - LTE 700/1700/2100 USA for Verizon

FYI: https://android.stackexchange.com/q/89990/12202
There is also the Samsung Galaxy S5 Duos SM-G900FD, a.k.a. Samsung Galaxy S5 Duos LTE, which is pretty much like the SM-G900F but dual-SIM.

Hoping for a custom recovery (CWM or TWRP) for galaxy tab 4 10.1
I was hoping to tweak our tab like my s3 mini, but I can't find recoveries for it and came to the conclusion the device is still too new?
There certainly are tab 10.1 things mentioned but I'm assuming these are first generation tabs?

There are custom recoveries for your device but they are only available for the Wi-Fi only Galaxy Tab 4 10.1-
TWRP (SM-T530), odin/heimdall flash
CWM (SM-T530), odin/heimdall flash

How to decrypt storage for s4
How to decrypt storage for Samsung S4, there a password that I never do before, so how can I find the password, because I never make a password for decrypt storage before.

After you've enabled encrypted storage, the password is the same as your lock screen password.

USB debugging doesn't work - switches off automatically
I have a Xolo Q800 phone with following specs. I'm trying to connect the device to my Macbook Pro with OS X Mavericks, Android Studio / Eclipse and adb working perfectly.
XOLO Q800
Android 4.2.1 (Upgraded, device came with 4.1.2)
Rooted
Mediatek MT6589M Chipset
Quad-core 1.2 GHz Processor
1GB RAM
Recently I noticed I'm not able to connect this device to any machine as USB Debugging will switch off automatically almost immediately.
Settings > Development > USB Debugging.
After I switch it on, the device reconnects to the computer but is not detected by adb.
On device go back one menu and again in Development, I see USB Debugging as disabled.
It used to work perfectly before as I have used this device earlier for development.
Not sure if the update to 4.2.1 broke it as I do not remember any issues after it.
Can anyone please give some pointers here? The manufacturer support is pretty non existing in this matter.

http://android.stackexchange.com/q/63444/53576 this may help

I had same issue, if you follow these steps you should be able to see your device.

Install SAMSUNG USB Driver v1.5.33.0 from here.
Restart your PC.
Connect qolo q800 and enable USB debugging.
Go to device manager and click on update software
Choose browse my computer for software. Then choose 'let me pick'
Choose adb interface

Thats it. Open eclipse and make your minimum SDK is 4.2.1(API level 16) or below.

Nexus 4 with no signal (sleep mode)
I have a problem with my sister's Nexus4.
When I try to call her I have the reply that the phone is off while if I call the other phone (HTC Legend with the same operator) I can talk regularly.
It happened both at home or outside.
It is not a operator problem because I change the operator twice and with the same operator in the same places I can phone with no problem.
The strange is that when a try to call N4 I am not able to start the call and after that the N4 receive a sms with the "lost call" and return it on-line.
it seems it falls in a sleep mode when the creen is off

What's your question? It just sounds like you have a faulty phone.

How can i solve it? I think all hardware are the same, so I am not a solution

Try to call the phone with a landline. If the problem persists try a factory reset, if that don't fix the problem I'm afraid you have a hardware issue.

Why I am not able to login on two smartphones?
What is the meaning that I an not able to login on another device?
I am sure that user and pwd are correct but on the second device it give me this message "user/password are not correct".
I try to set the smartphone with another account and it is easy to do that
I regularly use my account on the smartphone and on the pc

After days of attempts the problem was the two step verification!
I was trying to login a HTC Desire with android 2.2 while my account has teo step verification so I was not able to setup the account (I do not know I on last version of Android is it possible to login with two step verification).
I solved:

stop "two step verification"
login on the smartphone
set "two step verification"

Having two phones logged into the same Google account works perfectly fine. If it tells you the username or password are incorrect, then most likely one of them is incorrect. In particular, if you're using different soft keyboards on the two phones, take extra care when typing punctuation characters and numbers: they could be in different places on different keyboards, so you could type the wrong one without realising it.

The user and the password are corrects. I typed them a lot of time and I also copyed them from the message app so they must be correct

Gmail asking for authentication after changing SIMs
To recreate issue:

Start 2-factor authentication
Generate app-specific code
Use that to sign into your device
Change the SIM

I have two SIMs, and I sometimes switch between them. The issue is that once I do so, it prompts for the password. I then have to create a new app-specific password using my computer to access GMail.
Is there any way to fix this bug? If so, how can I do it?
I appreciate any help.

Help! I can no longer access photos from my gallery when trying to send a picture
I have a Samsung S4.
when I'm trying to attach a photo to an MMS I used to get an option of accessing the photo via galary or Samsung link. Usually I selected gallery. This time I accidentally clicked Samsung link and now I can't access pics to send via gallery it only takes me straight to Samsung link.
My question is how do I access pics to send via gallery not Samsung link?

You can reset the default application settings in settings > apps > [your app] > "launch by default"

or you can manually select the image from gallery and share it via MMS.

Android Wear smartwatch Samsung Gear Live won't turn on, while charging
I have the Android Wear smartwatch Samsung Gear Live and it wont turn on. When I'm trying to turn it on while charging (and it was charging for at least 3 hours) it will show the initial logo, then the booting animations and at one point before completing the screen will turn black. When pressing the button to turn on again it shows the charging battery animation.
Is there anything I can do to hard reset maybe?!
I tried to hold the button for long time or unplugging it from the power supply, but it keeps trying to boot and stops without success.

Someone with 300+ maybe could create the samsung-gear-live tag :)

What happens when you plug in to charge?  Does the display show the large battery that fills up?  I'm wondering if it's not charging properly, because what you describe sounds a lot like what would happen if you tried to turn it on with minimal battery.  I've heard reports of the watch being unable to properly charge from an outlet after long periods of inactivity, where the (inexplicable) fix is to let the first ~5% charge while connected to a laptop, then plug into the wall, did you go a week+ with it powered down and out of battery?

@MattDavis actually it was a battery issue after all.. so my charger is not working.. I tried with another one and it work.. which brings us to another problem obviously, but it's unrelated with the watch! So I might delete that question completely..

most of the time they will charge from a laptop usb and not an outlet.Also if you take it apart and disconnect the battery it will fire up 90 percent of the time.

This doesn't make sense, laptop ports are frequently underpowered compared to wall chargers and not the other way around.

Tablet showing 0 internal storage even after flashed
My Envizen V917G just shut down one day and restarted with the factory reset.
I have since flashed it with the software from their website (several times, it fails to format the cache in the automatic mode but claims to be successful if I do it manually) but it still shows 0 space available and it won't shut down on it's own but I presume that is because it can't save any settings since it says it has no space and it restarts in it's factory setup state every time.
Anyone know of any other software I could flash it with to get it working properly, or other things I could try? Or is it just a useless toy now?
This was a gift and I can't claim the guarantee without a receipt and the original serial number intact, which was just a sticker that rolled off the back after 4 months of use.

Disclaimer - I don't have enough reputation to place comments - so here is a suggestion.
I have been looking around and found a blog from a user with the same device who has rooted it successfully here.
Plus the comment from a user here.
I suggest to get your device rooted and then install (clear some temp files before installing if you can) the disk utility from here
From the app, you can see where your data is being used.
PS: You don't necessary need root privileges to get this utility working. However, I am presuming you have flashed the device perhaps to death and may have lot of old data which may be stored from within the system data part of your Android device.

Here is what is happening:
The update somehow unmounted and mounted partitions improperly.
You will have to install (flash) custom recovery (TWRP,  CWM, or other).
Go into the mount option to toggle settings.
I don't know exactly which partition (I think it was /data?) got mounted or unmounted, so I can't help you there. But I had the same problem when I got an update on my Acer ICONIA a500. My 16gb turned into 1.2Gb! It took a little bit, but finally got it figured out.
Good luck!

High CPU load during file copy to SD card
Copying large files to micro SD card (via MTP mode or USB thetering and FTP) causes a high CPU load (around 90%) with the result of my phone rebooting from overheating.
Is this a normal behavior? Any suggestions?
My system is Cyanogenmod 11-M8 on a Galaxy S4 mini with a SanDisk Ultra microSDXC 64GB.
EDIT
Here are the last messages before reboot according to adb logcat

No, it's not. File transfer can cause some cpu load but not nearly as much. And then high cpu load can heat up a phone but should not cause a thermal protection cutoff. The problem also happens when you move files with the file manager with the phone detached from the pc?

Yes, also copying a file within the phone from or to SD causes the high CPU load.

Have you enabled device encryption?

No. And the processes responsible for high CPU are kworker, system/bin/mount.exfat and system/bin/sdcard.

In that case I don't know what to say

I do not have a Samsung device but I had the similar issue in my OPO. The average temperature it works on is in between 45-52deg Celsius. While copying over FTP using USB tethering, the temperatures reached beyond 70deg sometimes. Since it isn't normal for me, I found a solution as:
Note: - Device needs to be rooted, bootloader unlocked
The goal is simple. Your device is overheating because it is using too much CPU at its peak. I underclocked it and was able to lessen the resource usage.
Things I needed:

Busybox
A kernel that supports Universal Kernel Manager (UKM). AK already has UKM which I used for flashing over my stock kernel
Synapse -- app to modify kernel settings

The flashing varies from device to device, so you've to search how to root and flash the kernel, and install the aforementioned apps.
Once you've everything at its place, launch Synapse → CPU → change the clock speed using slider. (I changed it from 2.4GHz to 1.3GHz.) Additionally, you can also set a custom limit for thermal protection cutoff. Go to Thermal in the same app and use the slider. I have it set on 74deg.
You can monitor CPU temperature and clock speed using CPU Temp.
Since then, I didn't see any overheating in my phone while transferring the data. However, the obvious and the biggest downside is that the data transfer speed will take a huge hit. Mine was decreased from ~24MB/s to 8MB/s for Internal SD-card (type emmc5).

How can I use my Samsung S4 phone functionality from my Asus Nexus 7 tablet?
I got two android devices: Samsung S4 and Asus Nexus 7 where the latter does not have a SIM card. I'd like to use the phone functionality from the tablet e.g. calling and/or SMS but I don't know how. I paired the device using bluetooth and I tried with an app called MightyText but that never completed the setup. Is there a way to do what I want?

It's simple. Download the WhatsApp Messenger App on to your tablet. It's free for a whole year, then you pay $1/year to keep using it.
By default, WhatsApp isn't compatible with tablets, but there is a work-around for that...
...Right Here
You can also try Line, which is another messenging app.
Also...TextPlus has the least amount of work to setup (it's compatible with tablets), but it allows you to send texts and make calls. Though it's not as good as WhatsApp or Line
I've also tried MightyText, which works just fine. Not sure why it won't work for your phone...

And how does that help using the SIM-based phone functionality of the other device? OP didn't ask for "some way to chat", but wants to make cell-phone-calls using normal telephony and SMS.

@Izzy when the OP said they tried using Mightytext, I knew what they meant. They're saying that they want to be able to do phone stuff on their tablet.. Like they said, SMS or make phone calls. The answer I put let's them do that, which is a work around for the fact that the tablet doesn't have a SIM card

OK, you might have your point there (which I missed, not being a big fan of those cloudy stuff) – or OP had the wrong expectations towards MT :) So I will shut-up, and leave it to the OP to decide ;) Sorry for the interruption!

Thank you for the information. I hesitate somewhat about using WhatsApp as a carrier just to route 5 feet bluetooth or wlan connection between 2 android devices locally close, I'm going to try and install TextPlus and also another way with an external SIMcard connected via usb if compatible: http://android.stackexchange.com/questions/78685/how-can-i-use-my-samsung-s4-phone-functionality-from-my-asus-nexus-7-tablet?rq=1

Linux Deploy removal
I was going to install Linux Deploy , but then if I don't like it how can I remove the Linux installation?

I did this for myself by navigating to Settings > Storage, tap on the Misc category, select the ~4 GB linux image and use the trash icon to delete it, but this will probably vary depending on what device you use.

Broken recovery, missing system e739
e739
I had used the twrp recovery.img from e730 and it worked fine, flashed cm7, worked great.
Then i saw that someone had made twrp for e739. I was going to flash that as well as an unofficial cm10 rom. I wiped system, then i thought i should probs do the recovery first, so i did, rebooted into recovery, and now, along with 4 tiny screens and pink everything, I can't flash anything. It would seem the recovery doesn't work. How can I fix this?
EDIT: I am getting an error saying it can't open the zip file. The file is fine, i did MD5 check

If you can access an adb shell, you can flash a recovery.
If you open the recovery zip up and go to META-INF/com/google/android/ you will find 2 files, you want "updater-script". Open this up with a text editor, and look for something that says dd followed by recovery.img. In that line near the end there should be something like "of=/dev/block/mtdblocknumbersnstuff"
copy that line. From here on I will refer to that as "of=x"
now go back to the zip folder and extract recovery.img to somewhere convienient. Connect your phone to the computer and boot into recovery, then run
adb push /path/to/recovery.img /data/recovery.img
adb shell
#cd data
#ls

Here it can output a bunch of stuff or nothing, but you are looking for "recovery.img" If you see it, good job, continue. If not, start over from the "adb push" command.
dd if=recovery.img of=x

From there reboot back into recovery and you should see the recovery you just flashed.

How to change SD Card after moving apps using Link2SD?
I haven't used Link2SD yet to move apps, because there is one thing I'm confused about. Currently, I have a 2 GB SD card on my phone, but I'm thinking to buy another 8 GB card later.
What will I have to do if I want to transfer all the apps (linked/moved using Link2SD) to my new 8 GB SD card?

possible duplicate of Transfer of files and apps from old sd card to new sdcard

@IAmTheSquidward This isn't a duplicate, since App2SD and Link2SD use different methods, and the answer given is only relevant for App2SD.

But that's not what I'm looking for. That method is for Moving files using Linux and MAC. What about Windows? and What about the Second partition?

How to move 7GB ext4 partition on external SD card to 30GB partition on another SD card?

I tried copying the SD card to a folder and then to the new card. I used Linux Mint 17 running Nemo as root. If you don't have Linux installed, I would recommend a Kali Live disc, since it runs as root.
Everything seems to have been copied, but the first boot of the phone gave me an inconsistent UID message. It was gone at second boot. Some apps worked, some worked after reinstalling, and others lost all of their data.
If you try this, move the stuff you really don't want to lose back to the phone. Starting a game all over again when you were at level 200 really bites. Facebook and Messenger store everything on servers, so they could be easily reinstalled.

When you want to change your SD card from 2GB to 8GB, you should have two partitions on the 8GB SD card.
First of all, uninstall all of your non-system apps and open Link2SD.
Select clean up SD partition 2 and then select cleanup partition's Dalvik-cache. Now you can insert a new SD card and enjoy these features without any issue.

Its a simple procedure really. All you have to do is connect your SD card via a reader or adapter to a computer. Then copy all the data to a folder. Then transfer all they data to your new SD card and it should work.
This method is not exactly foolproof so don't delete the data from the first card in case you need it

It's not that simple since in the original card there are two partitions, and most probably one of them is formated in ext2 or ext3. That partition won´t be readable for Windows. So unless your computer is Linux, you need utilities that can deal with that

Is it possible to remove the battery percentage on my Samsung S5?
I have a Galaxy S5 running 4.4.2, unrooted.
In the top indicator bar, there is an icon of a battery, and a percentage of remaining battery life beside it (not inside of it, as I've seen other people mention).
I find the percentage being there kind of stresses me out. I look at it and wonder if the drop from 90% to 80% over the last little while is indicative of lots of battery use, and whether or not my phone will last the day.
Can I get rid of it? I'm okay with just a battery icon.
Ideally, a percentage would only show once I'm under a critical point, like 20% or so.
Here is what my battery settings look like:

Click image(s) for larger versions

I upgraded to Android 5.0, and now the option to hide battery percentage is available with a simple checkbox in the battery settings interface.

Battery percentage is used by users to charge the device based on the percentage(if the charge <25 % then charge the device till 100% and if not less then 25 % then do not charge in order to extend your battery life)
The below steps are common for all the Android devices with version greater then Android 4.1(jelly bean) to the present Android 4.4 (KitKat) only with some minor modifications.
You can simply uncheck the Show Battery Percentage in the Settings.
Go  to the settings>Battery.

In that you can see that the Show battery Percentage is checked. You can simply uncheck that and the battery percentage will not be displayed.

If at all the check box is not under the battery menu then you might be having it under the Display menu.
Last but not the least please check if your device is available for the Update to Android 4.4.4 if yes then go ahead with the update.

Thank you for this response. However, in Android 4.4.2 on a Samsung Galaxy S5, there is no checkbox in the location you've indicated. The screenshots look like maybe they're from an earlier version of Android perhaps.

@DaveMG check the updated screen shots. Moreover the above steps are common in devices running with Android 4.1 and above.

Thanks for the update. However, I swear my Samsung does not have the "Show battery percentage" checkbox anywhere in the battery settings. It looks exactly like your second image with the graph and the list of applications, but no checkbox for battery percentage.

@DaveMG then could you please attach the screen shot of the settings menu as well as the battery menu to get a clear view of the problem(press the power/lock and the home button together for few seconds and the screen shot will be captured to your phone memmory) .Also add the software version of your phone from about phone.

I've added screenshots to the question. Also, I've already stated the Android version is 4.4.2. I'm not sure what other software version you might be referring to.

@DaveMG check my update and I was referring to the Settings>About device .In about device menu you can see the exact Android version installed on your device (to make sure you are giving the correct Software about your device and is helpful for some people as some manufacturers specify another Android version in the specs and install a different Android version on the device)

The exact Android version is 4.4.2, as stated. There is no other software version information that I can see. I checked for updates, but none were available.

Go to settings>>>battery>>>scroll down and uncheck the "Display Battery Percentage" option.

Thank you for this response. However, in Android 4.4.2 on a Samsung Galaxy S5, there is no checkbox in the location you've described.

With regards to the screenshot above try at the bottom of the list of apps under battery, if not try under settings > display and might be there somewhere

Thanks for this response. There is no percentage option in either of these locations.

The only other option I can think of for you is to root your phone and then install Wanam Xposed from the google play store, when you open the app it will prompt you to install the Xposed Firmware so go ahead and do that, back then to Wanam you'll be able to do many customizations to your notification/status bar including remove the percentage from battery

@DaveMG Are you sure? On a 4.4.2 Galaxy S4, it's definitely in Display settings (if you have tab view, Display is on the My device tab). Did you scroll down? It's not visible when you first open the Display settings page. You have to scroll way down, it's one of the last settings. Not very intuitive; it really should be in Battery settings (or in both locations, if they must have it under Display).

@AdiInbar, on my device, under the Display section, the bottommost item is Increase touch sensitivity. There is no check box for showing the percentage. I have looked in every location suggested in every answer and comment, and the option does not exist on my phone in any of the locations suggested so far.

@DaveMG For the record, I didn't say "bottommost", I said "one of the last". It should be the third item above Increase touch sensitivity. But actually I just noticed that I do have it in both places. There's also a checkbox scrolled off the bottom in the Battery settings. Odd that you wouldn't have it in either place; documentation for the S5 indicates that this hasn't changed. Are you using a custom ROM? I notice that you have a different them (no cogwheel, different organization). If you bought it used it's possible that you might have a custom ROM without even knowing it...

@AdiInbar, I don't have a rooted or custom ROM that I know of, but it is possible that my carrier (DoCoMo) modified it in some way.

This was a boggle for me as well, but I found it if click on battery, then the display at the top and then display at the bottom once more and finally about half way down you have display battery percentage.

Thank you for this response, but your description is not clear. What do you mean by "then the display at the top and then display at the bottom once more"?

I was losing hope of finding this on my Sony Xperia Z2 Tablet which runs Android 4.4.4, but finally I did. On my device it's under Settings -> Device -> Personalisation -> Status bar icons.
Hope this helps you find it on your Samsung device as well.

Thank you for responding. Unfortunately, under settings, I don't have a Device, Personalization, or Status bar icons screens anywhere that I can see.

If you're using android 4.4.4 goto Settings>Battery, then up the top right hand side click on the battery icon. This should bring a drop down menu to change the battery symbol.

Unexpected touch behavior in Chrome
On my 2012 Nexus 7 running Android 4.4.4 and the latest version of Chrome, I've noticed that when I touch and hold links that are close to each other, it may not select the link I intend to select. Instead of activating the link at the center of the touch area (the behavior I expect), Chrome seems to select the link based on the entire area covered by my finger:

Is this (counterintuitive) behavior normal? Can I configure Chrome to simply use the center of the touch area instead?

Going by the unexpected touch behaviour you provide it seems that your multi-touch screen is not responding properly to your inputs for this you need to confirm it by doing a small and freely available  multi touch  test.
Download the app and check whether the touch is shown exactly where you selected. The two dots are drawn exactly where the phone reports you are touching.
or else you can simply do the following
1- Go to the developer options section in settings.
2- enable pointer location.
3- touch the screen as lightly as you can. you will notice a red number on the upper right corner of the screen named ""Prs:". this indicates the level of contact needed to register a touch.
4- do the same on different areas of the screen & remember try to touch the screen as lightly as you can (the goal here is to find the lower number that registers a touch)
If you see that at one point of the screen the screen is not responding according to your input then you need to get in contact with your Authorised service centre and report the issue.

I highly doubt this is the issue. I was using the pointer location dev tool to show the image shown here and the touchscreen is clearly working, This is a software issue (possibly by design, possibly a bug).

@DragonLord possible update will help resolve it.

Force to buy app with old version of Android
I have two smartphones:

HTC Desire (unrooted / android 2.2 / normal-sim / operator1 / my account)
Nexus 4 (android 4.4.4 / micro-sim / operator2 / my account)

Both smartphone are regurarly  logged with the same account.
I need to buy some apps with normal-sim from operator1 but those app are available only for android 4.0 and newest.
I will use the apps on my Nexus 4 but I do not want to root any device by now.
How can I solve it?

EDIT after reading your comments:
AFAIK, It's not possible.

It is the opposite: I want to buy with HTC desire (android 2.2) and use the app with nexus 4 (android 4.4)

@Ale Edited. :)

The apps are not available for Android 2.2, so I can't buy the apps on Play Store from HTC Desire

@Ale both smartphone are logged with my account What happens when you try buying from Nexus??

With Nexus I can buy it normally (but I have to pay with credit card, while with HTC Desire I can pay with operator offers...)

Oh! I'm sorry. I don't know :(

I assume that rooting and flashing a ICS rom on your HTC desire is out of the question, so how about you take the SIM card from your HTC to your nexus 4, complete the offer, then switch back? If the offer is tied to the operator the nexus 4 should be able to make the purchase just fine.
If the offer is tied to the device model (HTC), then try this app on your nexus 4 (requires root!). It will make the play store see your nexus 4 as a HTC device. Combined with switching SIM it should satisfy both operator and device requirement for the offer. I'm not sure if it will work for your particular case though.

The sim format are different (micro sim in N4 and standard sim on HTC) and I do not want to put another sim on my N4...

You can always cut your sim to the smaller standard and use an adapter when you need to use it on your older phone. Any phone shop can do this for cheap.
Also, you can flash an ICS rom on your HTC, but it's an arduous process.
The question is, is the offer really worth the trouble? :)

I am not sure how the offers you have work, but could you go to the play store in a browser and buy them there on your HTC and tell it to install them on the N4? I've had to do that for devices since you cannot access the Devices page from the app itself. If necessary, you may have to clear defaults with the browser and Play Store so that you have the option of viewing it in a browser instead of being taken directly to the app. I haven't used 2.2 in almost 4 years, but I assume that that is possible.

moving apps to my SD card on my Xperia E 4.1.1
Okay, I have an Xperia E android 4.1.1. It has 2 GB internal space and so I got an 8 GB SD card. I noticed that any app I download occupies space in my internal memory. I tried moving them to SD card but I can't do it in the way given on Google - Settings>apps>manage>move to SD card. When I go to my settings I don't get any Manage Applications. I just get my apps and there are options like Move to phone or Move to Internal Storage. I also tried App2SD. But it didn't work. Isn't there any other alternative than rooting my mobile? Please help

Rooting is the only option.

Android no longer natively supports moving apps to SD Card.  Some manufacturers that ship phones with SD Card slot (like Samsung, for example) often do include this functionality.  Apparently Sony is not one of these manufacturers, so you will not be able to use your SD Card for app storage with their stock firmware.
If you decide to root your device, you will be able to use apps such as Link2SD to move apps to your SD Card.  Note that you will need to re-partition your SD Card (and re-format it) in a special way to be able to take advantage of this feature.  You will also not be able to easily swap the SD Cards in and out, as it will become an "extension" of your phone's internal memory.

Linux Deploy - Fail to make disk image
I am trying to use Linux Deploy on my rooted Galaxy S4 with stock Android 4.4 rom. But when I press install:
Updating configuration file ... done
>>> begin install
Checking mount points ... done
Checking installation path ... done
Making new disk image (1023 MB) ... fail
<<< end: install

I have already checked root permissions, tried to install in internal with /storage/emulated/0 and /storage/emulated/legacy, I have also tried to modify the image size but same results, how can I solve that?

try installing in /storage/sdcard1/kali

In my device I don't have /storage/sdcard1, I tried /storage/sdcard0/linux but it doesn't work

It seems a problem related to Samsung's Touchwiz roms, on Cyanogenmod 11 the software works. Maybe it's related to Knox oe selinux?

It's related with the touchwiz kernel, beacuse when I flashed adam kernel it started working. I think it has to do with selinux set on enforcing

Why can't I charge a Samsung phone?
I use a dual-port 2-amp charger with an Amazon Basics USB cable. This works perfectly fine to charge my Nexus 4 and the Nexus reports "AC" not "USB" as charging mode. From the recharge time it's also evident that it gets plenty of juice.
However, when I connect my wife's Samsung Galaxy S Duos then it simply does not charge at all - the battery indicator does not get the lightning symbol, and the battery really never charges (even when nothing is connected to the charger's second USB port). When I connect the same phone to my computer's USB port, it charges just fine - even using the LG charging cable! - but slowly of course. The Samsung also charges well from any el-cheapo car charger (lighter socket) as well as from my expensive 3A car charger and from my LG AC charger.
What's the cause of this? How can a charger&cable combination work very well for one phone, yet not at all for another?

Very interesting case, Torben.  Does the Galaxy S Duos work with other AC chargers??

possible duplicate of Why are USB cables of two different OEM's different

@IAmTheSquidward yes! The Samsung happily lets itself be charged from any el-cheapo car charger (lighter socket) as well as from my expensive 3A car charger and from my LG AC charger. It's baffling.

@TorbenGundtofte-Bruun Very interesting!!!  I would try to isolate what is causing the problem... Use the Duos with the Amazon cable and a car plug, and then the Duos with the dual port 2-amp and a different USB cable, etc etc, and see what is causing the issue.

In my experience, and my extensive reading on the subject, it seems to be related to the charger and not the cable, unless the cable is a non-standard USB cable.  Samsung does not use a special cable for their micro-USB chargers, only their old devices with the Apple-like connector.
The USB standard requires handshaking to negotiate more than 500 ma of current.  This is not done in a standard way outside of IOS devices, so not all manufacturers use the same methods.  I believe some Samsungs look for a certain voltage on one or two of the pins of the connector, and will not work with other chargers, but I'm only guessing.  What I have found with, for example, my Galaxy Tab 3, is that there are some chargers that will not register no matter what cable I use (including "charge-only" cables like from Mediabridge), and other chargers that will not charge it at the full rate unless I use a charge-only cable.
My wife's iphone seems to charge from all the chargers, although I'm not sure if it's at the full rate since I have no app to check.  I should mention that most aftermarket chargers are designed to work with Apple, and not necessarily Android, so this is no surprise.
My LG G2, on the other hand, seems to be much less picky, and charges from most every charger I have.
TL;DR, a lot of chargers will not work well, and it's hard to know in advance whether they will.

You seem to be contradicting yourself. Your first paragraph states that the cable is irrelevant but your second one says that some chargers need specific cables. I have found this to be the case on my Galaxy Tab 10 as well. Only the stock charger combined with the cable it came with will charge the device at full speed. The same charger with a different cable will not.

@terdon:  Sorry if I was not clear, but I wasn't actually referring to the cable, it's the charger that is not standard.  Using the same cable, and switching only the charger, I find that some will not work with my Samsung tablet, and others will work with everything.  I don't fully understand it, but I've definitely confirmed it.

I realize now that my previous comment might have come across as rude or aggressive. If so, I apologize, it was not my intent, I was just trying to understand. I've had similar issues and in my experience, the cable is also important. The original charger with a different, but high quality, cable doesn't work as well. Haven't you also found that the cable is a factor? You say that some chargers will work with any cable while others require a specific type.

@terdon: I believe that if you use the charger that came with the device, then the cable normally makes no difference (assuming it's a standard, decent-quality cable).  However... sometimes, with a different charger, you might find that it only charges at .5 amps, the maximum USB-2 current without a special driver to negotiate a higher current.  In this case, you can sometimes use a non-standard "charge-only" cable, that will trick the charger into putting out more current. I believe this is not needed very much currently, but I'm not really sure.

To answer some of your questions in your comments:  The USB specification allows for a fifth channel, OTG (On-The-Go), to negotiate master/slave relationships.  Some manufacturers remove the OTG channel (cheapo USB cables are notorious for this), and, subsequently, charging negotiation is halted if the device is trying to send data through it.  Some early Samsung phones require the OTG channel, and if your cable doesn't have it (or it's a bad circuit in that one line), then it won't charge.  Very weird, but, some manufacturers do that.

Marty is correct! I had the same problem with a third-party USB charger that would charge everything I had, except my Samsung phones.  They look for a specific voltage on a certain USB pin.
By opening a charger that worked and the one that didn't, I was able to modify the one that didn't to also work.  I'm not sure how USB connector pins are numbered, but for the sake of this explanation, let's say the one with the positive supply (say the leftmost one) is '1' and the negative supply (far-right) is '4', then for Samsung charging, '2' needs to float (no connection) and '3' needs to be connected to the minus pin ('4').
Of course this involves opening the USB charger and soldering stuff, so not for the uninitiated!
Hope this helps some future viewers of this post!

Most probably the USB cable is not supporting the Samsung device. Not all OEM USB cables support other OEM Android devices. It may work with Nokia USB Cable  but not with the Nexus because the design of the pins is not matching.
For this you cannot open the USB cable and change the design or something what you can do Is to try another OEM USB cable like Nokia.It will definitely work.
For more details check the answer

How can the cable be at fault? It's just four copper wires with a plug on both ends. I'm curious.

The answer of question you link to pretty much disagrees with what you say here.

@DanNixon that's why I mentioned "Not all" and in the link given to the answer it clearly mentions the +D and -D signalling made in the USB cable

Lost tablet - No SIM, no google account, no tracking software, can I track it?
A couple of days ago, I lost my dear Android tablet. I dont know if I have left it somewhere or if it in fact was stolen :/
It does not have any 3G module, and hence no SIM, inserted. I haven't logged into my Google Account on the tablet. And I have not installed any tracking software.
The tablet have a GPS installed. Is there any way to track the tablet using only the serial-number?

Yes. You report the loss or theft to the police, and give them the serial number. (You'll need proof that it was yours, of course.) If someone finds it and hands it in, or if it's recovered from the thief, then they know it is yours, and will return it to you.
That's your only option. Since you haven't signed into your account on the tablet, as far as it's concerned, it doesn't belong to you. You can't remote-deploy tracking software onto it or enable Google's Android Device Manager. The GPS itself doesn't help you at all: it only tells the tablet where it is, not anyone else.

I know it's bad form to answer questions that you're VTCing. Sorry, I wrote the answer before VTCing.

You also forgot the options of the thief feeling bad and just returning the tablet, or the owner finding it by chance ;)

@Chahk Well, neither of those ways use the serial number, so they don't match what the user asked for :-p

Changing font of Xperia SP stock Clock Widget
I rooted my Xperia SP and managed to change all fonts to Roboto Condensed.
Only issue I am having is with the clock widget. I am not sure which font is used by the stock clock widget.
I managed to change the time font of the clock widget to Roboto Condensed.
I changed Time font by replacing .SST-UltraLight.ttf with Roboto Condensed font.
But can't change the font of Date and Alarm information. It uses some other font.
Can anybody help me on this?

Screenshots of the lock-screen (click images for larger variants)

Part of me thinks that the widget uses it's own font built in to its package, rather than a system font.  I don't think you'll be able to change it.

I checked that too. That's how I found that it uses the font '.SST-UltraLight.ttf' I have not idea why its not getting reflected on date and alarm strings.

Can I freeze/remove com.android.keyguard if I don't use the lockscreen?
What is exactly com.android.keyguard?
Is it just handling the lockscreen?
If I set my device not to lock when screen is turned off, can I safely freeze/remove com.android.keyguard?
I'm using a galaxy nexus with cyanogenmod 11 (kitkat), trying to lower RAM usage.

com.android.keyguard runs your lockscreen, home button, and a few other things I can't remember.
It's an integral part of Android.  Don't remove it.

ok I totally don't wanna loose the home button

If you disable/freeze com.android.keyguard, your device's Home button will stop working until you enable/unfreeze it.
This process keeps running all the time, but it is not a Battery drainer so don't worry and don't disable it.

Sync 'droid with Outlook
I have seen many questions here about users trying other software than Kies for sync'ing data with Outlook and a handset, very mixed reviews with what's good/bad, but not very much mentioned recently on the versions I am using.
I have setup a Samsung GS4 with Kies on a Win7 PC running Outlook 2010, the previous user had a Blackberry and is used to sync'ing his device with his laptop. Email items are sync with a GMail account as we are not running Exchange.
The user has 400+ contacts and quite a lot of e-mail with hundreds of calendar items.
Kies Sync has worked (albeit slowly) for a week, now it stalls/halts (no errors, no timeouts) at 15%.
Any hints or troubleshooting I can do? Sync logs to look for?
If I cannot resolve this I will need a different product to use, so any suggestions are more than welcome!

Do you by any chance have a Google Apps for Business, Education, or Government account? If so, the official Google Apps Sync utility should help.

Afraid not Chahk, but thanks for the info!

There is a one-way Google-to-Outlook sync built into Outlook 2010 and 2013, where you generate a link to your calendar via Google Calendar website, and then add the URL to Outlook as an Internet calendar.  This way any changes you make on Google side get synchronized to Outlook.  Step-by-step walk-through instructions are here:

Log into your Google account, click on the Apps launcher icon Apps launcher icon and select Calendar from the list of apps.
Hover over the needed calendar in the calendar list and click Calendar settings. This will open the Calendar details page.
Click the ICAL button and copy the calendar's URL.
Open your Outlook and switch to Calendar -> Manage Calendars ribbon group.
Click Open Calendar button and choose "From Internet..." from the drop down list.
Paste your Google calendar's URL and click OK.

If you are looking to sync the other way, i.e. Outlook-to-Google, your options are much more limited.  Microsoft tells you how to perform a one-time transfer by exporting your Outlook calendar and then importing the data into your Google account.  However, this is not a permanent solution, as it requires you to do this every time you make changes in Outlook.
Google used to have a service called Google Sync which would perform a true two-way sync between your Google account and Outlook via a small application that you would install on your Windows machine.  Unfortunately that service has been discontinued a while ago.  It's still available for paid Google accounts such as Google Apps for Business, but not for free Google accounts.
In terms of 3rd-party applications, since you have already ruled out Kies as unreliable, gSyncit comes highly recommended, but it's not free.  It is a MS Outlook add-in for your PC (no Android app required) that allows a true 2-way sync of e-mail, calendar, contacts and tasks between Outlook and a Google account.

Thanks for all the info, I'm thinking a 3rd party package like gSyncit will be the best solution. We'll have to see if we can trial it first. I really have lost my faith in Kies - it seemed to be working very well!

Is gSyncit safe to use? I'm cautious downloading it from the site listed as it doesn't appear linked to the Play Store? I don't even see it listed on the Play Store!

Well no, you wouldn't find it on the Play Store, since it's not an Android app.  It's an application that you install on your PC, and then activate the add-on in Outlook. That said, it's listed on Google Apps Marketplace and has many reviews. I have not used it, so cannot comment on how well it works.

There was me thinking you had to install something on the Device! But seems it just syncs the local PC with the Google account in question. I'd come across the reviews before. We're basically down to a choice between gSyncit, CompanionLink and Akrutosync. All are a similar price.

Phone is Stuck in Boot Loop With Recovery Not Accessible
I have a Tecno P5 and wanted to flash ClockworkMod Recovery onto it. I used Recovery-Tools to do this with the file TECNO-P5_130916__recovery_140106-193223.img. The process completed and I was prompted to boot into recovery. The reboot did not complete.
I can get into the boot menu (Volume Up + Power), but when I select Recovery mode or Normal mode the phone gets into a boot loop. Fastboot mode works and I can connect from Windows 7. The result of fastboot devices is "mt6572v1_phone fastboot"
No other Fastboot commands are having any observable effect apart from fastboot flash recovery TECNO-P5_130916__recovery_140106-193223.img which results in the error "Security deny - Err:0x2017".
fastboot oem unlock just hangs at "..."
Is there a tool that can either unlock the bootloader or reset the phone to factory settings so it can boot normally?

You could re-flash the stock recovery again from fastboot, but you'll need to find the image from the manufacturer or from someone who's taken a backup.

@DanHulme I have a zip that I believe is a backup of stock ROM meant for unbricking. I tried flashing the recovery from that, but I still get "Security deny - Err:0x2017". If only I could get pas that error...

Try downloading the latest adb and fastboot tools. Some fastboot tools hang while unlocking bootloader

Chrome pages turns blank after loading
I have been having this happen to me for a long time now but recently it seems like it has gotten worse.
What happens is that
A page loads, and you can see the webpage and almost all content while its loading. You can scroll and use as normal, but once the page fully loads it turns to a fully blank page.
Sometimes it happens really fast on light pages, other times on heavy pages you are able to see the page then when it does load it goes blank.
Even with a refresh the same thing happens.
The way to fix it is to clear the app from recent apps. Open back up chrome then it loads fine.
Its not every page its not all the time but its at least everyday. Its happened with 1 tab open to 10 tabs open. On all kinds of different sites and pages.
Any ideas on why this is? Anyone else experiencing the same thing?

Yes, I've seen the same behavior. If I open a new tab and go to a different site it usually works. Otherwise, I just fire up Opera instead.

I've been getting the same problem on moto g. Had to uninstall updates (back to version 34) in the end which fixed the problem. Waiting for version 37 before I try again.

I usually get around it by copying and pasting the URL into a new tab.

A bug in the latest version of Chrome can cause this in certain circumstances (low memory being one). Details here:
https://code.google.com/p/chromium/issues/detail?id=342190
https://code.google.com/p/chromium/issues/detail?id=399521
Seems like a fix should be making its way into the beta soon.

I wouldn't say latest version because I have updated my chrome many times and the problem has been around for a long time now just in the latest update.

It sounds similar to a bug with 16-bit transparency. If your phone has this setting, turn it off, then try again, but your bug does seem a little different, so no promises.

I have the same problem. I usually just press the home button to go back to my home screen of my phone, then I hold the home button and clear apps running in the background. Then I open chrome again and the screen is displayed properly.
Only solution I have until the bug gets fixed in beta.

How does WhatsApp show the name in the contact list?
This is bugging me about WhatsApp. My contact list in the WhatsApp app is presumably the list of contacts I have in my phone book who have WhatsApp. I can see their picture and status if they have one. But their actual usernames are as I have inputted them into my phonebook.
However, I'm sure it should appear as they have chosen their names to be (because I can choose how I want my name to be in the edit profile section). It may seem trivial, but I'm worried I'm missing something or have done something wrong.
How does WhatsApp show the name in the contact list?
P.S. I have a Samsung Galaxy S2, Android 4.1.2.

Your WhatsApp contact list will display the names you chose for the numbers in your phonebook.
The nickname a user has is only displayed if he/she's not in your phonebook and he/she's posting in a group you're in.

The nickname also shows up in push notifications in iOS, also from Android users.

Yeah, even on windows phone; whatsapp faq says about nickname: " This name will only appear for contacts who do not already have your contact info. If your contacts are using iPhone or Windows Phone, this is the name they will see on the push notification."

Rooting A Motorola Droid Razr M Phone on Verizon Network
I have a Droid Razr M, running on the verizon network. I would like to root this phone so I can use some of the more advanced features of Tasker; however, I am very fearful of "bricking" my phone. I see many approaches, which concerns me, because I would feel more comfortable if I could be sure process X is the one to use and works. Here are the particulars of my phone:

Model #: Droid Razr M
Android Version: 4.4.2
System Version: 183.46.10.XT907.Verizon.en.us
Baseband Version: SM_BP_101031.042.32.86P

Can anyone advise me as to the best approach to take, even if it means there is no current software to root my phone with the version it has?
Thanks,
FDijohn

If I could comment, I would, but yes, TowelRoot is a safe download. It is one of the most commonly used root methods for newer devices. Neither of the antivirus programs that I use have had any problem with it.
(If someone has the ability to repost this as a comment on @IAmTheSquidward's answer, that would be awesome)
EDIT: Several sites and forums state that it will work on the RAZR M and HD if your build number is .182 or .183. If you already updated to whatever came next, then it is too late and you might not get the chance to root again. Not to be rude, but that's what you get for having a Motorola and/or Verizon phone. They both (along with Samsung) try their hardest to make sure that you cannot root or unlock your phone.

With GeoHot's new Towelroot exploit, it's as easy as installing an .apk and clicking a button.
Towelroot link
Just download and install that app, and then run it.  After it's done, go on Google Play and download SuperSU.

I tried to download from the link above, and McAfee blocked it saying it detected a trojan called: Artemis!E287E785D0E3, and proceeded to delete it. Is Towelroot a safe download?

Towelroot is "safe" for what it does... Without going in to too much detail, it exploits a flaw in the Linux kernel that Android uses... McAfee is detecting it because of it's malicious code.  You're fine to download it! :)

Thanks everyone for offering advice. I had one more question, I saw on the LifeHacker site that towelroot does not work on Motorola phones, is that correct? My phone is definitely a Motorola device. Thanks again!

It works, I've used it on my girlfriend's Moto M...  I don't know why they'd say it doesn't...

I downloaded the app and run it however it keeps saying towelroot isnt responding, what do i do?

Automate input into app
Is there a way to create a script or "app" to automatically input data into an already installed app.
I.e Fill and submit a todo task in a todo app.
Or fill a register form ?

In every device, there is a binary called input.
You can invoke it with from your application or even from adb:
$ adb shell input
Usage: input [<source>] <command> [<arg>...]
The sources are:
      mouse
      keyboard
      joystick
      touchnavigation
      touchpad
      trackball
      stylus
      dpad
      touchscreen
      gamepad

The commands and default sources are:
      text <string> (Default: touchscreen)
      keyevent [--longpress] <key code number or name> ... (Default: keyboard)
      tap <x> <y> (Default: touchscreen)
      swipe <x1> <y1> <x2> <y2> [duration(ms)] (Default: touchscreen)
      press (Default: trackball)
      roll <dx> <dy> (Default: trackball)

You can then navigate int the app using KeyEvent, click buttons, submit text to the focused element, etc.

Can Cyanogenmod 11 themes be used on CM 10?
In the past, I unintentionally discovered that Cyanogenmod 9 can use CM 10 themes.
While the play store shows CM 11 themes as incompatible on CM 10, would the themes work if installed manually?

The new Theme Engine, introduced with CyanogenMod 11 and later adopted by other KitKat custom ROMs, uses a different but simpler structure from past engines.
The theme files are all under the assets folder of CM11 theme APKs, while it was solely up to the developer as to where to put the theme files in the old Theme Engine themes.
While I have seen that there are some backwards-compatible themes available, they generally specify the target CM versions in the Play Store app listings. So if Play Store tells you that your device is incompatible, better heed the warning; but if you see in the app description / reviews that people using CM < 11 can install the theme, then maybe you can install the theme manually.
TL;DR
Try to see if people using CM < 11 have successfully used the theme. If so, then go ahead!

Allow USB debug pop-up not showing while installing CyanogenMod on Galaxy S3 i9300
I'm trying to install CyanogenMod on my Samsung Galaxy S3 (i9300, international). Had no problems, until I had to switch to the pc installer.
I'm stuck on the screenshot underneath:

I have enabled USB debugging on my device (since the day I got it), did all the stuff asked up until now, but I can't continue here. It doesn't show any pop-up on the device, USB debugging is enabled.
Can anybody help me?
Much appreciated!

The solution to my problem was simply revoking all authorisations granted to computers already. After rebooting both my Galaxy S3 and my laptop, the pop-up appeared again and I could continue the installation of CyanogenMod, which has now succesfully completed.

I also got the same issue in my lenovo mobile. Initially I thought the issue is with my mobile.
But actually the issue is the adb don't have enough permission to read the rsa key to communicate with the device. When we run adb server it'll create a folder named .android(Linux - /home/--username--/.android, Windows - C:/Users/--username--/.android) in the home directory of the current user which contains the adb rsa key files used to communicate between the devices. When I check the folder is assigned with root permission(I am using Ubuntu 16.04 and I don't know how its assigned).
So I deleted the folder using below command. Use the particular method to delete the folder based on your operating system. Below I mentioned for linux.

sudo rm -rf .android

Then restarted the adb server using below command.

adb start-server

Now It created the .android folder with the current user permission. Once done this I got the Allow USB debugging dialog.
Hope it help someone.

Does android Support RAW image capturing?
I'd like to capture RAW images from my Droid Camera rather than those compressed jpg's, is there anyway to achieve this?

samsung tablet 2 charging
Why does my tablet show a red x in symbol of it battery? Itried to plug in to wall and it does it also. Is it charging when plugged into wall plug with red x  in battery symbol.i haave been powering down to charge

I have a similar problem with the Galaxy Tab 1. It means the charger is faulty and won't charge the tablet (or will charge it very slowly - which seems to be your case). Try squiggling it around a little bit until it charge, also consider buying a new Samsung tablet charger (the phone charger has a lower output, which is inadequate for a tablet), don't use the knock-off brands!.
If the red X is there even when it's not charging, then the battery is faulty, take it to the service center.

The problem is that your tablet needs to recognize your charger as a charger that can provide 2A.  But only a Samsung charger will provide the right signal.  Any other USB power source will limited to 0.5A.  The result is that you need to get an original charger from Samsung.
See more explanation in my answer at How much power does a Galaxy Tab 10.1 charger need to supply?.

i have 500mb available but can't install 2mb app!
i have 500mb available but can't install 2mb app!!!
it's so frustrating i tried uninstalling apps, clearing cache, deleting files ... nothing works.
Please help.

Please clarify your question, what app are you trying to install, what is 500MB? Amount of RAM? Free internal memory? Free external memory? What is your phone model?

500 mb is 500 millibit, that's half a bit, and it's insufficient for anything. You probably mean 500 MB (capital "B" is for bytes, lowercase "b" is bits).

Look like most people here are too young to remember how many things can be done with 500MB. The answer is simple: Google got evil, and want you to throw away your smartphone and buy a new, more expensive one. Now they are friends of the smartphone companies, that's all.

Normally Android will leave some space empty for own usage, normally by clearing cache or unistalling apps you should be able to install that app.
Here that isn't the case.
What I would try would be to get rid of some apps try clean master from tge google play store.
Worst case Factory data reset it or wipe the data off of it.

Light of Back button is not working on my Android mobile
I have Android Fly F45 S. From yesterday I am suddenly seeing that my Android mobile back button light is not working. The back button is working but the light is not lighting. I have never dropped it anywhere. Please solve this

Whether the other button (right - options?) is lighting?

Yes others two are  lighting except the back button (right button) is not lighting.

Do a factory reset of your device (Remember to take app and data backup before doing the reset).
If this doesn't solve the issue, it may be hardware issue (either LED gone bad or any physical damage happened).

Thanks so much KeshavaGN. Let's see  factory reset can solve that problem or not.

How to start Samsung SM-T210 via pc , without wi-fi but with ethernet?
My home ethernet , is wired only !  How i can start and connect my tablet , through my pc ?

Some Android devices with USB-on-the-go (or USB host mode) support can use a USB ethernet adapter, when connected through a USB-on-the-go connector. If your device supports this, you can buy a USB ethernet adapter and connect it to your network that way.
If your device doesn't support that, you can use reverse-tethering to connect your device through USB to your PC's network connection (the PC acts like a router). See the existing questions with this tag to learn more about that.

Left Alt on External Keyboard Helper for use on JuiceSSH and Finch
I like to use JuiceSSH to connect a remote machine which is running Finch.
Finch uses Alt as its hotkeys prefix, for example Alt+n to go to the next window.
I have an external Bluetooth keyboard which has a left Alt key and a right AltGr key. The AltGr key is working fine, my problem is with the left key. The only configuration I found in the Custom Keymapping is to put left Alt as left Alt modifier. But that's not what I want, I don't want left Alt to be a modifier, I want the application to receive left Alt as it is, so that I can use shortcuts like Alt + n, instead of getting the char ñ.
Basically, I want to be able to control Finch using the left Alt as the shortcut prefix.

Galaxy S4 Calendar settings not saving
I prefer Google Calendar over Samsung's built in calendar app on the S4, for notifications. I don't need to remove the latter, and can't seem to; I just don't want it to display notifications. So I change the relevant settings, but periodically they revert.
I completely turn off notifications in S Calendar (no tone, no vibration), and turn them on in Google Calendar (with a specific sound and vibration and popup notification). In Google Calendar I also turn on "Show week number" and set "Week starts on" to Monday.
After some testing it seems these settings stay in place for as long as the device remains on. After turning it off and back on again, all of the settings in both S Calendar and Google Calendar, including the ones I mentioned not related to notifications, have reverted to their defaults (with notifications ON from S Calendar and OFF from Google) with the exception of the tone that I set for Google.
I'm fairly sure that having my phone turned off and then on again is exactly what happened each previous time I've noticed that my settings reverted.
I've looked at this post, and none of those solutions (for non-rooted phones) work; the settings still get reverted when I change them, and Samsung's calendar can't be turned off in Application Manager. If both calendars are having this issue I'm not even sure removing S Calendar would fix it.
A commenter on the first answer there seems to have the same issue, apparently since a recent upgrade. That may be the case for me too, because I bought this phone a year ago, but now both the device info and the app info for S Calendar have Android 4.4.
Why would these settings be reverting on every restart? How can I fix this, besides just not turning my phone off?

Modify shorcut or executable?
My car is a Chevrolet, and uses the Mylink radio system. It basically comes with some shortcuts (fixed) to run certain (limited) apps on an Android phone and show the phone's screen on the stereo car screen.
I want to run any app of the phone in the car screen.
So, my question is:
Is it possible to change the executable or shortcut on the phone to run another app?
For instance, my car can call an app called Bringgo. Can I change on the phone the shortcut or executable name to run Google maps instead Bringgo? So, If I tap the Bringgo icon on the phone, Google maps should run.
I think should be something like a symlink in Linux.
I have a rooted s3 mini, with CM 11.

What made the first Command fail?
I decided to clear my data usage stats on my Android in Settings > Data Usage from the terminal emulator app, but the first command came back with the error "No such file or directory".
The first command: rm /data/system/netstats/*
The same command that worked: rm /data/system/netstats/*
Here's a screenshot of what happened.

I'm running the supernexus custom ROM on android 4.4.2 on my Samsung Galaxy S3-19300
I was sure of the directory to clear of the stats but had to try a different directory in the latter commands, and the same command worked fine in the last line, what could've caused this?

Hard to tell for sure without "direct access", but here are the most likely answers:

there are no files in that directory, so nothing to remove
you cannot use rm to remove directories (that's what rmdir is for)
that will most likely fail as well, since /system is usually mounted read-only ;)
the original command succeeded at last: most likely some file was created there in the meantime.
