Bricked (Hard?) Android I5510 recovery
I was attempting to install ClockworkMod and CynogenMod10 for my phone using odin.
I followed the steps listed here
http://nguyenkieuhung1984.blogspot.in/2012/02/odin-how-to-upgrade-samsung-galaxy-551_01.html
And used 5.0.2.6_CWM_recovery_Gingerbread_willing.tar
(Admittedly this was stupid since my phone was running froyo, But I wasn't able to find the froyo build for this, the links are all dead.)
And now I think I'm hard-bricked. Neither adb, nor odin, nor Linux can see/recognize the device.
I've already tried a list of things
 - power+home+Volume-up (Nothing happens, flashes at the samsung screen and stays there)
 - Power+W (Takes me to little kernel mode, still no detection by any of the tools)
 - Power+T (same result as power+Home+Vol-up)
 - Power+Q (")
 - Power+A (")
Any Idea what can be done here?
I'm absolutely running out of ideas about what to do.
Any help is appreciated.

If you can't access neither recovery mode nor download mode then you won't be able to recover the phone.

No recovery is possible in anyway?

Take it to a shop that can actually recover your handset via JTAG.

@t0mm13b I've taken it to the official Samsung store and they said they can't do it and will have to replace the motherboard. (I guess they can't flash their motherboards).
I read about JTAG but I don't know of a shop in my area (or even state/country) that can do this. :/

Google around on ebay or somewhere - it may need to be posted abroad to get it JTAG'ged to revive it. No can do!

I'm not sure if it's worth that much effort, the motherboard will be replaced for ~60$ my phone originally costs ~180$ , I think shipping costs will amount to more than a motherboard replacement.

turn it off and then, when you are turning it on press power + q in same time.

Please read the question again. I've already stated that it has no effect.

Odin, firmware, no battery no usb cord, put the battery on, power+e for 10 seconds, connect to pc, and odin maybe will recognize it.

Vibration- Samsung Galaxy Ace
Can anyone guide me or advise on how to disable the in-built vibration for holding down on the screen whilst copy/paste to the clipboard?
Have searched in Settings and cannot find it.

I've checked the settings in my devices as I knew I've seen it somewhere.

On my Tabbies with 4.1.1: nothing found.
My Wildfire with 4.0.4 running CyanogenMod 9.1 has it in the Audio/Tone menu as Vibrate on touch
my Milestone 2 (CM7.2/Gingerbread) has it at the same place as haptic feedback
LG Optimus 4X (aka LG-P880) running stock 4.0.3: Again same place, Vibrate on touch

So the location of this setting seems to be quite clear -- but some manufacturers seem to have the setting removed/hidden. If your device belongs to that group, take a look at Spare Parts Plus! (no ads), which offers this setting at the end of its main screen as haptic feedback (the app is free and has no ads).

On my Galaxy S3, the Haptic Feedback (Vibrate when soft keys are pressed and on certain UI interactions) is part of the Sound Settings. I never have them on, but to test for this question, turned it on, and performed a copy/paste operation to encounter what you felt. It was successful, so undo it by going to sound, and disabling Haptic Feedback.

If you dwn load the nq smart booster app when using the app to optimize the battery ,the haptic appears and u can enable or disable it accordingly, its does not appear in d settings.

Would you mind to use proper english and could you include a link to that app?

How to charge a new Samsung Galaxy tab & what to expect
I am now trying to charge my new Samsung Galaxy tab since morning and it keeps flashing on me.  No signs of it being charged.  I am unable to switch it on.  Please, for how long is it going to have to be charged before I can turn it on for my usage?

you are chargering via the devices usb port and plugging it into a mains socket yes?

I realize that this is too late to help the OP, who apparently couldn't be bothered to follow up, but for future readers that might come across this in a search...
Samsung products are pretty picky about the chargers they will recognize, and there can be several problems using "known-good" chargers.
Most after-market chargers are designed for Apple devices, and will not quick charge most Android devices without a special cable or adapter. But even with this special charging adapter/cable, some chargers won't work for Samsung even though they might work for, say, LG (I have this scenario, so I know about it).
Also, most USB ports, and many chargers, cannot supply more than .5 amps, which is not enough for many phones or tablets.
So, the bottom line is to always keep the original charger and cable to test the device, and if you can, try to get a replacement before you need it, so you can compare it to the original to make sure it works.  Otherwise, if your original goes bad, and you get a replacement that doesn't work also, you'll never know where the problem lies.

Android to iPhone - clickable phone numbers in SMS messages
Need a way to have clickable phone numbers from iPhone SMS's.
I started a new job with a company that uses iPhones, and we can send phone numbers that can just be tapped to be called. When that same SMS comes to my Android the phone number comes through as some download that I can't just click on to make the call back.
Does anyone know of a way that will allow for this "clickability" feature for the Android? (from an iPhone SMS sent to me). I looked at Handcent, and GoSMS already but they can't do it properly.
Any suggestions would be most appreciated.

Could you possibly post a screenshot of what the SMS messages look like? Phone numbers should be clickable in android by default.

Restore colors after Android update
I bought an Xperia t two weeks ago.
When I plugged it today, I've been asked to update Android, what I did..
Now the sms "chat" changed color and display format.. many other things changed color and format too.
How can I put it back like it was before? I tryed changing the theme, it didn't work.
Is it a change from Android or is it a configuration problem?
Does android always change colors and everything? Everything had a dark/black background before, it's now all white, blue and purple...... I liked it dark
Thank you!

Which was your previously version and which is your new version?

This is because you probably moved to 4.X from lower. Welcome to Holo UI

I'm now on 4.1.2, I don't know where to see which one I upgaded from

Contacts and calendar no longer syncing between google and phone
I have a Samsung Galaxy S2 that has suddenly stopped being able to sync my calendars and contacts with GMail. Every time I try, I get the message sync is currently experiencing problems. It will be back shortly.
The only thing I've tried to do is to remove and then re-instate my account, but still no joy. Has anyone had this problem before? What have I done or am I doing wrong?
I don't think it's anything new that I've installed because it was syncing fine up till about a month ago, and that's long after I installed non-native apps such as Go contacts.

Just experienced the same on SGS2 running JB. Calendar hadn't sync'ed in 5 days, contacts hadn't in more than a week. Found out because I was looking for events I knew I had added - no warnings or anything :-(

Try these things:

Go to the tablet's System Settings/Account (Google), tap your account name, make sure Calendar is checked for sync.
Go to the Calendar app's Settings, tap your account name, and make sure the calendars that you want synced are checked.

OR
Settings-->Apps--> click on the ALL tab-->Calendar.
Then Clear Data.
Then go back to Settings-->Accounts-->Google--> Tap on Calender for sync.
Short cut name will change according to which android version you are using.

On my SGS2 running JB, I solved it by clearing "Calendar Storage" and "Contacts Storage". Thanks for the hint.

Go to the tablet's System Settings/Account.
Set automatic sync.
Go to Google account.
Check sync people details.
Check sync app details.
Check sync calendar.

Error while restoring data using ClockWorkMode recovery in Micromax a110
So I decided to restore but I got an error

  Unable to copy file ./dalvik-cache/system@framework@core-junit.jar@classes.dex

What seems to be the problem?

Have you kept all the blobs under clockworkmod/. The real content of files to restore seems to reside there (deduplicated between different versions of the backup), and I got such an error when I didn't put all the blobs from the time I made the backup into place.

Using a VPS as a proxy
I am trying to use my VPS running Cent OS as a proxy via SSH from my Galaxy S3 running Cyanogen Mod 9.
I can connect to my VPS using ConnectBot. In this program I sett the Port Forward to:
Type: Local
Source port: 8080
Destination: localhost:80
I am using Firefox browser with the Proxy Mobile 0.0.10 add-on. In those options I change all the hosts to localhost and proxy ports to 8080.
When I try any web address they all redirect to the default Apache 2 screen on my VPS instead of passing the traffic through from the web.
What do I need to change? Is there something in my SSH settings I need to fix? Is it something on my phone? I know the proxy works as I can get it running via Firefox on my desktop.
Many thanks.

Do you have the proxy running on port 8080 or 80? Try changing the Port Forwarding to use the destination localhost:8080.

How can I stream audio from another device via Bluetooth?

Related question: How can I stream music/audio from Android and PC to Android device via WiFi?

I would like to stream audio from a Bluetooth-enabled "dumb phone" to my Andoid phone. The Android phone is running Ice Cream Sandwich (4.0.4). I have searched the Play store for such an app, but all I could find were applications that did the opposite (stream audio from the Android phone instead of to it).
Is this somehow possible?

George, please note that questions like is there an app for X are off topic here (see our [FAQ] for details). I took the freedom to slightly re-phrase it to prevent it from being closed. Your problem is not "to find an app", but "to stream audio", right? :)

Hello, Can you please help me regarding this same ? Any example code ? I cant find any tutorial to stream audio. http://stackoverflow.com/questions/16789394/how-to-stream-audio-from-one-android-device-to-another-android-device-via-blueto

The Advanced Audio Distribution Profile (A2DP) is a source/sink configuration. In an normal scenario, you have a source (for example, and Android phone) and a sink (Bluetooth headset/speakers). But in your case, the Android phone would have to act as a sink to the dumbphone source. This is not currently supported, even though the phone supports the A2DP profile.
One solution would be to install a custom Bluetooth stack, which defines which profiles are supported on the device. This would additionally require a software component that can bypass the Android Framework and use the stack directly, since the framework lacks A2DP sink support. So far, no such modifications can be found.

I'm guessing such a modification would also require rooting the device?

At the very least, probably even flashing a custom kernel/ROM.

Connect Samsung galaxy tab to projector
I have Samsung Galaxy tab P3100 tab. I want to connect it to Projector for presentation. I searched a lot but din't get any solution. Does any one knows is it possible to connect it to projector? If yes then what accessories I need and what's the procedure?

That very much depends on the projector. Do your tab and the projector have a HDMI port? That would be my first check. I guess you don't want to carry another "intermediary" device around, and thus are looking for a direct connection, right?

I cannot find any specific accessories on the official samsung product page. However a TV-OUT Cable exists which presumable (if the projector has all the necessary inputs) can also be used to show the picture from the tab on the projector:
Product Name: Samsung ECC1TP0BBEGSTA Galaxy Tab TV Out Cable
Unfortunately the cable doesn't offer hdmi - output: only RCA Video.
An HDMI Adapter for the Galaxy TAB Series exists but it's not compatible with your specific model (Galaxy TAB 2 7.0) see the following product page

The Galaxy Tab 2 7.0 P3100 has no capability to connect to an external display.  The necessary hardware was not included in that model.
source : http://forum.xda-developers.com/showpost.php?p=37032295&postcount=110

You need to use a special adapter for that.  You need this:
Samsung P4 P5 HDTV Adapter for Samsung Galaxy Tab 10.1, Galaxy Tab 8.9, Galaxy Tab 7.7 and Galaxy Tab 7.0 Plus
SANOXY® Black HDMI Input to VGA Adapter Converter For PC / Laptop
6FT SVGA VGA Monitor MM Male To Male Extension Cable 80
If the projector has an HDMI slot then you don't need the HDMI to VGA and the VGA to VGA,  You just need to use the Samsung EPL-3PHPBEGXAR Galaxy Tab HDTV Adapter and then an HDMI cable.

Add user (personal) dictionary to Android stock keyboard for unsupported languages
I am sure many people have noticed that in the stock keyboard (Android 4.2 in my case) has more language layouts than it supports predicting. For many languages a dictionary / corpus is missing.
So since it is rather easy to build a corpus, I wanted to add my own dictionary for some languages which have no official dictionary. But I cannot find any solution. Has this been achieved before?
Note: Adding the words 1 by 1 is not a solution. :-)
If there was a solution, many people would be helped I guess. Thanks for any help and hint given!

HTC Cha Cha hard reset - stored phone numbers
My HTC Cha Cha won't turn on, so I want to hard reset it to factory settings. Is there a possibility of losing contacts stored on the phone? (They are very important to me).

You need to differentiate between a "hard reset" (hover the mouse over that tag: a forced reboot/shutdown by removing power (take out the battery, usually)) and a "factory reset" (again, mouse-over: A factory reset results in a full reset of an Android device to the original settings of the currently-installed ROM.).

hard-reset: here it's unlikely (though not absolutely impossible) to lose your stored contacts
factory-reset: here it's very sure they are deleted, as all data and all user-installed apps are deleted from the device

However, you can make a backup of your contacts. In the contacts app itself, when pressing the menu key, you should find a menu item for "export/import". Select to "export", and have it save the data to your SDCard. To be absolutely safe, before doing a factory reset copy all the SDCard's contents to e.g. your PC. After the factory-reset, you can use the very same item in the contacts app to re-import the data.
Btw: contacts export uses a common file format, which is understood by many other programs as well (*.vcf which means VCard File). It can be read e.g. by GMail (even the Web interface) or Outlook as well.
If you have your contacts synced with Google, they should be restored automatically once you configured your Google account on the device after the factory reset.

Um I think in Android hard-rest and factory-reset are synonymous

That's like with "virus" and "malware" I guess. Some use one word for all, some distinguish. And as "malware" is not necessarily a virus, a "hard-reset" not necessarily refers to a "factory-reset" -- which is why we have two separate tags (otherwise one of them would be a synonym, and you couldn't select both for the same question ;) Hint: look at "hard-reset" as opposed to "soft-reset"; the latter is used for a clean shutdown of the device using "hardware keys" if the power menu is no longer reachable (which might happen in a force-close-loop).

how to measure the RSSI strength signal between peers using wifi direct?
there is no feature to measure the RSSI between peers in Wifi-direct, so how to get RSSI between them.
actually i go under API for WIFI to see how they measure WIFI RSSI So i see that they send Command as parameter to native method, but i can't catch this command!!!
in this method wifi_send_command in wifi.c from this link.
as i know Android is under linux, the iwconfig is linux command to get the wireless information interface, if i used it can i get the Wifi direct information ? or it is just return the access points network information?
anyone have any idea about this ?

You can get this information inside wpa_cli. Open wpa_cli in wifi-direct interface and do a scan and scan_results as below.
adb shell wpa_cli -i<wifi-direct interface name> -p<socket path> scan
adb shell wpa_cli -i<wifi-direct interface name> -p<socket path> scan_results

You will get small info about connected peer(device address, channel,rssi etc). Hope this works!

Comments are not for extended discussion; this conversation has been moved to chat.

If you want to measure the RSSI between 2 peers before connection, just try:

In linux under wpa_supplicant
sudo wpa_cli p2p_peer 74:da:3f:58:5c:f0

(where 74:da:3f:58:5c:f0 is the MAC address of the second peer.)
In Android, it should be something like this (guessed and untested)
adb shell wpa_cli -i <wifi-direct interface name> -p <socket path> p2p_peer 74:da:3f:58:5c:f0

After that you will get a big string. Then search for the word Level (the RSSI comes in dBm).

For non-rooted devices try the following:
Device A: Linux
Device B: Android

Get the P2P group name of one device. This can be seen by using wpa_cli on the linux device.
<3>P2P-GROUP-STARTED p2p-wlan0-0 GO ssid="DIRECT-Gw" freq=2462 passphrase="Vz4GVojX" go_dev_addr=02:04:4b:e0:80:73

Open an adb shell to the Android device.

Type:  dumpsys | grep "DIRECT-Gw"

Look at the output:

 - SSID: DIRECT-Gw, BSSID: 02:04:4b:e0:00:73, capabilities: [WPA2-PSK-CCMP][RSN-PSK-CCMP][ESS][WPS], level: -61, frequency: 2462, timestamp: 104993415063, distance: ?(cm), distanceSd: ?(cm), passpoint: no, ChannelBandwidth: 0, cen

HTC Cha Cha - wont start
I have problem with my HTC Cha Cha.
After trying to start I see welcome screen, then black screen and sound signal, then welcome screen... and in infinite loop, I have to take out battery to stop it.
Any suggestions what to do? I can plug it with USB cable to computer and try to perform some actions, but I have no experience in fixing Android.

What where you doing with the device before it started doing this? i.e what trigged it to get suck in a bootloop

I don't know, is this actual cause, but I plugged discharged phone to charger and second after that I tried tu turn it on. After that I have this problem.

If it was completely discharged and dead I suggest plugging it into a mains socket for a good couple of hours then try again

@ZacPowell I have tried to charge it from yesterday, also removing battery for few minutes.

Switch to another keyboard language using stock keyboard
I have an Xperia (SOL21).
How can I fast switch to another keyboard language, using the default keyboard?
I'm mostly typing in Japanese, but usually swiftly change to Swedish and English (on a non-Android device). How do I do it on Android?

Which Android version does your phone run?

It is Android version 4.0.4.

I got another Android too, a Galaxy SIII, at 4.0.4. I'm unable to do the same thing there as well. It seems like the only languages available are English, Japanese and Korean. Did the makers (Sony and Samsung) deliberately remove all other keyboard languages? I assume Android should support most keyboard languages by default.

I opened another question regarding default keyboards, as it seems that the devices I have don't have the default keyboards. http://android.stackexchange.com/questions/40881/install-default-android-keyboard Other answers around here all assume the default keyboard is there.

I would recommend leaving the stock keyboard and using the Google Keyboard. It does  have a language change key that is great for changing inputs, unlike some stock keyboards. I've set up English (QWERTY), English (DVORAK), and Spanish. Its compatible with Android 4.0+.

This doesn't really answer the question. That's not to say you are wrong, but some people (like me) came here because they are trying to leave the stock keyboard, but fail, because they need to change their language (to English) to enter their wifi password and install another keyboard.

I'd refute your "observation" by noting that OP has said nothing about not being able to access their wifi to install another keyboard app. You can also sideload apps, even without root. Wifi is not strictly a requirement to have new apps installed. OP is only asking for a quick way of switching between keyboards.

To switch to another language, you need to open the keyboard selection menu, where every language will be listed as an individual keyboard (named Android keyboard). This menu is in the notification area (just as another notification, present when the keyboard is visible).

How to move system programs to sd card?
System programs like youtube, gmail and maps are consuming over 50 MB of my HTC Explorer (v2.3) which is a rather low end android phone and has only 128 MB of system memory.
As a result the low memory notification is kind of consistently visible. Can I (how) safely move them to the sd card?
EDIT: My device is rooted.

As @Cyborgz said, you have to first root the system. Take a look at this question to see your device is listed. Even if not, probably your device's closest like HTC Hero for more information.
Once rooted you have to partition your SD card to create a SD-Ext partition. See the question "SD card partitioning? Why? How?" to know how.
Then you can use apps like Link2SD to move few user applications to SD card and create link of few user applications to the sd-ext partition. By this way you would have created loads of free memory in your device. If you still want to get more like moving YouTube, GMail and Maps, you can use Link2SD to first convert them to user app (from system app) and move or link them (most likely moving will not be permitted).

my device is already rooted.

In Order to access the System folder Root access is required. All Systems apps are available in /system/apps folder, if you have root access, just choose the required app and move it SD Card with the help of file manager.
If you would like to move your system data partition i.e., System/Data you can try This
Hope it helps.
PS: Please do a research before doing any thing in system folder, if you mess up, then i am not responsible!!!

Not all apps can be moved to SDCard, some are required to be on /system/apps partition...

/system partition has no effect on the "low memory" notification. It's rather the updates to system apps (those are not stored on /system but rather in /data) which are the crucial point here. Not sure if those can be moved to SD.

There is an alternate approach without root device. By using sdk tool to set install location as sd card, you can move most. It is a good middle of the round solution.
See url - http://techgage.com/article/moving_your_non-movable_android_apps_to_an_sd_card/

Are you sure that works for pre-installed apps? As they are installed in /system, they cannot be moved without root access. Maybe their updates could, however.

Stop Facebook using GPS
I have set location to off but I can see it is still trying to use GPS from the icon in the top left corner.
Where in the settings can I switch this off for Facebook only? Despite Messenger location servvices being set to Off, everytime I open the app it tries to get a GPS lock.
I am running the latest stock Nexus 4 firmware and Android 4.2.

Are you sure it's facebook app? What happens when you remove it?

AFAIK, the location services option in FB settings is for "Facebook Messenger" only. The GPS notification appears for me whenever I go to pick a location, or "Check in", regardless of whether I have "Messenger location services" enabled or disabled in FB settings. But otherwise the GPS notification does not seem to appear for me (Nexus 4, FB 2.2.1).

Go into Settings > Location Access, Look for Location Sources, uncheck GPS Satellites and Wifi&Mobile network location.

@t0mm13b: But won't this disable location services for the entire phone?

@w3d Yes and the OP asked "Where in the settings can I switch this off?" despite having it turned off from within Facebook app... just saying :)

@w3d As soon as I open the application, the GPS tries to get a lock.

@t0mm13b Sorry I will rephrase, I want this off for Facebook only.

Are you rooted?

The only thing I can think off is to selectively disable the GPS/Request Location permissions in the app itself - think CM has that feature...

Is it possible that a "Facebook App" (installed in FB itself) is requesting location services?

Unfortunately, there's no way to do this in the app settings. You can turn it off for messaging, and you can always turn off the alerts for "friends that are nearby", but the check-in functionality needs to call the GPS. And let's not forget that they are working toward creating targeted ads, which in many cases require knowing (approximately) where you are.

AFAIK PDroid is the best solution. (Except you need to be rooted) You could even set a custom GPS location per app.
Permission Explorer is a good alternative.

How can I control one android device with another android device?
How can I use android device A to view and interact with android device B? I want total control not just accessing the file system our certain features. VNC maybe?

You already tagged your question VNC -- so give it a try :) Yes, that would be a possibility -- but most likely will require you to root your device. I added the remote-control tag to your question: just follow it, there will certainly be similar questions with answers to get you started. Yupp: Remote connection between two android devices

Yes I could just experiment and try and figure it out myself our I could post a question on a Q&A site so I hopefully don't have to reinvent the wheel.

Matt, you could check the places I've mentioned to see if there's something already answering your question. The link I posted in my previous comment looks like it is the same stuff you are looking for. If that does not answer your question, you can simply update your above post indicating you checked that and giving the reasons why your question is different. I was not complaining, but hinting to possible solutions ;)

Stopping an app from hijacking browser downloads
I have an app (EBookDroid) that automatically opens all PDF links instead of letting me download them. Is there any way to stop this without uninstalling the app?
I'm on unrooted Android 4.2 and using Chrome as my browser.
Note that EBookDroid has no defaults set. If I open a PDF with a file manager then I'm given the option to choose an app to open it with.

Since EbookDroid is open source, I took a quick glance at the AndroidManifest.xml, the pertinent information is this part, between lines 24 and 33:
<intent-filter>
            <action android:name="android.intent.action.VIEW"/>
            <category android:name="android.intent.category.DEFAULT"/>
            <category android:name="android.intent.category.BROWSABLE"/>
            <data android:host="*"/>
            <data android:scheme="file" />
            <data android:scheme="smb" />
            <data android:scheme="content" />
            <data android:scheme="http" />
            <data android:scheme="https" />
.... SNIP ....

The keyword(s) is in the Intent Filter's category

android.intent.category.BROWSABLE
and the android:scheme="http"

With both of these, the app "listens" on the http/https both web, plain and secure and among others such as smb for samba file shares, etc, for the content links that contains the pdf, djvu and others, identified by the lines between 35 and 43:
<data android:pathPattern=".*\\.pdf" />
<data android:pathPattern=".*\\.djvu" />
<data android:pathPattern=".*\\.djv" />
<data android:pathPattern=".*\\.xps" />
<data android:pathPattern=".*\\.oxps" />
<data android:pathPattern=".*\\.cbz" />
<data android:pathPattern=".*\\.cbr" />
<data android:pathPattern=".*\\.fb2" />
<data android:pathPattern=".*\\.fb2\\.zip" />

This will explain why the app hijacks any browser downloads and thusly

that automatically opens all PDF links instead of letting me download
  them

Why not post an issue on the same site to let the developer know about this?

I had the same problem, but found out that disabling handle http in the ebookdroid settings fixes the issue.

How do you disable message preview in the Android 4.0.x stock email app?
How do you disable message preview in the Android 4.0.x stock email app?  The only message preview options are "Small", "Medium" and "Large".
(Android 4.0.4 on a Droid Bionic.)

Its unlikely there is a way to do this if there isn't an option to disable it.  You would have to use a client that does offer the option to disable message preview if you wanted to disable message preview.

@Ramhound - Well that stinks.  If you put this as an answer I will select it as best answer, because my gut says you are right.

Unknown email address showing in a contact card
I have a contacts issue. My wife, lets call her Jane Doe for example, is showing an unknown email address in her contact card on my Android phone. It shows her actual address then a second bogus one.
Jane.Doe@gmail.com which is correct but then a second one shows as JaneDoe@gmail.com and this email address has never existed.
This bogus email address doesn't show in my Gmail contacts under her name on the web browser interface and also she has a Google+ acount again with only the correct email address showing.
It only shows up in my Android phone and if I edit contact, i.e. edit the contact info stored on my phone the bogus email address disappears and cannot be edited suggesting its pulled in from another source.
The Android contact links consist of only the local (synced) Google contact, the Google+ contact and the Whatsapp contact that only contains the name and mobile number info.

Dots are ignored in Gmail addresses. jane.doe@gmail.com is the same as janedoe@gmail.com is the same as j.a.n.e.d.o.e@gmail.com.

Optimize TeamViewer for android bandwidth consumption
I am using TeamViewer for Android to remotely control my computer and it works great, but I recently noticed it uses up a LOT of bandwidth, even in Optimize Speed mode. I have a limited 3G plan and I would like to reduce TeamViewer's bandwidth consumption as much as possible, at the expense of image quality. For example, I would have no problem with going to grayscale, or 256-color mode, but this option is not available on the android client, as far as I can tell.
Is there any way to optimize the bandwidth consumption of TeamViewer for Android, beyond choosing the Optimize Speed quality setting? If not, is there any other remote desktop client for android that you can recommend which does a better job that TeamViewer in this category?
Thanks

Give Chrome Remote Desktop this a try. The recent version claims "Reduced network usage when running in the background."

I use Teamviewer and love it.  Before Teamviewer I used several of the pocket VNC versions you can find for Android.  Some of those version have grayscale options.  The drawback is you will have to forward a port on your router to get VNC to go through.  The other option you may look at is if the program or programs you are looking to control have a web API you can hit rather then the whole PC.  below are some links for the other programs to control your PC via ANDROID.
EDIT: thought about it a little more and remembered you can use LogMeIn Hamachi and VNC.  Set up the LogMeIn Hamachi client on the PC you want to connect to, then you can VNC into the Virtual IP the Hamachi client provides.  This will enable you to use the advanced display setting in some of the VNC clients.  Hamachi

Android Remotes
More Remotes
Some more

Thanks, but I forgot to mention in the first post: port forwarding is not an option for me, so it has to be a software that supports NAT bypass

Teamviewer is your best option, followed by LogMeIn.  I have also used the LogMeIn product and it works well.  Teamviewer has a better interface and ran cleaner in my opinion.

Note that the free LogMeIn Hamachi service has been 'discontinued' http://community.logmein.com/t5/LogMeIn-for-iOS/Free-Service-Discontinued/td-p/108649

ICS Wifi not blue and internet not working
I just bought a Phone here yesterday running with Android ICS, the first time I used the wifi was ok, no problem. But now, the wifi is not working sometimes even I have a strong wifi connection. My PC, and my phone are on the same network. My PC is reading Full signal strength, as I am literally 5 feet from the wireless router. My phone is showing NO blue. Wifi meter is grey even if I have excellent connection, If it is blue, I can use my internet, but when it is grey I can't use my internet. I have the blue wifi around 20% of the time. What should I do?

See also: What does it mean when the connectivity icons in the status bar go white/gray? -- though that does not explain why your Internet should be completely disabled. Only Google Services have no connection, while everything else should be fine.

Have you tried restarting everything (router, phone)? Are you sure your router has enough available IP address and doesn't have a QoS rule blocking access? Can you connect to any other WiFi network? Are you sure you're connecting to the correct SSID?

Exchange the phone for replacement.
Most likely defective wifi card in phone.

That's a pretty big leap without knowing if the OP has done any basic troubleshooting.

wifi not blue means net cannot connect with google server! if u have rooted ur device just go to etc>hosts.bak using root explorer just add a '#' before the ip at the bottom line. Hope this will resolve ur issue works 99% with evry1! or try that on the first line ip!

Android system apps deleted, restore to default condition.
I have rooted my android phone and removed some of system apps form my Samsung GT-S5360 in order to save space. These are

Email.apk
EmailWidget.apk
Memo.apk MyFiles.apk
QuickOffice.apk
SamsungApps.apk
SamsungWidget_ProgramMonitor.apk
SamsungWidget_StockClock.apk
YouTube.apk

My phone is working very good except when I tried to play "FM Radio" which is not detecting any station at all.
Please tell me how to rest this phone to buy day condition. Or if replacing/flashing the firmware to S5360DDLK2_S5360ODDLK1 will solve my problem. Will change my IMIE etc?

Usual recommendation though too late in your case (remember for next time then): Don't ever go straight to delete, but first freeze (disable) apps to check for possible side effects. Had you done so, a simple "unfreeze" would have restored factory conditions without losing any data.

First you should try to use the settings item "Reset Phone".
You can find it at settings->back up and reset -> factory data reset.
But remember: if you do this all your data will be deleted so do a backup on your pc or cloud first.

If this does not help try to find out your kernel and build and baseband. Normally Settings -> about phone.
Load your firmware from samfirmware and flash it with odin.
There are several guides you can find (one is at samfirmware too).

Maybe there is a solution without resetting or flashing, but I don't know any.
Hope it helps you.

Yes, you will have to reflash ROM to restore to purchase day settings.
Since you deleted those .apk files, a simple reset won't do the trick.
IMEI is hard coded in phone, reflashing firmware will have no affect on that.
However, I don't see how any of the apps you listed as deleted should have anything to do with FM radio reception.... maybe the samsungapps has the programming to make radio work?

Galaxy S2 turns off randomly

I got a problem with my Samsung Galaxy S2 I9100.
I have it for round about 8 monthts now and experimented with some custom roms. I installed cynogenmod 9, 10, 10.1 tested Syah Kernel and installed AOKP in DualBoot and so on.
Everything was fine until I installed CM10.1 as single boot.
There my phone started to turn off randomly and I thought that it would be a software mistake and reinstalled the Samsung stock rom. But the problem is still existing.
I dont use a firewall or antivirus program and did not checked up anything.
Can you help me with this issue or tell me how I should start detecting or solving the problem?
Thanks for your help!

Edit:
I installed awg Antivirus and scanned my phone. Beside SWFPlayer there was no app which is "dangerous". And my "marked" settings were "Enable Debugging", "Allow Third Party Apps".
Edit 2:
I now updated my phone via Kies to Android 4.1.2 but the problem still exists.

Edit 3:
I think I got the problem. I already wrote it in my last comment. The batterie infalted and I think  that's the problem. I ordered a new batterie and hope that's it. If not I don't know what it might be...

See our chat protocol -- it's not your phone, but CM10.1

I do not use CM 10.1 anymore. I reinstalled newest stock rom from Samsung.

Just to clearify: The problem started with CM10.1, but even persisted after you flashed to stock?

Yes thtat is correct!

Do you still use the dual boot kernel after flashing a stock rom? Try flashing the stock kernel also and check if it helps

When I flashed the stock rom I entered a recovery differing from the Siyah Recovery. So I think it is not installed anymore. But beside starting the recovery, I checked my Android information with one of my mates who never flashe dhis phone and the information are equal.

Do you use a battery saver app?  I have found that they cause random reboots and/or sleep of death with my GS2.

No I don't use something like that. Only AdAways, Firewall, AntiVir.

After I started the adb Logcat to find the reason for the shutdowns (and I did not find any) I removed the batterie. And than I noticed that it has inflated. So I think it is the batteire which is not working.

One device does not show on Google Play
I just purchased two identical Android tablet for my kids, running ICS 4.0, both using the same gmail account. I have the Google Play store installed on both of them, but only one of them show on my Devices list on Google Play. I could not find a way to make the second device show on the site.
As I said, they are using the same gmail account and sharing the same site-specific password (as I use two-factor authentication). What can I do to make the second device show on the Device list so I can send app to both of them?

Google two-step identification not working on my phone
I just turned on two-step identification on my Google account. It works fine on my desktop. It also works fine on my iPad with help of application-specific password.
But I have troubles with my HTC One X. Once I've turned two-step identification on, it immediately displayed a warning in notification area, that it cannot log in with Google account. Ok, when I click on it, I'm asked for a new password.
If I enter an application-specific password, I have an error - password is incorrect. If I enter my account password, it asks me to log in through browser then and redirects me into browser. Then I log in with the browser, I receive my confirmation code by sms, all works fine. Then I redirected back from the browser and have the same error!
I tried to visit https://accounts.google.com/DisplayUnlockCaptcha from my phone with no success. The only other options I saw on the Internet about my problem is to reset the phone settings. It's too hard, I'd like to try other solutions first.
Any ideas?

How to switch user profile based on password / lockscreen pattern
Currently, I have a family use tablet running on 4.2 Jellybean
Model is Ainol Novo7 Flame, a cheap Nexus7 alternative. Nexus7 is quite expensive in my country on its release so I bought this one instead.
The problem is that the tablet is shared. I already set-up multi-user profiles for each of us.

Family mode
My mode
My sister's mode

The default user set is family but I want it to automatically switch user-profiles based on the entered password or pattern lock.
example: password 1358 triggers My mode while entering 2467 triggers My sister's mode profile
I would also like to have an option to lock certain apps automatically when in family mode but unlocked in My mode
Is there a way to do this? or is there an app that can closely do some of it?

I wonder if some combination of Titanium Backup, Tasker, and Secure Settings would do the trick. I'm posting as a comment instead of an answer because this is an untested wild guess.

I havent used tasker yet. I might as well try it and see if it can mimic some actions. Thanks for suggesting.

Tasker cannot get the typed password, it only detects lockscreen state. Question still open for answers.

there is also a thread on XDA
http://forum.xda-developers.com/showthread.php?t=2363535 Link to feature request of cyano
https://jira.cyanogenmod.org/browse/CYAN-984

Yes, You can get these facility in all vivo model as per your requirenent, means mode of entry in to the phone is depend on given password or pettern lock,,, its happen only in vivo mobile,

I'm not sure automatic password detection is available. After all, computers don't really have that function. You still have to select the user/enter username.
As far as having the option to lock certain apps automatically when in family mode but unlocked in My mode, upgrade your Android version at least 4.3 (newest is Lollipop 5.0 but that's not available across all devices yet- 4.4.4 KitKat is widely available).
This will give you access to a new profile/user type: Restricted Profiles.
From Google's help pages:
About restricted profiles

As the tablet owner, you can create restricted profiles that limit the
  access that others have to features and content on your tablet. For
  example, you can create restricted profiles to prevent family members
  who may have access to your tablet from viewing mature content.
You can use restricted profiles for several purposes, including these:

Parental controls. Selectively restrict family members from accessing mature content.
Kiosk. Set up the tablet to demonstrate selected apps and features to customers.
Retail. Let customers explore tablet features, but prevent them from    browsing or playing games.
Point of sale. Limit employees to the use of selected sales and register apps.

To set up a restricted profile:

Note: You must be the tablet owner to create a restricted profile.

Touch Settings  > Users > Add user or profile.
Touch Restricted profile, and the new profile with a list of settings displays. To name the profile, touch New profile.
Using the ON/OFF toggles and Settings , select the features and settings you want to grant access to.

To set up the new profile, press the Power button to return to the
  lock screen, then touch the new profile icon.
When the restricted user finishes setting up, the Home screen is
  empty. The granted apps appear after the user touches the All Apps
  icon .
Edit a restricted profile
Note: You must be the tablet owner to edit a restricted profile.

Touch Settings  > Users.
Touch the profile icon.
Using the ON/OFF toggles and Settings , select the features and settings you want to grant or deny. The changes take place in real time.

Important: If you turn off an app, the profile user loses all content
  associated with that app. If you grant access again, the content isn’t
  restored.

SG3 not recognised by PC but recognised by laptop
Why won't my SG3 show up on my PC when connected with USB cable? It shows up on my laptop. I have looked at similar problems in forums but have not found a case where the phone IS recognised by other computers.
It used to work with my PC. I have no idea what changed. When I connect the phone with the USB cable, it makes the duhduh connecting sound. The phone charges and the display shows it connecting as a media device. On my PC, no device shows up. Naturally, I can no longer transfer files by USB. Very frustrating.
My operating system is Windows 7. Any help appreciated (for a not a very PC-savvy soul).

Did you install/update the drivers? Sometimes you have to update them via the Windows Update option. Or reinstall them. Sometimes that helps too.

Galaxy S2 does not see MP3 files in any player
I transferred several MP3 files to the Samsung Galaxy S2. But, the player does not see the MP3 files, only the DCT files. I installed several different players, and had the same result.
How do I fix the problem?

How did you transfer the files? Has the Media Scanner been running afterwards? See e.g.: Force Media Update?

also try to reset/reboot your phone. Sometimes, android does not properly mount the sdcard when it is unmounted from the computer. It will also run media scanner on startup.

How can I update the default stock browser (com.android.browser)?
I have version 2.3.3 of the stock android browser on my phone.  I know there are newer versions out that support features that I want which are not available in 2.3.3.  However, I do not see any upgrades available, and in fact the stock browser does not even show up in the Google Play store.
I figure I probably need to manually install from somewhere, but where do I find the necessary files and how do I perform the upgrade?  Note: I am not interested in upgrading to a newer version of Android.

Firefox mobile supports Android 2.2 and above is you're stuck with an older version of Android and needs features that aren't available in older browsers.

Check this XDA post. It has an APK for a 4.2 AOSP browser.
NOTE: Install at your own risk.

Thanks! There aren't really any install instructions... in searching my system I see data/data/com.android.browser and /system/app/Browser.apk.  I currently need the browser to replace what WebView is using, will it replace that too?

How can I send service commands from my Nexus 7?
I have a Nexus 7 3G and I often need to send network service commands (e.g., to use top-up codes or to activate/de-activate data-plans), but can't find a way to do it from the tablet. Instead I'm forced to take the SIM card out of the Nexus and put it into a mobile phone temporarily. Is there a way to do this directly from the Nexus 7?

Could you please clarify a little how you do that in a phone then? This might give us (at least me) a clue what exactly you are missing/needing. Are you talking about USSD codes? In this case, you might try to install some dialer app from the playstore (just a raw guess).

Sorry, I should have been more clear. Some carriers allow you to send 'service commands' to change some options in your subscription. With my current carrier, if I dial something like *139# on my cellphone, I can check my balance, while *100# allows me to perform other operations (incl. top-up).

I think USSD Checker is the app that you are looking for.
It allows you to send USSD codes to your network without the use of a dialer. I haven't tried it myself though so comment whether it works or not would help.

Thank you (can't vote up because of reputation). Strangely, none of these applications are compatible with my Nexus 7 3G...

It might be because the Telephony app is not installed by default. This is required to have SMS, Call functionality including sending USSD. You should try a custom ROM with telephony built-in and it should work.

Thanks, but that is not very helpful - I'd rather avoid having to resort to custom ROMs to get what is usually standard functionality.

Any terminal commands available that will check USSD response?

came across this, check if it helps.
......
i'm in indonesia, i use nexus 7 lte 2013,
first i do is unlocked n root it. then i install ussd dialer from play store...
voila.. its worked..
last thing i do is install xposed framework n xposed sms module..
no problemo with pre-paid card...
heheheheh

This needs more explanation.  How do you operate it after installing these things?

Is there a way to adjust the memory allocation to increase the allocation for apps?
I have an Mi Traveler Android model 10R2 tablet and I am continuously getting a "memory low" message. I have added a SD card and moved some apps to the card, but still get the same messages. In checking the storage area, it shows the allocation of memory as follows:

Total space 3.09GB
Apps 84.95MB
Downloads 116MB
Misc. 19.16MB
Available 2.87GB

Then under Apps, it shows the following:

Total space 252MB
Apps 204MB
Available 21.94MB

Is there a way to adjust the memory allocation to increase the allocation for apps?
It seems that I am only getting the low memory when apps are updating or new apps are being downloaded.

I don't know your tablet model. Does it feature an internal as well as an external SDCard? If so, can you please check how much space is free in "device internal" memory (as opposed to the "internal SD")? This is what causes that error in most cases, as soon as free space drops below ~25MB.

as it stands your internal memory is unable to increase. Adding a SD card will only increase space for music, pictures and some apps.
My assumptions are that your phone is a lower end affordable device. These are plagued with smaller memory, that are almost always maxed out right out of the box. Your solutions are limited to your device and the applications you install.
One solution would be to move as many apps to your SD card as possible. The problem lies with many apps not supporting this feature.
Second solution would be to run only the apps your phone came with and not update them. Of course this is not what a user would want, and is not recommended.
The last option would be to buy a new phone with internal space of at least 4GB to not run into this trouble, of course the more internal space the better.
Also note that alot of apps use more space because higher end phones have the ability to have them installed. This leaves lower end phones in trouble because they can no longer run the apps they use to.
Sorry to be bearer of bad news, I hope this information was of help.

The listed amounts are for the internal memory.

Would you know the answer to this: Is there a way to adjust the memory allocation to increase the allocation for apps?

You can't add more internal memory to the tablet, if that's what you mean.  Move some more apps to the SD card so that they don't take up space in the internal memory.

Whenever I try to download an app, it keeps wanting to download it to my old Android phone
I bought a used Coolpad, but like new. Whenever I try to download an app, be it an old one already installed on old phone or a new, never before loaded one, it keeps wanting to send data to old phone, an LG Admire. In the box, looking for device compatibility, only the old phones model number comes up.

Does the Coolpad have Google Play installed on it?

From where are you trying to download the app?

thanks for responding. I hope I'm doing this right, and this is where I'm supposed to respond to you. Yes, Goggle play store is loaded on phone and it can be any app. from any where. smart tools, angry birds any one of of them. When looking for device compatability, it always comes up that it is but always it's the admire. I'm clueless, Thanks again, there are still a few good people out there.

It is about Google Account I think. Logout and create a new account.

I'd do a factory reset, then log on as yourself and try again.  There should then be no trace of any other accounts on that device and you should be able to start afresh.

How to install a ROM with CWM when /data (and /sdcard) are encrypted and I can't reformat them?
I used to run CyanogenMod 9.1 with device encryption on my Galaxy S3, and decided today that I wanted to try a CM 10 nightly.
A problem with device encryption that I didn't know about before is that it's impossible to turn off. ClockworkMod Recovery (5.8.4.3) can't mount the /data partition (and, by extension, /sdcard). This means that I can't use CWM to factory reset or install a new update.zip, since the update.zip must lie on the internal sdcard.
Trying "choose zip from sdcard" gives "E:Can't mount /sdcard/" and choosing "apply /sdcard/update.zip" gives "E:Can't mount /sdcard/update.zip". This happens even if I've used adb to put the update.zip in the /sdcard mountpoint.
Factory resetting from CWM gives these two errors: "Error mounting /data!" and "Error mounting /sdcard/.android_secure!". Factory resetting from CM9 didn't work. I've since tried to flash CM10 with MobileOdin, which didn't work, and now I can only boot to CWM.
Does anyone have any idea about how I could mount /data or otherwise get a working ROM?
I've taken backups of everything. The tools I suppose could help me, but I haven't tried because I'm new at this and don't want to hard-brick my phone, are fastboot and heimdall.
TL;DR: S3 only boots to CWM, but CWM won't mount /data and so can't flash zips.

I fixed mine right now. Using Odin, load the original image of your phone from the exact provider in pda. Now, it's like brand new.
P.S. You have to unrar the image file, or Odin won't see it. After you unrar, it should have a MD5 file.

Thanks! I've never used Odin. Looks like a Windows program? I don't have access to a Windows computer =/

Have you tried to reboot to the bootloader? You can do so using adb reboot bootloader. From there, you can flash boot.img and system.img. Look at fastboot options.

How to root the LG Optimus 4X (LG-P880)?
I just got a brand new LG Optimus 4X. Feeling naked without the privacy protection offered by apps like LBE Privacy Guard, and missing good backup solutions like Titanium Backup (and no, Carbon Backup cannot really compete here), I want the device rooted.
How can that be achieved?

In fact, I never had an Android device where this was that easy to achive! Our friends at XDA-Developers offer a guide and the necessary tools in this thread. Having a "Microsoft free zone" and "only" running Linux machines (yeah, even the Android ones run a Linux kernel), I was able to follow up those steps with a little adaption here and there -- and so I will sum up the results for Windows and Linux users as well:
Preparation
First you need to download the required tools, all of them available at the linked XDA-Developers thread:

o4xr.zip is the rooting toolkit
IS11LG_SystemBackupTest.signed.apk to prepare your device
Windows users only: LGUnitedMobileDriver_Ver_3.7.2_LG-P880_LGO4XHD.zip -- the Windows drivers for the device

Having everything downloaded, some additional steps are necessary at your computer:

Windows users only: Unzip and install the drivers
Linux users: Make sure adb is able to detect the device (check with adb devices). If it's not, see at the end of this answer for some hints.
Everybody: Copy IS11LG_SystemBackupTest.signed.apk to your Optimus (e.g. after connecting it via USB in MTP mode, copy the file to the internal SDCard)
Everybody: Create a new directory, unzip o4xr.zip there, and change into this directory.

The rooting process

On your Optimus, go to Settings→Security and make sure "Unknown Sources" is TICKED (i.e. contains a checkmark)
Go to Settings→Developer Options and enable "USB Debugging"
Now install IS11LG_SystemBackupTest.signed.apk (e.g. use a file explorer to find and "launch" it)
Open the "SystemBackupTest" app you just installed. Nothing spectacular will happen, so don't be disappointed here.
Hold the power button and choose "Power off and restart".
When you can see the lock screen, you may notice that the phone is running very slowly, this is normal.
Once the device is fully started up again, connect it to your computer with an USB cable. Make sure the phone is in "Charging Only" mode.
On your PC, open a terminal (Linux) resp. command (cmd.exe, Windows) window and change into the directory you've extractedo4xr.zip` into.
(on Windows, you may need admin privileges: right click, run as administrator. On Linux it did fine for me without superuser/root permissions)
Now run the rooting script:

Windows users: type root followed by the enter key
Linux users: type ./root-linux.sh, also followed by the enter key
Any Mac users? Type ./root-mac.sh, also followed by the enter key. Don't worry, it won't root your Mac/Linux machine (Windows users: it is unlikely to root your box, either :)

DO NOT DISCONNECT YOUR PHONE WHILE THE SCRIPT RUNS! Wait while it does its job. During that process, the phone will reboot automatically a couple of times. The script will inform you about this in your command/terminal window. Once the command/shell prompt returns, the misdeed is accomplished :)
Now uninstall SystemBackupTest from your Optimus. Do not launch it again at this state, or you might have to start over from step 5 :)
On your phone, open up Google Play Store and search for "SuperSU". Update the app when prompted, then open it. Press OK to update the SU binary.

You now have root and can safely restore the "Unknown Sources" and "USB debugging" settings back to how you had them! Congratulations! Next steps are to install Titanium Backup, LBE Privacy Guard, and all the other things you might need and which require root!

Hint for Linux users to get adb recognize your Android device
These steps should work with all Android phones. The example data of course should exactly fit the LG Optimus P880 this question deals with.

open a terminal window, and make yourself root (sudo su -)
enter the following command: lsusb. Note the output in your mind.
connect your device with USB Debugging enabled using an USB cable.
again issue the lsusb command. Now it should output an additional line which has to be the just connected Android device. For the LG Optimus P880, this should read like:
Bus 002 Device 103: ID 1004:61a6 LG Electronics, Inc.
1004 is the vendor ID for LG, 61a6 the device ID of the P880 in USB Debugging mode.
use your favorite editor (still in root mode!) and open /etc/udev/rules.d/51-android.rules (if no such file exists, simply create it). Add the below lines (first line is optional), and then save the file.
restart the UDEV daemon: service udev restart

Now you just need to disconnect your device. When reconnecting it for the next time, adb will see it -- as you can confirm with the adb devices command. So here are the lines for your /etc/udev/rules.d/51-android.rules file:
#LG Optimus X4 P880
SUBSYSTEMS=="usb", ATTRS{idVendor}=="1004", ATTRS{idProduct}=="61a6", MODE="0666" GROUP="androiddev", SYMLINK+="android%n"

no root binary, doesnt work. followed your list EXACTLY

@gulio Above instructions were for the P880 running on ICS (as originally shipped). Maybe you try it with a different Android version? There was an update to JB provided, and AFAIK later devices even shipped with that. I cannot tell, as my P880 runs CM for quite a while already (currently Lollipop, but Marshmallow is ready as well).

HTC Sensation fastboot unknown device
I experience problems trying to root my HTC Sensation.
I turned USB Debugging ON, checked that Fast boot is turned ON in Settings > Power section and connected phone to PC.

My device was recognized successfully

Also it was shown in adb list
C:\sdk\platform-tools>adb.exe devices
* daemon not running. starting it now on port 5037 *
* daemon started successfully *

HT15LVXXXXXX    device

Now i took out my battery, inserted that back, pushed and hold Power button and Volume Down and voila, i am in HBOOT.
I pressed Power button once, choosing FASTBOOT

My phone connected to Windows, but this time device was not recognized.

I tried to add drivers for that device manually, but it failed

I even tried to add %MyHTC%=HTCAND32.Dev, USB\UNKNOWN to androidusb.inf and then add driver manually, but device was not working anyway and fastboot devices command returned empty list.
I tried same operations on my Mac using fastboot-mac for that and i got same result as on Windows - device is not recognized in fastboot mode.
Any ideas?

Well, two tips I can give you. 1) Fast boot in the settings has nothing to do with fastboot for flashing. The settings one is for not fully rebooting the OS to speed restarts. 2) The driver for fastboot is different than the driver for ADB. If you install HTC Sync it should install both, however. Sometimes you have to remove conflicting drivers using usbdeview or other tool.

Hey if somebody searches for an answer to this.
I have solved it by adding a key in the registry.
In Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\usbflags\0BB40FF00100 (The "cryptic" hex-number at the end is the VID, PID and REV value of the Hardware-id you can see under Details) if that key isn't existing (mine was) create it.
Then add a Binary Value SkipBOSDescriptorQuery and set it to 01 00 00 00
When I did that it "magically" worked on my Windows 10 vers 20H2 Build 19042.928 after a reconnect of the USB device.
Why does this work?
As far as I can deduce, this BOS Descriptor is a fairly new thing in USB 3 and was backported to USB 2.1. Windows is requesting that from the phone's USB device and that or the driver isn't new enough to consider/disable this BOSDescriptorQuery and only delivers garbage to device enumeration. The drive/OS is confused and refuses to properly work. My bet is that the driver for such of an old phone isn't worked on anymore to consider this failure mode.

Thanks!  Upvoted.  Can you explain what this does and why this works?

Thank you so much!  I added that great information to your answer.  Thank you again!

Why there is such a high activity within last couple of days about a telephone which was released 10 years ago?

you need to unlock thebootloader first before doing anything... the screen shot shows that your phone is still locked
you can do that on HTCDEV site

How can I recover corrupt files from my SD Card on my PC?
My LG Marquee started boot looping four days ago and because of this, I have not been able to get into my files (photos, videos, apps, etc.) and back them up. I have not backed up any of my files, unfortunately. A user on here gave me the idea to salvage my media content via copying my SD Card's contents to my PC, then copying these files to a new card and placing the new card in my phone - thus recovering my important files.
My phone is not rooted.
I bought a better SD Card and an SD Card reader and just tried copying my content to my PC. All photos and videos are showing up as Invalid Image :(
My Questions:

Does this "Invalid Image" prompt mean that the files are corrupt...forever?
Could this be caused by the software I am viewing the files in, and if I view them in a different software, will they show up fine?
Is there any way (via a photo recovery software) that I can recover these corrupt files? If so, what software(s) do you personally recommend?

Thank you for any and all questions answered.
I really appreciate it, I am at my wit's end with this problem and I had thousands of photos that were extremely important to me - losing them would honestly be devestating.
Update: I ejected the reader and inserted it again, and instead of being able to at least view the "Invalid" images, now my computer is prompting me to format what it is calling the Removable Disk (E:)
Should I go ahead and format my card on my PC? I'm so lost :(

Have you just unplugged it, or did you check the "safely remove" dialog of your PC's OS first? If you skipped that step, you might have added further damage. A suggestion is also to follow the data-recovery + sdcard tag link -- this kind of question is not asked here for the first time, so you already will find useful recovery programs mentioned and even described. See e.g. How to recover data from a damaged SD card?

I now realize that was my mistake. I did not "safely remove" the hardware. Yikes! Very bad mistake. Anyway, I was able to recover the files from PhotoRec. All of my files were recovered, though some of my MP3's were quite butchered afterward. That's OK though, I just really wanted my photos back and I got them. Thank you SO much for your help! I had an emotional attachment to many of those photos, and you and PhotoRec (as well as other users on here) have helped me to get them back when I thought there was no way :) Thank you very much!

Yepp, PhotoRec is a good choice. As your problem luckily is solved, I hope you don't mind if I initiate to close this question as a duplicate to the corresponding one ;) Glad I was able to help!

YouTube app on Android "signing in" forever
I use my Nexus 4 with a Google Apps account outside USA. There's no YouTube option in my GApps dashboard, as confirmed by this support page:

YouTube is not an available service for Google Apps in countries where YouTube has not yet launched. If you're a domain administrator in one of these countries, you will not see the option to enable YouTube as a service with Google Apps for your domain in your Google Apps Control Panel.
  http://support.google.com/youtube/bin/answer.py?hl=en&answer=1074205

I can visit YouTube in the web browser and that works fine, although I can't sign in. (I might be able to sign in with a dummy Gmail address but that would defeat having a Google Apps account.)
When I launch YouTube app on my Nexus 4, it promptly shows a banner "signing in..." but for the reason I just mentioned, this never finishes.
Does this mean I will never be able to use the YouTube app?! Does this really cause me to be completely locked out of YouTube on Android? That can't be right!

I recommend you to use a VPN Client to mask your original IP and circumvent lockout from youtube.
VPN clients I personally use are:

HotSpot Shield
Droid VPN
One Click VPN

All of it are Free but with some downsides. Hotspot shield gives you a US IP but will put small ads when you are browsing. DROIDVPN free version is limited to 100MB a day and requires to registration. One click VPN free has no ads and no limit, but you cannot choose your preferred country IP, it will be randomly chosen.

Galaxy Note II USB connection not working
On my Galaxy Note II (android 4.1.1), any time I try to connect to something over USB, it doesn't seem to want to connect. Specifically:
-iSyncr gives me errors connecting; so does Android File Transfer
-DoubleTwist and EasyPhoneSync can't connect at all
-Odin gets stuck at "Making Connection" (or something, I can't remember the exact wording)
These problems occur whether I have USB debugging on or not, and still persist when I mess around with the MTP/PTP settings. Does anyone have any idea what might be wrong? iSyncr used to work fine, but the others have always been broken.
Note: this is on a mac, and Odin is run through a virtual machine

What version of Android?
As of JellyBean 4.2.2, you'd need a newer version of ADB, as there's a security implementation built into JB 4.2.2, in that, any "unauthorised" computer with USB cable plugged in, will show the device as offline, rendering any file transfer/copying etc useless.
With the new version of ADB as downloaded from Google or for your device, you will be prompted to request authorisation and to allow it, based on a cryptographic key generated by ADB so that the computer is "trusted", then the contents can be copied/transferred.

Nope, I'm on 4.1.1.

Should have stated it on your question - kindly please re-edit to include your comment :)

How do I get Google+'s notifications into Android's notification list?
From iOS I'm used to seeing app icon badges and notifications concerning actvity inside apps. Android is lacking app icon badges but it does have a great notification menu -- except that Google+ notifications (the red counter in the black Google bar on all Google's web sites) don't arrive there. I do see the counter in the Google+ app (in Android as well as in iOS) but on Android there's no notification outside of the app.
I think it's weird that Google's awesome social network doesn't send notifications to Google's mobile OS.
I am hoping that it's merely some setting I need to enable on my phone to make these appear. Right?  I very much doubt that I really have to launch the G+ app to see notifications, given that so many other apps use Android's notification methods so successfully.
How can I see Google+ notifications in Android's notification list?

Uhhh...I get Google+ Notifications all of the time.
Check:

Settings | Apps | Google+ | Show Notifications is checked
In the Google+ app, Overflow menu (three vertical dots) | Settings | Notifications is ON. Tap that entry and choose which types of notifications to get. I see

Thank you! I saw the setting "Notifications" and it was listed as ON so I figured they were turned on... It is never evident from these Android menus that they actually contain sub-items... I still need to learn to operate Android, it's very different from what I'm used to.

Error on Samsung S3 with external memory card
My external 64GB ScanDisk Ultra is being causing me problems with my Samsung Galaxy S3. It works good for a small period of time, and then it crashes, it just stops working. It mostly holds music.
Suddenly it appears that there is not an external card, so I have to take out the card and reboot the phone, and then the card will work for another couple of days.
The phone is rooted, it works amazing, but Ive being having that problem. Is there anything I can do?

Is the terminal emulator app essential to CyanogenMod 10?
My Galaxy S2 is rooted and running CyanogenMod 10.
Amongst other apps, it comes with an app called Terminal Emulator, which I do not use. Is this app essential for CyanogenMod so I have to keep it -- or can it be deleted without causing any trouble?

The Terminal Emulator coming pre-installed with CM 10 (IMHO it is Android Terminal Emulator) is intended to let you access the command line. People using a custom ROM usually have use for such things -- and it is very helpful for certain kinds of troubleshooting, as via the command line you can directly access the necessary Linux tools to check certain things.
Aside from that, I cannot imagine it being "essential" to the system, so removing it should have no side-effects. But it would not bring you any benefit either: residing on the /system partition, uninstalling wouldn't give you more space in the "internal storage" -- and as the app only consumes other ressources when you start it, there's nothing to gain here as well.
It might prove very useful at some future point, so I'd recommend you keep it. If you really want to get rid of it: as with any other app you don't know whether it might be needed, first "freeze" (disable) it and watch carefully for possible side-effects (none to expect here), and after a week or so, if no side-effects appear, you can go ahead and drop it.

GTab with access denied to all app databases
I have a brand new GTAB (Android) that was working fine but suddenly, give a reboot while I was using anMoney, a very good application of financial organization.
Until anything I'd like to observe that I have plenty of space in NAND Flash storage memory, something about 100 MB. This storage is used to keep app's databases under /data directory. I'd like to observe that my ROM is original and android version is 2.2.

To turn things more intriguing, I bought an Andoid app called SQLite Editor and open the 3 individual databases given above. All 3 are intact, without presenting data loss or corruption.
What can be wrong? Any one can point me what is happening?

How do I run two programs at once in split-screen?
I have a Nexus 10. I want to split screen to do two things at the same time. Is that possible in Android? 3rd-party apps are acceptable too.

I don't think it can be done yet. The only thing that is close to it is small apps that run as overlay on the currently running apps.

As of this writing, only a few Android devices offer multi-window functionality out-of-the-box.  Samsung built this feature into 4.1.2 OS version for several of their Android tablets (Galaxy Note 10.1 and Galaxy Note 2, for example.)
There are some major drawbacks to this. First, it's a proprietary Samsung feature that only comes with their TouchWiz overlay, and therefore is not compatible with "vanilla" Android OS. Second, apps must be specifically written to support this feature.

While I don't believe that there are currently any window managers available for Android devices (except where some manufacturers, like Samsung may build this in) there are some other options that may work for you, depending what you're after, by optionally floating some other apps or features over or alongside your current app.

There are some third party Android web browsers that can "float" a window over your current window, and can be dismissed or brought to the front very easily: OverSkreen (formerly known as AirBrowser), or Floating Browser Flux
There are some small utilities like two calculators or Terminals that can also be floated over your current window.
Quickdesk is an app that can put a floating toolbar over other apps, giving you quick access to other apps.
If you're finding the keyboard is getting in the way, and you'd rather it floated over other apps, then you may find some of this question's answers helpful: How can I “split” the virtual keyboard when typing on a large display in landscape mode?
Although it needs custom written widgets/apps, you may also find that the Chameleon Launcher can do what you want as it specialises in arranging tiled windows of information/apps alongside each other (website).

Tested on a Samsung Note 10.1 (SM-P605) with Android 4.3 i found some apps which are supporting multi window, e.g:

My Files (*)
stock Video Player
MX Player
stock email app
Gmail
stock Webbrowser (*)
Chrome
Gallery
Contacts
Phone
Google maps
Polaris Office 5
WhatsApp
Facebook
Watch now
Chat on (*)
Google Play Store

But there are really very few apps capable to run with multiple instances (from the above list only those which are marked with (*)).
So, you can for example open My Files twice (left & right of upper & lower half screen)

Unfortunally, Polaris Office 5 (pdf viewer) isn't capable to run twice. So if you want to view 2 pdf docs side by side, it seems that you have to install a 2nd pdf viewer app (see here).

Sideload Xposed Framework and install the XMultiWindow module.

Open the XMultiWindow app from your app drawer to get started. Tap
  Sidebar Settings in the app, tap Sidebar App Settings, and use the Add
  button to add the apps you want to multitask with here. The apps you
  add to this list will appear in the sidebar so you can open them in
  split-screen mode.
Tap the Open Sidebar option in the XMultiWindow app to launch the
  sidebar, and then swipe in from the left side of your screen. The
  sidebar will appear at the left side of your screen above other
  running apps — it functions like a floating app.
To open an app in split-screen mode, long-press the app’s shortcut
  icon in the sidebar and tap Add to up Workspace or Add to down
  Workspace. If your screen is oriented horizontally, you’ll see the Add
  to left Workspace and Add to right Workspace options instead.
When you’ve opened the apps you want to use, swipe down from the top
  of the screen to open the notification shade and tap the Sidebar
  Running notification. This closes the sidebar, freeing up your screen
  space. You can always swipe in from the left again if you want to view
  the sidebar and open another app.
You’ll then be able to use both apps alongside each other. Here we’re
  watching a video while browsing the web — the kind of powerful
  multitasking that’s still impossible on most tablets and mobile
  operating systems today!

How can I make new/separate folders in the gallery?
I recently had some issues with my LG Marquee and had to copy the SD Card's contents to my PC, then put those contents onto a new SD Card to salvage my media content(photos, videos, apps, etc.) When I inserted the new SD Card with my content on it, my phone took the content but it all (all 3,548 items) were placed into one single folder in my Gallery.
My question is: How can I separate/organize these items into new and separate folders in the Gallery?
Is there a specific way on my phone that I can do this, or do I need to download a photo organizing app? If so, what photo organizing apps are safe and secure?
Thank You!

My work-around is connect my phone via USB mode, where it comes up as a folder (or volume for you Mac fans) that you can see contents in. Create folders you'd like to have in your gallery, like "Favorite Piks" or "Stuff I found in my pockets" - whatever. Put these in that folder.
Now use your computer to organize the images between folders within that main volume, save on your home computer, delete, so forth.
When you detach from the USB link, your gallery on the phone should show those new folders you created and the images you transferred over.
Please note that any NEW images, photos you download or take with the phone will likely be placed in one of any generic folders like "Downloads" or "Pictures".
t0mm13b's Edit
Pre-requisites:

ADB is installed.
comfortable with Command line.

By going onto the command line, and issue this command:
adb shell am start -n com.android.development/.MediaScannerActivity
The above command line will force Android to re-read the SDCard and quickly re-index all the just transferred pictures into the Gallery.

Sounds very ranty.... care to re-edit your answer! And for goodness sake, break up those sentences to make it easier to read. :)

I have re-edited your answer to remove rants and included extra information!

I tried to open my Gallery, but couldn't see any pictures on it.
Anyway, I use the QuickPic app to manage my photos. It is able to show the different folders that have pictures in it. Check it out.

Maybe the QuickPic app overrides the default "Gallery"? I have loads of pics in the "Gallery" and many of the "albums" within it are managed by other apps... "Camera", "WhatsApp Images", "Screenshot", "QrDroid", etc. as well as all my Picassa albums.

... Many of these "albums" are virtual and don't actually exist as folders on the device - at least not in the same way they are represented in the "Gallery".

I used Pics organizer to organize my pictures into different folders for my gallery. Download it here works well with other gallery apps.

CamStore does that job perfectly.

If you are affiliated with this app, please disclose that.

Scanning with Android
There are a few apps that seems to act like document scanners?
How do they work?  Is it more than a lot of posprocessing of one shot?
Are they actually "scanning" or utilizing more several shots?
What kind of phone specs do I need to have quick and reliable document scanning?

In my opinion, the word scanning in this context is a misnomer.
Basically the camera and the flash are the key hardware components involved in this operation.  The camera doesn't go into burst mode and instead takes only one good shot. The rest are the magic of software algorithms that straighten, finds boundaries and brightens and de speck the image.
The app Camscanner supports creating documents either from image or capturing with camera.
Higher camera resolution, the ability to autofocus and presence of flash (in absence of ambient light) are the features that are to be looked for. For shooting an A4 size with text printed with font size of 12,  a 5 mega pixel resolution is needed and with 3.2 mega pixels, I am able to capture A5 sized papers with very decent quality - observed from my experience.

+1 for the flash. Shooting documents under dim light most often produce blurry images that cant be corrected by software. Sensors account for the quality of the scanned image too. Brands like sony and samsung have great camera sensors over other brands (based on my judgement)

Why does my Nexus 4 not support WMA audio files?
My LG Nexus 4 (Android 4.2.2) does not play my .wma audio files. However, my generic/budget Android 4.0.3 tablet plays the same .wma files just fine.

Why?
How can I get my Android device to play .wma files?

It seems that ICS does not have native support for WMA files.
You can use an app like MX Player (or its Pro version) to play WMA files.

Yes, you are right... I see from the list of Android Supported Media Formats, that no version of Android natively supports the Windows .wma audio format! I guess my "generic" Android tablet isn't as generic as I thought and has the additional codecs to play these files?! Yes, MX Player plays these files OK - it does state in the docs that it's not a "music player", but you can add the file extension to Settings > List > File Extensions and it works ok. Thanks.

VLC can play .wma files too.

I didn't have any joy with MX Player or VLC, but I did find an app that played WMA songs on my android phone. The app that worked for me is called jetAudio Music Player Basic. The free version worked fine, so I haven't tried the paid upgrade.
My phone is Sony, not Nexus, so maybe that's the difference?

A bit of a workaround, but... If the music (.wma) files are part of your music library then you can sign up to Google's "Play Music" and upload all your library to the cloud (20,000 songs for free). The resulting streamed music appears to be in a format that the device can play.
The "Play Music" app still can't play .wma files directly that are stored on your device. However, the streamed music is saved/cached and plays offline.
The "Music Manager" that runs on your PC uploads all your music tracks (.wma files) to the cloud. However, it doesn't upload songs that are already in its music library. I thought this was maybe the key - that the same song already exists in a compatible format in Google's storage - but it works with any .wma file, even files I have recorded myself.
EDIT: If I download a track, that was originally a .wma file, from my cloud library on the web then it downloads a .mp3 file. This is the same for all .wma files - even files I have recorded myself, so Google must convert them.
