问:
Select which application to (NOT) update
I always knew how to disable the auto update for a specific app.
But since some time Google decided to forbid this useful functionality and force the users to update their app.
And I mainly do NOT use the Google Apps and don't want to update them (but I want to  update all my others non-Google apps).

How can I do it?

Before I could:

Go to Google Play

Select My apps

Select the desired app

Click the phone Menu button

Deselect the Auto-update tick box

Now is no more possible.
How could I achieve the same result?

Cant connect to my Wi-Fi due password length
Today I bought a LG L70 wich has android 4.4.2 and wanted to connect to my Wi-Fi, but after entering the password the "connect" button doesnt light up (it stay grey instead of black) it seems that the requiered characters to make it able to connect it's 5 and 13 characters, while my house password its 9 characters long, is there any way to make it able to input any lenght password?

My local wi-fi it's WEP, and I have no issues connecting to networks using WPA/WPA2, so this seems to be an issue with WEP only.

Troubleshooting 802.1x EAP connection
I actually have observed two issues, which most likely are related:

When I try to connect my phone (Motorola Cliq 2; Android 2.2) to 802.1x EAP protected network then the connection attempt seems to fail ~95% of time (the connection state changes from "Connecting"--> "Disconnected"--> "Connecting" --> "Disconnected" ... till it gives up). Five percents of time I am able to establish connections successfully (the connection state changes from "Connecting"--> "Obtaining IP address"-> "Connected")

Another interesting thing here is that Skype still works those 95% of time when my Android thinks that it is actually offline. I can send and receive Skype messages. Albeit Browser or any other WEB application does not work. The WiFi signal is at 80% and I do not have any data plan (once I leave the WiFi range then Skype stops to work)

I am new to Android platform so maybe anyone could give me hints where to look to troubleshoot these two issues? Maybe anyone could recommend tools which can extract internal information of WiFi connection state (the phone is not rooted yet, but I would not mind to do that if I have to).

P.S. The phone works perfectly fine with my WPA2-PSK configuration at home.

Moto E changes to wrong time or wrong time zone
My dad is using a Motorola Moto E, running Android 4.4.4 (not rooted).

He has noticed that it frequently displays the wrong time or date. Sometimes this is just the wrong time zone, other times it is completely the wrong time or date. I have set the time, date and time zones correctly, but they still seem to end up wrong again.

This seems to happen whether the options to use network provided time and network provided timezone is enabled or not.

Maybe it is due to him accidentally pressing the buttons to change this. But I have asked him about this, and he says he isn't doing this as far as he is aware. Or is the phone changing the time for some other reason?

Anyway, how to prevent this, and keep the time correct?

Difference between /mnt/local and /mnt/internal?
I have a WonderMedia 8650 based tablet running Android 4.0.3.  The File Manager app shows the internal flash file system as "/mnt/local", I can also see a "/mnt/internal" filesystem that's identical.  Running adb shell and using the mount and df commands I can see this:-

```<code>1|root@android:/ # mount
…
/dev/fuse on /mnt/local type fuse (rw,nosuid,nodev,relatime,user_id=1023,group_id=1023,default_permissions,allow_other)
/dev/block/vold/31:13 on /mnt/internal type yaffs2 (rw,relatime)

root@android:/ # df -h
Filesystem                Size      Used Available Use% Mounted on
…
/dev/fuse                 5.9G    119.0M      5.8G   2% /mnt/local
/dev/block/vold/31:13
                          5.9G    119.0M      5.8G   2% /mnt/internal
</code>```

To me it looks like /mnt/local is a "fuse" loopback filesystem sitting on top of /mnt/internal, but I have no idea what the fuse layer give me.  Does it add something like the virtual directories we see in the Microsoft Windows "Libraries" view?

My main concern at the moment is that I've had reports that files written to /mnt/internal have disappeared.  Is this something that might happen, and if so should I make sure we only ever use /mnt/local and leave /mnt/internal well alone?

Thanks for any advice.

Normalization - Automatic global Android media sound (music videos on YouTube) adjustment
I'm using this app: PVSTAR+. I have my list which plays in an endless loop, but the problem is that some YouTube videos are louder and some are quieter. I want the audio to be constantly at a certain "loudness level". What I need is a way to "normalizes" the Android volume on the fly.

I found an app called Waver - Volume Control, but it says it is not compatible with my Android 4.1 device; the app requires 2.3. Anyway, I downloaded the APK of waver and installed it but it seems not to be working.

Is there a way to adjust the media audio on a certain level automatically, so it automatically detects that the current audio is too low and increases it?

How to recover Chrome open tabs
I used to have the Chrome app with more or less 40 open tabs for some months. I opened it pretty often and it always restored all the tabs, until yesterday. I opened Chrome by mistake while I was having connection issues and it was not able to restore all my tabs. The next time I opened it, it only restored 5 tabs and the others seem to be gone. I tried searching for my tabs in Chrome history but I wasn't able to find them, instead I only see all the tabs opened in my other devices (PCs, Tablet, ecc.). I also tried to search for my tabs in the browsing history of my Google account, but I wasn't able to find them there neither: it seems that Chrome didn't load for real most of the tabs.
Is there a way to recover my open tabs? Does Chrome have a local history (opposed to the general history of the Google account which contains browsing history of all the devices used with that account)?</p>

How to view email in "Combined View" in 5.0 Lollipop
After updating my Nexus 5 to Lollipop, the Email app tells me that the Gmail app will now handle all emails.  However, I'm having trouble being able to view all email accounts at once in the gmail app.

In the old Email application, at the bottom of the list of email accounts was a "Combined View" option.  When selected, it would display messages in the inbox of all linked accounts.

Android 5: Bluetooth pairing dialog has no passkey form
I use several Bluetooth devices with my phone. Today I tried to pair a new one and was shown this dialog:

```<code>Bluetooth pairing request

Device
NWP-F110

Type the pairing code then press Return or Enter

Cancel                                      Pair
</code>```

No keyboard pops up. If I tap around inside the dialog, nothing happens. If I hit Cancel the pairing fails. If I hit Pair the device is registered in my Bluetooth system settings, but the app that works with it is unable to access it. According to the manufacturer, a passcode is necessary and apparently Android thinks so too, but I'm unable to enter it.

If I continue nonetheless and try to setup the device, the app searches endlessly. I'm never asked for the pairing code again until I manually forget the device in the system settings, yet no device is able to work with it.

Googling only shows me how to add the device as a trusted device, I'm unable to find any similar problems for Android 5 (although it might be because the OS is so new). Any tips?

I've confirmed that this is specific to my Nexus 5 running Android 5 - my Samsung S3 pairs with the device almost instantly and without trouble.

Google Now Accent Bug (Lollipop 5.0)
I updated to Android 5.0 yesterday on my Nexus 5.

I am from the UK, hence I have my languages set to "English (UK)" where possible, including the voice of Google Now, which has the accent of an English woman.

After this update Google Now appears to be partially ignoring my language settings in relation to accent. If I ask it something that Google can answer, such as "How far away is the sun", it replies with an English accent, but if I ask it to do something specific to my phone, such as setting an alarm, it replies with the accent of an American woman.

Is this a bug, a weird feature or is there a fix?

What does a blue/white arrow on an app icon in app manager mean?
The icon in application manager for one of the applications had a blue and white arrow overlaid on it for a while. Approximately the same time the app's icon disappeared from the home screen (pressing "apps" grid symbol for the alphabetical list of apps) and I could only start the app via Google Play Store when I was online. The app's shortcut I had created disappeared with it. (Android Kit-Kat, Galaxy Note 3)

I have only seen this arrow on the icon for the app TripAdvisor.

After a while the icon on the home screen reappeared and the arrow disappeared without me doing anything I can imagine affected the situation. (I could be wrong here, though.) A little before the problem (not being able to start the app since there was no icon for it) disappeared, I had just tried at random to clear cache, force stop and disable updates. Also restarting device, of course. Re-enabling updates made the app reinstall but the problem persisted a while longer.

It is not possible to uninstall this app, you can only disable updates. (But it has been downloaded and appears among downloaded apps in the app manager. It was not included with the phone. )

The app has not (cannot) be put on the external card. It has not been disabled.

I have previously had occasional problems with apps disappearing from the alphabetical grid/list. They're still installed and visible in app manager, but cannot be started otherwise than from Google Play Store when online. If I find out the meaning of this arrow maybe I can solve such problems.

Phone creates a Wi-Fi network (i.e. WiFi tethering) while being visible on said network. Possible?
I have a vague concept for a piece of software I want to write, but I'm facing a problem in that I'm not sure this is even possible with the way Android handles creating Wi-Fi hotspots in its current iteration.

Basically, the device needs to create a hotspot, while being present on the hotspot's network and visible to the other devices, since it needs to act as a server. Is this something that's currently possible on Android, or would you need two separate devices, one to create the network and another to connect to it and act as the server?

MHL screen becomes static anytime a new app is loaded
I have an HTC One m7 that I use to stream Netflix with over an MHL HDMI cable to a touch screen.

When I was running ViperOne 7.0.1 I would only occasionally see this and it would regain the video feed after becoming static. It is random and not repeatable by any particular steps.

Now I am running Cyanogenmod M12 (latest snapshot) and any time I open Netflix, I get permanent static until I unplug and re-plug the MHL cable. Also any time a new app loads or a new Netflix video loads, I'll get static until pulling and replugging in the cable.

Given that it works fine in one ROM and not so well in the other, what is the missing link to getting this to work reliably? Is it the kernel? What can I do to figure out the problem?

Android 5.0.0 on Nexus 5 stuck on boot logo
I just recently received the 5.0 update for my Nexus 5 and now my device fails to boot. All that happens is the Google logo gets displayed on the screen and then the device does nothing else. I am able to get into both the bootloader and recovery.

First I tried wiping the cache with no results. Next I did a full factory reset with no results. After that I decided to just flash the factory images directly. Unfortunately this didn't work either. I went back into recovery and discovered that there were a series of error messages displayed in the recovery menu...

```<code>E:failed to mount /cache (No such file or directory)
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/log
E:failed to mount /cache (No such file or directory)

E:Can't open /dev/block/platform/msm_sdcc.1/by-name/misc
E:failed to mount /cache (No such file or directory)
</code>```

Also after these messages were displayed I could not wipe the cache or do another factory reset.

Luckily I am able to flash the 4.4.4 factory images and boot the device successfully so my guess is that something might be going wrong with the installation.

Has anyone else encountered similar errors when updating to 5.0?

Trying to flash CWM but fastboot hangs at "writing 'recovery'..."
I'm trying to flash my Coolpad 8865u (Vodafone Smart 4 Turbo). I unlocked fastboot
and fastboot oem device-info confirms this. However when I try to flash CWM the prompt on my shell hangs at "writing 'recovery'...". When I unplug and replug the USB to get it unstuck it stays "Failed (status read failed (No such device))".

However when I force a reboot it works fine.

Also I don't know if I'm doing this correctly but when I try to get into fastboot mode by pressing the power button and the +/- volume buttons the text "OFFICIAL" is displayed at the bottom of the screen and the phone vibrates but it does not get me into fastboot mode. It just reboots and keeps rebooting until I release the buttons.

Volume up and Power does get me into recovery mode though but there is no option to go to fastboot from there.

Obtaining boot.img for unrooted device?
I have a Vodafone Smart 4 Turbo / Coolpad 8865U. I cannot find other means of rooting it and to be honest I don't trust most oneclickroot.apks. I am trying to root it manually but I cannot find a way to obtain a boot.img.

I managed to get a .CPB  file which I believe to be the firmware for my phone though I am not sure. However I cannot find a way to unpack it either.

So how can I obtain a boot image for this phone or manage to unpack the .CPB file?

EDIT: I made progress but I'm also back to square one. I found a tool called cpbtool.exe that successfully extract the *.cpb firmware. I then obtained boot.img from there. Modified it so that it boots insecurely and tried to boot the now insecure image using fastboot but the thing just hangs at "booting..."

For some reason it seems like fastboot doesn't really work on my coolpad device despite being oem unlocked.

Automatically verify signature on all Android Exchange emails
I work in an office where everyone uses a digital signature on their emails.

Samsung Galaxy S3 update deleted Play Store and a bunch of other Google apps
Today my Galaxy S3 alerted me that there was an update to Push Services available. For once I actually thought "hey, let's not dismiss this update" and went through the whole process. There were no warnings, nothing seemed strange, and everything seemingly worked smoothly.

So I tap the Hangouts icon on my home screen (Apex launcher, if that's relevant in any way). "App not installed". Okay, uh, let's install it, then. I tap the Play Store icon. "App not installed". That's a problem.

A bunch of Google apps seem to have been uninstalled. Play Store, Hangouts, Calendar, and probably a few others. I've looked in my System settings > Application manager > Turned off, and they're not there - in fact, they're not anywhere in my applications list at all! Instead, Samsung seems to have installed "Galaxy Market" and a few other apps which are mostly worthless to me. Here's a list of things I have tried so far:

Checked if they were perhaps just disabled (they weren't).

Downloaded APKs for both Play Store and Hangouts. The installers tell me "Do you want to install an update to this built-in application?" for both of them, then "Application not installed".

Contacted Samsung's support center. I got a copy-pasted answer about factory resetting, and I'd rather not do that.

Rebooting. Nothing.

How do I get these apps back? I use Hangouts every day, and Play Store is just plain hard to do anything without.

问:
Android default keyboard phoning home to Google?
I installed CyanogenMod 11 on my HTC One (M8) the other day and, so far, have only installed DAVdroid for contact synchronization and Network Log. So, out of curiousity, I let Network Log run when I added my contacts in order to verify that DAVdroid indeed only connects to my server. Turns out it does. However, I noticed that CyanogenMod's default keyboard (which I assume is more or less Android's default keyboard?) connected to an IP with a *.1e100.net hostname – which belongs to Google. I've taken a short look at the keyboard's source code – which I believe is this one – and think I found something like an update function for the dictionaries but also some kind of upload functionality?! I don't know where the hosts are stored, though.

Can anyone familiar with the code tell me:

What the upload function is there for and

whether the above findings explain my observation (do the updater and uploader indeed connect to Google?) or whether I missed any network-related code?

Finally:

Why has noone thought about the fact that having the keyboard connect to some Google host isn't the smartest thing and is bound to make someone suspicious?

Why can't dictionary updates be done the usual way via the PlayStore? (I don't think languages change that fast, so the occasional download via PlayStore would certainly not annoy anyone.)

UPDATE: I tried to reproduce the observations, this time with XPrivacy installed (I in principal enabled all permissions for all apps as long as they are listed in their manifests): Turns out, I can't. In XPrivacy, I noticed that the AOSP keyboard doesn't even have the necessary permissions in its manifest to access the internet. So, I'm not sure whether I just saw some ghost the other day or if the keyboard is run with root privileges or it's what they call a system-privileged app both of which might explain why it can establish a connection, anyway.

On the other hand, this time I also noticed some background service called "input devices" connecting to Google. So either I mistook this service for the AOSP keyboard (which I doubt because I wouldn't have thought of the "AOSP" term) or we have two apps / services ("AOSP keyboard" and "input devices") connecting to Google.

In any case, the update/upload functionality mentioned above still raises questions.

Google Events and Contacts not Showing Up in Outlook
I own a Nexus 5. I have an Office 365 email account that I use to run my small business. When using KitKat, if I entered a contact or calendar appointment in the contact/calendar app that I was using, it would automatically show up in Outlook and Outlook appointments would show up on my phone. Since the download of Lollipop, appointments and contacts entered into Outlook show up on my phone, but appointments entered on my phone (as "events"), and contacts, don't show up in Outlook. As my staff has to be able to book me appointments and see my availability to do so and I am on the road a lot, this is a serious negative.

How do I customize sleep timeout button presets in quick settings panel?
Here is an image to make clear what I'm talking about:

As you see, this button have 3 positions. I figured out what these are corresponding to Sleep after 15 sec, 30 sec and 1 min, respectively.

Problem is, I use my 4.2.2 tablet for reading pages of text (like e-books or manuals), and my optimal timeout for everyday reading is 2 min. So neither preset suits my needs and it renders this button rather useless.

Moreover, this button gives me hell when I accidentally touch it, because it resets to the one of preset timeouts and I have to visit Settings and restore my preference.

How I customize these preset timeouts?
Alternatively, I'd like to know a way to remove offending button.

Thanks!

Flashed system partition differs subtly from system.img
When I flash my Nexus 7 2013 with a rebuilt aosp system.img using fastboot, the data in the partition (as read back by dd) is very slightly different from the system.img data used to flash it. A block of "20..." bytes appears to have moved.

Any idea why? The partition isn't mounted rw at any point (that messes it up even further by setting the superblock s_mtime and s_wtime values).

Update: Actually it seems that just a byte at offset 0x560 has been changed from 0x00 to 0x02. Now that I dig into the details, this is the s_flags of the superblock, with 0x02 representing "Unsigned directory hash in use", which would make some sense (although "Signed directory hash in use" would make more sense given I'm using dm-verity).

I still don't think it should be modifying the data given that it is never mounted rw though...

Can't access S/W upgrade mode
I have a LG 4x HD ( P880 ).

I have rooted it and tried to install a rom but the error : " invalid image signiature " turned up when trying to turn it on and it shuts down right after.

My idea was to reflush it, I plug in the power cord, take out the sim and the battery but when I open it up it doesn't go into the s/w upgrade mode. If I don't hold down any key it goes into a random-colored window and otherwise no matter what key I hold it turns blank black and nothing happens. I know it is supposed to go into the s/w mode by pressing vol - but that just sends it to the blank black screen.

I did reflush it before and it worked just fine, didn't had any problems getting into the S/W upgrade mode.

App to OCR pre-existing PDFs?
I am in grad school and have a samsung galaxy tablet that I primarily use for reading and annotating PDFs. Many of these docs are scanned book chapters and have not been run through OCR before I download them to my tablet. I'd like to be able to run them through an OCR app so I can search the text. On my PC I use Acrobat Pro, which has this feature built in, but there doesn't seem to be anything comparable available for Android. I use EasyPDF Reader Pro to read and annotate PDFs on my tablet, and really like it, but it does not have an OCR feature. All of the OCR apps I've found on Google Play and by searching online seem to be geared toward recognizing text in photos and some will output a PDF, but none seem to take an existing PDF as an input. I suppose I could just convert the docs on my PC and reload them from there to the tablet, but this is a hassle and seems to defeat the purpose of having a tablet. Any suggestions on an app I've missed, or any OCR developers out there who want to cook something up that would be really helpful to all of us grad students?</p>

How to root the HTC Desire 300 (also known as Zara Mini)
Okay please forgive me if this has already been answered, I've read a few questions on here but I still don't understand.

Firstly, I'm not a "techie" or anything like that, so some of the really smart words and language are a bit overwhelming for me.
I'm only just thinking of rooting my phone but have no prior experience with hacking, jailbreaking or anything like this.

The only reason I want to root is to delete apps that I cannot disable that I never use and are slowing my phone down and taking up ram. Is rooting even worth it if I'm just wanting root access to delete some applications?

And I'm still a bit confused as to the security side of things, am I still protected from malware/hackers/etc as long as I don't give root permission or access to certain apps AND keep s-on (which I just found out about).
For example, if I root my phone are my passwords for facebook/email/etc vulnerable, as we as my texts and phone contacts information and stuff like that?

Like I said, I'm a fish out of water here so please forgive me if these questions a bit silly.

  Suggestions for syncing data to someone besides Google? Funambol?

The idea is to cut Google's (or other 3rd-party) proprietary bits out of an Android installation, while retaining the benefits of "cloud" computing.  For most things there are open-source alternatives: SK for keyboard, K-9 Mail for e-mail, etc.  However, for the core "cloud" services like Contacts and Calendar, all replacements that I've seen simply redirect you to their own closed and proprietary cloud servers.

From a quick search around the web, the closest open-source alternative is Funambol's client/server solution.

Samsung S Galaxy II (i9100): possible with stock Google Android OS?
I'm in the market for a new Smartphone. Except for iPhone's, I'm new in the field and probably have some misconceptions.

My first choice was the Google Nexus S, but I was offered a great deal on the Samsung S Galaxy II (i9100). The only issue is that I read that it came with an "enhanced" version of Android. Being familiar with PC's, I know that these enhancements are almost always bloatware: I always do a clean install of Windows to get rid of it.

My question is fairly simple: is this possible to use the stock Google Android OS on the Samsung S Galaxy II (i9100)? That was the killer feature of the Nexus S for me: coming directly from Google, easily upgradable. Would that be possible and if yes, how?

Merged contacts keep separating (Google and LinkedIn)

First of all, it doesn't always happen, and I can't reproduce it now. It seems to be correlated with auto-reloading after a long time off the Internet app. It had an analogue on my older mobile, with two fundamental differences:

I have the impression it happened much less often;

The old version had a "Continue" button underneath, meaning I could just tap and ignore the problem, though it sometimes popped up again shortly afterwards.

I got it again. Here it is:

Accepting Calendar invites not showing in calendar
My company uses Gmail as our email and calendar. When I receive an invitation and accept it on my phone (Samsung Galaxy S4) it never puts it in my Google calendar. I have to wait until I get to my computer to accept. This occurred on my S2 as well. A co-worker has the same problem. When I accept it opens my browser and shows that I've accepted but never makes it to my calendar. Any ideas on how to fix this?</p>

SMS sent contains text from other SMS
I sent an SMS and my contact received only part of the message I sent, to which some text I sent to another contact, a few months ago, was appended. I have proof it happened twice, but here is what it looks like:

September : I send ContactA a message: "AAA AAA"

On my phone : "AAA AAA"

On ContactA phone: "AAA AAA"

On ContactB phone: [Nothing] (As you would expect)

December : I send ContactB a message: "BBB BBB"

On my phone : "BBB BBB"

On ContactA phone: [Nothing] (As you would expect)

On ContactB phone: "BBB AAA AAA"

I checked with my carrier, and he told me that he saw that the text I sent ContactB was 11 characters long (it was actually way longer than that, but I ajusted the number to fit the example.)

The first time I got a proof it happened, I was using GO SMS, so I uninstalled it, and it happened again a day after using the default (Hangout) application.

I think this is a really serious problem since it violates my privacy with ContactA by revealing some conversation to ContactB.

No IMEI on Samsung Galaxy Ace
A week ago, my sister gave me her Samsung Galaxy Ace S5830I. She said that she could not call or text anyone and could not receive anything. I looked around on her phone and on the Internet to find the root of the problem. I found that the phone had no IMEI number. I typed *#06# in the keypad of the phone and a box appeared. It had the words "IMEI" but there was no number under it. When I go to Settings > About phone > Status, this is what it says:

```<code>Network: T-mobile UK
Signal strength: -83 dBm 14 asu
Mobile Network type: UMTS
Service state: Out of service
Roaming: Not roaming
IMEI: Unknown
IMEI SV: 01
</code>```

Bizarre new battery behavior on Samsung Galaxy S3
After my old battery puffed up, it was time to buy a new one for my Galaxy S3 (GT-I9300) on stock ROM. After I got my new battery, I put it in and turned on the phone as I had some urgent messages to check. I was supposed to charge it to the max but I skipped that part because of urgency.

Well, I noticed that the screen flickered when the battery was 23% and the phone switched off. I decided to charge it to 100%. After I got the green light I turned on the phone and I noticed that the battery jumped down to 88%; indicating that I needed calibration.

I tried the good ol' discharge-recharge to 100% method, but the battery wouldn't go below 23%. I decided to use some app, like Advanced Battery Calibrator. After following the on-screen instructions, it asks to switch off the phone and let it charge to 100%.

The bizarre part is that as soon as the battery reaches 90% (in switched-off mode). it jumps back down to 20%.

I do not know what is causing this. Any leads would be appreciated.

Boot to lock screen with encryption
After upgrading to Android 5 on my Nexus 10, I've now gone the extra step and enabled encryption. One thing that bothers me though: It doesn't boot to lock screen any more.

I get asked my lock screen code early in the boot process - which is fine - but then after the boot, the device is immediately unlocked. I'd like to boot to the lock screen instead.

Is that possible with a (rooted) stock ROM? I wouldn't mind messing with system files to achieve this, but of course an option somewhere or an app would be nicer.

Intent to select Android Security Screen Lock type
The Screen Lock on Android phones has been a point of contention for me for years. The only alternative I've discovered is to us a Tasker plugin called Secure Settings, which has an option to enter a PIN/Pass, or to clear the PIN/Pass.

Are there not specific intents available to allow direct change of the screen lock type, i.e. None, Slide, PIN, Password, etc? Basically, a better, conditional-based means of Google's Smart Lock feature.

Android phone will not show all WiFi access points
I have a LG-D686 running its stock factory installation of Android 4.1.2 Jelly Bean; modified somewhat by the vendor to support a dual-active SIM card transceiver. Normally this phone has had no difficulties finding and connecting to WiFi Access Points.

However, I now work in an office whose WiFi Access Point is not showing on my Andoid phone.

This is what I know:

The office WAP is not an ad-hoc wifi hotspot. It is an always-on Linksys LAPAC1750 Pro.

The office WAP is visible from my Windows 7 work laptop and from other colleagues' iPhones. I've not checked if anyone has an Android Jelly Bean phone in the office.

My Android shows up most but not all access points in the building. There are approximately 15 - 20 access points visible from my Windows laptop using Xirrus Wi-Fi Inspector; depending on the time of week. Android Wifi Analyzer shows that as much 80% of laptop-visible WAPs are visible on my phone.

The office WAP has a decent signal; more than most WAPs that are showing up.

If I create a non-ad-hoc wifi hotspot on my laptop (using Connectify); this hotspot will be visible if the laptop is not in the office and invisible if the laptop is in the office!

No obvious and evident differences between visible and invisible WAPs other than the office access point is the only one in this building using channel 12.

What might I do to resolve this WAP visibility problem?

Disable automatic connection to weblogin networks
As far as I know, Android never had the option to disable automatic connection to specific Wifi networks, and always, stupidly, makes Wifi higher priority than 3G. Yet this kind of feature is crucial in urban areas with abundant open web login networks in cafés etc. Even Symbian on my old Nokia 5800 XpressMusic had the option to order networks manually, so that 3G could have higher priority than certain Wifi networks. iOS6, as a worse substitute of this ordering, also used to have the option to disable automatic connection to specific wifi networks. But that is gone since iOS7, so switching to Apple does not solve my problem. Has anyone figured out a hack, a third party app or so, to get this crucial feature on Android phones?

(I currently have Motorola RAZRi, and am extremely frustrated, since the one and only Jelly Bean upgrade 1.5 years ago made it unrootable and slow, and Motorola has provided no upgrades since then. I'm also frustrated by Android's region locking, not allowing me to install my bank's app while living abroad. Since iOS region locking -- while still evil like all DRM -- is softer, only based on the AppleID account, not the device itself, I'm considering switching to iPhone unless this Wifi issue can be solved more satisfactorily on Android.)

Internet searches turn up nothing, only other questions of the same fact, and answers saying "the asker is an idiot and this is standard behaviour on all mobile devices and how things should be". Maybe this attitude stems from different culture -- the US culture from where the tech companies offering substandard products come from -- where there are perhaps few weblogin networks? But in Europe the situation is different. It is frustrating to have internet stop working on the street, because instead of 3G, the phone has connected to a web login network radiating from the nearby café, e.g., the very common _TheCloud in the UK. At the same time, having wifi enabled is crucial, because even at my home in the centre of an important university town there is in practise no 3G -- not to even speak of LTE, for which I would not pay on this island that has worse signal quality than the third-world countries I've visited. In many cafés in particular there is no 3G reception, and a frequent need to use _TheCloud. The option of manually forgetting a network after each use is a purely unusable alternative, moving the task of remembering from the device to the user – yet IT should ease our lives, and have an option that needs to be set only once and forgot!

Contacts app: What does the small colored green or orange circle above the account icons mean?
On my Samsung Galaxy SIII when I view my contacts list in the Contacts application each contact entry has a list of small icons on the lower-right hand side corresponding to accounts where that contact is listed such as Skype, Google, WhatsApp, etc... as
shown on the following screenshot (contact pictures and names have been scribbled
out for privacy reasons, click to enlarge):

Above the list of account icons, for some contacts either a green circle with a white circumference or an orange circle with two white clock hands and a white circumference appears in the upper-right hand corner of the contact entry in the list. Obviously green means available, and orange means away, but I am unable to figure out which of the three applications Google, Skype, WhatsApp, other, or whichever this dot corresponds to. First I thought that if the green dot was above the skype icon, then the contact was available on skype, but the last time I checked one of my contacts was associated with only one account,
namely skype, but when I logged into skype the contact was offline.

Can someone please help me figure out what the green or orange dots in the upper-right hand corner of contact entries in the Contact application mean?

Thanks.

How to see Appointment Info in E-Mail Calendar App
I have a Motorola Android Phone with KitKat (however I think this issue applies to Android in general).

When I receive some appointment on my Exchange Account, it appears on the inbox, however the main view does not show any details about the appointment. So I have to open the "Appointment" tab and show the item in the Calendar, I have no other way to see the details of the appointment.

This is OK for new appointments, as looking into the calendar makes sense. However, it is common that appointments are changed, and this pattern does not help me to quickly recognize what was changed (location, description, timestamp). Worst thing is that opening the "changed" appointment in Calendar often does not even show the correct time (it just insists on the original time from the appointment).

I would like to see a view that shows exactly what changed on the appointment. Is there any way to get such a feature? I would even be willing to buy an app if it is necessary... :)

How can i run At-commadns with the ADB?
I'm trying to communicate with the modem of my Samsung Galaxy S3 GT-I9300 over the ADB tool. My galaxy is rooted and is accessible through adb.

I'm attempting to execute AT-commands over the adb-tool.
I already tried a few AT-commands but the modem doesn't respond.

First of all I was running cat /proc/tty/drivers to get the right driver. my output:

```
root@m0:/ # cat /proc/tty/drivers
/dev/tty             /dev/tty        5       0 system:/dev/tty

/dev/ptmx            /dev/ptmx       5       2 system
/dev/vc/0            /dev/vc/0       4       0 system:vtmaster

unknown              /dev/tty        4 1-63 console
```

Consequently my driver address is /dev/ttyGS0, so I run the next command echo -e "AT\r" > /dev/ttyGS0 but the modem doesn't respond and nothing happens:

```
root@m0:/ # echo -e "AT\r" > /dev/ttyGS0
root@m0:/ #
```

So I quit the tool and tried another command service check phone:

```
130|root@m0:/ # service check phone
Service phone: found
root@m0:/ #
```

It looks like it at least found a kind of a modem.

So, I Google a bit and I find a nice tool called microcom, which is included in busybox. I installed busybox and tried busybox microcom -t 5000 /dev/ttyGS0, but the output was

```
root@m0:/ # busybox microcom -t 5000 /dev/ttyGS0
microcom: applet not found
1|root@m0:/ #
```

I really hope you can help me to find my problem with my code or suggest some better commands.

When creating a SMS with Google Search using my voice, Hangouts is not an option for sending
While driving, I may tell Google Search with my voice to "Text ".  Google will ask me what the message is, and eventually after completing the required back-and-forth, my phone prompts me to select an SMS application for sending.

I'm presented with Messages (i.e. the default Android SMS app) and Google Voice, but Hangouts is not one of the options.

In other applications where I may "Share" something, Hangouts is an option there.

ICE (Emergency) contacts from lock screen - how to access when SIP is configured?
Using Android version 4.4.2 (on Samsung Galaxy S5 Mini).
I have added one of my contacts to the OS built-in ICE contact group and assigned to one of the four emergency contact buttons that are shown when selecting "Emergency Call" from the lock screen.
However, since configuring the stock SIP (VoIP) client, the phone prompts the user to select Mobile Call or Internet Call before making the call.

问:
Can't view Location (textual desciption) information in Windows when opening picture taken with Camera app
On my Samsung Galaxy SIII, I have enabled GPS on my device and have also enabled the GPS tag feature in my Camera application. When a picture is taken, GPS information is attached to the image, and then as soon as either a mobile data connection or Wi-Fi connection is available, somehow the Gallery application is able to retrieve textual information about the street name, city, and country, corresponding to the GPS location stored with the image. When I press the menu hardware key and then select Details I can view this information alongside other information associated with the picture taken.

However, when I attach the phone to my Windows 7 PC and open a picture directly as Computer -> GT-I9300 -> Phone -DCIM -> Camera -> date_sequentialnumber.jpg I am not able to view the embedded textual/alphabetic location information which I was able to see when I was viewing the picture in the Gallery application.

So, what I would like to ask is:

Is it possible to embed the textual location information in the image (besides just GPS coordinates) as EXIF information inside the JPEG so that this information can also be viewed on the PC even when the PC has no network access?

If this information is already embedded but not being displayed by the Windows Live, then are there better, free, image (and video) viewing programs for Windows 7 which will allow you to view this information?

EDIT:

According to this Wikipedia article, the process of enriching geographical coordinates with a description of a location is known as reverse geocoding. This is what the Gallery application above was doing. Also according to this other Wikipedia article Geotagging can also attach not only coordinates, but also place names, which is what I'm after. The EXIF standard does not seem to include any specific tags for place names, although camera manufacturers can embed their own custom format metadata using the MakerNote tag. Upon searching for images with the Advanced Google Image Search, downloading, and viewing with Gimp 2.8.4 I found place name information embedded in the ImageDescription EXIF tag, whereas images downloaded from Panoramio it seems do not contain EXIF informaiton.

So, my question is, how do I embed reverse geocoded place name information inside the ImageDescription EXIF tag of pictures from within my Android smartphone? Thanks!


问:
What causes latencies in the 1-10 second range?
I use my mobile phone as access point now and then. Both home and abroad I have regularly experienced extremely high latencies (10000ms) with fairly low packet loss (5%).

What causes this?

I have read How can I reduce latency while tethering? but that only answers what I already know: That it is due to wireless at the carrier.

So the question here is to get more details.

I never see the above behaviour in a wifi net (I will typically see loads of dropped packets, but a reasonable latency lower than 1000 ms), so something else is going on.
If I only get 5% loss, I imagine there is some store-and-forward going on: Where does that happen? Why can packets not be passed on for 10 seconds, but still not be lost?

If the carrier wanted to do something about it, what should they do?

Stream FLV/MKV Files From a Windows Phone(Lumia 520) in Android Phone(Nexus 4)
I have a Nexus 4 (Lollipop) & a Lumia 520 (Windows 8.1)

Since, Nexus has limitations of Data size & Lumia supports a microsd, Most of my Videos/movies are stored in lumia 520's SD card.

Almost all of these happen to be in flv/mkv format which unfortunately is not supported by windows phone.
There are apps which claim to support mkv in lumia but have a lot of defects in decoding.
I tried mkv viewer,ccplayer, moli etc. but the experience is pretty disappointing.

So, I need a way to create a peer to peer network such that Lumia 520 acts as a media server & streams videos(no downloads.. all in memory as there is insufficient data space) to nexus 4(which can play these videos excellently).

There is an app in Windows store (Lumia Play To) which can cast screen to other devices.

Using BubbleUPNP on Nexus 4, I could get Nexus 4 to be seen in Lumia & works good.
However, this approach has two limitations :

1) You need a separate wifi router/network to which both devices can connect.

2) Lumia Play To cannot stream mkv/flv videos.

There is also an app (Easy Transfer) for windows which shows phone files via Browser.
This shows flv/mkv files but it does not stream videos.
Rather, it downloads the video & that is very slow. Also, a separate wifi network is needed.

So I need a Way/Apps wherein I can create a Wifi direct network between these two devices & watch videos in nexus 4 without fully downloading them.

(The last four words might be too much to ask but if at all it is possible, that would be good.)

Using the tablet for cell phone calls
My tablet is a SurfTab xiron 7.0 3G. It can take two sim-cards (dual sim-capable). I can receive voice calls over the bluetooth headphones. It does not seem to be able to alert by a ringer or flashing screen, when a phone call comes in and the bluetooth headphone is not turned on. Furthermore, I do not seem to be able to make outgoing calls. But I can send SMS'es from either of the two on-board SIM-cards.

I installed various apps - e.g. Talet talk. But none of these apps make use of the sim-cards on the tablet it-self.

Is there an app or any other fix out there, that could assist me in making voice-calls from the on-board SIM-cards? I am not interested in VOIP solutions (I use Skype extensively), as I must be able to make and receive calls, when in areas with no internet connection.

How can I force the Google Sheets app to update to the server?
I have been using the Google Sheets app a lot on my Android phone, and I have discovered that if I don't force the app to store the spreadsheet to the server, it sometimes loses updates.

This is the sequence I currently use to force the app to save to the server:

Clicks the check mark at the end of the "fx" input box.

Click the check mark at top left.

Click the "<" mark at top left.

Click on the spreadsheet again, and scroll back to the desired position.
That's a lot of steps for something that happens automatically after just a few seconds in the browser version, and pretty annoying (though not as annoying as losing data).

So, the question: How can I more expeditiously force the Google Sheets app to update to the server?

Recovering lost or stolen phone (security and feasability considerations)?
I am trying to understand a little bit about security in case my phone goes stolen. I have read that even if a phone is stolen and the SIM card is removed, it can still be possible to find your phone because the hardware has a built-in International Mobile Station Equipment Identity (IMEI) number which gets transmitted at regular intervals over the mobile network. Apparently this number can be changed in the software in the same way that, for example, the MAC (Medium Access Control) number of a hardware device such as an ethernet card can be faked on Linux via software methods, but it appears that doing so is not legal in most countries as it could help people stealing your device. So, here come my questions:

Am I correct in assuming that if the device is turned off (either manually, or perhaps because the battery runs out), then presumably the IMEI cannot be tracked until the device is turned on, which means that the device can go lost this way? Or is there some Android app which can reveal the location of your phone even when the phone is powered off (perhaps a phone which is powered off still uses a minimal amount of battery to make this IMEI information available to the carrier, or maybe via GPS given that GPS does not require a SIM card to be present to operate)?

Thanks.


问:
Is there a list of android system status bar icons?
I'm not sure what some of the status bar icons mean on my Android Nexus 5 device (I'm referring to the icons in top right of screen, adjacent to the time). I've googled frequently but I keep getting back a list of icons to use in app development. </p>

<p>I'm looking for a list of the system status bar icons and an explanation of the meaning of that icon. I'm interested specifically in the vanilla Android Lollipop OS on Nexus.  </p>


问:
What is the command line syntax of ClockworkMod recovery?
Background: I recently broke my phone's touch screen; everything else is working - I can even send inputs using adb shell sendevent ... and view the screen with screencap. ADB while in recovery works as well.

however, since the recovery doesn't have the screencap utility, I can't really do anything in recovery mode. I have found the recovery utility, though.

The recovery command though has no help as far as I can tell; there is no man, and neither recovery -h nor recovery --help show anything. Unsettlingly, the command doesn't even terminate immediately.

Are there any resources on this utility, especially on how I can do a full system backup like I would using the options on the screen?

Accidentally renamed APK file of default launcher
Yesterday, I was exploring my phone's system files and I accidentally renamed apk file of launcher when I was exploring /system/app folder. It renamed to "Launcher2.ap" but I absolutely know it's original name is "Launcher2.apk", so I noticed that and I renamed it back to "Launcher2.apk" and it was running normally. But today, I can't get any screen after boot (but it's booted normally) and there is no notification bar, no back/home/menu buttons and no errors have shown. I googled all solutions for this malfunction (including this website) and every solution says "you can fix this via adb" but I can't open USB debugging mode, because of blank screen. I also tried "wipe all cache and data" in boot recovery mode and tried to install a new launcher via Google Play's Website but the result is same: blank screen. What can I do for this error? Sorry for my english.

Note: The phone is rooted and it is automatically connects to wireless router (am I lucky?) and sometimes the "back/home/menu" bar and notification bar is flashing (~0.3sec) for once and then it goes blank screen again.

Thanks for any idea/help.


问:
Nexus 5 > Lollipop upgrade notification lost
I have an LG Nexus 5 and I am running Android 4.4.4 on it.

I've been seeing a notification telling me there's an upgrade for my Android OS for several weeks now (Lollipop upgrade), but I've been waiting till I properly back up my phone before starting the upgrade.

When I was finally ready to run the upgrade yesterday, the notification was gone. I went to Settings > About phone > System updates, clicked on "Check for update" only to find it saying "Your system is up to date".

The "Last checked for update at" message was changed to the current time.

Rebooting the phone and trying again did not help either.

Is there anyway I can get that Lollipop update back?
