问:
Analyse performance / profile Android System? Why is the system slow?
My Android 4.2.1 tablet is slow, it wasn’t when purchased. As the reason is often the software, I was looking for a tool to analyse the performance of the whole system, but couldn’t find any.

What I tried:

CPU usage monitoring: Only current or accumulated CPU usage

An app that alerts when any app uses more CPU than a specified threshold: This only alerted quite seldomly, so there doesn’t seem to be an app that uses so much CPU itself

To find out the reason of the slowness, I would like to get an overall view of the system’s performance, showing how much time was spent with which activity. This may include CPU usage, but may also include I/O performance or how long processed waited for I/O etc. For example, Firefox offers a profiler.

Or is this not really possible because of Android’s design?
Are there other utilities that might help?

Another point is that Android doesn’t support TRIM until 4.3. Could the usage of nearly two years with many installations and some system resets have caused the flash memory to get so slow that the poor I/O performance now slows down the whole device?

To the manufacturer’s support, I wrote the following problem description:

Opening of apps takes longer, sometimes everything stands still for
  some seconds. After the last firmware/Android upgrade (a year ago) I
  even reinstalled the system. However, after some time, it got slow
  again.

Only after this vague and undetailed description, the reply said that the reason would most probably be a hardware defect and that I should send the device in to be repaired.

How should I continue my analysis? Is the support’s assessment reasonable?

Update

Recently, a new app was added to the PlayStore concerning exactly one of my desired analysis:

Samsung Galaxy S4 only boots for 5 seconds, then dies
Yesterday I was using my phone, and suddenly it shut off. I tried the power button, but it wouldn't turn on again. I then took the battery out, and put it back in. Immediately, the phone vibrated, and displayed the Samsung Galaxy splash screen (this happened without me pressing the power button). After about 5 seconds, it shuts off, and I have to start the process over again. I tried booting in safe mode, and recovery mode, and the same thing happened. Interestingly, If I take the battery out, plug the phone in, then put the battery back in, the phone doesn't automatically start, but it still doesn't boot either. I tried changing the battery, but that didn't seem to make a difference. Initially I thought it might be something wrong with the power key, however, I would expect that if that were the case, it should be constantly restarting, not shutting off and staying off.

What could possibly be causing this? Is this more likely hardware or software, and is there any way to fix it that isn't just replacing it?

Add repeating tasks using stock calendar

Is it possible to have repeating tasks using the stock calender program?

Sometimes I have a task I want to show up each day for a month or something, but I don't want to have to stick with a photocopy machine and handwriting a task list when I have a Galaxy Note 3, running android 4.4.2 kitkat. I don't want to have to root and use questionable programs, just stock android. However, I don't mind, but would really rather avoid, doing something on a computer such as a Perl script and then syncing with wifi or or pushing through usb. I would think that the calendar program would have this feature, but I can't find it anywhere.

The event-type in the calender program can handle repeating events, but not task-type. Events just fill up blocks of time, I want the ability to check off a task, so events wont work.


问:
How to update/upgrade any phone to Android 4.4
Variations on this question appear to be a common unanswered question; often they have a comment or two that I don't understand. I'm hoping someone can answer with some general background information, the concepts.

E.g. I see reference to "rooting". Do I need to root a phone before I can upgrade it? I've had previous Android phones that got auto-updated (either by the carrier or manufacturer: I just find a message that says: "a new update has been downloaded, click here to install"), and I didn't need to root them.

E.g. Can any smartphone be upgraded to Android 4.4? If not why not? And why might a manufacturer not want users to update their phones? Are some manufacturers more open to having phones updated, and some not? Does anyone keep a list of "upgrade-hostile" manufacturers?

E.g. does the phone being sim-locked (to a specific carrier) matter?

I'm not going to say what my phone is because that will distract from the more general answers I'm after.

Is there an way to access a shared (networked) scanner on android?
I recently purchased a networked multifunction machine, and I was excited about its ability to scan via handheld devices using Epson's iPrint. Since I'm keeping the device in a different room from my computer, scanning via my tablet seemed much more useful than running from room to room, making adjustments.

However, I found Epson's android scanning app to be a bit... simplistic. It only scans preset document sizes, at preset resolutions, and only to jpeg or pdf, no lossless formats like png or tiff. I searched for alternative apps, and only found manufacturer specific options. My searching was complicated due to all the "scanning" apps that use the phone's camera, and scanning tools for network security.

So, my question is, does anyone know of any way to access shared, networked scanners and use the more advanced features that you see on desktops?

How do I prevent a bluetooth headset from muting when it hears sound
I have a Plantronics M50 headset, which works wonderfully on my Android 4.0.4 Sony Xperia Ion LT28at.  However, it mutes its output anytime it detects a loud enough sound.  If I type during a business call the incoming signal becomes choppy, and high wind sometimes causes callers to disappear completely for seconds at a time.

I have no other headset to test whether this is due to Android or the device, though I have tested with another Plantronics M50 with the same result.  I assume the headset is a simple receiver/transmitter, and so assume that this is probably a setting in Android, but I don't know for sure.

How to automate post install setup
I've noticed recently that i spend quite a bit of time setting up various settings after a clean ROM install. I was wondering how could i automate this post install hassle.

Specificly im talking about CyanogenMod 11-M9 and Android 4.4.4.

I know the settings are stored somewhere when i change system settings but im not sure where exactly. And what are the possible solutions?

If the settings are stored in human-readabale text files then maybe it's possible to create update.zip that i can flash in recovery and that updates the nessesary files with my settings?
Or perhaps there is a way to create a script that i can run post install when i have set up preliminary things?

Or maybe i should just build my own ROM from sources that already includes my customized setting (tho this is problably too complex at first).

To clarify - im talking about system settings starting from setting up google account and ending in custom alarms. 3rd party app settings i can restore easily with Titanium Backup but it doesent seem TB is able to restore system settings (possibly because system is running at the time?).

I would be greateful for any tips on how to accomplish this.

Disable the sd card emulation and use only the external sd card?
My Mother has a Samsung tablet, which is not rooted.

Is it possible to clear-default of an app using an ADB command?
Not sure if that's the place to ask this (maybe stackOverflow is better), but here we go:

Background

There are plenty of possible commands that you can perform by using ADB.
I use many of them on my tiny app-manager alternative app.

The problem

I can't find a way to clears the default of a specified app.

I mean the clearing of the app as the default one to handle some actions, as being shown on the "app-info" (AKA "manage-app") screen.

What I've tried

In the past, it seems that it was possible by having a certain permission and some API commands, but it's no longer possible.

A possible workaround would be to disable&enable the app, but that causes weird things to happen on some other apps, for example launchers will remove the app's icon when it becomes disabled.

I've also noticed a file on :

```<code>/data/system/users/0/package-restrictions.xml
</code>```

that has some xml tags that include apps, and when I clear-default of an app, it is gone from this file. I don't think that playing with this file would be a good workaround, as things can change over time, and I don't even know if changing it will do anything, especially not in the current session.

The question

If there is no such a command?

Is there any way to do it using root?

How to configure VPN using pcf profile and custom certificate
I want to connect the VPN of my university with my Android device.

My university provides a .pem certificate, a .pcf profile and instructions how to set up the vpn connection under a "normal" GNU/Linux distribution - on Arch Linux this works perfectly.

On my Android phone I tried the built-in connection manager and the "anyconnect ics+" app by Cisco, but I'm stuck:

Basically I can't import the profile: the built-in app doesn't provide any form for this; the Cisco app only allows xml-profiles (which is strange as I want to use a Cisco technology...).

The Cisco client doesn't even allow me to import the certificate: when importing it asks for a password, but I don't know why. For the built-in app I could convert the .pem to a .crt file (issuing the command openssl x509 -inform PEM -outform DER -in chain-dtag-dfn-uni.pem -out chain-dtag-dfn-uni.crt) and import the converted certificate.

Do you know other ways or other apps that allow me to connect to the VPN?

Adding an extra keyboard button for switching to rarely used languages?
I type in the following 3 languages:

Language A - 55% of the time

Language B - 40% of the time

Language C - 5%  of the time

The usual solution would be to have all three languages installed, however it is quite annoying to have to switch over Language C each time I swap back and forth between A and B.

Is there some sort of solution that would allow me to either have an extra button for language C or switch to language C using a special key combination?

I'm using Nexus 4/Android 4.4.

Thank you.

Zagg Folio Tab 4 no longer connects to my Galaxy Tab 3

Android won't boot after accidentally uninstalling a system app
My android version is 4.2.2 so while I was installing an app on the system using Moborobo I think I might have accidentally removed a system app.
I have checked all over the internet and I am pretty sure I don't have access to my original ROM that comes with the device. Even Clockworkmod for my device isn't available so I hadn't made any backup.
I have tried to factory reset using the recovery option that came with the phone and it boots fine. When I power it off or reboot it won't start until I do another factory reset. Where do I start to fix this? I have connected the phone to ADT but I can't get the logcat to pause so that I can post the output here. Meanwhile if there is anything I can do let me know as I try to get the logcat output</p>

Samsung Ace 3 - S7270 - Wifi and recovery mode problem
My Samsung Ace 3 does not detect any Wifi networks, and it cannot connect to Kies.

My wifi network is fine, and there are lots of wifi networks in the area, but my SGA3 does not detect any of them (my other phone does).

Kies does not detect my phone. It does detect other phones but not this one (same USB cable, same usb port,..).

I can access the android file system using windows explorer (phone + sd card).

I tried to go to download mode (Volume Up, Home, power off): it just shows an Android logo with an open chest with a keyboard. It stays that way for few minutes and the it proceeds to normal booting. (I tried pressing few buttons but it didn't work)

I went to Factory mode (Volume down, Home, power off): it had a bunch of tests I can run, when I ran the Wifi test it gives me a "blank" mac address:

How to revert phone to state before last-but-one factory reset?
Two days ago I found my non-rooted Nexus 5 in my pocket asking me which language I like. It looks like it has been factory-reset, and I suppose that one of my corporate accounts has reacted on accidental lock-screen PIN input. (Having tried it today, I can't exactly understand how that was possible, but let's assume that's just the case.)

The problem (which I was not aware of that it IS a problem) is that I was offline (roaming) when I noticed. I needed my phone, so I skipped the Wifi setup because my phone just told me it could not verify my software was up to date. I'm on 4.4.4, so I knew it was up to date.

Then, even after logging in to Gmail, Play Store etc., I was unable to get the Google backup restored. Wifi passwords, apps, home screen layout, app settings, that kind of stuff. I suspected that the only possibility to restore a backup is when the phone is first turned on after a reset and I might have lost that opportunity. So I did another factory reset (this time near my Wifi) and voilà, I could login and chose to restore the backup.

BUT: this restore restored what I had installed after the first factory reset. Indeed, the dashboard says this:

```<code>No carrier
Last activity seen on: Sep 1, 2014
Registered date: Jul 10, 2014

LGE Nexus 5 o2
IMEI: xxx
Registered date: Sep 3, 2014
</code>```

So there's two devices now, one the "old" from before the first reset (on Sep 1), and another "new" one which was probably created by resetting my phone without restoring the backup (on Sep 1), refreshed by my most recent reset with restoring the backup (on Sep 3).

That was a long intro for a short question: Is there any way to revert my phone to the state stored under that old "No carrier" entry? Unfortunately, I have found neither a way to delete one of these backups (for example, the new one) nor a way to even look at the data.

问:
Nexus5 identified as Media Player (Device), instead of Storage Drive, Windows 7
I've had the Nexus 5 for a few months, and exchange files between my PC and the phone using the USB cable frequently. I also charge the phone using the USB connected to my PC. Usually, the window pops up asking what I want to do with the device, which I ignore if I'm charging, or select Explore if I'm file-transferring. About a week or so ago, I noticed that instead of options, there were NO options on the pop-up, and just a "Do Selected every time" or whatever. But no options below. Until last night, I haven't had the need to transfer files, so I ignored it.

So last night, I closed the popup and looked in My Computer, and the normal Nexus 5 was nonexistent as a Drive. There was a Safely remove Hardware icon, so I selected it and chose Open Devices and Printers. There was my Nexus 5, under Devices, identified as Media Player under Properties. My only other options on right-click are Eject, Create Shortcut, and Troubleshoot.

I can no longer access my files. I rebooted both, checked the settings on the phone, called T-Mobile, then Google, then Iolo, my antivirus and whatever-else-it-does doer, to no avail. The kicker is, I plugged it into a buddy's computer hours earlier to retrieve a file, and it connected as storage immediately. I tried on my wife's laptop, and it does the same. So something had to have changed inadvertently on my PC, and I'm sure it's something simple, but it's beyond me.

Editing files with Linux Deploy
I have a 2013 Nexus 7 that I'm trying to use to replace my laptop. I recently installed Linux Deploy and am running the testing distribution of Debian on the device. I've installed all my productivity suite, and things are so close to perfect. I have one small problem I'm hoping you can help with.

I have a few files, such as emacs org-mode agenda files, that I sync with Dropbox. I recently installed DropSync to download those files and keep them up to date on my device. DropSync allows 2-way synchronization, so editing them on my device should update them in Dropbox. I've set up a symlink to my DropSync'd folders to make it easier to access those files. Currently they are all stored in /storage/emulated/0/Dropbox, with the symlink in my home directory created with ln -s /mnt/0/Dropbox, because /mnt/0 is the mount point for /storage/emulated/0 from my Android fs.

The problem comes when I try to edit the files. Unless I use the sudo command in my Debian install, I only have read access to the files. When I run ls -l on a directory, I get the following:

```<code>-rw-rw----. 1 root aid_sdcard_r   0 Sep  3 12:46 filename.example
-rw-rw----. 1 root aid_sdcard_r 242 Sep  3 12:46 filename2.example
</code>```

I've tried running chmod, but none of the permissions seem to change. is there a way I can permanently change the file permissions in directories I am syncing, so that I don't have to use sudo to edit the files?

The results of mount for the mount point of /storage/emulated/0 are:

```<code>/dev/loop15 on / type ext4 (rw,seclabel,relatime)
proc on /proc type proc (rw,relatime)
sys on /sys type sysfs (rw,seclabel,relatime)
selinuxfs on /sys/fs/selinux (ro,relatime)
tmpfs on /dev type tmpfs (rw,seclabel,nosuid,relatime,mod=755)
devpts on /dev/pts type devpts (rw,seclabel,relatime,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw,seclabel,relatime)
/dev/fuse on /mnt/0 type fuse (rw,nosuid,nodev,relatime,user_id=1023,group_id=1023,default_permissions,allow_other)
</code>```

Results of mount in Android Terminal Emulator are extremely long. The one referring to /storage/emulated/0 is

```<code>/dev/fuse  /storage/emulated/0  fuse  rw,nosuid,nodev,relatime,user_id=1023,group_id=1023,default_permissions,allow_other 0 0
</code>```

Is there a USB only file sync tool?
I've been looking for a tool that will sync to/from an android device running Android 4.4.4 - so it's using MTP when I connect to my computer (running Windows 7) through a USB connection.

There are various options that require a drive letter, but MTP doesn't have those.

There are various options that use wi-fi and a through-the-internet solution, but I don't want to use the internet for this, I can copy files by hand so there must be SOME way of syncing.  Also, I want to use it with pretty big files so I was hoping there would be something that used file deltas. If I wanted to go through the net I would consider RSync, but I don't want to.

Ideally I would prefer something free and open source, but I can't find anything at -all-... Am I using the wrong search terms? (android, sync, usb, mtp, "open source", mix as desired.)  There are lots of similar questions on here, but as far as I can see they're all answered with a wi-fi sync tool instead of something USB specific.

  HTC Desire low on internal storage, I'm clueless

I need a good and solid way to find large things which are taking up lots of phone internal memory. My phone really just stops working, sync-wise, when I'm running low on space, which seems to be all the time.

I'm running LeeDroid and have set my default install application as the SD card, but it seems that I can still fill up my internal phone storage quickly. I did try the App2SD+ setup, but couldn't seem to partition my card properly.

So does anyone have any good tips? At the moment I'm clearing Maps data and Browser cache, but now that's gone also. Do apps on the SD card still put data on the phone? Or do I just need to make more effort partitioning my SD card to get App2SD working?

Something which created a list or pie chart or both of internal space with links to clear data or uninstall would be idea.

Cannot access google after SIM card change
I am currently on a vacation in Portugal and bought a local sim card for a Samsung Galaxy S4 with stock ROM. Now I cannot access any google services anymore. The rest of the internet works fine but any site using google's cdn fails to load. Android of course is almost impossible to use. Interestingly enough it only affects google.com, other google domains work fine.

I did originally receive an email from google claiming a suspicious login. I verified that it was me on their security page on another phone. I tried resetting the dns cache, change the dns servers, the google unlock captcha, ... nothing works. It works fine when I log in via Wi-Fi. If I share the connection with a tablet that tablet can access anything just fine. Deleting and recreating the google account on the phone also does nothing.

Google mail servers not allowing email setup
We have a a handful of people helping us configure android phones.  We'll get contracts for 500, 700, 1000 phones for example.

Part of the configuration is setting up a gmail account on each phone.  We started having issues not being able to connect to the Google servers to complete the setup.

Example:

5 people setting up phones About 4 - 5 minutes per phone

Each phone has their own individual Gmail account

In the email setup section.  We’ll enter the account that is then successfully verified by google as being available.

Fill out the captcha on the screen submit.

The following screen states “Couldn’t sign in.  There was a problem communicating with Google servers.  Try again later.”

When this happens to one - it happens to ALL the phones

If we move the phones off the building wifi to another wifi say a cell phone hot spot.  And run thru the same procedure on the same phone the email account is completed and set up.

If we come in the next day we just repeat the above.

Our assumption is Google is seeing a large number of accounts being setup from our WAN IP, but we can’t change that ip.  Is there any other work around that anybody can think of?

问:
Is the analog clock widget somehow tied into the unlock screen?
I've encountered something bizarre on my phone which I think is just an innocent side effect, but I wanted to make sure that it wasn't indicative of something malicious.

From time to time, right after I unlock the phone, the LastPass prompt pops up and asks me if I want to input my master password in order for it to autofill the password for "Clock Widget."  I don't use the clock widget on the lock screen, though.

I don't ever provide it the password, but initially I was concerned that there might be a program masking itself as the clock widget.  Since the prompt is so closely correlated with the unlocking, I have to believe, though, that LastPass is offering to fill in my unlock code, even though it can't.

Is the clock widget somehow associated with the part of the OS that controls the unlocking of the device?  Is there any legitimate reason why it would ask for a password?

I have an LG G2 running 4.4.2 and I have scanned the device with Malwarebytes Anti-Malware as well as Kaspersky and I haven't found anything at all with either.

I wasn't able to grab a screenshot before the LastPass prompt disappeared, unfortunately.

Why does my sound randomly stop working?
I have a rather old Motorola Droid Razr Maxx.  A week or so ago it was having some serious problems which rendered it fairly useless, so I installed CyanogenMod on it.

Since then, sound will randomly completely stop from all sources.  Various apps, music, even phone calls.  Nada.

I'm fairly certain this is a software issue as the sound worked fine before flashing CyanogenMod and a reboot temporarily fixes the problem (and is so far the only solution I've found).

I'm fairly sure it doesn't have to do with the headphone state as neither speaker nor headphones works when the sound is broken, yet both work immediately after a reboot.

Constantly rebooting my phone so I can actually receive calls is rather sub-optimal.  What can I do?

Google Play apps, login in someone else's account
I have this weird problem on my tablet. Most of the time I can download a game in Google Play and create a game account or just play normally with a local save. But there's a long list of games I just can't play because after installing and starting it, it literally logs in someone else's game.

For example Simpsons Tap Out, Summoners War or pretty much any town building game or else, there's already an account created, no password needed to enter and I can clearly see its someone playing. I don't know how to explain better, I just avoid playing it because it's not my game, it's not really fair to that person and he can just keep playing over me or delete his account someway.

In these apps there is almost no way to create an ingame account with a password, I thought someone was using my email, tried with a different one (on the same device) and still same results. How come I can enter someone's account without a password or ID? This tablet was bought new, nobody uses it except me, I shouldn't be able to just get in people's game and not able to even create one for me.

It's a low cost tablet from Prixton, model T9100, really cheap stuff but gets the job done (just this problem bugging me). I factory reseted it, tried different emails, still does it. is there something I can do to avoid this situation? Thanks

How to make Hangouts automatically fallback to sms when no data connection?
I use the latest Hangouts version (the one rolled out a few days ago, which now supports voice calls) on a Nexus 5. I have set Hangouts as my default messaging app. In the past the following behavior was possible: when I was sending a message to a contact on Hangouts, if either I or they didn't have an internet connection, Hangouts would automatically send it as sms. Now it doesn't behave like this.
Currently, if the sender has no internet it would show status sending under the text of the message forever. But if the receiver has no internet, it would show the message as sent on the device of the sender, giving you no clue, that the other party hasn't actually received the message. Is there a way to revert to the old behavior (similar to iMessage on iPhone) - if any of the two doesn't have an internet connection - use sms?

Android wifi hotspot shows up no matter where I am
I'm having some odd behavior on my Galaxy S3. Suddenly, there's another Wi-Fi hotspot showing up, which shouldn't be weird, except it shows up literally everywhere I go.

I work in Austin, but live an hour east of the city. The same Wi-Fi SSID is showing up not only at both locations, but on the entirety of the drive between the two. It's not a network I've ever seen or connected to before, and it doesn't give me the option to forget the network.

It's not showing a signal strong enough to connect (0 bars), but it's always showing up as:

```<code>sabasissy - Secured (WPS available)
</code>```

I can see my home network just fine, and my neighbors. I can walk out into the hills behind my house, that were destroyed by a wildfire 3 years ago, with literally nothing around me for a half-mile radius, and still, this network shows up.

I don't think it's a legit hotspot, as my laptop shows only my and my neighbor's Wi-Fi, with even stronger signals than the phone, but doesn't see this new hotspot at all.

Probably also not a Bells of St. John scenario, either. Could this be an indication of some sort of infection/rootkit on my phone? Where does Android store the list of available connections between scans, and is it possible that something's just written to that file and is keeping it from being deleted?

Any help is appreciated.

Update: Ran WiFi Analyzer all the way from home to work this morning, watching as it picked up access points along the way. The one in question never wavered, always showing up -90 dBm. Played with some of the options when I got to work, and noticed that the AP's MAC address is all zeroes.

Is there a way for a power-user to access these files? Any unusual methods welcome.

So far it sounds like: Step 1 - root. Step 2 - ?, Step 3 - profit!

How do I know whether my HTC One m8 has quick charge 2.0 capacity yet?
Although the HTC One m8 has a Qualcomm 801 processor, the Quick Charge 2.0 capacities has been disabled and the charger that the M8 comes with is a Quick Charge 1.0 one.

Apparently, some markets have had a firmware update that have enabled this feature.

I just got my phone so I was wondering, how do I know whether my m8 supports QC2.0?

I'm thinking about buying one but don't want to buy it if it is turns out my device isn't supported yet.

How can I fix a bootloop on my Nexus 5 running Cyanogenmod 11?
I've been running the Cyanogenmod nightlies on my device. If I remember correctly, I was running the nightly from 2014-09-07 (7th of September).

Yesterday I flashed the M10 release without totally understanding what it was all about. I thought it was newer than the nightly but apparently not.

My phone is now stuck in a bootloop. It boots all the way to the home-screen for split second and the whole process repeats all over again.

I've messed this up real bad and don't want to lose all my data. Is there a way I can fix this? Can i just side-load the latest nightly and flash it onto the device or do I flash the same nightly that I was running?

This sort of question has been asked so many times before but I couldn't find one that explains how to resolve this. Thank you.

How to find custom ROMs for rare android devices?
I've recently bought a Tesla H7 tablet. Since it's a 'local' brand, I don't expect to see any updates, and I was wandering how could I find some other (cyanogen, or other) ROMs to update the software myself (currently, it's 4.2.2).

Do I search for roms that match the CPU/resolution/ram/... does it need to match every specification, or only in part?

Unable to see newly added contacts on Viber for Nexus 7 LTE
As title says, I've been looking for a solution to this issue but it seems like its something to do with Viber itself. To describe the issue, I'm using a Nexus 7 LTE version with KitKat 4.4.3. It works perfectly on the device but neither can I search contacts nor see a newly added contact (before the last update) under Viber when added through Google's default "People" app.

And soon after the latest update I could search for the contacts but not the newly added contacts been seen though the user is a Viber user.

Quite amazing is that when I switch on DATA on my mobile (which also has the same Viber number configured) & sync the contacts which then the new contact start to appear on Viber under both Nexus & mobile device.

I don't know whether this is a bug with Viber for Nexus devices as I've not seen any solutions to this so far. An output or advise on this will be great!

Thank you in advance.

Can I pull data off of a Moto 360 (smart watch) using ADB?
I am a complete beginner to the world of Android, but I am also an intrepid forensics examiner. I have been given the opportunity to conduct research into pulling data from certain wearables, namely Android watches. A colleague of mine suggested I examine the Moto 360 smart watch, but my initial research into the methods of conducting that examination has fallen flat.

Can ADB (or another tool) extract valuable data from this specific smart watch? If so,       how?

If there are no available data extraction techniques at this time, should I shift my focus to another wearable?

How to reduce the quality of streaming on Galaxy S4
I recently upgraded from Galaxy S1 (Android 2.3.5) to S4 (SGH-I337M with Android 4.4.2)

The thing is before I couldn't have the Chrome browser because was not compatible and my YouTube app played videos just in HQ.

But now my S4 plays streaming in HD (720p). I set the option to see videos in HD (YouTube) only on WI-FI but even though I did this, my data plan is being devoured.
When I see streaming from pages in Chrome, they are also spending my data plan.

I know this thanks to the data usage application in android (Apps > Settings > Data usage) and match exactly with my internet provider consumption plan.

How can I do to reduce the streaming quality in general on my S4 in order to reduce the consumption of my data plan.

I tried to ask the same thing in google but mostly all the pages advice to do the opposite, I mean... how to increase the video quality on android.

It doesn't bother me to see videos in HQ like before.

Install ROM to save android samsung galaxy mini GT-S5570
I rooted this device about a year ago and attempted to install a rom however as I failed to find that much information on how to do it I ended up going into the stock recovery mode and attempting to install a zip file I had downloaded. I did this by choosing "apply update from sdcard".

Obviously this is completely wrong and my phone is now always stuck in a bootloop. It also seems I have filled up the entire memory of bogus files as when I tested to install a file through recovery mode I get the error "No space left on device".

My question is if there is any way I can install some ROM(or anything) so that I can use this phone again. It seems I can't do this through the phone as I don't have a custom recovery so if I can do anything from my mac that would be great.

Move Apps from Internal to SD--Android 4.1.2, LGE Optimus F3
For those who don't know, the Optimus F3 has only, like, 2gb of internal space. And because Google's Nexus phones don't have SD card slots for some really weird reason, they decided to just pull the function from Android entirely for a few versions. This includes 4.1.2, the version on my phone.

I have gone through the trouble of rooting my phone and downloading numerous programs to help me hack into this hunk of junk, but I can't for the life of me figure out what to do.

And yes, I have tried App2SD's linking thing, and it doesn't work.

I am 99% sure that you can simply move apps from internal to external storage using the SDK and/or command line or something like that, but I have NO idea how and I've looked all over and found nothing that can really help much.

Could someone PLEASE be so kind as to help this poor guy out and actually be able to use that 8gb SD card I got just for this reason? I have struggled and finally gotten Eclipse working, but have NO idea what to do with it, or if I need it at all. Just please, I'm begging you, HELP!!

Cyanogenmod unlocked phone requires network unlock code
I have a Sony Ericsson Xperia Arc that I installed Cyanogenmod (v. 9.1.0-anzu).
The phone is not locked to a specific network as a) the danish operator where I bought the phone does not do this and b) I recently changed operator without any hassle.

I now have two possible related problems.

A couple of times per day, the sim card needs unlocking. As in when I unlock the phone, it requests the PIN code. Not a major issue, but a nuisance.

After entering the PIN code, the phone requests the network unlock code, to which I press the "Cancel"-button.

I've been searching the googles, but most hits reply that I should restore ROM to stock, get the network unlock code and unlock the phone. But this seems a bit ridicules, as the phone isn't locked.

Low Quality Contact Photos on "Card" in Android Wear
I own a Moto360. I use Google Hangouts as my default messaging app on my Nexus 5. When the "card" shows up on my smartwatch, the contact image on it is low resolution. It is noticeably blurry.

Google Hangouts and Instagram both have low quality contact images showing up on my watch.

A lack of sim card in my android device crashing my apps? Why?
A weird problem I observed with my Micromax A116, android version 4.2.1.

From the day I bought it, 8 months back, I have used both the sim slots.
But the internal earphones were damaged & I couldn't listen to calls, so I bought a low-end Nokia phone & removed both sim cards from the Micromax phone.

I was using the android phone just for internet through a wifi connection. For 2 days, it was fine ie apps worked as usual. Then on the 3rd day, Twitter app started crashing while in use, often. Then the next day, Pocket stared crashing & relaunching. I updated both the apps, but the
problem persisted. Then the inbuilt Galary app, facebook followed.

I guessed it may be a sim card issue. So reinserted one sim. The phone was back to
normal with no more crashes. After a few days , I again removed the sim card & used the apps, the same problem returned.

So the question is, was my guess correct that a lack of sim card was crashing my apps? If yes, then why is that so?

Restore disappeared apps on SD linked with Link2SD?
At some point Link2SD told me that it needed to regenerate the mount script, did it and offered a fast reboot option. This caused an endless boot loop which I escaped by

checking the SD card (partitions: fat32, ext4, swap) in gparted on a PC. It turned out, it had some severe error which could be fixed. This is probably the reason for the need to regenerate the mount script. And by

moving the folder dalvik-cache on the second partition temporarily to the PC, booting the Android device, shutting it down, moving dalvik-cache on the device again (otherwise it wouldn't break out of the boot loop)

After rebooting > 70 % of my apps were gone from the app menu. Their icons are still on the five main screens. The content of the SD card didn't change, so I believe there's high change to restore the apps by fixing Link2SD. I'd like to know how to do that.

问:
Cannot hear audio from other side of phonecalls or voicemails
When I make a phone call (this includes to voicemail), I cannot hear the other party and the other party cannot hear me.

The problem is isolated to calling. When I'm having this problem (or more precisely, when I can replicate this problem), the following behavior is consistent:

entering numbers with the dialpad produces the usual audible beep,

the Sound Recorder app on my phone works fine,

any apps that use the speakers work fine (e.g. Apollo, ES File Explorer audio service).

Rebooting my phone temporarily resolves the problem, which seems to recur an indefinite number of hours following a reboot. I have been unable to identify any specific app or service which causes this problem.

(Unrelated to the problem, but still relevant - CM hangs when I attempt to boot into safe mode, which is only resolveable by popping the battery and booting back up normally, at which point all configured widgets sans lock-screen Torch have been removed - these reboots also fix the problem - so tl;dr: being unable to boot into safe mode, I am unable to determine whether a particular third-party app/service is the cause of this problem).

I have a T-Mobile SII (Hercules SGH-T989) running CM 10.2.0-hercules (corresponds to Android 4.3.1, baseband version T989UVMC6 - I assume this is the radio). I have no call recording apps - the closest thing I have is the Dialer app, which (it seems) does not handle any calling, and simply hooks into the stock Phone app to make calls.

This began a number of months after I upgraded to CM 10.2.0-hercules from 10.0, so I highly doubt that CM is the problem here.

SDCard permission issue
I have a Samsung S3 which I have installed Cyanogenmod on with a view to carry out some procedures with root permissions.

At the minute I am trying to create a .img file of the userdata memory block using the DD command in the adb shell. I have a 32GB SD card which initially was formatted as FAT32 and therefore failed once the .img file reached 4GB. I expected as much but I wanted to check things were going ok before I reformatted the card.

I then formatted the SDCard as ext4 using gparted. I noticed on my ubuntu machine that the card had root ownership so I changed that to user and I can read and write files in nautilus fine.

Switching back to the adb shell, I carried out the same command as below (which is what I previously used when it was formatted as FAT32) and I get a permission error. Its driving me insane, I've tried chown'ing and chmod'ing till the cows come home and still nothing working.

#error message is

I have enabled Auto Link on Link2SD, yet whenever Android tries to updates any linked app, it ends up deleting it. How can I fix it? If the problem is with Link2SD then what alternative apps are available?

Permanently disabling Galaxy S3's calling and SMS
I've procured myself a Galaxy S3 and I intend to mess with it.

I'd like to have a phone that runs one app and one app only (mine).

I want to disable calling, texting, app installs. Come to think of it, I still want to be able to receive texts, but not send them.

Removing the base apps isn't necessary as long as they're made non-functional in some other way like crashing on startup or something. Outgoing calls or picking up incoming calls is a no-no.

What's the best way to go about disabling these features?

Here's an "artist's" rendition of what I want to see ideally:

Asus Transformer Tab tf300t stuck on asus screen. No ADB, no fastboot, no recovery, no os
I'm very happy with cm11 on my Galaxy s3 so i wanted to try it on my tf300t.
First i unlocked the bootloader which i succeeded in doing.
Then i flashed clockworkmod recovery via adb.
However, when i tried to enter the recovery, it didn't work. So i tried a couple of more times by turning the tablet off and re-trying to enter recovery.

That's when it all got terrible. While is was in fastboot mode (i had the three options of RCK, android and wipe) and i was trying to select "Android" with volume down but i pressed on too many and got "Wipe data" selected. Couldn't go back. And since then my device is stuck on the ASUS logo. Now it looks just like this:
http://srv1.jpg.co.il/7/52e6c1d38d07a.jpg http://srv1.jpg.co.il/7/52e6c1d38d07a.jpg

And everytime i try to restart it just goes to this screen. I even tried manually resetting it with a paperclip. So now i'm kinda hopeless.

Please Help me!

Customer claims our app trashed her phone
I'm in receipt of a complaint that the android mobile app my company provides has trashed a customer's android phone to the extent that it is now only capable of making phone calls. No sms. No internet. No email. No other apps open.

The phone in question is a Samsung Galaxy S3, android version unknown. Our app is a front end to a web service that posts messages, photos and videos on something like a forum software, used for market research. It shows a question, and the user can respond by typing text, taking a picture or recording a video. It does hence request access to user photos and videos, and it makes use of their location services if turned on (essentially so we can show the researcher where they were when they were commenting on the products in the research study)

The complaint, as I understand it, is that the app was installed, run, it showed the first question and then crashed. Since then, the user has no emails, no sms messages, cannot use the internet or any other app, cannot get into the phone settings, launch anything or communicate in any way other than opening the phone app and make a call.

Our client (the person who introduced the customer) is demanding I call this customer and sort the problem out over the phone but I'm unable to because I cannot even imagine how the phone comes to be in the state it is claimed to be. Essentially I've no idea what the problem might be with the phone, no idea how I'd investigate it and no idea how I'd resolve it. The customer has no technical ability at all and claims not to have any other internet capable device that I could use to even get a video of the phone in operation..

Can anyone out there, from the symptoms described (and sorry it's not a great description; it's literally all I have) suggest anything that might have gone wrong - defective memory chips? - that would manifest as an Android device becoming nearly totally unusable?

If the claimed symptoms are true, I'm certain that the phone has some other problem and it's pure coincidence that it manifest since installing our app, but the customer is adamant it must be our fault because our app was the last thing she installed before it all failed. I know for a fact that our app is installed on thousands of android phones and works well. I also know that it contains no code capable of rummaging through the phone's file system and trashing stuff, if such a thing is even possible on Android? (Are apps sandboxed? Checked by Google to ensure they have no malicious code inside?)

Thanks for any comments or insight you can offer

Significance of Internal SD Card in Micromax phone
I have brought the Micromax A106 phone that has 8GB ROM. When I see the internals of the phone, the internal memory of the phone is partitioned in two ways - 0.98 GB as Phone Memory while 5.85 GB as Internal SD Card Memory.

All the apps, phone contacts etc are getting stored in Phone Memory (0.98 GB partitioned) due to which the phone memory is getting a low space and whenever I install any app from Play Store, I'm getting "Error: Cannot install due to insufficient space"

However, when I installed the SD Card, I was able to install/move the apps to External SD partition slot since the phone contains Android 4.4 Kitkat operating system.

How can I make use of the Internal SD Card Memory so that my Phone memory is not getting full?

How to setup Microsoft Exchange on Android? [No certificates found error]
I'm using a Nexus 5 running Android 4.4.4, and when I try to setup my company's email through the Email Android app I get the following error.

No certificates found

The app Exchange Services has requested a certificate. Choosing a certificate will let the app use this identity with servers now and in the future.

You can install certificates from a PKCS#12 file with a .pfx or a .p12 extension located in external storage.

And there's an Install button to choose a file from my SD card.

The thing is, I don't know what this file is nor where to get it. And I don't even know why should I provide it, since I've done this same configuration before in older smartphones I had. Did someone experience the same issue? How would I be able to solve it?

Is there anyway to for the app list to be sorted by applications' trimmed names?

E.g. in the screenshot below, the application " Flashlight" appears first because it contains the space at the beginning. I would like to avoid that.

Are there any bugs associated with the kernel?

My phone is not rooted and is running firmware version 2.2.1 and kernel version 2.6.32.9.

Why can't I get Dolby Digital sound from Android TV box linked to Sony AVR?
I have just bought my 1st Android TV box (it's a Chinese CS918 rk3188 model) and since it has SPDIF/optical out I hooked that to my Sony AVR's optical input and set the device manager in the Android TV box to enable "passthrough". I played a video which has 5.1 Dolby Digital sound using MX Player, but alas, even though all of the notification Dolby Digital display lit up on my Sony AVR no sound came out of the speakers!

I got sound straight away when I switched to PCM sound but I am very disappointed as I prefer Dolby Digital. What can I do to get DD sound or does my specific model of Android TV box not support DD sound

Here is a screen shot of my sound devices manager settings:

alarm clock app with notification on lock screen
In the past active alarms from the default app showed up on the lock screen (time and date). This feature seems to be gone in 4.1.2. Does it work in later versions of Android? Can it be done somehow with an external app?</p>
