Text Messages Sporatically Get Stuck In Unsent State On Droid 3
I have been having this issue for a long time on my rooted Droid 3 using the ROM it came with and this happens daily with relevant logs being left or any clear trigger.

Basically what happens, and it tends to happen after the phone has been on for a few hours, I will send a message, usually with Handcent SMS (though I've experimented and tried other apps including the stock SMS, still happens) and occassionally a text will get stuck.

Now one of two things generally will happen. Either it'll sit "sending" for about 5 minutes before finally failing. This acts like a text bottle neck, because if, say, I have a multi-page text being sent, the other queued messages will send instantly when the initial text fails.

The other thing is that the text message will just sit sending indefinitely until I notice it hasn't sent and I delete it manually. If I resend it, sometimes those subsequent attempts will also hang.

And once this starts happening, it will continue to happen until I restart my phone, resulting in my restarting my phone several times a day.

An interesting observation that could help diagnose is the issue is once when I observed this happening, I open up a SQLite debug app and when I try to open up the mmssms.db file, it cannot read the file, which makes me think, perhaps the file is locked which is why the SMS process cannot commit the change to the database. Just an idea; don't know if that's at all related.

Edit: This does seem to happen more often after heavy usage, say playing a game. Could it be that' some sort of SMS-handling daemon gets killed, perhaps?

What is in Nova's Google folder?
I just installed Nova launcher on my Android phone. When I installed it it created a Google folder with all my Google Apps in it. I accidentally deleted, but I want it back.

Can anyone tell me what apps were in it?

Xperia V New SD Card, can't make it recognize it as external
SEARCHED FIRST, WANT TO ASK MYSELF!

So I just bought a new Micro SDHC card, 32gb Samsung, placed it in the turned off phone, then turned it on, the sd card is recognized, but it doesn't appear in the Applciations directory in Settings as External Memory, and if I try to move some app to external memory, it only appears as Move to INternal memory, and if I click it it changes to Move to Phone.
With Root Explorer there are 2 sdcard folders, sdcard and sdcard1, also a folder storage which contains sdcard0, sdcard1 and usbdisk.
What can I do to make the phone recognize the sd card completely and not use emulated sd card anymore?

Email app displays messages in "Sent" by "From:" instead of "To:"
I configured my Email app to point to an existing Yahoo Mail account.

When I go into the Sent folder, I see that the Android-composed messages display the recipient (To:), but the older messages display the sender (From:)

I checked the headers on several messages. It seems that Email app is selecting first occurrence of "From:" or "To:".

So my older messages say...

From:
To:

...and the "From:" is displayed in the message list

The new messages I composed in Froyo have:

To:
From:

...and the "To:" is displayed in the message list.

Is this the expected behavior? I know that some things are different in mobile world, but classically, the "Sent" folder has been special cased to show who the message is being sent to, because that is the most useful information to display in this context.

Deleted stock browser browing history recovering and stock browser "opened tab" information
For some reasons, I cannot see my browsing history for a week (does Android stock browser automatically delete browsing histories?):

So, has my browsing histories been deleted? If so, is there any way to recover it?

Secondly, if stock browser crashed and opened tabs weren't recovered, is there any way to find out information either by trying to recover some file that contained the information (so, I guess android equivalent of Recuva) or anything else?

BTW, I use Android Ice Cream 4.0 and my stock browser does preserve tabs, except in some crashes (not all crashes close down tabs). I use LG Optimus LTE II.

Emulator takes forever to shutdown!
The title just says it all. My 3.3", Android 2.3.3 emulator (armeabi) boots averagely in 150 seconds on my Ubuntu 12.04, 64 bit system, with 2 GB DDR3 memory. However, sometimes when I tried shutting down using the power button provided in the emulator. I am made to wait indefinitely!

This doesn't hurt much, for I usually just close the emulator just like closing a window. However, I somehow can't reconcile the fact and need to know reason(s) why, in spite of booting fairly fast, shutting down takes ages! Does shutting down consume more resources than booting?!

问:
creating a pseudo sd card by partitioning the main drive of an android phone
It seems like it's possible to mount the SD card of rooted android phone on a PC while the phone is connected to the PC via USB. This would be great for me because I want to keep essential files saved on my phone, edit them from the PC when I need to and bring them with me wherever I go. Unfortunately, the phones I want the most (nexus 4, HTC one, HTC one x with 64gb) don't have SD cards. Is it possible (on a rooted phone with cyanogenmod) to partition the "HD" on a phone without an SD card and then use that partition as described above? (The format of the partition is not very important to me.)

Will the solution suggested here[1] make it possible to mount the .img file on the PC while the phone is connected via USB?

What are these numbers in the Data Usage and Battery Usage screen in Jellybean?
I went to my phone manufacturer the other day to get my phone upgraded to Jellybean 4.1.2 from ICS 4.0.4. Here's the thing, I know that upgrading doesn't take long but they said it will take an hour and they made good with that, so I'm at least worried on what they did with my phone for a full hour. Well, I forgot all about it when I noticed I have some numbers instead of app names on the battery usage screen. Worse, it appears they're using my data connection. Then I went to the data usage screen and more numbers showed. Should I be worried? I asked someone with a Jellybean phone and he said all he sees on his phone are app names. I don't want to register my card on the Play Store yet unless I'm sure my phone is safe. Is this happening on anyone else? What are those numbers?

Linux doesn't recognize Galaxy S 3
I've bought a Samsung Galaxy S 3 device today, but found out that I could not get my PC with Fedora 18 (Gnome 3) to recognize it (nothing happens when I plug it in).

As file transfer etc is essential to me, this renders my device pretty much useless (I don't have an SD card slot on my PC at the moment).

Android lets me choose how I connect though: as a "media device (MTP)" or a "camera (PTP)".

Is there a way to simply access the storage on my phone from a Linux machine?

It's pretty ironic because both my PC and my phone are actually running Linux, yet they can't communicate. For a large company like Google/Samsung there's pretty much no excuse for this, as Linux is quite popular nowadays, especially because Google already does most of its work on Linux.

How to change a pattern unlock from the phone settings without knowing the original
I have two unlock security options set up on my phone (HTC One). Firstly there is the facial recognition (which works well and lets me in) but on the occasions when it is too dark / doesn't recognise my face then it falls back to pattern unlock.

However, I have no idea what this pattern is as I set it up ages ago and the facial recognition works quite well so I've not had to use it.

I can get into the phone fine with face unlock, and can get to the security settings, but I can't change anything without first having to enter my unlock pattern.

If I can't reset this pattern that means I can't ever shave or change my haircut for fear of not being recognised by the phone!

Can I disable / reset the pattern security from within the phone? I have also got AirDroid set up on my laptop so that might open another route if I can't do anything from the phone itself.

How do I keep given apps always running? Looking for how to relaunch them periodically
Throughout the day, my phone's kernel kills my memory-resident apps at random, probably because the phone had run out of memory.  The apps are Backitude, Dropsync, Llama, MightyText, and Screebl.  (All five apps run as background services, yet my phone's kernel still kills them.)

The workaround I did is to have a Llama event that relaunches the other four apps every 3 hours.  The fourth app is tricky because Screebl doesn't turn on when launched.  So far so good. The problem is .. if the kernel kills Llama.

I'm looking for a timed launcher, I think.  It needs to launch Llama every 3 hours, so that llama can launch the other four apps, and this timed launcher, every 3 hours.  The set-up is sort of like those old Windows viruses that come in two executables; each exe makes sure the other is always running.  I cross my fingers the kernel doesn't kill them both.

I'm looking for suggestions.  How do I keep given apps always running?

P.S. Heh, I see that this is the opposite of this community wikied question.

I also have a Windows 7 laptop and it works there...

What Should I do?

found the solution!

First check if u have normal google adb drivers, if no then download them , put your device in usb debugging mode (this settings location depends upon your android OS version)

Go to Devices and printers in control panel -> go to properties of your device ( device should be connected) -> Change settings -> update driver -> Let me pick driver from my pc -> adb interface -> (it will give u list of adb drivers on ur machice) if you find any Samsung driver there click on it and click next or finish. Else choose google adb interface driver and finish.

Your device should be working properly with proper drivers installed :)

CM10.1, GS II, Mount command for encrypted sdcard0
Question: What is the syntax for the mount command within android to mount an encrypted file system?

Context:
I'm using CM10.1 (currently cm-10.1-20130604-NIGHTLY-I9100) on a Samsung Galaxy S2 (i9100) and have encrypted my internal sdcard.  On AndrOId 4.2 the internal sdcard (which is not a physical sdcard, rather a partition of the devices memory) is /storage/sdcard0, it has a link that points to /sdcard

After encrypting and rebooting the 3rd or 4th time sdcard0 doesn't mount.  Further reboots don't fix the problem.

/storage/sdcard1 (the physically removable sdcard) mounts fine.

When sdcard0 was mounted properly the output of the "mount" command included the following line which is now missing.

tmpfs on /storage/sdcard0 type tmpfs (rw,relatime,mode=050,gid=1028)

So,

What is the proper format of the mount command to remount this drive?

Any suggestions on how to fix or trouble shoot this problem?

Is it safe to keep Android charging through USB all day?
When I'm in front of the computer, I always keep my Android phone plugged into a USB cable so it's always at a 100% charge and I can type text messages from the convenience of my PC keyboard.

Still, I was wondering if charging a battery when it's already 100% charged hurts: Will it "wear out", ie. won't hold as long?

Generally speaking, is there a good article that explains how to charge and use the main types of batteries? For instance, I seem to remember that some batteries must never be left below 20% charge.

FWIW, I upgraded the original battery in my Samsung Galaxy Nexus to a slightly bigger Li-Ion 1900mAh.

Root Samsung Galaxy S2 with unconventional kernel version
My Galaxy S2 is running Android 4.1.2. I am following the howto here. I am trying to look for the corresponding CF-Root download, by looking in the xda-developers forum. The problem is that the kernel version of my device does not match the format given in the forum. Here are the details of my kernel:

```<code>Model Number     : GT-I9100
Baseband Version : I9100BULS1
Kernel-Version   : 3.0.31-889555 dpi@DELL228 #3 SMP PREEMPT Thu Jan 31 14:48:54 KST 2013

How to toggle hangouts

How can I troubleshoot MTP on my Galaxy Nexus
My Galaxy Nexus 4.2.2 won't show up as a MTP device anymore. It looks like the phone is the problem, I want to debug the problem from that end.

Like many before me, I tried everything, and then some :

Using Ubuntu 13.04 or Windows 7, on 3 computers

Cleaning the USB port on the phone

Using the original cables

Reboot with or without the cable, with or without the SIM card

Removing the battery all night (after shutting down the phone) to clear everything from memory

Uninstalling Google Play Music (I only use MTP to sync music)

I also have a second phone that shows up as a MTP device and syncs just fine. It is also a Galaxy Nexus running 4.2.2. Neither of them are rooted. So I think the phone must be the problem.

How can I troubleshoot or debug MTP problems on the phone ?

How can I view email in conversations view?
I am looking for a way to view my emails on Android in conversation style view, just like Gmail does. I've tried Aqua Mail, MailDroid, K-9 Mail and Kaiten Mail, but none seems to have a conversation view.

To be clear; I am not looking for a "Threaded view". A threaded view groups emails on the basis of subject, but does not include my own emails in that conversation. What I need is a way to view the emails as a conversation in which all emails, including my own, are listed.

Does anybody know how I would be able to view my emails on Android in conversation view?

May 2013 Gmail app update: "Reply as" multiple accounts gone? (Android 4.2.2)
I have two gmail accounts hooked up to my Samsung S4. When I go into the Gmail app and compose an email, I'm given the choice to send as any email address associated with either account. It used to be that I could reply to any email from any address as well.  So for example, if someone sends something to my work address I could reply to them from my personal address just by selecting the account from the pull down at the top.

Now it looks like I can only reply, reply all, or forward an email from any email address associated with that one account.  So I can only reply from my work addresses if the email was sent to a work address; I can only reply from my personal addresses if the original email was sent to one of my personal addresses.

This seems like a major loss of functionality!  Especially when Android will "share" from the last email account touched, it seems important to be able to quickly select which address to reply from / send from.

Can anyone explain this behavior?  Is this a problem for anyone else?  Is there a way around this?  Thanks!

Tablet not connected to N wifi
I have bought a cheap tablet, and it was not able to connect to my N-only wifi. When I set it to NG or G, it connected fine. So I took it back to the shop and had it replaced. The new one has the same problem. I have tried several channels and even disabled the encryption on the router, nothing helped.

The interesting part is, I asked my neighbour to change his network to N-only, and the tablet connected to that one.

Both of us have TP-Link routers, mine with DD-WRT, his with stock rom. 3 other android devices and a Win7 laptop connects to my N-only wifi without problems.

G is fine for browsing, but not enough for streaming.

Any suggestions?

Making Android phone locked using the SIM card password
When I press the power button. the Android phone will go into sleep mode.

When I press the power button again, the Android phone will wake up and ask me a password.

So, how do I make the Android phone ask me the password that belong to the SIM card instead of the phone itself?

What I mean is that the SIM card was locked with a password. The phone itself was not locked with any password (also not locked in pattern password). So, how do I make the Android phone prompt me the password of the SIM card every time when I wake it up regardless if I just power up the android phone or I just wake it up from a sleep?

Is there a countdown timer app that I can use with the hardware volume buttons?
I'm doing a kind of meditation that requires regularly setting a countdown timer for a few seconds, then when it stops and buzzes, starting it again. I've used a variety of apps for this, but with a touchscreen it's annoying to have to pay attention to where my finger is on the screen, just to hit the same button over and over.

It would be awesome if I could use the volume buttons on the side. I know some apps ("Stopwatch & Timer") that offer this in stopwatch mode, so it's totally doable, but I can't seem to find one that has this feature for timers. Anybody know one?

Can't boot phone or access recovery mode
I tried updating a custom ROM on my Samsung Galaxy S: Semaphore Version 9 (Android 4.2.2 Jelly Bean). The update was successful except that it produced an error after completion saying the process "android.process.acore" has stopped.

So I had to restore to the previous version through recovery mode. However after the the applications were calibrated and the phone was supposed to start, it did not! The boot animation kept on going. I tried restoring my phone to the back up that I had created when I was using ICS 4.0.4, but I realized that I had deleted the ZIP file of the ICS version.

Now when my phone powers on, it only displays the picture of the kernel version of the back up version of ICS.

I cannot access recovery mode. I tried to hard reset as well, as described in one of the links, but that didn't work either. However, The download mode works fine.

How do I keep my /system mounted as read+write all the time?
I'm running ChainFire3D and for some reason, the per-app setting doesn't seem to work at all. But when I set the default setting itself, it works.

After restart, /system was back to read only.

So yeah, how do I force it to always be moounted as read+write? This is on CyanogenMod 9, ICS 4.0.4.

But this is no-go. Nexus7 is displayed with conflict on the device manager. Automatic install won't install nothing. Drivers from asus website won't install (these are just ADB drivers). Basically no drivers I found over the internet won't install.

问:
LAN not working properly from one specific device
I have a Nexus S running cm10, which can connect without problems to the internal LAN. However my Nexus One running cm7, for reasons that are completely beyond me, fail to connect to it.

I'm totally clueless, I have no idea where I could investigate any more:

it is connected to the internet via Wifi, and access to the Internet works

access to the LAN, i.e. 192.168.1.0/24 addresses, doesn't

except that it correctly gets its IP address and routing informations via DHCP, just like the other device

Any idea?

They are all in the same net

192.168.1.152 cm7

192.168.1.156 cm10

192.168.1.169 osx

192.168.1.1 router

Investigating further I've noticed it fails to connect to my laptop (running OSX), but can successfully ping both the router (obviously) and the other android device.
(I'd stress that the other android device successfully connects to the laptop, instead)

logcat didn't provide any useful info:

ping returned "destination unreachable", and didn't log anything (even at Verbose level)

browser just returned a useless E/Tab     ( 8901): onReceivedError -6 http://192.168.1.169:8888/ The connection to the server was unsuccessful.

vlc remote reported that it found two computers I/*** bonjour ***( 8801): dbg: *** Added Computer [Palace of the Nine Moons] on 192.168.1.169
I/*** bonjour ***( 8801): dbg: *** Added Computer [Andalù IV] on 192.168.1.170
, but nothing else

Strangely, if I turn on the wifi on OSX, they detect it: they only have problems reaching the ethernet, for some reason that I still totally miss (yes, not even cm10 can't access it any more).

Disabling the firewall didn't work, but unless someone has a brilliant idea, I'd be inclined into thinking that is either OSX or the router that is going mad, rather than android.

I'll leave this open, though, since I really can't yet rule out android being crazy.

Strange Issue(Auto Touch) with Touch on HTC Desire X. Has anyone experienced this?
I have got a HTC Desire X about 3 months ago. I've quite enjoyed the features it comes with. For the past week or so, I have been facing with this strange issue. The touch screen acts as if it is being touched even when I am not touching the screen.

First, I couldn't understand what was happening as calls were getting disconnected or answered automatically. Then, I turned the Show visual Feedback for touches from the developer options in settings. I could now clearly see the screen is detecting a touch on its own.

I Factory resetted the device from the settings and from Bootloader as well. It works fine for a couple of days without any issues. But, the issue comes back.

Please help me with this issues.

Thanks in advance.

TLDR: Touchscreen touches automatically. Factory reset resolves the issue, but only for some time(2 days at max, an hour at min).

Battery percentage going down while charging!
(device: Samsung Galaxy S 3)

I've just witnessed something rather strange: while tethering to my laptop, with the phone being plugged in a power source (the charger I got with the device) - the battery percentage started going down.

Now, I'm in an area where the signal is pretty bad, and my phone is constantly switching between 3G and some H+ network. It's normal for the battery life to suck.

However, isn't the phone supposed to power itself directly from the charger?

I thought that the charger was both powering the phone and recharging the battery.

Now it seems that the battery is powering the phone - while the charger is only recharging the battery (and failing).

Is this correct?

Even more importantly: will this hurt my battery?

And another question: could I simply take my battery out and keep the phone alive only on the charger (e.g. this is possible with a laptop)?

The odyssey for CM10, all i get is a bootloop. How can i solve this?
I'm here to discuss about the unlocking of my new LG Optimus L5. I'll start saying that it come oot with Android 4.1.2 and the LG mod v20b.
I wanted to delete all the LG stuffs that slow the phone so i decided to root+unlock bootloader+install CWR+flash CM10 and Gapps.

I started following this page and tried all the root methods; only the one using a modified kdz worked.

After that i tried to unlock the bootloader, succeeding only after a day of tries. The problem was the Superuser app (it won't allow the ADB shell to edit the bootloader information even if it was allowed. I don't know why), so i installed superSU and all went right.

After that i installed ROMmanager, which allowed me to flash the CWR, but i was able to enter it only if the USB cable was disconnected (again i don't know why).

Inside the CWR i wiped bot caches, i did factory reset and flashed CM10+ Gapps; unfortunately i installed the wrong Gapps, denying me the Camera app, and few more little bugs...
So i decided to flash the righ one (gapps-jb-20121011-signed), but after that, all google services was crashing, so i decide to factory reset all and reinstalla CM+Gapps (the righ one this time)

The fate decided to curse me, sending the phone in bootloop after the flashing.
Hopeless, i tryed to flash again the modded firmware with the kdz flasher to retore the phone at the first passage, but it remained in bootloop (this time with the LG logo, not with the Cyanogen one).

I'm now trying to restore the original kdz (the v20d not modded) hoping for some miracle.

Someone have a hint to help me? The only thing i know now is that i can put the phone in download/emergency mode or remain in bootloop.
As far as i know the only way to enter the recovery is from SU binaryes in this f***ing phone, so no key combination to enter in it at startup.

How can I enlarge the fonts on Wikipedia in Chrome?
On most web sites, when I look at them with Chrome on my phone (a Nexus 4 running stock Android 4.2.2), I can adjust the font size by double-tapping a column of text to make it widen to fill the screen.  However, this doesn't work on Wikipedia.org; I don't know why -- the text is quite small.

I've already got the browser set up to display (very) large fonts: I'd gone to "settings", "Accessibility", and have cranked the "Text scaling" slider over to 155%, which is ginormous.  (There's also a check in the box that says "Force Enable Zoom", which I don't recall setting; I guess that's the default).

Anyway: this feature works fine on most sites, just not Wikipedia (and perhaps a few others).  Any advice for making Wikipedia readable?


问:
"fastboot -l devices" returns nothing
I'm a newbie trying to learn about what alternative firmware I could use to upgrade my Nexus Galaxy from Android 4.2.1.

After connecting the phone to my Windows PC with a USB cable, I followed this video on YouTube to start the Nexus in Fastboot mode, clicked on the right button to proceed, and once Android was up and running, ran this from Windows...

[c:\Android-adb]fastboot.exe -l devices

... which returns nothing.

Any idea why, and what to do?

FWIW, the phone is also running an ADB server since it's used by the MyPhoneExplorer application to sync Outlook with Android.

Thank you.

Edit:

The computer already had the Samsung driver since I'm using MPE to sync Outlook with the Android phone.

Next, on a new computer, downloaded and installed Galaxy Nexus Toolkit 11.1.0, and rebooted as prompted by Windows7. With phone plugged in, Windows7 detected the phone allright.

Rebooted, left in Fastboot mode: fastboot-toolkit.exe says nothing, and Windows7 complains with "Device driver software was not successfully installed".

Couldn't uninstall GNToolkit, as it's not listed in Programs. Downloaded and unzipped Android SDK in c:\Android-adb\, edited PATH, rebooted, and with phone still plugged in and waiting in Fastboot mode, ran "fastboot.exe -l devices": Still nothing.

Edit:

On new computer, downloaded and installed Galaxy Nexus Toolkit 11.1.0, rebooted as prompted by Windows7

Without rebooting, plugged phone: Windows7 complained with "Device driver software was not successfully installed". Followed this howto to manually update driver.

Rebooted with phone still plugged: Phone detected OK.

Rebooted phone in Fastboot mode, and rebooted Windows7: "Device driver software was not successfully installed" followed by "Google Galaxy Nexus BootLoader Interface: Failed".

Device Manager shows faulty "Android Device > Google Galaxy Nexus BootLoader Interface", but telling Windows to look for driver in C:\GoogleNexusToolkit ends with "The best driver software for your device is already installed."

What could be the problem?

Thank  you.

问:
Why the battery drain while plugged in doing nothing? (omap2_mcspi)
I usually leave my phone plugged in to the wall charger at night.  This morning, to my surprise, the battery was not charged.  According to the System Panel app, System Processes were taking almost 10% of CPU during the entire night.  The biggest consumer was omap2_mcspi, taking nearly 15 minutes of CPU time, followed by khelper and cpcap_irq/0 both taking around 5 1/2 minutes, then ueventd and used at around 3 1/2 minutes, followed by battd at 3 minutes and vold at 2 1/2 minutes.

It seems pretty ridiculous to me that my battery would be running down while on the charger with the screen off and nothing (that should be) running.

Other than system processes, the only other thing taking any appreciable amount (around 1 minute) of CPU was "usb" which shows up outside of system processes.  My best guess is maybe the USB plug had some kind of issue, but I don't see any evidence of this (battery status updates don't show any apparent unplugging).

Using Bluetooth headset for voice calling on Nexus 4 Stock
I know that people over the net have reported that they were able to place a voice call using one of their Bluetooth headsets.

I have a Sony Ericcsson HBH-DS970 headset which pairs with my Nexus nicely and I am able to use it for audio with no issues, but while placing a call I have no option to use the headset instead of the default mic and earpiece of the phone.

Am I missing some of the settings that make this option is available for me?

The Bluetooth setting says that the headset is connected as "phone audio" as well as for "media audio".

I guess "phone audio" means voice calling through this headset (which isn't working for me) and media audio is the music audio (mp3 players and normal android sounds) that's working fine for me.

Then why am I seeing no option for placing voice call through the headset?

Android phone dialer home location
I remember from my HTC HD2 running Cyanogenmod 10.1 a "home location" indicator. It shows the area name of the caller's landline if somebody is calling. The default phone dialer app on my Newman N2 phone running Android 4.1.1 displays a home location in Chinese, instead of my native language (which is Dutch). My settings and stuff are Dutch (so is the rest of the dialer).

The setting can be enabled/disabled here:
Settings -> Call Settings -> "Display Home Location".
(I think it's not available on every Android ROM)

I want that home location indicator to be Dutch. I tried to decompile /system/app/Phone.apk, TelephonyProvider.apk and NetworkLocation.apk, so I could change the Chinese language to Dutch. Then I searched through all of the xml files, but with no result finding the Chinese letters.

To decompile the apks, I used the following tutorial:

Minimum lcd brightness on android 4.2.1
I'm looking for a way to reduce the real brightness (the backlight) of my lcd. I'm using android 4.2.1 on a Star b94m/b943.

I search for apps, and i found RootDim, which can decrease the light below the minimum 30/255 (default by android).
I found another great app, Velis Auto Brightness, which allows to control the brightness in function of the light sensor. It can't go below the 30/255.
So i thought if there were a method to reduce the default android brightness i could use Velis Auto Brightness (so auto brightness) AND use lower than 30/255 levels.

Google Music won't cache my songs?
I haven't updated my Google Music in ages (I still had the blue interface) but when I updated it to the latest version, I had to clear my song cache because some of my music weren't playing correctly. This time around, it seems to stream the music all the time. I only have internet when I'm around wifi and I rely heavily on its caching so I can listen while on the road or offline. I didn't even have to specifically mark my songs as "Offline" on the older version I had, they just get stored as soon as I finished streaming them once.

So, what gives? Also, I assumed that they simply changed the behavior so that I am required to tick on the "keep offline" option this time around but I can't even find that option anywhere. Is this issue happening to other Google Music users?

I bought my HTC One V exactly one year ago, at first everything went really smoothly and it worked like a charm.

It didn't take long before the phone crashed from an unexpected error. The phone spent most of the time in my pocket then, I would notice it because it vibrates then or the next time there would be that error-sign in the upper left corner.

I started living with the fact it sometimes shut itself down, but now the messaging app is beginning to lag:

How can I know that my Galaxy's camera and microphone is not being accessed without my knowledge?
A few months back I installed a few apps straight from the internet. One was an ability to run Ruby scripts on my phone, the other was Grooveshark. Both times, an Jellybean 4.2 flagged up a warning saying these programs have the potential to access my camera and microphone, but I ignored them.

Now I'm getting a bit paranoid. With the macbok pro, when the camera is accessed, a little green LED lights up. It's 'hard-wired', as even security programs (for when your macbook's stolen) can't take a photo without the LED lighting up. Luckily, the LED is brighter than your average laptop-theif, and it only lights up for a second, so no problem there.

But with an android you literally have no clue. I tested out the security program Cerberus, and it took videos of audio samples using my Galaxy without the phone giving a hint what was happening.

I've deleted Grooveshark (it's an abysmal app anyway), but I'm still worried about some other program from months ago recording me.

OS Update moved external_sd to extsdcard; Apps previously on SD card are now missing/uninstalled.
I just upgraded my Galaxy Note (1st gen) from ICS 4.0.x to JS 4.1.2. I'm using the Samsung ROM supplied by my carrier (with all the bloat in it).
After the upgrade, I noticed many of my apps were missing (the ones installed on the SD card), as well as my photos/videos and personal files (previously stored in sdcard/external_sd/DCIM/...).

So I checked various parameters, and using a file explorer, I found out that all the sdcard/ contents moved to storage/sdcard0, and the sdcard/external_sd moved to storage/extSdCard.

WonderMedia 8650 ICS 4.0.3 - what is "3g_server"
I'm trying to understand how a WM-8650 based Android tablet running ICS 4.0.3 manages its 3G connection using a USB modem.

I've used OpenWRT-based linux routers in the past, and these use usb_modeswitch to kick the modem out of "CD" mode into "modem" mode, and then pppd starts up and uses chat to set up the connection, though I've never quite got to the bottom of how the USB hotplug system kicks things off when the dongle is first plugged in.

With Android I can see similar things happening - usb_modeswitch kicks the dongle into the right mode, and a renamed pppd (called ppp3g) sets of the point-to-point protocol.  However, this is all done under the control of a process called "3g_server" which I've been unable to find any information on.

I'm trying to debug a problem where a dropped connection fails to come back up very quickly, so I'd like to understand how 3g_server works and what options I have for tuning that behaviour.  A configuration document would be handy, source code would be better.

问:
Standalone program for managing encrypted partitions? Or, How can I manage encrypted partitions in recovery mode?
Android uses dm-crypt for providing disk-encryption as stated in the implementation notes. Those notes also state (emphasis mine):

While the actual encryption work is a standard linux kernel feature,
  enabling it on an Android device proved somewhat tricky. The Android
  system tries to avoid incorporating GPL components, so using the
  cryptsetup command or libdevmapper were not available options. So
  making the appropriate ioctl(2) calls into the kernel was the best
  choice. The Android volume daemon (vold) already did this to support
  moving apps to the SD card, so I chose to leverage that work for whole
  disk encryption. The actual encryption used for the filesystem for
  first release is 128 AES with CBC and ESSIV:SHA256. The master key is
  encrypted with 128 bit AES via calls to the openssl library.

Once it was decided to put the smarts in vold, it became obvious that
  invoking the encryption features would be done like invoking other
  vold commands, by adding a new module to vold (called cryptfs) and
  teaching it various commands. The commands are checkpw, restart,
  enablecrypto, changepw and cryptocomplete. They will be described in
  more detail below.

So Android does not an existing tool due to licensing issues... As a user in recovery mode, I do not have vold running and would like to have a minimum program that can:

Create a new encrypted partition.

Unlock existing encrypted partitions.

(optional) View information about the encrypted partition.

Does such a program exist? Ideally it can also run in a non-Android environment, but at the moment it is important to create an encrypted partition in recovery mode.

The subject OS is Android 4.2.2 with CWM 6.0.3.2 as recovery image.

Add calendar event via freeform text w/documented, unambiguous syntax?
Is there any way (probably thirdparty app, assuming it's not some secret hidden option in CM10.1) to add calendar events on a Galaxy S3 running 4.2/CM10.1[RC5 at this moment] with a syntax like:

```<code>on Monday [or "next Wednesday" or "July 7"]
at 3pm
call 3055551212,99988877#
re call with somebody important
for 30m
notify 10m,14h
</code>```

via some method that's actually

documented somewhere,

has deterministic & unambiguous syntax, and

Allows you to set the 'location' field of the calendar event to a clickable phone number that includes comma (pause), additional digits, and trailing '#'?

Over the years, and with various ROMs I've installed, I've seen "quick input" methods like this seemingly come and go at random, with basically undocumented syntax and unreliable handling of "clickable phone number as location that includes pause & extension#".

I know that someone, somewhere, SOMEHOW, has to have actually gotten this right... but who? (Or, where's the option, what's it called, and where is it documented)?


问:
Can I browse a locally hosted web site from a USB connected device?
I am attempting to remote debug a locally hosted web application on Nexus 7 and 10 tablets running Android 4.2.2, that are connected to a development machine via USB. My goal is to browse to the equivalent of 127.0.0.1:xxxx on the tethered PC (so from the tablet I would expect to browse via the host PC's IP address 192.168.1.100:xxxx).

I do realize this can be accomplished utilizing Wi-Fi, but unfortunately the tablets are not connected to the same network as my development PC and can not be. Bluetooth is also out as my dev machine does not have Bluetooth.

It seems like utilizing reverse tethering would allow me to browse to the host machine. The reverse tethering solutions I've tried to utilize have focused on simply using the PC as a pass through to the internet. In any event I have not been able to successfully setup reverse tethering much less browse to the web application hosted on the connected development machine.

Using a USB reverse tether solution is it possible to browse a locally hosted web application? Is there an alternative to reverse tethering that will provide the same capability? Can I browse a locally hosted web site from an Android device connected via USB?

Note 10.1 stuck in restart loop
I bought the Note 10.1 two months ago. But now my Note is stuck in a restarting loop for a second time. First, it happened last month. I already got that fixed by the service center. I asked the service center man whether I can fixed it by myself or not. He told me that you couldn't. Now, my Note 10.1 is constantly restarting again. I don't know what exactly the root cause of this issue is. I remembered that last activity was I only registered new account for Line and ChatOn app. The problem condition is when entering the boot screen, the note 10.1 just restarts again. So it never reaches the home screen. Any body know what is the root cause for this? How can I fix it by myself?</p>

Strange PDF scanned character rendering in Android
I am using Android 4.0 (ICS) on a Samsung Nexus S 4G.  I have a PDF of a scanned book (text/graphics).  The PDF displays fine on a PC.  On the Android device, every single "d" and "o" character has the white space in the center (i.e. the "hole") filled in completely with black.  I've tried a half dozen different viewers and they all display it the same way.  I've tried re-rendering/printing the PDF on the computer before putting it on the mobile device, and still no luck.

I'm guessing it has to do with some Android system level driver that is shared between all the viewers I download.  Any ideas how to fix this?


问:
Snapshots suffer from Short Term Memory Loss?
I have seen that despite repeatedly saving to snapshot, periodically (once in about 3 attempts to launch from snapshot) I get the error:

emulator: ERROR: Unable to load VM from snapshot. The snapshot was saved for a
  different hardware configuration

This forces me to go the old way (boot and wait 150-200 seconds) again try saving to snapshot and then launch. This phenomenon has been happening for quite some time now.

That said, I have settled for a system configuration (after all the only change in configuration from the default is that in the preferred setting all IMEs are disabled). That is it. No system apps installed like Google Play, etc. No system apps removed either. I have not changed the system/hardware configurations for the last one week.

I later came to know a command whereby the emulator can load from snapshot so that on closing it, the SDK doesn't save it to snapshot. Just run

```<code>emulator -no-snapshot-save -avd Andreud
</code>```

in the terminal. I was relieved since

It will be good to not save to snapshot and save processing time, when you know you aren't making any more system/hardware configuration changes.
I suspected that there were some unknown aberrations in saving to snapshots sometimes and is what resulted in the error, so avoid it rather than cure it.

Yesterday I discovered that the problem persisted! It persists to this day! What amazes me is that when I no longer write to the snapshot image, it still forgets the configurations stored in the snapshot so soon! I even tried to do it after freeing up RAM space by running solely the emulator and none else!

Any help to rectify this is welcome.

P.S.: I have given -no-boot-anim option to the emulator command as well. So if not loading from snapshot, at least the boot happens in less time.


问:
Would any of the advanced Linux/UNIX filesystems be viable on Android?
I know ext4 is already used as an internal filesystem but I wondered if there would be anything gained by using something like btrfs or ZFS? I know they are meant for more server-oriented situations but I'm just curious if there are any features that might help on a flash memory based smartphone.</p>


问:
Is there any way to root JB without losing all data and settings?
Is there any technique to root Jelly Bean (perhaps temporarily) without losing all data and settings?
The phone is Nexus S i9020 with Android 4.1.2.

The phone has a bad case of the "Lag" problem - AndroBench reports:
Random rd 4.4 MB/s  (1127 IOPS)

Random wr 0.18 MB/s 49.86 IOPS.

I have found "LagFix" as a possible solution but it requires root.

I have no other reason for root, and would be happy to have a "temporary" root that would let me run LagFix to solve that problem, and then be back to unrooted after restarting.

I checked the suggested answer (This question already has an answer here:) If I root my Android phone, will I lose all of my data?, but it is from 2010 and recommends a tool (Unrevoked) that only supports specific phones (not including the Nexus S).

I saw a different approach here but it appears to be for Gingerbread 2.3.3 and prior. I'm running JB 4.1.2.

So I'm still looking for a way to root JB without losing data.
