[Q] LG MyTouch Q CM9 freezing problems

First of all, thanks to chui101 and all the other people here who put in the effort to get CyanogenMod to run on this phone. However, I'm having a bit of a problem with my phone slowing down severely and becoming unresponsive, usually at the lock screen. The specific issue is that the lock screen will be on screen, but not respond to button presses, or respond very slowly, and then it will do the "old CRT television turning off" effect much much slower than it's supposed to (think close to a minute), go blank for a while, the lock screen comes back up, another very slow screen turn off effect, and the whole process keeps repeating until I get tired of it and pull the battery to reboot the phone. This issue happens to me with both the 2012-11-21 and 2012-11-25 nightlies. To me, the behavior sort of seems like an out of memory issue, maybe some program is leaking memory or something.
Things that cause the freezing issue:
Power button presses too close together
2 cases of a call coming in while the phone is locked and playing music in Apollo
Things I've tried thus far:
Switch launcher from Trebuchet to NovaLauncher
Set Background Process Limit from "Standard Limit" to "At most 3 processes"
Set "Force GPU rendering"
Remove SD card
Out of those, pulling the SD card is the only one that seemed to help. The SD card I had installed was a 16GB SanDisk Class 2 card with ~3.7 GB of music along with less than 10MB of small text files, ring tones in .wav format, pictures, etc.
I put the 2GB card that originally came in the phone back in, this card currently has nothing but the text files and ringtones and a few pictures.
Is anyone else getting hit with this problem? What can I do to help? I don't know much about android ROM development, but I can handle collecting a LogCat from a case where the problem I'm describing is happening and know a reasonable amount about general Linux stuff, just not Android internals.
Thanks!

I used to own an LG Mytouch Q, the only reason I'm even remotely interested in this thread.
However, you should definitely post in that specific thread, as it's basically the only group of Mytouch owners and they should give you lots more help

I would, but I just joined here so I can't post in the dev forums. I'm hoping someone there will see this post.

Update
With the smaller SD card without all the music files installed, I'm getting less of the freezing problem, although I am not certain whether this is due to the music files not being there, or me not using the phone to play music. I guess the next part of this experiment is to go back to the card with the music files on it but not play any of them. I did grab a LogCat from one of the cases where the phone is 'freezing' and see a bunch of "Application Not Responding" messages, and the CPU usage stats that follow these messages indicate that most of the CPU time is being used by 'iowait,' for instance "100% TOTAL: 0.3% user + 6.9% kernel + 92% iowait". I've read some threads relating to other phones indicating that this could be some process poking around somewhere in storage. I'm thinking that running top from adb shell next time the phone ends up in this state might give some clue as to what's eating the CPU.
Also, I've hit the issue with email message bodies showing up blank that others on this phone, and on CM9 on the non-keyboard LG Mytouch (E739) have experienced.

Hope I'm not spamming with yet another status update, but I tried disabling live wallpapers (going instead to no wallpaper/black screen) last night, and I haven't had any of the freezing problems today. I'll try adding the music files back and see if the problems return then.
* Update 11/29/2012
I put the 16GB card with ~4GB of music back in the phone, used it all day at work for listening to music/checking email/some web browsing without any crashes. (Still with live wallpaper disabled) So, I'm starting to think live wallpapers are causing my problem.

[Q] Media service drains battery after restart

Stock, Non-Rooted, Verizon Galaxy S3 4.1.2
I535VRBMF1
I've been experiencing the media scanner battery drain issue now for months and I can't figure out how to solve this issue. I've tried the following:
+ Factory Reset
+ Removed SD Card, removed all files, formatted and copied all files back
+ Delete cache for many apps including podcasts
+ Removed SD Card and reboot - Media Scanner still runs!
This problem typically runs after reboot and continues to run, with the phone running hot for about an hour. I typically lose about 20% of battery power doing this. It's inconsistent. Sometimes the scanner crops up and refuses to stop at all. During this time, the phone has a wakelock and becomes warm to the touch, draining battery at a rapid rate.

This is not the verizon forum.
However if it is still running after removed SD card, the problem is probably on your internal memory (/sdcard) It may be worth backing up your data and factory reset (wiping internal SD).
Someone said its to do with thumbnails so try and clear these first just incase that helps.
please use the /!\ button to report your post to be moved to the correct forum.

I suggest you root your device and download 'Rescan Media Root' from google play.
That fixed my problem.
I also heard adding '.nomedia' file in all your folders that does not have media files will prevent scanning those file.

One of the first things I did was do a factory reset but the problem remained. I'll move on to deleting the thumbnails and see if that helps.

Mediaserver killing my battery?

Did a search for Mediaserver in this sub forum, and didn't find anything.
Is anyone else having an issue? I'm down to 15% battery after 6.5 hours, which is weird, considering i only use the phone for maybe an hour total here and there.

Try wiping the data for it and rebooting.

No problems here.
Although I hear the Samsung S4 (and perhaps other phones) suffer from this process using a lot of processing power.
I hear it's due to duplicate music (media?) files or some funky named music files.
Other causes have been due to these apps and maybe others: Asphalt 8 / Yahoo Weather app
Try restarting into safe mode to see if it helps. Hold down the power off option (the menu you get holding down the physical power button).

Mediaserver will show up for two reasons:
1. You're listening to music or audio
2. You have a corrupt file on your phone and it gets stuck.
Your's is probably number 2. Unfortunately, the only thing you can do is find the file. It doesn't even have to be an audio file. Easiest way is to back the storage up to a computer, delete everything on the phone..verify the issue goes away and then, if so, slowly put stuff back on until you can find the offending file.
This is true of all Android phones. Happens sometimes.

That's the thing I didn't put ANY files on the phone. Everything was re-downloaded from GP. I didn't move any backups over at all either, no pictures, music, anything...
It seemed to have stopped once I force closed GP Music.

Testing Nexus 5 memory?

Is there a tool or way to test the Nexus 5 sdcard memory?
For the last six months I've had problems with my rooted Nexus 5 (stock kitkat) suddenly running very slow. After a lot of time trying to figure out why, I determined the following.
1. Slowdown happens when an app is writing something to the sdcard.
2. Is not a particular app. Can be any app.
3. When it happens all 4 CPU cores are running close to full blast.
4. Battery usage shows "android os" is 50% of the usage.
5. Task killers do not solve the problem.
6. Reboot restores things to normal for a while.
So I now wonder if there's something wrong with the built in memory but don't know how to test it.
Is there a way to test the Nexus 5 message? It is very frustrating to talk 2-3 pictures and then have the 4th one make everything grind to a stop. Right now, typing this is a pain because every letter takes its time to appear. I know rebooting will solve it but I should not have to.

sounds like you get a process(es) that get "stuck". also, when this happens, have you ever checked if your google stuff is syncing or " stuck"? sometimes badly written apps can cause this to happen as well.

I think you are right but I don't know how to find the faulty process. I "think" I first noticed it after the google camera update, but I used settings /apps/ to uninstall the camera update without improvement. I think camera showed the problem because it has to save the image to memory sdcard.
I don't sync and have sync turned off everywhere and on all apps. Sometimes Google play shows up as the prominent battery user even though I don't have it update apps automatically. But it is primarily android os that is the bad guy.

One of the things I had tried when the problem first started was to restore an earlier nandroid backup, but the problem continued, so I restored the most recent nandroid I had done before the earlier restore.

Recent screenshot.
I was on the browser and Tapatalk for a while. But not on play store.
Not frozen now when taking this screenshot.

You need to get gsam, or BBS or wakelock detector and see what one of those says. The stock battery screen is pretty much useless to find a battery problem.
But I'm guessing all your issues are tired to one bad app as said above.
Get a battery app I suggested, run a full charge down with it running.... And comb thru all of it and see if anything pops out.

I already did that. I have gsam and wakelock detector installed but my knowledge of Android is very limited and they have not helped me so far except to confirm I have a problem. I wonder if there is a way to see the dates I installed various apps. That way I could uninstall in the order they were installed.

Here are various screenshots. The list of active processes goes down several pages.

My guess... It's an app that hadn't been updated since kit kat has been out, and it's spamming location services.
Just a guess.
Check in gsam for times waking device, held awake time and kernel wakelock. (You need gsam root companion from play store installed as well.). These are all found in gsam app screen by clicking the drop down at the top. See if anything looks bad on any of those.

Oh, and obviously, whatever tick tick is, is killing your battery. If it accesses location.... that's my bet for the culprit.

Thank you all for the advice. Obviously I've tried various things. TickTick is a todo list app. Quite nice actually. Anyway I had suspected it might be a problem and have uninstalled it (several times) with no improvement.
Finally, I seem to be making some headway. Don't know which of these two did it (if the improvement lasts.....).
1. There were 3-4 apps I had avoided updating because I didn't like the updated versions (maps, Hangouts which I don't use, Firefox, etc). So I now gave up and clicked on "update all".
2. I disabled the module gravitybox and rebooted.
So far things have returned to normal. My CPU cores are back to low levels.
I'm keeping my fingers crossed. If things continue well after a while I will reactivate gravitybox. I'm holding my breath!

After a full 15 minutes of normal behavior (unbelievable!), I took my courage in hand, reactivated gravitybox. Used my usual apps without the previous freezing recurring (so far). If this continues - and it seems to - it might suggest you don't update GAPPS (I think it was Hangouts) only at your peril.
Such a difference having an uncrippled phone!

After a while the slowdowns returned. Any suggestions?

Question S21+ snapdragon issue

Hey
I am have problem with my s21+ g996u1..after frimware update i noticed that there is some app that trying to open randomly in background but then it close immediately..that happens every few minutes
There is a way to downgrade frimware?
There is a way to Recognize that app that trying
To open randomly and close?
Please helps

You can't degrade easily if at all from the factory installed version. Android 11 is a nightmare.
Start like this...
Clear system cache.
Fixed?
Try in safe mode, if this resolves it, it's likely a 3rd party app you loaded.
If it still is doing it in safe mode, it's a factory loaded or system app.
Go to Device Care>Memory, clear the apps.
Back out of it then open it again.
Expand the list and see if you can spot the app doing it as it loads. Disable that suspect app(s) to confirm if it's the culprit. A package disabler app is very nice to have when doing this.
With some persistence you will find it.
~or~
The easy way...
Go to a Samsung Experience center at Best Buy and have a Samsung tech run a diagnostic on it.
They can likely spot it.

On Battery and device care, click on bar graph in top.
Check the app issue, maybe will show your bad app.

Maybe but many apks are lumped together in Android Services. It's likely one of them or a Google app.
Problem apps don't always show under their name... that happens sometimes with the Google system apps.

Same here, S21+. After August update I've had the same issue as you, plus youtube fullscreen exiting every ~5 mins, Google Maps minimizing to window every ~5 mins, massive (2s+) freezes in games. None of this existed prior to this update. Someone messed up big time.
I installed the October update yesterday - to no avail, the issue persists.

If you mean power saving, then no, that's not the case. System cache clear didn't help either but I've just cleared the phone (factory reset), restored data with Smart Switch and looks like this helped. Gonna test it a bit more to confirm the solution.

Good. I avoid doing all firmware updates if my OS is running fast, stable and fulfilling its mission. Security is not an issue as best I can tell unless you do something stupid*.
Updates can do a lot of damage... if you like your OS, let it be.
*always backup critical data redundantly to at least 2 hhds that are physically and electronically isolated from each other and the PC.
You can use a OTG flashstick for quick "dirty" backups, but have the bulk of the backup on data hdds.
I use my SD card as a data drive on my N10+'s, then backup that card. That's why I demand a SD card slot; dual drive setups are the only way to go. The OS, apps, and the temporary download folder are the only things on the internal memory.
In crashes the data drive is usually spared. I can do a full manual restore from that data drive minus a few lost settings.

On my S21 Ultra (SM-G998B/DS) I have the same issue with "background activity" creating screen hick/refresh and switch from landscape full screen video to portrait mode.
Started after November security FW update end October.
Checked all possible settings and removing all 3rd party apps, hick-ups do persist...
'Glad' to read about this issue/bug here too, as I started to doubt myself...
