[Q] Sluggishness building over time ?

Hey guys,
I have my Nexus S (9023 variant) for some good 4 months now and I'm still quite happy with it!
Running unrooted stock 2.3.4 version.
However, I seem to feel like the phone is getting a bit jerkier / sluggish than it used to be before. I've noticed an increase in battery consumption of the Android OS process (not the system one) as opposed to before (like in a 100%-0% charge, it used to be 1-2 minutes, now it can go up to 10 mins time usage).. Sometimes going from one app to the other seems to have a noticeable lag. Sometimes the Google Music player is just slow to start playing... sometimes even the swiping of the home screens dies.
Also I used to have 2 days battery life and now some 1.5 days (which forces me to charge every night).
I would suspect than an increase on the Androis OS process would mean an increase in internal task switching.
How can one alleviate the problem ? Is there a way to sort of "cleanup" the system ? Does it degrade over time needing a factory reset or something ? I have some applications installed (some of them I hardly use though) but I suspect that even though those optimizations have their notifications disabled, they can be reacting to some kind of low-level OS events..
Anyway thanks for any thoughts guys!

What ROM are you running? And I would suspect that apps are the main problem if it persists after a reboot.

Stock 2.3.4, unrooted
Guess it's on to uninstall some apps then

Factory reset would solve all your problems I assume. Pity you are not rooted so you can back up your ROM.

I'm actually thinking of rooting soon, because I made some video recordings in a concert and they were plain horrible (distorted). So I might try to install a kernel with voodoo.
I guess I can always manually backup for once...
I have the google services backup activated... doesn't it mean that I can restore all my apps after a factory reset ?

You can use that to clean up your caches. I suspect a lot of programs installed or one or a few that are pulling your performance down. You could go about this in a few different ways. One is to uninstall everything you've downloaded from the market. That should give you a boost. Or you can start uninstalling programs one at a time until you see your performance increase then that's your culprit. Another idea is to delete all your SMS, MMS, and voicemail. I've seen people with hundreds of texts that after deleting them, notice an improvement.

A cache and dalvic cache wipe would help speed things up. Hopefully that market app above can do both. Normally done through a custom recovery.

Nice ideas guys!!
Think I will try to install titanium backup and backup my apps. And since I'm on it, I will also root my phone and install the net archy kernel cause the last time I took my phone to a concert I ended up with 1 hour of unusable footage due to sound issues.

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?

mm-qcamera-daemon on 4.4.4

I had this on 4.4.2 but 4.4.3 fixed it. I'm on 4.4.4 now and have been since it came out, but all of a sudden last week, mm-qcamera-daemon came back and I'm not alone.
With L just around the corner, I doubt there will be any fix for this from Google, so what's the best way of finding out which app is keeping this service alive?
P.S. I have neither Skype, Instagram, nor Snapchat installed - and never have done - so it's not them.

Did you have a camera app running in the background? ie. minimized it without swiping it away.

Nah, nothing like that. I'll even get it when I boot my phone, open no apps at all, and charge to 100% before unplugging from the charger - this action seems to be the cause of the daemon, like some of the other users on that issue report are saying. Never mind, I guess I'll just wait it out until L.

I have never had this problem on my nexus 5 until today (I bought the Nexus 5 on day one)!
This process is draining all my battery!!
The only app I installed in the past week is "Google Opinion Rewards" which was installed 6 hours ago.
Please help if you find a solution
UPDATE 1: I just noticed, via CPU-Z, that all 4 cores are continuously active at high frequency and the phone is overheating
UPDATE 2: Problem is still there even after removing "Google Opinion Rewards"

Just reflash the stock firmware and see if it continues.
Best thing to do with any issue that a solution can't be found for easily. ?

the camera daemon is supposed to appear. its not supposed to stay around, draining battery. especially at 100%, you will see it, as the phone uses it a little bit, and you havent used the phone at all. it will show up. the question is, if you dont use the camera at all, and it appears in your battery stats, after a full cycle of use, how much battery does it take? chances are that by the end of your battery cycle, it wont even be in your battery stats.

I actually fixed it now by flashing the system image and restoring all my apps via Titanium Backup, but I swear I'd never even open Camera for it to occur, and I don't have any third party camera apps. It would constantly be active without opening any camera apps at all.
edit- also Google have restated that they're looking into this bug and have marked it urgent, so anyone else getting it - don't panic too much, it's most likely not a problem you've caused.

I suspect the Hangouts/Hangouts dialer. I updated the app few days ago (no other installs), today was the first time that I got this issue (got my Nexus in February). Also first time since updating I used the camera, followed by battery drain/ daemon/ "failed to connect camera" etc.

I think its because of android wear
With android wear u can access the camera, hence u will be seeing the camera drain for sure. i unpaired my watch for few days and i didnt have this problem till now

I had this problema today morning, my android version is 4.4.4, In my case I used yesterday the camera to attach a photo inside the facebook messenger, maybe this buggy app make this mess in my case.
I reboot and waiting for the results

Same here
Everything was ok from 4.4.2 till 4.4.4. But suddenly week ago discovered mm-qcamera-daemon issue, tried many things without success. I am using phone in safe mode (facepalm).
Waiting official Android L or fix from google.

I got the same issue now!
Started today, what the hell?

Some apps will keep the camera wakelocks going. Freeze anything that can possibly use the camera and see what happens.
Or just clean flash stock, and see if its OK. If so... Install a handful of apps per day.... Then if it goes nuts you know it's an app you've just installed.

https://code.google.com/p/android/issues/detail?id=70755#c171

I think i had this fixed. Ihave a rooted nexus 5 stock rom. Installed greenify, pirchased the donate version and had the camera app greenified. No more mm-qcamera-daemon showing up on my battery stats. No more "cannot connect to camera" issues. (So far it's been 2days without it.

camera block app
i see this issue occurs when i use skype or any camera related app in my grand 2 4.4.2 / only way i keep the issue at bay is use camera block app.. which i keep it turned on when i am not really using the camera.
this seem to keep this daemon under control and not drain my battery .

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.

Sounds like power management is active.
Disable it...

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...

Question Unknown hidden system app after OS 13.1 Update //added major battery drain since apps now won't stay closed after forced close.

Hello there. I think my phone's been compromised. It's been acting up since my last OS update. I have a OnePlus 9 LE2115, currently running oxygen os 13.1.
I was searching through apps because something's draining my battery and i noticed that all of my apps are always running even tho I've turned them all off manually and turned off background data usages. I can't force stop on about 60 percent of my apps anymore.
Upon further inspection, i found a few system apps I've never seen before and cannot find any info on when googling.
App #1- Metis ( i cannot find any info on this at all or delete this app but i have disabled it but i don't think that did anything) when i googled 'Metis ui' this is something that caught my eye... (https://github.com/europeana/metis-ui/blob/develop/package-lock.json) i don't read code so I'm not sure what it even is but it's the only thing i saw that might be relevant to what's installed?
App#2- media:: 10065 ( it doesn't show up as an app normally, just when 'show system' apps on my apps list in settings.
App#3-i think it's from when i installed TikTok on my phone but have since deleted it, but as you can see the 'musically' file was found on my phone after TikTok app was deleted.
I'll attach screenshot of what I'm seeing... Idk what to do. Can you please help me with this?

I was in the same situation with my op9 after update to 13.1 The absolute only way I could achieve proper battery life and it was from a suggestion out of the oneplus community. Factory reset fixed everything. Now I'm getting 22-30 hours off charger and up to 7 hrs Sot. This will fix your issues as well. It stinks but is what has to be done.

Generally, the recommendation is to factory reset after OTA. Sometimes bugs pop up and factory reset fixes them. I have had a few myself lately. Anyways, if it still doesn't fix your issues, I recommend to use MSM Tool to revert back to factory firmware. It will take you back to OOS11. You can then OTA all the way upto latest one. Then do a factory reset and start using the phone.

You could first try to keep device plugged in and charging 30 min to an hour after it's completely full charging to optimize apps See if this works before having to reset device .

I've had it at a full charge and it will last a little longer but all my apps are still running in the background. And it takes so long for my fast charger to charge up my phone too. I was hoping i didn't have to factory reset but... I guess if it's the only thing that can be done for this. I've had to resort to fingerprint locking every app to see if would stop the problem. It didn't. Well, here goes nothing. Time to backup my data. I'll come back after my reset and update. Thank you for your help guys!

If you only started having these issues after updating to 13.1, then its best you do a factory reset. Its not uncommon for weird issues to happen such as battery drain. I once lost the ability to use 5G after an update and a factory reset fixed it. If you believe your phone might be compromised, well a factory reset will fix that too.
