[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.

[Q] Phone, contacts and messages keep closing

I have Galaxy S with Android 2.3.4 JVR and it works like a charm - with this one exception: sometimes (too often) phone, contacts and messages (sms) keep closing. This happens usually within a second or two after opening up them. There's no force close message, it just returns to the home screen without any warning. If I reopen it, it usually does the same a couple of times, but eventually I get it to open.
At first I thought this must be a memory issue. However, I have Autokiller installed (my phone is rooted) and I have usually >100M free memory. Then I thought it must be Autokiller killing the dialer, contacts or messages apps. BUT: this happened also before I had Autokiller installed, so it can't be that either. The strangest thing is that I tried installing GO SMS Pro and GO Contacts + Dialer, and even they do the same thing occasionally (close immediately after I open them), so it isn't a problem with apps either.
I am bedazzled here, could somebody please help me? This starts to get really annoying, since the dialer, contacts and messages are the feature you normally use most in your phone!

I have the exact same problem! Somebody, please help

the phone app and etc. seem to be corrupt or something
try reflashing.If you keep getting the problem then revert back to your previous rom =/

Is there any way to try to replace only the phone etc. apps without flashing the whole rom?

from my experience no but you can try replacing phone.apk sms.apk etc with the previous rom's apps

The funny thing is that I have a stock 2.3.4 JVR, so it should be stable.

Plus, did I mention that this happens only sometimes? Sometimes they work ok. But this happens often enough to be annoying. You know, when you would have to make a quick phone call you have to open the phone app like 3-4 times, only then you're able to make it. I wondered if the the problem could still be in the dialer, contacts and messaging apps even if the problem occurred only sometimes?

In addition, the calendar app has done this a couple of times. Could it be that there's a conflicting app that's causing this? If so, do you have any suggestion what it would be?

Autokiller made my phone do some really funny stuff. After installing it i was having random reboots and apps crashing so i uninstalled and problem solved. You said it was happening before you installed it though so im just guessing that you need to either wipe cache and dalvik then reboot or do a full wipe and reinstall of your rom. When you do the full wipe go into mounts and storage and wipe system too

Hi and thanks for your comment. What are the effects of wiping the cache and the dalvik cache? Do I lose important data? Or can I do it safely? Sorry, I'm a bit of a n00b with android. I suppose you wipe the cache in download mode, right?

I experience exactly the same issue as you-though I am on stock jvu.I come from 2.3.3, stock as well, using chainfire root both times.
Sometimes phone contacts and message s close immediately after opening them, often several times. and sometimes everythings fine
here you can find some information about dalvik and normal cache wipe..your data will be safe-only first boot will take longer.I will try wiping now, too-reporting back then.
Edit:
For now wiping seems to have worked well and fixed the problem here..I need some more testing though-will keep you up to date here
edit 2: damn! The issue's still there.anyone got more ideas?
G'day!

I have the exact same problem with JVU and I had this problem with 2.3.3 but less frequent. I have no choice but to reboot the phone when it happen. I suspect it's caused by one of the widget (email and Go weather) that I put on the desktop. Going to remove the two widgets from desktop and see if it's help.

Okay, that sounds interesting - though I am not sure wheter a widget could cause this...
I am still running JVU but now with Galaxian Kernel instead of Chainfires root Kernel - flashed with SGS Kernel Flasher and still got root - and it runs very stable and fast 'till now. No more closing of phone, contacts and messages so far -.- since 2 days.
I'll tell you when it happens again, but so far it seemed to be a kernel issue for me...

I've been having the same issues with my Samsung SideKick 4G. messages would keep closing as I was typing them, I would lag and the key I pressed would "press again" like 15 more times, sometimes I just couldn't open a conversation, other times I couldnt answer phone calls cause the UI lagged.
That was all on stock firmware, and I got fed up with it so I tried to flash a custom ROM on it, and before I did that I had it OC'd to 1.2GHz which was actually pretty great. Needless to say, I screwed up on flashing the ROM and now I'm looking for firmware to odin back to stock. =\

[Q] Can someone please look at my logcat?

I rooted my Nexus 5 about two weeks ago and I'm new to rooting so I don't know much. Anyway after my phone was rooted my apps started crashing. It happens most to twitter, and i feel like the longer I'm on an app the more likely it will cash. This also happens to Reddit and several other apps. When this happens first the app freezes for about 5 seconds and then it proceeds to crash, where it then restarts my phone. And it happens about every day... maybe once or twice a day. I used cyanogenmod and I reinstalled the rom but it still freezes, then crashes.
[Edit]- changed logcat to show E/

How did you root it? What method? Rooting alone should not cause those problems

If you used the dalvik/bionic enhanced patch, make sure to use the separate patches as the dalvik one has a extra file that is needed for cm based roms... wipe the dalvik cache too

Camera freezes?

Am I the only one with stock 4.4.2 whose camera freezes?
I've been battling the problem that if I use the camera on the Nexus 5 it will sometimes freeze the phone. It may happen after a variable amount of pictures are taken. Suddenly the phone freezes and only a reboot will get it back to normal. I've asked in this forum without success and then found this

Any solutions anyone?

What's your phone setup? Are you rooted with a custom ROM?
Sent from my Nexus 5 using XDA Premium 4 mobile app

Rooted, stock 4.4.2 ROM.
Nova prime launcher.
No syncing on anything.
Use xprivacy, AFWall+, gravitybox. (but all 3 disabled with no improvement).
Camera is essentially unusable because of need to reboot every few pictures. Screenshots in my other thread.

dont disable the exposed, delete it(remove everything xposed completely), reboot, then try your camera

I would hate to do that because I really like xposed. But I'll make a nandroid backup, and then do as you say. If it's no better, I could always restore the nandroid. But nobody else has noticed any connection between xposed and Google camera. I "believe" the problems started when I updated to the latest camera update. Wish I could find the pre update camera app.

xposed causes many many random issues that are undocumented. for many not a single issue, for others its like a phone full of gremlins.

Well, tis done. I'll see if the camera behaves. It takes time for it to act up....
Fwiw, I've used xposed for quite a while and the camera freezing only started about 4-6 weeks ago. Maybe it was a recent update.
I uninstalled xposed. Where should I look for files to delete to ensure a good test?

honestly, i dont know. i have never needed or been willing to use xposed. an uninstall and a reboot should be fine(dirty flashing your rom again would be best, but i think it will be fine without). just give it some time to test. if its not xposed, restore your backup and we will look further.

I'm afraid to say anything, but I think uninstalling Xposed did it. Will wait longer before breathing a sigh.....
Thank you.

Question OneUI crashes

Does anyone else have crashes for oneUI ? Fort me it happens like twice a week on my exynos model.
I'm so disappointed with this phone to be honest. It's stutters now and than and to many crashes in various apps.
I'm assuming must of it is due to Samsung chip.
I have also whacked for nightly restart even thought it's stupid i think.

Did this happen from day one?
If not it's likely an app, update or settings issue.
Still that's pretty unstable... it could be a hardware issue.

try factory reset with disabling of trashy preinstalled apps (disabled 144 on mine ), then install your apps (not restore)
adb app control

It wasn't happened on mine ( SD variant). Try to factory reset the phone, download and re-install all of your app instead of restore them (even with the phone setting). It may help to solve issues

I appreciate the tips but seriously guys, factory reset and redownload of this many apps i have is like a weeks work! I only download the stuff i use (and 99% payed apps as i hate ads). Not to mention i might loose some data thanks to how Android save data. This is not 2010. I hope modern phones are more stable then that.
If this was iPhone then i could simply restore easy but with Android its not as simple.
If there is no other way i wait for some more samsung firmware updates.
It has not happened this week so lets see.
I notice some specific apps are specially bad like LinkedIn hangs allot. Tapatalk wont work even with this forum and gives error. Maybe some of these apps make the launcher go nuts....

Try using a different launcher, to see if that stops the crashing

No thank you. I like Nova but i really like to use stock now so i get all my folders and settings saved properly
But i might go to Nova again. It has so much great tweaking...

Yes there has been 2-3 updates since last time and so far it has not crashed so it seems to be fixed. Cheers
