UK SIII Unbranded with Jelly Bean - Noticing performance is decreasing

Updated to the official OTA JB update a few weeks ago, and at first thing seemed great. The UI looked smooth and things seemed to have an increased efficiency. However ive noticed over the last week that things have been going wrong.
Delays opening and exiting apps, dialler being even slower than normal ( i know this has been an issue for others).
Looking at the device's ram usage its been at the 800mb mark, which i thought was quite high.
Anyone else been having similar probs?
Cheers

Try wiping cache from CWM.

should of also mentioned im unrooted.
is that still possible?
thanks

The stock recovery only has a factory reset option (deletes your data and apps).
Alright, did you install any new apps before the problem happened? Any dodgy widgets? What's the service using the most amount of RAM? (Settings -> Application Manager -> Running -> Most app using ram, look at the one with the highest MB's).

One its a question .
Two i would backup data and factory reset first .
jje

largest running apps being:
Settings 67mb
Google services 22mb
Samsung Keyboard 21mb
Viber 13mb
Facebook 17mb
The rest are under 10mb

Same happened to me, I factory reset the phone and it runs too good to be true. Also disabled some bloat in app settings,not sure how much difference its specifically made but the phone flies.
Additionally there are 4 settings that will speed up your phone, allow dev options to be on, find force GPU rendering and turn it on. Then above that there should be 3 settings that each allow numerical settings, set each of the 3 to 0.5 to reduce the time that your phone loads up advanced displays animations.
You're welcome.

From what I remember force gpu rendering causes apps to use a lot more ram. Could be wrong but it will probably be an issue for those who complain about low ram.

I know it might seem a bit obvious but have you switched Power Saving Mode on?
Because for half a day I was convinced something was seriously wrong and thinking the worst until that face palm moment when I saw the icon lit up.

I definitely notice an increase in performance with it on but haven't noticed any adverse affects like more ram consumption, in fact the only problem ever was that the app androidify didn't work

Scrap that, having just tested, I experienced significant less RAM usage and a better fps with force GPU on, perhaps you heard that out affects the battery negatively? I don't know but it works wonders for me

well before i could tinker and try out the suggestions here it seems like my phone has had a dose of Sudden Death syndrome.
Wont turn on, charge or anything.
Anyone else had this in Uk and could tell me process of getting a new device or repair?
Thanks

Does this actually reduce the loading time? As far as I understand this setting just plays the animation at double speed, so it makes your UI appear snappier.

Minimally I assume because it's not processing the animation so much. In all honesty I can't give a definitive answer though.
I think forcing GPU does though because your processor is free top load up all the back ground processes while your GPU loads the visual aspects, efficiency is always the best way and most things on jelly bean should be optimised for it.

[Q] Nexus 7 running incredibly slow

My 1st generation Nexus 7 started running incredibly slowly - to the point of unusability - around the time I set up a second user profile on it for my fiancée. I'm not sure if these two are connected, however we are using the same two-profile setup on our Nexus 10 with no issues.
N7 was running stock, and I finally had enough of not being able to use it so I wiped and installed the latest nightly of CM which I'm running on both my N4's and also the N10. Since flashing CM on the N7, there has been little improvement in the speed of the device.
I'm very hesitant to put it down to a hardware problem, as it seems very unlikely to me. I think it's far more likely that there is a misbehaving app or service that I had before, and re-installed since flashing CM and is continuing to cause problems.
Looking at the battery usage graph, I can't see anything obvious that stands out. Is there any other way I can find out if there is a misbehaving app or service that's causing this problem? Do you have any other suggestions on how I can narrow down what the problem may be?
Many thanks.

How much memory do you have still free on it? It's a known fact, that if you go low of memory (<1-2GiB free) the system is slowing down very much.

Are you talking about storage space?
I have 2.98GB free right now, apparently.

..

Yes, storage space. There was already a thread some time ago where especially people who had bought the 8GB version noticed a massive slow down after they had installed some apps and the free memory went below 3GB(!) (I remembered wrong, it was not 1-2GB, but 3GB). The thread can be found here

use clean master to clean your cache and kill tasks.i do it constantly so my device runs speedy

Try to get more than 3GB of freespace then try lagfix(fstrim) free.
Has ran into this problem once. but after done booth solutions above now my N7 is running as smooth as Brand New again.
P.S. Before I've found Lagfix(FStrim) I'm use Forever Gone and it work just as well as Lagfix did. except Forever Gone is take much longer time than Lagfix to finish its job.

[Q] Memory Leak? Avoidable?

Just decided to use my Nexus 10 after about a day or two of inactivity, and I noticed it was real sluggish. Went over to Running apps, everything shown there is Restarting, and there is only about 77MB of RAM free.
I've had this happen a few times I believe.
Is this scenario avoidable in any way?

Free RAM isn't usually a problem: Android will cache things in memory to help them load faster, so normally seeing <100mb of free RAM isn't anything to be concerned about, and will not affect performance at all.
The sluggishness and "restarting" services sound like something bad, though.
First, make sure you aren't running any kind of automatic task manager/killer. Next, after restarting your device, keep an eye on that running services tab in Android settings: apps. See if any of them seem to be growing in RAM use disproportionately to the others. It may take a few hours to show up.
I suspect you have one bad app with a leak causing low memory to force the other services out of memory.

Even after caching and such this tablet should normally have 400-600MB of free RAM though. The low amounts definitely come from a memory leak. Right now the general consensus is that it cannot be avoided because it is a problem with the GPU driver. How much truth there is to this I dont know. I do know that I myself did not have performance issues or memory leaks when I was back on 4.2.1 running CM10.1, so I still feel like something in 4.2.2 introduced a memory leak.

It is normal and expected for free memory to dip lower than that during normal operation. It is simply inaccurate to tell people otherwise.
I would caution against claiming something is "definitely" anything with so little solid information.
It might be that there is a memory leak, but it is much more likely to be a user app than a kernel memory leak until there is hard data saying otherwise. As of now there is only one highly subjective user report.

During operation yes, but when you pick it up after days of the tablet idling with nothing running?
There is plenty of solid information if you have looked around the development threads with all the activity trying to pin down the memory leaks everyone is having, to say one doesnt exist just shows how little you have been getting around the threads.

Nothing in Recent apps, I had all my usual apps installed. Most of the time when I'm doing nothing I have hundreds of MB of RAM available as free space.
No Task Killers either. Couldn't even open a game I had (would instantly go back to launcher, no FC message) or take a screenshot even.

Just my personal experience, but I have owned my N10 since December and frequently let mine idle for days and have never come across this issue yet. Memory on mine is usually above 600MB everytime I check it in the Apps setting, I don't think I've ever seen it go under 100 since I've owned it, and I do go in there a lot to force stop certain things that autostart. I am leaning more towards what ZanshinG1 said that its a rogue app installed thats eating it

For the record surfaceflinger will eat about 100 megs per hour of video when you watch YouTube through chrome. I've duplicated this on stock, CM, mrrobinson AOKP, and raspbean. At about 600 megs the tablet will start misbehaving, closing apps, being sluggish, keyboard won't come up in chrome when you go to the address bar, etc. If you can stand to wait it will eventually reboot usually when idle in my case. Oddly enough the YouTube app doesn't produce the same results on the same video.
The usefulness is debatable. The facts are not.

Hopefully ROM dev's will add some newer AOSP commits to their ROMs too, such as:
Fix a minor leak in dvmCreateInlineSubsTable (commit to aosp)
minor leaks caused by failed initialization in JNI_CreateJavaVM (commit to aosp)
Fix a minor bug in dvmCreateInterpThread (commit to aosp)
Fix some leaks in VfyBasicBlock & BitVector (commit to aosp)
But it is probably a rogue app.

Chrome?
So for s&gs I installed naked browser and I'm not seeing the climb like I did with chrome. After about 4 hours of YouTube it went up 4 megs instead of 400 megs. I just saw another user seem to confirm this too.

I don't watch videos from Chrome, and it wasn't open at the time either (I may of opened it earlier before I noticed the memory leak, but I know I swiped it away from Recents when I was done with it). I didn't use the YouTube app either.

Had it occur again, although it wasn't "as" severe since I was able to load a game and take screenshots this time; performance was definitely slower though...

Maybe run PS in terminal the next time and grab a screenshot. Then after reboot or return to normal do it again and compare usage?

I have my tablet reboot every night at 4am with Tasker-Secure Settings plugin. Maybe not a fix for the issue at hand, but enough to make this problem go away permanently and reliably.

Easy fix: don't use trash roms like aokp or cm
I personally use team eos and ktmanta and the system runs super smooth with no memory leaks what so ever. After 32 hours if I clean all apps I got 600 or 700 mb free.

Wow. Talk about trash talk.
I've never ahd this issue on AOKP or CM, have on PA... I did enjoy Eos when I used it but found RootBox had the features I needed. Then again... I reboot every few nights typically. My mom leaves her Nexus 7 on for weeks on end with no issue, but its not a 10.

I don't consider rasbeanjelly trash...

I think I've run into this bug once, after a couple days of usage, likely mostly inactive without charging. I noticed that everything I tried to do was really sluggish and once I saw all the apps restarting in the built-in task manager, I figured something was seriously borked, so I rebooted the tablet and it was back to normal. Given all the other stability problems others have reported with this tablet, I'm glad just a very occasional reboot like this is the worst of my problems. :victory: I'm running stock Android 4.2.2, with only a handful of apps installed, probably more default apps uninstalled than apps added.

Nexus 4 uses only 512MB???

Hello
I'm, still shocked.
Today I've upgraded to kitkat from 4.3. Everything stock and OTA.
I've noticed that heavy apps are often killed from RAM, so that when I open them again it takes a startup time as if it were the first time.
Then I have noticed that regardless of the apps I open, my memory usage is always around 500-550MB leaving 1300MB free!!
WTF.
Chrome is the most painful example.
1) Open some tabs in Chrome.
2) Then open some heavy apps, like play music, hangouts, youtube and calendar (maybe you should open some more to fill as RAM as possible).
3) Then open again Chrome
4) Chrome will reload tabs since it has been re-started again
If you have a look to the memory usage you will see aroun 500MBs. What about our 2GB!!!!
Being chrome so heavy, memory management decides to kill it each time, delivering a terrible user experience...
Any idea? Any solution apart from restoring 4.3???
Thanks a lot.

No kidding I'm still surprised. In the beginning I was using 800mb but now it sits at 475~mb ram usage. This is ridiculous and I'm using the heck out of it. On the downside its kicking my hangouts out of memory. When I launch hangouts, it takes a while to start up.
Sent from my Nexus 4 using Tapatalk

It looks like the system is trying to limit itself to use only 500mb. Maybe that's what Google meant with Kitkat being more optimized? so much for 2gb ram...
Sent from my Nexus 4 using Tapatalk

Now you mention it I am noticing a lot of apps restarting now. And hangouts is a prime example.
Sent from my Nexus 4 using Tapatalk

So does this mean there is now no benefit in having 2GB ram? Kind of like having a laptop with 8GB ram running a 32 bit operating system that can only see 2.

Per Google, KitKat is designed to run in older phone too, even at 512MB RAM can still run KitKat. For example, Nexus One which has only 512MB RAM and still able to run KitKat, not stock ROM per se.

are you sure??? I tried it on purpose. I opened asphalt 8, Dragon Realms, turned the music on on the Play music, Hangouts,Facebook, Google Currents, Chrome, and music tuner in capture mode, and I am able to switch between them seemlessly. I opened settings and it jumps to 719 MB RAM.
On the other hand I faced some weird lag on my N4 these past days with KitKat. I must say I already forgot how laggy Android was long long ago, and now I am forced to remember it.....
Stock 4.4, not rooted yet (for observation purposes)

Even my tapatalk app seems to get killed off all the time.

Hmm maybe it's not only using 512mb... but mine reaches 1gb and kills stuff off relentlessly.

I just loaded around 11 apps. After switching to the first app; it refreshes. My ram never reaches 1GB.

Could it be something kernel side? I'm on faux kernel.

Now that u mentioned i checked on my phone .. i am on stock rooted.. my ram doesnt go above 600mb howmanyever apps i open it reaches 600 mb and then starts killing them .. this isnt cool ..!! now i understand why my apps restart on me sometimes .. this is a screwup .. whats the point in having 2gb ram and not getting the benefits out of it .. kitkat is supposed to support 512mb ram .. not make the max limit of the phone 512 mb .. hope this gets solved!

Can someone on stock do a backup then test faux kernel or some other kernel see if it's the same? As i sai mine reaches about 900-1000 before it starts killing off i still think this is a bit low. 2gb of ram so why not use it it's being wasted.

In stock is confirmed. Sometimes you can get up to 680-700 but then in some seconds they get reduced up to the 500 again...
A friend of mine has a Nexus 5. He did the same test and he get stable usage of 1Gb and no tab refresh/hangout re-start..
It is clearly a Nexus 4 issue. Final proof:
https://code.google.com/p/chromium/issues/detail?id=322336
They say that it is logic management problem of android... Chrome has nothing to do except being so heavy... But it happens with lots of others...

I can also confirm this
I can also confirm this on Stock Nexus 4 Kitkat (Root).
I did not notice this before, since apps were loaded so seamlessly and quickly from cache (Is it because I'm using ART?), but Chrome gave it away since the tabs are refreshed.
It starts caching apps at ~800+ MB usage till it reaches ~500 MB.
It doesn't bother me performance wise, but is there a way to change the memory limit other than 800 MB on a rooted device?

Do you Know any custom kernel that allows this better usage?
The less intrusive possible since stock is fine for me except for this...
Faux? Semaphore? Another?

Im using semaphore but mine is same. Hangouts gonna restart, chrome refresh and launcher redraw. Maybe Google will fix it.

i think your problem maybe related to OTA update .
i'm okay with Stock rom with factory image .
but i use franco kernel .

No wonder the kitkat makes my phone lag a lot.. Even apps like Facebook and whatsapp take time to load and lots of time to scroll.. And chrome gets stuck every time I scroll..

HOW TO - Fix Lollipop Slow Down Issues

ive been using the apps from this guy
https://play.google.com/store/apps/d...terprise&hl=en
ram booster and cache apps to sd booster
significant performance increase. im talking about no slowdowns and easy multitasking
after unlocking, installing lollipop and rooting
pretty significant increases. cannot complain at all.
dont have any slowdowns on my other 2 devices (n7 2013 and n6 on vzw) so cant compare to those but this fixed my shield lollipop issues
he has a lot of other products as well but i havent used them.

Woops Sorry. Here's a link to the ram Booster app then just click more apps by gejos
https://play.google.com/store/apps/details?id=com.gejos.android.rambooster

I remember the good old days of Eclair when these things used to be commonplace.
tl;dr if you're actually running one of these things and you're seeing a large and measurable change... something's not quite right.

Yes. Lollipop update. Tried factory reset, deleting certain apps. Nothing seems to help until I tried the ram Booster.

Ermm. Sounds like placebo. This isn't android gingerbread anymore and these types of tweaks are largely useless... On our high end device anyways.

If you do a search on xda, I am not the first person to mention these apps specifically. I agree that these things are mostly garbage but this one is different. I urge whoever is having performance issues with lollipop to try this.

Are you using the donate version with more options? I think I tried this app before and it didn't fix my slowdowns, but I will try again. I don't have SD card so I can't try the other cache to SD-app.
The slow downs and memory leak are so frustrating, I have to restart a couple of times every day to be able to play for an example Simpsons Tapped out. I use the same apps on my ASUS Tegra 4 tablet with 4.4.2 and it feels so much faster and there is no need to restart it every day.

nope, regular free version. i didnt even know the donate one had more options

Neither the donate or free version should provide any noticeable difference besides maybe more battery drain.

Thanks for the helpful feedback. Please try the app first and then you can comment.

I have been running the app for 5 days now, can't say I see any difference, I still have the memory leak (or what it is that causes the need to restart once or twice a day). Still have the UI slowdowns too.

http://www.androidcentral.com/ram-what-it-how-its-used-and-why-you-shouldnt-care

I'm just going to venture a guess that any task killer that is significantly improving your battery life is probably rooting out apps that are falling into Lollipops memory holes. So the battery savings are accidental...
This is not how Android is supposed to run. This hasn't been the way Android has run since 2.2 or before, the last time task killers were all the rage.
