Poor performance

Hi,
My partner picked up an arc in the week, and we have both noticed the performance is rather poor on occassion. Sometimes loading an app will take ages (10secs), or even the app drawer will take a long time to open or to exit back to the home screen.
We also had a low memory warning from tasked and upon checking there was only 16mb free with nothing obvious taking up the resources.
Has anyone else noticed this? Firmware version is 3.0.A.2.184

Did you try to do factory reset? this helped for some people. My arc is really fast and everything works great.
with low memory you mean the internal storage? this happens if you installed to many apps. I always move games to the SD this saves some memory

Don't really want to do a factory reset a few days after getting it (I know it might help, but it's more the principle...)
Most the of time it feels pretty snappy, but every so often it just seems to lag for a while.
As for low memory, I was referring to RAM not storage. Internal storage has something like 170mb free, but RAM seems to be constantly running with ~60mb free and dips down to <20mb even with not much running.
The only things that should be running in the background are twitter, facebook and Wordsfree.

i have degraded performance though not that worse, i suspect mine was caused by running background app like yahoo messenger, facebook, g talk and possibly go weather.
also change home to go launcher. this may not be correct, but with default se launcher certain app get killed faster (maps). also opera mobile contents somehow get purged a lot with go launcher (note : this may not be true).
currently available ram drop to 32 or less in hours while previously it took days (or maybe never) to drop below 100 mb ram. sigh..

Performance on Go Launcher was woeful for me, but with the SE launcher and Launcher Pro it seems fine, well aside from the issues in the OP anyhow.

sigh, se default screen protector and input keyboard are slippery. to op, i see that only facebook is what we have in common.
i've completely log out and remove fb data but still it run in the background. any advice to stop it from running (non rooted phone please)?
does anyone know if freeze -ing app stop it from loading or just froze it in memory?
thanks for your input on go launcher and quick reply.

I'm always like around 150MB free RAM, i don't use any kind of task killer nor do i kill anyting. there are 20 apps running right now. The phone can lag when syncing (you see the syncing icon then) but in overall it works really smooth.
I think there is something really messed up. i think you will be beter off with factory reset. if you have root you can use titanium backup.

Funny how all of us jump in saying do.a factory reset or reinstall this or is got to be a app running in the background lol. Phone is beautiful and all but factory ROM is crap! I installed the NAG rom and seems to be helping a bit but yes stock launcher lags crazy. I hate when u have to do so much **** to a phone to make it run better. That would be us but a average person that buys this phone for daily use with no idea of RAM or a different launcher would say **** this phone. To slow. Lol. I love the camera that's why I'm putting up with this. I have two lines tho. Using a Thunderbolt too. Yes it is faster. Snappier.

hmm lets see.. do you have timescape ui on? if too many accounts are synced into the timescape it can cause lag...

One of the programs that's running in background might be messing up. Go to running service and kill all the custom applications (NOT DEFAULT ONES) then see how it works. Less than 20MB RAM will cause performance issues. Uninstall software that you don't use much. Uninstall task killer software if you have one. I find that unstable. If that didn't do the trick then as said before Factory reset would be a best option.

srry but i don't agree with this. A lot of people used my phone to see how it was before we had root. even iphone4 users said that this was snappy phone. i;m with tasgr86 on this one. don't over react. The phone can slow down when syncing and this happens with all android phones.
if you read here http://forum.xda-developers.com/showthread.php?t=1077292 you will see that factory reset can do wonders.

I have 2 Arc, My 2 bro have also Arc. None of my bro visits mobile site or XDA to get knowledge about phone, but they have no what so ever problem with Arc. One of them came from iPhone & one from Galaxy S.. Phone is smoot, no lag & very fast...

I'm watching this forum for a long time, and it's amazing how much the community split up - 80% of users love the phone and have no problem with it, while 20% moan about performance and etc.
**** happens; you maybe got a phone with faulty hardware, or something else, w/e - do a factory reset before crying how crap the phone is, common sense really.

My phone doesn't lag or does the browser and ram always sits over 100mb

I just rebooted my device after 40 days of continuous usage.
Arc is brilliant.

he didnt factory reset,,, he re installed the rom... i did the same .. i still have to reboot at least once a day.. phone cant handle me.. i text a lot .pictures taken and web and also google music.. gets laggy after a few hours .. this is not my first or second android phone .. there is something on the ARC that eats memory and wont free it up its like the phone performer slowly die....and the only way to revive it is with a reboot .. still love it tho.... dont mind rebooting once daily

have to agree that something is definitely leaking memory, which only seems recoverable by a proper reboot.. (using the button on the top and not reboot widget..)
trying to figure out what is causing it isn't proving to be a simple task..

I had a similar issue and as much as it might be against your prinicples, I did a factory reset and the phone is now fine. It's much easier to flash an android phone as all my contacts are synced with my google account, most of the apps back up their settings to the SD card and all of the apps you've bought you just redownload from the marketplace, hell google even have my wpa key to get on my wifi. If you aren't prepared to reflash then learn to live with the lag but I think you would find it will help a lot

just a thought, perhaps browser cache put a lot of strain on flash chip? i know people said latency/fragmentation is not an issue on them, but again i've seen many slow down/unresponsiveness on worse scenario.

WTF with the ram

i can only open about 3-4 app before my ram is full and its forcing to closing app . seriously ? wtf is this .
i feel like this phone is worse than n95 .
if i open a web page one youtube link and i still have in memory my message app it will start closing app and sometime it even close the Touch wiz widget so they have to re appear and load for 4 second . i cant believe they only putted 1gb of ram with all there touchwiz bloarware.

Ram issues
Check what apps are running on the background, i would check primarily things you log into that are always logged in like FB, Gtalk, Skype. although even with all those running you shouldnt have issues, maybe try doing a cache and dalvik cache wipe reboot and check changes.
MY BEST FIX is rooting, flashing an AOSP based rom that normally for me they use 350 to 400mb on a normal basis instead of 550-600mb in a sammy based rom.

mine is usally 800-1g and im constantly clearing memory. I dont get it either.

I agree, I just opened every app i have and went up to 1.26gb.. and when i have no apps open it jumps from 800-1gb on its own.. so i guess its all in the system that takes up most of the space

Jeez 1gb is more than enough

Problem is with the Samsung bloatware. Kies, Remote Controls and all those other services. Delete kiesexe and freeze the Samsung crap inc SVoice..
I see no need to sync to Samsung and Google. The Google services are enough.. The Samsung store is only worth unfreezing for those free offers. The four tracking services ain't needed etc I use Avast to do that etc.
Getting 285M free apx after bootup, same as ICS, on 4.1.2 now. 12 widgets, FB, G+, Fancy widgets, Jorte etc
Also make sure not to run supercharger. It kills multitasking!

Disable all the Bloatware or freeze it using link2sd.

My 2gb i747m really makes use of the extra ram. It not only can handle 50 background apps with stock rom as apposed to 15-20 for the 1gb version (assuming there is enough ram), but it will boot with about 1.6-1.7gb available, about 700mb used, and 1gb free, and will use memory up to about 200mb free before killing apps to make room for new apps. Bottom line, it multitasks like a S.O.B. My opinion based on 2.5 years Android experience...is that 2gb ram helps big time...especially if you do not optimize your system.
If I had the 1gb version, I would consider a lighter rom as some have mentioned, but also the V6 Supercharger app with specific settings to allow maximum multitasking while remaining stable...which might take some experimenting. I would install Titanium Backup Pro and freeze as many non needed apps to prevent them from loading at boot and using up precious ram. Also, for some apps, I use AutoRuns to prevent them from loading at boot time.
Also remember...that some apps will stay in RAM when it's plentiful. But other apps are programed to allow Android to kill them after a certain length of idle time when they haven't been used.

Ram management is fine on the S3.
If you are not happy with it use a task killer, custom rom/kernel and/or supercharger v6 script.
Also if your ram<100 then you should start making complaints.
My free ram is at 120mb-160mb and i'm happy,no lags,no slowdowns,nothing at all.
Android preloads apps in memmory in order to open faster when we launch them.
Free ram really is wasted ram...it cancels multitasking and if you've bough a 600$ phone and can't multitask with it then you're worth of your fate.

The fact that an user has to get task killer and manage memory by him own: FAIL!
I know android pre loads stuff in memory, but it got the priority all wrong.
Why does it keep killing msging, phone and the GODDAMN launcher .
While it never kils the stupid stuff like "Google Book mark Sync", unless you freeze it.
There's no denying that 1gb has crippled S3 badly.
You can claim "Free ram is wasted ram" and throw down links, but at the end of the day it is giving me a bad experience.
Case in point:
1) Launcher Redraw:
Two points to it:
->Bad priority (I'm not sure if it's either a Samsung fault or Android; OOM 6 isn't the way to go).
-> Less ram.
The fact that browsing through play store for 15 mins and then hitting Home button results in launcher redraw is pathetic.
Less ram is the culprit( atleast one of the).
On such an expensive device this is just EPIC FAIL.
Sure we can do Super recharge and try removing the bloatware, but these are quick fixes and doesn't get rid of the main problem.
Not to mention not every one finds all this stuff easy.
The fact that you have to do tweaking on the 'supposedly greatest android phone' to make it work smoothly is an EPIC FAIL.
Custom Roms for an device as expensive as S3, should be there to enhance functionality and increase features. Not to make it works the way it should have out of the box.
2) Sh**ty Multitasking:
Trust me, my iPod touch does better multi tasking that S3 for day to day experience. (I am not an apple troll, btw)
And it doesn't even have a true multitasking and the specs are no where near S3.
When I pause a game, and resume it after an hour it starts from exactly same place . Try that with S3.
Try to use your phone when many apps are getting updated and notification bar is constantly changing.
It'll lag the hell out.
There's no defending to these points.
This is where Apple excels , by giving user everything perfect from out of the box.
Sure you can't do much, but what ever you can, you do it smoothly.
What makes me sad is that Samsung is so close to it, yet they screwed the experience.
And I'm not even going to talk about Contacts and Phone apps.

Sorry but this is complete and utter drivel. Stop quoting websites and Google and start wising up.
If you have a game that needs to run and it uses 100mb and the phone has no free ram it kills something else.
This would be fine if the phone loaded the apps quickly but it doesn't.
Custom ROMs do not fix the lack of ram and neither do any of the memory management scripts.
My phone has around 200mb to 300mb though and it still loads and reloads phone and messaging and browser randomly.
Sgs3 is useless at memory management and anyone who says otherwise is living in a dreamland.
No lags and slowdowns is just blatantly not true as your messaging app and phone app will frequently take up to two seconds to load if you are using any Samsung ROM.

True that.
I have no idea what is stored for 500-600Mb ram if not the important things like Phone, Msg and Launcher.
Useless stuff.

It is just marketing and business politics, Samsung knew that 1GB is not at all future proof but that is exactly what they need so they can sell the Note 2 and the i9305.
And still they sold over 30M i9300 devices.

Man, Android loads that stuff itself based on usage, OOM settings and Minfree values. The other stuff is services that need to run full time so that Kies sync, Location and other Samsung bloat that is really not doing anything most of the time.

Ya I know.
I wonder how can the most important thing, launcher, has an OOM of 6.
Stupid really.
Is it a fault of Android or Samsung messed it up.
In all the galaxy nexus videos I've never seen launcher redraws.
So maybe Samsung messed up for whatever reason.

that remark has been misused greatly by people that can't code for ass and fail at memory optimisation.
It was originally in reference to the Superfetch feature in Vista/7 storing frequently accessed data in ram for faster application startup. It wasn't meant to be applied to applications that use huge amounts of memory for no good reason.
much of Androids poor memory management is Java related, who knows, maybe Google will get a clue and dump the Dalvik VM eventually for a native operating system.

you could consider a debloated and slimmer touchwiz rom from the android development section and pair it with one the great kernels also located here. might get the results you want plus be able to keep touchwiz, if thats your thing.

High RAM usage is a good thing not a bad thing. The whole point to RAM is to keep stuff in it so it doesn't have to be reloaded, which causes lag. What are you trying to accomplish by clearing the memory?

That's normal, and infact good.
When you close an application, it leaves a bit of footprint in the RAM. So when you open it the next time, it opens faster. Incase the RAM starts running out, android removes the earlier apps from it.
Stop blaming Sammy for just about everything.

Might wanna check what apps you are using and have installed. Uninstall apps you don't use etc.

If you have root you can freeze apps you never use and I disagree it doesn't affect the system performance. On a boot up just about every application loads into memory and that's plain stupid, since most of those apps I never ever use. I was actually shocked when I looked at application manager and everything was loaded into memory. It was main reason I rooted my phone, to freeze all the garbage and bloat on my phone. You can also delete some of the stuff, but it gets little complicated if you delete wrong app and then other things don't work no more. I don't know if they load all programs into memory because of "just in time" compiler, another idiotic idea, why compile program once, when we can compile and waste time, every time we start the program. When new, my phone would use about 70% of memory right from the boot and would go to 90% over time, now I freeze just the most obvious stuff and start at 40% memory load. There is a spreadsheet listing all apps, what they do if they can be safely removed, it could help you get better control of your phone.

I've just recently installed boot manager(requires root + xposed framework) to combat this very problem. It doesn't stop system apps from starting just user downloaded ones. TBH I haven't noticed any effect on the battery or the speed of the phone. Just when I restart, the phone has more free memory.

Since Google, just like Crapple thinks all their users are idiots and should be saved from themselves, yeah you need to root to just do anything on your phone. You can go to Application manager and force close programs you don't use without root but:
1. you need to do it every time phone starts one by one
2. some programs will restart by themselves anyway
When you freeze, you do it once and that's it. ROM Toolbox has pretty much all you need.
As far as 4.4 goes, yep you may get some RAM back but pretty much loose access to your SD card, if you have one, something like going from shower into the rain

KK introduces new permission for SD card usage that breaks writing to SD for most 3rd party apps, you can fix it if you're rooted or run custom ROM, like above poster, but I don't think there is a way to root KK without tripping Knox flag and so you may be loosing your warranty.
I'm rooted on 4.3 and my flag is x0, so for me this is the way it will have to stay.

I've just recently installed boot manager(requires root + xposed framework) to combat this very problem. It doesn't stop system apps from starting just user downloaded ones. TBH I haven't noticed any effect on the battery or the speed of the phone. Just when I restart, the phone has more free memory.

Just to add to this.
Here's another app I've been using to clear ram.
Advanced Task Cleaner Pro (doesn't require root)
https://play.google.com/store/apps/details?id=com.bright.taskcleaner
The advantage this app has over the regular way of clearing ram is that you can create an auto-kill list, which will stop apps from reloading back into the memory after being killed. It will show system as well as user apps and processes currently running.
Digging through the settings there's also a setting to clear ram on system startup(non-root alt to boot manager)
I myself have never got the "full or almost full" memory notification, so I quess I've never maxed out the ram. I think most of these memory/app killing apps(including the one above) are aimed at low and middle tier mobiles which don't have sufficient memory to cope with multitasking and background processes, without stuttering and slowing to a halt.
Since my battery life is good, and I'm more than happy with the phone's speed, I haven't got a real need to clear the memory all the time. I have a habbit of closing apps after using them, although leaving apps in the background and/or not clearing memory after closing will result in faster opening times. There are quite a few claims that these ram killer apps save massive amounts of battery and what not, from my end I don't see this, although its important to check for yourself and come to you own conclusions.

Cleaning apps

Hi,
recently I bought used LG G2 and I got a little bit disappointed. Since I left androids behind me 2 years ago because of lagging OS, I went to Windows phone and got blessed. Phone worked without any lags.
Anyway, since I came back to Android I felt that lag again. It's not really hard lagging since it has got 2GBs of ram and quad core processor, but still... So I have decided to try out some cleaning apps like Ccleaner, cool master etc. So that makes me wonder, are these apps really useful? I have read that they are good for closing background apps but that process drains more battery. I would like to keep my phone without lag and with highest battery life. So should I install these kind of cleaning apps and if yes, which ones do you recommend? Also same question is for battery apps, should I install some of them and which one? Thanks

all these apps do nothing.i personally use greenify that works best but u need root for that

Yeah, I thought so... Seems like they are just drying my battery.

Any more tips about this topic?

flash dorimanx kernel.. use system clean up, and sd maid.. you can try purify too..

If i'm not wrong, this requires rooting my device. I would like to avoid it, I'm familiar with rooting, but still I would like to keep default things on device. Let's stay on the topic, do these apps their job good or bad?

If you root, theres endless possibility of getting the best out of your device.
Since you dont want to root, download greenify and purify.
Greenify for hibernating app cause apps runs in background even when u close them from android app manager.
Purify for managing app to autostart.
Use them both and post back with results.
Also get rid of unnecessary preinstalled app , search " how to remove bloatware" on xda .
