[Q] Apps not closing properly, using up all RAM, and draining battery - Galaxy S III Q&A, Help & Troubleshooting

Hello, I'm new on the forum here. Hopefully the super smart people here can help me out.. I'm pretty clueless when it comes to troubleshooting my phone problems, but thankfully I haven't had many of them to begin with. To the problem!
Recently (as in the last week or less) I have been getting notices from Clean Master that my app MyFitnessPal is using up too much memory. What is happening is that when I use this app and I exit it (by using the back/return button), it isn't closing like it used to. I am realizing this isn't the only app that is performing strangely. Chrome and Apps Organizer are also staying open and using up RAM. I've not had these issues before, so I'm not sure if an app I have got updated and is causing problems.. or if it's user error on my end. I did a scan with Trust Go and the results were that everything was fine. That was all I honestly knew to do to try and fix the problem, other than use Google to try and find fixes for the problem.. to which I have found none. All I find are instructions of how to open the Task Manager and force stop the applications, which I already knew how to do. I really hope I don't have to resort to checking the Task Manager every time I open an app now to make sure it closed.. what a bummer.
I'm running Android 4.3 on my Samsung SIII SGH-T99L. My device is not rooted.

[Q] There are Apps in the background

Dear Friends!
Glad to be here today (after 2 days! )
My dear Streaker is here!!
As the norm is, I have been busy tinkering with the stock material for couple o days, and I will continue to do so for some more time!
___________________________________________________________
Query: There are too many apps running (background) all the time!! I kill them, they resurrect!, How to do away with that?
Solution applied: Used Advanced task killer (but, apps resurrect!)
Another Solution tried: In Settings>Account & Sync settings> Unchecked Background data and Auto sync options. (Now, they dont connect to the net, but, they still restart!!)
Another Solution: Force close (from Manage apps) .. (Still same issue!)
Now, How can I tell the apps to come up only when I call them!?
(And some other apps I want to schedule them to come up every hour or so.. like my Gmail/FB)
____________________________________________________________
And, So far has been amazing experience!!
The screen is football field sized!! (Monster! yikes Scooby!)
Digging up all old posts to read some problems faced by new users..
Current hobby: Market and apps.
Future hobby: Roms and Flash!
Thank you all for your help!
care,
Sony.
Welcome to the cool kids club! I'm in a somewhat similar situation, I got my streak just before the massive snowstorm hit. Some of those apps need to be running... if you close some of them you may not get updates/notifications, or you can shut down your phone/data connection, or lose the use of multitouch.

from what i understand, froyo is really good with resource management and there is no need to constantly kill processes or apps, its best to just leave them unless your streak is slow like a snail

How?
@rptw
So, It wouldnt really matter if there are apps running in the BG, and they start by themselves too!?
care,
Sony.
well in terms of the laws of nature (in most cases) stuff doesnt happen spontaneously so i think its safe to assume that your app that "started by themselves" were probably opened somehow either by you directly or indirectly by something else. if, however, you have a large number of apps that have started that you dont recall opening, maybe something is wrong with your software and you shouldnt try to cover the problem with a task killer.
So, what next!?

So, Now, can you or other guys here please suggest how to go to the "root" of this problem!?
Ok.
Look, these apps are open right now!
Voice Search
Email
Messaging
Maps
Astro
Assistant free​
I use the Adv Task Killer free.
(It says 7 apps killed and 180 MB free)
I open Adv task killer after 5 seconds.
and these apps are running!
Email
astro
Voice Search
Assistant Free​
and I am sure, If I wait for some more time, the other apps will join in too!
(Now it says, 3 Apps killed, 171 MB free!!)
care,
Sony.
have you tried using the stock app manager and killing the apps there? i just checked my phone and i have the same apps under the running tab using the stock manager, i think email and messaging are always running since you have push features on them, in terms of the others im not sure. whats so bad about email and messaging running anyways? im sure you use them often enough to not want to have to open and close them right?
Hey, you posted the same question over at Pocketables forum.
As stated earlier, 2.2 is really good at managing back ground tasks.
I can tell you if you use a task killer and you have a problem with an APP, which currently you do not, the programmer for the app probably will not help you till you remove the APP killer program.
What you might try to do is run though your menus and see what you have selected to run, such as locations and sync services and disable what you can. Also if you do not want some thing running, you may want to just uninstall it. I do understand that you want some programs but you only want them to run when you ask, not sure how to tell you to handle that.
But, are you seeing any difference when you have the background tasks disabled. Try to find the APK for the programs and rename them just to see if you have any issues.

[HELP] Trying to find a solution to apps running in background. Any way to stop them?

First of all, I KNOW THIS HAS BEEN BROUGHT UP BILLIONS OF TIMES, SO BEFORE YOU REPLY WITH "Search the forums" READ THIS.
I have been looking for WEEKS trying to find an answer to this,and no answer given on any forums are what I am looking for.
I have an android phone (sidekick 4g) and there are apps that run in the background when not necessary. Now I know some stuff need to be aways running for the phone to function. But I also know that apps like Facebook, Market, Gmail, T-mobile's Media Store, MyYearBook, Maps, Aptoide, etc don't. When I force close them, they just start up a few seconds later. I've tried task killers and got the same result. I've read the "Why you shouldn't use a task killer" articles but everyone keeps saying different things about it so I'm confused.
Like many others, I want my battery to last at least half way through the day. The above mentioned apps (and some others) DRAIN THE BATTERY WHEN RUNNING IN THE BACKGROUND WHEN I DON'T WANT THEM TO.
Please does anyone know of a way to fix this?
My phone is rooted, if that matters.
Also, "freezing" the apps don't help cause then I can't use them when I actually want to.
Thank you very much in advance anyone who can help me out!

Applications running, doesn't mean cpu cycles are being used. Sitting in memory is no different then a song sitting on your sdcard. Your issue with the battery has to do with processes using cpu cycles. If you have applications that update, force updates manually.
Just having apps in memory isn't your issue.
Use the features built into the os, find out what apps are causing the problem. Look at the settings. If you have looked at your settings, then you have one of three choices. Open bugreports with the application developers, don't install the apps causing problems, or upgrade your phone.

Thank you that makes sense.
I would think those apps would use battery because it pushes notifications for the app (like new messages and stuff). Does that not use battery?

It does use battery because to process the notification it needs to use the cpu. If you force applications to update manually. Your batter would be better. Check into battery saving tuts. All that information has already been discussed plenty. Won't change in this scenario either.
The more apps you have updating information the more data and notifications are being processed.

Also, I have another problem, if you know anything about this kinda stuff. The Facebook app icon just (like 10 minutes ago) disappeared from my home screen, and it's not in the app drawer either. I uninstalled and reinstalled and still having the problem. I can only open it by manually searching "facebook" in the google search widget and that's when it gives me the option to open the app. It's really bizzare and I have no idea what's going on.

Sounds like a issue with the rom or launcher. Try installing another launcher from the market and see if the application is installed. If its there with another launcher then its your stock launcher, if its not then its the rom.

[Q] Killed app keeps reappearing

Hi folks,
I have a peculiar problem. I'm using Tasker to kill some apps. One of the apps has a persistent notification icon and it refuses to be killed (even with root). The notification icon is gone for a second but will always come right back. Using pstree I tried to find out if there was a watchdog process keeping the app alive, but I found none. Also it is not hooked to any events according to Autorun manager. A force close under "app management" always works.
What is going on?
This seems like an answer that has been asked before. So off course I have searched. I found similar questions (examples: http://forum.xda-developers.com/showthread.php?t=1854858 http://forum.xda-developers.com/showthread.php?t=2040841 ) but no answers.
Who can help me? I'm really at a dead-end.
what app is it? Some apps (especially system apps) can't be closed, and if does gets killed, OS programs it to restart almost immediately after it's been killed.

This is actually Android-by-design. Apps are supposed to be killed from time to time to conserve resources (e.g. memory), and also restarted transparently to the user. This is handled by the ActivityManager. You can view it as Android swappes app's instead of swapping memory. This to improve the real time performance of the device. When someone calls you, you don't want to wait half a minute for the phone to swap out Angry Birds before it can load the Phone app ...
Hence, killing app's will most often only give very short term effect.

[Q] update.appfansworld.com in Chrome browser

I am getting an annoying spam/popup whatever in my Chrome browser. It's very deceiving and I've tried restarting Chrome, the phone, clearing cache but it still pops up all the time. It's from "update.appfansworld.com" and gives me an initial message about memory being low or something. Attached is a screenshot. Anyone know how I can get rid of this?
If this is an app.
Go to settings > application manager
Find the system ui upgrade app and uninstall it.
Is it a popup? If so try an ad blocker. Or figure out what site's giving you this junk.
If your user agent string is reporting as android (in Chrome it is) they can tailor ads to look like "updates".
If you get the "memory slowed" message hit cancel or the back button.

Fixed this problem on my phone by going into the App Info for the Chrome App and Deleting All Data. Just had to resign into Google, and it has not come back so far.
Update.... Went one week with no pop up. Got one again from app fans world. Com again last night. Not the UI one though. This one said my browser crashed, which it hadn't. Spent several hours trying to get it to repeat, but it never did, nor did it today. Just as a final check, I ran Malwarebytes, and found only one instance of malware on my phone, but not thinking it was actually malware. It was the root uninstaller file for Smart Ram Booster Pro. I uninstalled the app anyway as I don't really use it. Will give an update on this in a week or so. Looking online, this is becoming a widespread issue.

Yeah I tried deleting data in the chrome browser but that didn't prevent it from coming back. I'll look forward to a solution if you find one.
After clearing the data under app info it stopped for a week for me. It was popping up every other page almost before that. Now, it popped up again just once, and I did a couple weeks worth of browsing in a couple hours after it did, just to see if I could get the pop up again to inspect it better, but it just won't come up again. I don't know if it is gone, or will pop up again sometime later. Weird.
I have been following a guy on the Verizon forum dealing with this. He was going to run his phone in safe mode, and try activating one 3rd party app at a time, using Terminal to see if he could find an app that was causing this. That didn't work though as while in safe mode with no 3rd party apps activated, it still happened. He is now going to reset his phone, reinstalling apps one at a time to see if he can find an app causing it. This will take more than a week though, as he will take time to test chrome for awhile after each app is installed. One thing to note is that the app.fansworld.com site was only created 12.18.14. It could be any app you installed slightly before to any time after that date, or even any update installed then. I am almost thinking it is something to do with Chrome, as I don't install anything except from the Playstore, and only a thing or two that I can remember during that time frame. I am going to both uninstalled all chrome updates, and try a different browser, to see if it still happens. If it does, I am going to factory reset my phone, and see if I can fix it.

I assumed it was a chrome thing since that's where it always pops up for me. I guess I could try another browser...
I did click on the page (clicking cancel or update does the same thing) as I figured I will be reseting my phone anyway. No matter how many times I click on it, all it does is redirect me to the Dolphin Browser page on the playstore. This makes me really suspicious because the developers of Dolphin Browser wouldn't ruin their extremely good reputation by doing this. I think the redirect is a cover for something else. Maybe a keystroke logger, or something just as malicious. Rolling back Chrome didn't get rid of the page that pops up. No popping up with new browser so far, went with Maxthon, but it is early. Really starting to think a complete wipe and reset is necessary. After all, the pop up is only what we are seeing, what else might be going on we can't.
Quick question... Have you downloaded any (.flv or.m2v specifically) video files during the time frame? Read a recent article about hackers using them to exploit vulnerabilities. Right now it is suggested not to download those 2 file types at all.
Factory reset my phone, which was a small hassle, but it has fixed it, and the other small bugs and slow downs that appeared at the same time. Back up your files... Pics and such you want to keep, and reset. Your phone should automatically re-install all your apps, although you will have to redo some of your settings. After you save your files to wherever you want, I saved them to my pc, just go to settings.. Then back up and restore.... And select factory reset or reset phone, however it is listed. Your phone will then be like brand new, and you will only have to re-set up a few things as most things will reinstall by themselves with their previous settings. Like I said, a small hassle, but it fixes the problem, and you again know your phone and data is secure.
It started doing it again today. Reset didn't work. Talked to the guy on verizon forum, and he is going through all files to locate it's origin. Will just have to wait until he is done. FYI--It started happening in other browsers too.

Is an app killer what I need?

There are at least two apps (that I've noticed) which seem to act strange when I run them again after running them once. The strangeness vanishes if I go into recent apps, swipe the app away, then run it from scratch. I get annoyed at having to do this frequently. Would one of the many background app killers out there achieve the same effect automatically without me having to swipe the app away? Any recommendation for a killer I can restrict to just certain apps? Is there any setting on the s21 to say "never cache this app in memory"?

No offense but it sounds like the issue is with the apps and using an app killer to autokill the app is nothing more than band aid. The app killer would be yet another service that will run in the background using up your resources. I think you would be better off contacting the developer and see if they will allow you to submit logcats so they can fix the issue(s). This would help you and potentially help others as well. I would also see if there any alternative apps that can do the same thing.

The most irritating one is the Chase mobile app. Attempting to contact the "developer" gets me chase customer service who wants to help me reinstall the app. Pleas to forward my mail to the actual developer are met with total incomprehension .
Okay. We might try going deeper here. Did the problem always exist or did it start randomly? If each one was working fine at one point it could be an update from the developer broke Apps. Did it start after an update to the app or the phone Rom?
Did you customize and/or disable the os or rom baked services/apps?
How long have you had the phone? Did you upgrade from android 11 to 12 and do a factory reset? Just some questions to see if there might be other root causes.
Everything is stock with all system updates from samsung applied. I'm pretty sure it started after an app update. The chase app insists "You are not connected to a network", but since I was just on chrome looking at web pages, that seems unlikely. It acts more like the app doesn't clean up everything correctly on exit, then if android keeps it around in memory, it has trash in uninitialized variables when starting back up again. I've gotten pretty good about swiping it away from recent apps, so even if they fix the bug someday, I'll probably keep doing it from reflex .
Have you looked at recent comments for the app on the play store? Are there similar complaints that started around a certain time? That would be a definitive indicator if it was an update issue.
I commented about it and since then 15 people have found my review helpful, so maybe that means they have the same problem.

Yeah...that is unfortunate. It looks like you may have to wait on the company and developer to fix it.
