[Q] SGS3 with Android 4.1.2 "sort of" freezes randomly - Android Q&A, Help & Troubleshooting

Hi,
Since a week or so now, my Samsung Galaxy S3 with a rooted Android 4.1.2 "sort of" freezes randomly. And with "sort of" I mean that animations and such (can) keep running, it just doesn't respond to any kind of imput anymore. I had it freeze on a youtube video, but the video kept playing till it was done (but it didn't continue like it would afterwards, so the process definitely froze too).
I have no clue what sets it off. I've had it freeze while using navigation, while browsing, while typing, while taking a photo, while turning the screen off (it will just stay on forever), anything. Sometimes it freezes 5 times in 5 minutes, sometimes it freezes only once a day. In all cases, the only way to get it back to life is by taking the battery out and putting it back. Waiting doesn't do anything.
I thought it might be a memory card problem, but I unmounted the card and got the problem again just now.
I figured I'd download an app that writes logfiles to see what is happening, but all those programs don't work anymore with the current version, due to that the programs only have access to their own logs now.
Does anyone have a clue to what might cause this, or a way to troubleshoot further and try and find the solution?
Thanks!

gps crashes phone, problems logging crash

Thank you for reading. I feel really stuck and though I've tried cannot solve this on my own.
The Problem:
When my phone crashes, the logcat apps that are happily recording the events get force closed along with it, and the buffer is lost forever. I seemingly have no way of recording the actual crash event so that I can research the problem.
Possible Solutions, Unfounded:
So I guess what I need is a logcat app that writes the events to file as it's reading (none seem to offer this, only saves manually) or a way to read the internal log after the crash occurs.
Crash Description:
When it crashes, I get a few short successive vibrations, then a lot of lag between a few seconds to a minute, then (if I'm lucky) the screen goes black for a few seconds and then a sort of an instant reboot occurs where I am at the home screen and all the widgets/icons are loading again and all the programs running a moment ago are not open, and any programs normally loading on a startup will start. It always will say the Sim Card has been removed and I must reboot. I lose contacts but not network. Sometimes the phone just freezes without going black and the fast reboot occurs after some minutes or not at all.
Background on what causes the Crash:
As you know, the GPS on the Fascinate and other Galaxy S models have serious issues with accuracy. I have tweaked the internal settings (*#*#3214789650#*#*) myself, without modifying system files (I dont think I ended up going that far) in order to produce better results. I did this months ago and havent changed it since.
The tweaks did not perfect it, so for some apps where accuracy is crucial I temporarily use an app called FakeGPS, which allows me to manually set my location while the app is running. It worked fine. After I updated about 12 apps at once, FakeGPS included, now whenever I run that application the phone crashes as described above.
At first I thought it was just the new version of the App, so I tried a different one that did the same thing. But it also crashes in the same way. I reinstalled both, still crashes.
I am using firmware 2.2. My phone is rooted. I'd be happy to answer any questions.
Really appreciate even just a point in the right direction.. I wouldnt be afraid to poke around the filesystem if need be.
Thank you!

[Q] Galaxy S3 lockscreen hang and also unresponsive blackscreen

Hey guys,
I know there has been a couple of posts like this that I have found through searching but none have actually found a solution, so instead of resurrecting a old thread I thought I would start a new one.
Basically I am having some issues with my new pebble blue (yey) S3 . I have found that sometimes when the phone is sleeping when I press the power button to bring it out of sleep the lock screen begins to hang. This is followed by a number of different things, the screen either glitches for a bit and then begins to work or it stays locked and needs a battery pull. As well as this I've found that randomly either when charging or not and the phone is sleeping it simply becomes unresponsive, staying on a black screen and needing a battery pull to fix (this has only occured a few times, the hanging lock screen occurs quite often).
I have done some searching and found little in the way of a solution or what the problem is, however I have found that when the lock screen hangs -if it begins to work again after glitching out the 'WIFI connected to ****' appears at the bottom of the screen. Anyway if anyone has any ideas or also recieves this problem I would really appreciate some help as it's driving me crazy and I'm unsure if it is a common S3 bug or a faulty handset, in which case I have limited time to RMA.
Cheers in advance
Hmm, sounds like a faulty phone to me. Try taking it back to get it exchanged for onother one. S3 was built to fly not crawl.
You'll want to go through a process of elimination to figure out when might be causing it.
Something you can try and test with (one at a time)
-turn on airplane mode
-turn off live wallpaper
-shut down all running tasks
-change your lock screen security method
-limit the number of widgets running on all the screens
-reduce the number of active screens
Probably other things you can try to pull out of the equation, but thats a good start
After looking up dial-a-phones returns policy it would seem that I have 28 days to return if the handset is faulty, so this atleast gives me some breathing room to try out any suggestions for fixes. I will begin to eliminate each of the suggested items above however as the lock screen problem is intermittent it make take a day so actually see if it has had an effect, which is annoying at the least.
On another note a numberupted of people are stating high battery life on their devices however mine doesn't seem to be as good and I do have power saving on as well as nfc etc. turned off. This makes me believe my handset could have a fault, but tbf I haven't allowed for a discharge to 5% and the recharging to 100% which I heare allows for optimisation of the battery.
EDIT**** I have changed the lock screen previously and found it had no effect on the problem and I do not have a live wallpaper in use.
Phone Freezing after reboot and auto wifi signal found on.
Same here, been happening the last few days after I installed Avast. Also, turning off and on the auto on wifi seemed to replicate the problem.
The phone will boot to the lock screen and freeze a bit, and sometimes the news ticker freezes, and then after unlocked, I try to turn off wifi signal has been found on the notification dropdown and then tries to auto connect to wifi, the phone will freeze up if I dont turn it off in time.
Once the auto wifi connect is off and reboots, then the phone will keep glitching up until it catches up processing alot of processes it was trying to do for about 1/2 hr. Also, if phone freezes up for too long, like after trying too many time of unlocking the screen while freezing up, the phone gets stuck at the lock screen and the phone almost overheated, in an area right below the battery. I had to pull the battery out to cool it off.
It seems to be a glitch in the auto wifi, especially if alot of resources are being used. Once Avast was on my phone about 1.5GB RAM is being used sometimes and since has really slowed the phone down. Going uninstall alot of apps.

Same problem.
No problem if Wifi is switched off prior to sleep.
No problem if Wifi connection is still available.
Problem to lockscreen if Wifi connection is broken (move away from connected router).
Any suggestion?

Exactly the same here. Driving me crazy. I did root the phone using the Samsung Galaxy S3 Toolkit. I don't know if the problem also exists on non rooted devices.
S3 black screen after unlocking
Has there anyone experience S3's screen went on black? I have pebble blue S3 - GT-I9300. Cases when unlocking, answering an incoming call or attempting to turn off an
alarm? Mine happens when after unlocking the screen then it goes black and screen becomes unresponsive. It happens intermittently and even after 3 times of
reprogramming. I am now going to have it replaced. I am having a lot of troubles -- it exits on its own when im reading or composing an SMS; files were deleted after
restarting the unit, and an app opens up even not touching the scree. This is expensive and I am paying a lot just to experience this king of inconvenience.

I also rooted my S3 a few days ago (with the S3 toolkit), and have had lots of problems with unresponsive lockscreens (I use PIN, because of exchange connection). It takes a few seconds or maybe up to as long a minute before I'm able to punch in the PIN-numbers. Before this the screen lights up but does not respond to input.
But the WiFi-connection issue might be what is the triggering factor, because after a boot it wotks just fine for several hours, if I'm not moving out of my current WiFi zone. First I thought it was either Secure Settings or Tasker that made my device lock up in this matter, but now as they are both uninstalled, the problem still occurs.
Are you running some kind of custom rom, or just the latest stock ROM, but rooted?

Just the latest stock ROM but rooted. I've found out that turning off the wifi power safe mode fixes the problem for me. To do this:
- In the dailer enter *#0011#
- Press the menu key
- Select wifi
- Press the on/off button.
The wifi power safe mode will however be turned on during boot. So rebooting will set it back on.
*#0011# seems does the trick. But is annoying had to do this every time after power off (change battery, change Sim, flying).... Anyway to keep the setting?
I am also on stock Rom and rooted. Interested to know any non-rooted phone got this problem?
BTW. I found a quick (at least quicker than pull the battery) way to get out of the forzen lock screen (sometimes forgot to do the 0011 trick): press the power button (screen will Dim instead of OFF), then hold the home button for few seconds, as soon as you see the "menu" and "back" button lit up, the lock is un-freeze...
A permanent solution is appreciated for such an advance phone....

Not that I know of.
Problem solved. For me anyway. Hope works for all of you having the same trouble.
My trouble begin with recent upgrade to LH3. My S3 was rooted by S3 toolkit v2.0. CWM installed was v4 something.
I un-rooted the phone. Uninstalled S3 toolkit v2.0. Re-installed the S3 Toolkit v5.0. Rooted the phone again (CWM become v6....).
I do not know it was CWM version caused the trouble or not. But my S3 is ok now.
I got it on my non-rooted phone, any additional solutions/suggestions? or service?
I found solution for problem . And my phone is working well. I downloaded rom file android 4.1.2 and flash my phone
JB 4.1.1 caused these WiFi issues on my phone

Exact opposite for me...never had the problem then since loading stock JB 4.1.1 with root I get lockups or freezes whenever WiFi is turned off or I leave my router's range. As soon as I disconnect from WiFi the whole phone freezes.
The *#0010# also locks up the phone when I turn off the WiFi power saving feature.
None of this happened before JB...and I replaced my phone with week via warranty due to this and the new phone does the exact same thing as soon as I upgraded to JB with root.
Any ideas?
Black screen / random reboot solution
Hi All,
I've had the black screen / random reboot issue for a few days. The only way to restore functionality on black screen lockup was to remove the battery.
I tried changing to Chrome browser and stopping the stock browser as suggested in some threads but it kept crashing.
I searched everywhere and most threads suggest a dodgy motherboard.
For me the issue was related to either a single PDF download via the stock browser or the fact I had quite alot of saved PDF files on my phone (S3 Stock firmware I9300XXELLA)
After deleting all the files listed in Internet downloads (look for Downloads with a green arrow Icon in apps) my trusty S3 has returned to normal. No black screen lockups, no hanging, runs like a dream!
I appreciate this may not solve everyones black sceeen issues but I haven't found any other thread with this solution. Hope it works for you.
Thanks,
Giz.

Thanks for the tip...
Was this happening on JB for you? You mention stock firmware (not familiar with I9300)...so I am guessing it was ICS.
For me the issues are with JB and I had no files at all in the Downloads folder after a certain point when I wiped / formatted the SDCard...so I do not think my lockups were related to PDFs. But I did (and still do) have a ton of music and a lot of movies on the External MicroSD Card....and quite a few custom notification and ringtone MP3s on the Internal SDCard. Next time I load JB I will run it a few days with none of this media loaded....

This is on JB 4.1.2, Phone had been updated to 4.1.2 for about a month. The issues started after a pdf download. Once all pdf's were deleted the handset works perfectly.

[Q] S II 'soft' reboot

Apologies in advance for the potentially vague description, but I also cannot find a solution elsewhere on the forum.
Earlier today, I was watching a YouTube video and then I locked my phone and left it to charge whilst I went downstairs (as I often do). When I returned roughly an hour later, I found the screen on, which I only ever do if I've left Draw Something open, or some similar app - but it was on the lock screen.
(none of that is necessarily important, I just wanted to clear up the "what did you do to make it start rebooting" question)
Anyway, after unlocking the phone, the screen went to black and the phone restarted.
However, it wasn't a "real" reboot, because the boot screen didn't come up, etc. It's just like just the UI is restarted. I can usually use the phone for about 30 seconds at a time. This seems extended when I have flight mode on, and is even longer still when I have the phone locked.
I've uninstalled some potentially-offending apps, removed the SD card, cleared some apps' data, but to no avail.
I'm using default 4.0.4 from Samsung. The only issues I'd had with it until now were that some apps crashed occasionally, but I attributed that mainly to the apps themselves.
The most annoying thing for me is that is seems like it's an issue that can be fixed quite simply, without having to uninstall every app or factory reset the phone.
Anyone have any other ideas as to what I could do? Thanks!

[Q] Galaxy S3 I9300 - started freezing randomly but screen plays animation

Hey guys. My S3 started freezing randomly a few days ago. What happens is that I will be playing with it and then it will literary become unresponsive along with the hardware buttons except the power button. The weird thing is that the animation on the screen is still active: say I was writing a text and the little blinking bar keeps blinking as if nothing is wrong but the phone is simply unresponsive.
I did a factory reset and it is still happening.
Anyone have any idea what the heck is happening? Is it hardware or software related?
Have a read of the freezing thread in general forum, sounds like the operating system is dealing with bad memory blocks.
Well, same thing happens to me, i looked up on that tread about bad memory blocks: well i even tested the memory and works fine, no bad memory sectors, my hardware power button responds to restart (no need to pull out battery). When it does freeze it doesn't unfreeze at all after some time ( i once let it unfreeze for entire night on charger and it stood on the same screen after 8+ hours). I even reinstalled a different software (JB 4.1.3 Darky edition) and it freezes very rarely now but when it does, it's still same kind of freeze. When it freezes it freezes mostly on Twitter app but sometimes random app. I don't know now is it really a faulty memory or just software bugs... btw dummy file didn't freeze my phone (to be clear) after i reinstalled the software, but did it before on old one
Help! Galaxy's freezing!
Hello,
I have exactly the same problem, when phone freezes nothing works except power button, when pressing it about 10 seconds, the phone reboots. I have exactly the same model (GT-I9300), but Lithuanian. The freezing lasts from 10 minutes to an infinite time. All the freezing started about three weeks ago, when google play started updating iron man game. I tried dummy file geterator, the phone hasnt freezed at all, but the phone freezes randomly when opening internet, other apps or just anytime, even when phone is on stand by. I tried flashing DarkyRom 4.1.2 XXEMB1, but the phone started freezing even more, then i recovered from the Nandroid backup, and the phone is now freezing not so frequently, about 1 freeze in 2-3 days, but it still freezes, and i also have a strange "Process com.google.process.gapps has stopped working" problem. I tried every solution to this problem, but none of them works. Also, i think it is somehow connected to the freezes, because after those messages phone freezes sometimes. I dont know how to solve these super annoying problems, because i tried nearly everything, and nothing works. I think this might be a hardware issue, and that i should buy a new phone. If you know somehing, help me!

Lag spikes every 3 seconds

Hello guys, I have a Samsung Galaxy A10 and since today that I'm having an issue with it. Every 3 seconds there's a lag spike in the operating system only. In apps its completely normal no lags at all. For example if I continually flick the notification bar up and down i get a lag spike every 3 seconds every time. It happens the same with the navigation buttons on the bottom, keyboard, basically anything related to the os. But in apps I dont have this issue. I think it all started when I plugged in the charger and i got a warning that was water on it, but there wasnt any water that warning sometimes pops up when the cable slips a little bit and gets halfway attached. I restarted the phone multiple times, it seems fine on boot but quickly goes to the same problem. The phone is not rooted, it's original firmware and all. Can anyone help me out here?
@crazyon3
Try this
Uninstall apps which haven't used in last 30 days. No need to worry, you can always install back when required.
Delete all images and videos of WhatsApp and similar which are just forwards. It will be a big chunk usually.
Move all personal pics and videos to cloud (Google Drive). Enable auto backup. Delete device copies for > 1 week old files.
Run SDmaid app. Uninstall it after that.
