Are you Running a Custom ROM?
If yes you should go into your ROM's thread .
If you are running stock Android , the problem comes from the OEM , you should search for this issue on internet to find someone else who faced this bug and try to know if there's a fix.
On my side , I can't do much because I don't own your device and I never heard about this before
I hope you'll find the answer on the internet

[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] Galaxy S3 getting stuck in sleep mode / Locked.

I'm currently having this issue and it's really frustrating, I had it first on the Galaxy S3 with 4.2.1 stock rom, I don't know if it might be an app that might be causing this, basically when i lock the phone the screen turns off but then when i press the power button or the home button to turn on the screen it does not do anything, I know the phone is still on because sometimes if i get a text message i can see the blue led blinking and it will continue to blink even when it's frozen.
The only way to bring it back is by holding the power and home button together in order to reset it.
I tried factory reset and it would not work, I flashed the phone with a custom rom for Paranoid Android 4.3 and it worked great for about a week, no issues at all, but then it started freezing when locked again. I hate this and i'm thinking it might be a hardware issue since I've tried different software versions.

Even worst, if i'm listening to music and i lock the phone or if the screen times out and locks when i try to unlock it i can see it's stuck but the music is still playing....
Also, if the phone is stuck and i try to call it, it will not ring not turn the screen on, it's not like the problem is just the physical buttons, i don't know what to do since the phone is out of warranty, I have never dropped the phone and there is no damage on it, it have never over heat either so i don't know what can i do.....
Any suggestions or help would be really appreciated.

But it's really strange, It is a hardware issue and it should affect all the time, not randomly i would think... I don't know if the problem is with the processor or the buttons, i don't know how to determine that..

The first week with Paranoid Android 4.3 it worked greatm even faster than the stock rom and I also liked it because it is android 4.3, the issue started one week after, and i'm thinking that during the first week i did not install all the apps i use, once i installed all the apps it started happening.
The first time i had the issue was right after the facebook messenger app was updated, i tried uninstalling it and the issue was still happening, if i check the running apps and i can see several of my apps running in the background such as Facebook messenger, Viber, Skype, Avast (6 services) Applock, GO weather EX, whatsapp, Facebook.
Maybe i'm just reluctant to think that this is a hardware issue, cause there is no way for me to get some logs or a hardware report that may show any crashes or anything.. I like this phone, it have everything i need and i refuse to think that it's a piece of crab but i've had nothing but troubles with it since day 1...
I dont think it is SW problem because even flashing multi package stock firmware doesn't fix the issue.I tried replacing lcd and display driver but still remain unsolved.
Edit:I think there is a defective sensor chip which I don't have a unit to test already.
hello, i have same issue, and stil stuck with it, anyone can help me?

Galaxy SIIX SGH-T989D crashing issues

Hi,
I'm looking for some general advice and troubleshooting for my phone's issues. My phone started crashing very often, sometimes at complete random, as well as when I was using it fairly heavily (any app that froze my phone for a second before loading before the crashing would now crash my phone). Sometimes it would reboot fine, other times it would bootloop once or twice before reloading fine. I previously tried doing a factory reset, removing my external microSD card, and updating everything via Kies and nothing worked.
I got bored and rooted my phone, did a full wipe, and flashed the latest Infamous update. The problem was still there but it wouldn't crash as often while using it because my phone could handle higher app activity but it's still there. Oddly enough, after flashing Infamous, it often fails to reboot and so I have to do a battery pull before turning it back on, otherwise it won't even vibrate after holding the power button.
I'm just wondering if you guys have any idea what the issue could be. Is it likely still something I can fix? Is this potentially a battery issue or is it a hardware issue?
Thanks so much!

System lag after 24hrs of use

I don't know if it's just happening to me, but after upgrading to Android 10 the system really got faster, but after an average of 24 hours of use and especially after loading it 100% again, the whole system and apps seem like start to lock up, you can see a huge difference in the speed at which I use apps and when opening apps, apps get less fluid in the passage of news feeds, sometimes the phone gets to lock up, but you just have to restart phone so that it goes back to fast again.
Is anyone with the same problem?
On Android 9 I don't remember this happening
In short: I need to restart the phone every time I charge it so that it doesn't get stuck
Yes it's happening the same way as you described after upgrading to Android 10.
It seems like there is a RAM memory management OS bug
Yes you need to restart the phone then only it gets to normal state.otherwise keeps lagging.
If you just remove the app from background,I saw No memory is released from RAM(With CPU-Z).must be memory management issue
Same problem
Are you guys on global or EU? I don't have this problem. And I haven't done a factory reset since updating.
Using latest stock OTA for global, btw.
I am on EU version for me uninstalling chrome to factory fixed this issue I am running for 60h and no slow downs
Old post but can confirm disabling built in Chrome solved the problem for now.

Might be a specific app that is causing problems. When the problem happens again just reboot into safemode by long tapping on the restart button or power button. And then see if the problem still persists.
