Sprint SGS3 Freezes,Crashes,Reboots, deletes contacts? - Sprint Samsung Galaxy S III

Hey, I'm having serious issues with my GS3 lately, I got it a few months ago from Sprint's suckish replacement plan.
The problems started a few weeks after I got the device, so I can't send it back or else they'll charge me, I've tried flashing different ROMs and restoring to stock several times and nothing seems to work.
The problems are: The phone randomly shuts down(crashes?) and I have to hold the power button to get it to turn off and I just guess after a few seconds, let go and hold the power button down again to turn it back on, the lock screen freezes, I have to turn the screen on and off a few times before it responds, the phone randomly reboots, it just turns off and back on without any type of animation, it just simply does it, the phone also, in some reboots it optimizes apps as if I had just updated and sometimes it deletes my contacts and text messages.
I have no idea what's going on, I've been trying to bear this problem but I just can't take it anymore! >3<.
I've tried the "Ultimate freeze/crash" thread to no avail.

....
I just tried flashing the new MOAR Rom and it still keeps doing it, my phone runs fine for a few hours before one of the things listed above happens.

Bump...somone please help ;-;

[Q] Lock Button Issues

Recently my Captivate glide has been having many issues. Originally it started when my phone would just randomly turn off for no reason, I attributed this to overheating and figured maybe it was a normal thing. Eventually it got to the point where the battery would hold no charge and I could not power on the phone. I replaced the battery after noticing that it was swollen and this seemingly fixed the issue. Though after a week or so I noticed there were still a few problems with it in regards to it going off randomly and coming back on but nothing major. Last week though I was at the gym and it dropped from my pocket I picked it up, put it back on but a few seconds later it turned off again. I just figured it needed to charge. I tried later to turn it back on that's when I noticed that the phone would keep randomly going on and off constantly and the lock button no longer worked when it was on so the only way to unlock it was to slide it out. I figured it was just a matter of replacing the button but it got worst and now the phone wont stay on, It comes on for a second, boots up then turns off, the battery has 0% at all times and even if it's on the charger and shows the charging icon, it won't stay on. For the few minutes that it is on for, the lock function spasms and the phone keeps locking and unlocking itself, eventually showing the lock button menu then finally going off and coming back on. I gave the phone to my friend to check out as he fixes a lot of phone, he took it apart but there was no damage to the button or anything holding it down that would cause the problem, he used a tester to test it and found that it was working fine. He thinks it might just be a software issue and suggested I reinstall the OS. Does anyone have any insight as to what might be the problem and a solution?
TL;DR Lock button on phone acts as if it's constantly being pressed and won't remain on for longer than a few minutes and even when it is on, just keeps locking and unlocking itself before shutting off.

[q] screen is glitchy after dropping!

Two days ago, my T-Mobile Samsung Galaxy S3 dropped out of my coat pocket as i was running for the bus. I picked it up and saw the screen was cracked along the top left and bottom left hand side. Everything was working for the past two days and i figured i'll just wait till Christmas to get a new phone. This morning i took my phone off the charger and turned it on. The Samsung logo flashed, and then the boot animation for Slimrom (the custom rom i'm currently running on) flashed for about a second but then the screen went black. I did a battery pull but the weird thing is whenever i put my battery back in, even without touching the power button, it boots up by itself but then the screen goes black again. I can access TWRP and download mode but they both go black after a few seconds as well. I was able to successfully turn on my phone and have it fully function for about 15 minutes after putting it back on the charger, but it quickly blacked out again. It also keeps randomly booting up by itself which is weird. Im guessing this is a problem with the screen itself, but could it be a software issue because the device keeps booting up by itself? If it is the screen, will i have to buy a new one or is it not worth it? I've also tried using a different battery and i have the same issue so it can't be that. Any help is appreciated!
Sounds like an issue with the power button, it probably got stuck somehow either when you dropped it, or after you dropped it. Do a simple search for power button and you will find ways to fix it!
Holy crap i didn't even think of that! It makes total sense since every time i even tap my power button, even for just a second, it turns on. I've read around that clearing the cache or a factory reset could work. Is this true?
Unlikely, unless it's a software issue but it's always a possibility. Slam the phone against something to try to get the power button back into place, or open it up and try to see if you can fix it yourself, or replace it
The problem seems to be gone. I haven't had any issues for two days now. All i did was press the power button really hard multiple times. Thanks for you help man!

LG G3 unresponsive/extremely slow

Hello there. I have to write this again becuase the last topic I wrote didnt get posted...
I have a big problem with my G3 and I have tried everything I could but nothing helped so I hope you can help me.
First of all my phone is only stock. I didnt try rooting it or installing custom roms on it.
Heres the whole story of what happened:
A week ago my phone started to act strangely. When I tried turning the wifi off it restarted or froze for a bit and then went on normaly as if nothing happened. I didnt even have to input my pin. Then one day I got home and the phone simply started reseting itself constantly. Always loaded up to the pin screen but I didnt even have time to input the pin and it reset it self again. This went on for like 15 reset before I lost patience and pulled the battery which didnt help at all since after being turned back on it went back to the reseting. I found online that it was probably a battery problem but I was impatient (shipping to my country is over 2 weeks and buying a battery in stores here costs twice the normal price of a genuine battery but only for a "fake" battery) so I factory reseted it via power button+volume down. After that it worked normally but I lost all my data.
The day after this I spilled ice tea on the phone. I opened it, cleaned it and let it dry out. Turned it on after an hour of drying and it worked but after maybe 2 hours it began freezing. When I tapped on the screen it didnt react, when I pressed the power button it took more then 10 seconds to react to it. It turned on, didnt react to touch and then in mere seconds it went dark and then turned off. I couldnt even unlock the screen. Tried pulling the battery but then it wouldnt even turn on. It stayed on the LG logo. I left it on the logo and on the charger and after an hour or so it turned on and worked normally so I took it apart and cleaned it once more even under the screws and such and it worked after that. Until today.
The freezing problem returned. I was playing a game on it and chatting via messenger when the phone stopped reacting. I had signal, wifi, I got new notifications and basically everything on it worked but the screen didnt react to touch and when pressing the power button it took over 10 seconds to light up the screen, then it went darker and then it shut down. Couldnt do anything. After I pulled the battery it would get stuck in a boot loop for maybe 10-15 minutes and then load but the phone couldnt be used. Just as before the screen turned on with a delay but no reaction to touch whatsoever.
I tried factory reset, downgrading to a lower android version (from 6 to 4) with LGUP and lg flash tool, and I bought a new battery. Nothing worked. I managed to get it to android 4 but that didnt help either. I though it was a problem with 6 because the problem started after the update, before that I didnt have a single problem with my phone.
Now its in a state where it doesnt work. The phone is running, apps are upgrading after the factory reset and all that but I cant do anything with it. Once in a while it will work normally as if nothing but that is rare.
Could you please help ? I love this phone and I dont want to have to sell it for spare parts.
EDIT: I left the phone running to see what would happen an after several hours an error message appeared saying "Process system isnt responding". After pressing ok it worked fine. How can I fix this. I googled it but all I found was a problem with sd card (none is inside), with battery (I have a new one) and with rooting (mines not rooted).

D850 Screen unresponsive randomly HELP!....please?

Hello everyone, I just recently got a G3 and it was working fine for the 1st 2 days, no issues. I was sending a text to a friend earlier today and after it sent, it completely froze. After doing a soft reset it took forever to boot up. Once it booted up, it seemed to be fine. about an hour of operation, the screen looked as if it was freezing because it wasn't recognizing any of my touches. i decide to flip the phone sideways to see if it was actually frozen but it changed to landscape just fine. Sometimes it comes back to life then goes off again shortly after, and other times, i have to soft reset. I've tried the following to no avail.
Took the phone apart and cleaned both connectors.
Re-flashing the rom.
Trying 4 other roms.
Returned to lollipop stock.
I can't figure this out for the life to me and worked my ass of to be able to buy this phone. Any help would be appreciated as I can't afford to spend any more money on it!
I also have this issue, it's been ongoing for a few weeks. There will be short periods where it can work just fine, then it just freezes up and does not register any inputs. The content on the screen continues to run as if nothing happened (videos and games keep playing). Turning the screen off, waiting a couple minutes, then turning it on can sometimes give me another minute of use until it freezes up again. Also of note, when the screen is unresponsive and I press the power, it will dim to very low levels for a few seconds before going fully black. When the screen is being responsive and I press the power, it goes straight to black, as is normal and expected. From my testing, I've concluded:
1. This issue is not app dependent. It can occur at any time, and is not caused by alarms or overlays, such as blue light filters.
2. The issue is not from the specific battery I use. I've switched out between multiple batteries and used different chargers, none seem to affect the frequency of freezes.
3. Temperature may have something to do with this. When waking the phone after it's been sitting out in the cold, there seems to be a higher likelihood that it will be unresponsive. This is not always the case, which makes concluding that the issue is hardware related difficult, but some correlation seems to exist.
4. This issue started occurring shortly before I began having the popular "SIM Card Removed" issue, which I've yet to resolve (though can sometimes get the SIM card to work)
I am running stock 6.0 D85030p AT&T. I will post here again if I figure something out, but I have been trying for weeks without much success.

I think my phone is on its last legs

The thing is becoming increasingly unresponsive when something tries to wake it from deep sleep. A few weeks back someone tried to call me, and the screen turned on and flashed the dialer app, but the touchscreen was unresponsive. I'd click "Answer" and it wouldn't register. Clicking it repeatedly, clicking anywhere on the screen, trying to turn the screen off and on, nothing would work. The phone basically froze, only not exactly, because the sound was still playing. Like a minute later, I held the power button down and got the shutdown pop-up which seemed to rouse it out of whatever infinite loop it was stuck in.
This morning, it happened again when my alarm went off. I could not get the damn thing to stop. It happened again an hour later. When I tried to hold down the power button, the phone reset.
When it came back on, a bunch of my settings had been reset. It reverted to the default keyboard and started showing me tutorials like it thought this was my first time powering on the phone. Additionally, the System Updates menu shows I'm on the latest version, but all history of past updates has been wiped out.
I'm getting really concerned that this thing is gonna die on me any day now.

How about factory resetting the phone, starting from scratch re the software installed? Yes, you'll need to reinstall your apps and reconfigure it, but it's like starting fresh. If it still malfunctions, then you can look deeper.

Thanks for the advice, but I ended up grabbing a Galaxy S8+ off a friend for very cheap. So, not really an issue anymore.
