[Q] Lenovo k900 randomly shutting down - Lenovo K900

Hello. I am using the vibe v8 rom, and after having my phone on for ~2 minutes, it will restart. The phone does not appear to be overheating; however, after a couple of restarts I will receive a notice that the battery is overheating and it will shutdown. Has anyone else been having problems like this? How did you remedy this?
This has also been happening for the past two days. It had been happening when I was using the vibe rom v7, but when I flashed it to v8, it appeared to have been fixed until recently.
Another issue that I've been having is that it seems to be more 'sensitive' that it was before. For example, if I drop my phone, or put it in my purse it will shut down. When I got my phone originally back in August 2013, this did not happen, but it has been like this for the past ~3 months.

[Q] GT-I9300: Purple/pink screen flickering/freeze (not SDS) and strange behavior

Hello,
I have an international unlocked Samsung Galaxy S III (GT-I9300) that is no longer in warranty and that started behaving strangely (unresponsive) a couple of weeks ago on Android 4.1.2 (official ROM, rooted with CF-AutoRoot).
After reading several threads here on XDA I believed it was subject of Sudden Death. So I started with a factory reset and rooted the phone again with CF-AutoRoot but after that I still experienced the same freezes and started my mission to try and resolve this using whatever method was required.
I starting with trying the DFG app but to no avail. The freezing was provoked but did not go away after many days of iterations and freezes (it always recovered out of a freeze).
Next I tried the eMMC check app to verify on what version I was so that I could help my in further pinpointing the problem. It said I was safe, but while running that app the phone freezed again but this time the screen turned purple/pink and it did not recover from the freeze after several hours until I finally removed the battery. The purple/pink turned into purple/pink with black lines and after removing the battery I could not power on the phone.
In all desperation I started trying out different "SDS-safe" custom kernels, ROMs and bootloaders (all flashed using Odin on my laptop) but the problem did not go away. In fact, I discovered a very strange correlation between the time that I leave the battery out the phone and the time it takes before the purple/pink freeze occurs again.
If I wait half an hour, put the battery back in the phone and boot it (in whichever mode) it would freeze/flicker/die after about 20 seconds. If I would wait several hours, put the battery back in the phone and boot it it would freeze/flicker/die after a solid 1 or 2 minutes.
Whether the phone is connected to the laptop or not makes no difference. I also tried with a different battery but the same behavior occurs.
After waiting a solid day, in still in act of desperation, I decided to flash the leaked 4.2.2 (I9300XXUFME7) official ROM. But even after a factory reset and wiping of cache I found that the problem still remained.
Now I believe I've tried almost everything I've found on these forums I'm not sure what I can still do. It seems it's not battery, ROM, kernel or bootloader related and it also does not seem a case of Sudden Death (I never heard mention of the purple/pink flickering, and it also never snaps out of the freeze; also the strange correlation between battery out of the phone and time before it freezes is something I haven't read about).
From all the research I've done I've not encountered anyone with the same symptoms (does not wake out of freeze, purple/pink lines appear on screen when freeze starts and keep flickering for hours, there seems to be a correlation between the time the battery is out of the phone and how long I have before it freezes again when I turn it on) and I'm running out of ideas.
I believe it is hardware related (but not a screen issue) rather than software related because the USB connection with the laptop disconnects when it freezes, purple/pink flickering and no recovery; but I have no idea what options I still have.
Before I give up on the phone does anyone have any recommendations of what I can try before sending it to a Samsung repair center?
Attached are 4 pictures to show the typical process after waiting ~4 hours and powering on the phone:
Phone boots OK
The phone freezes and a purple/pink overlay appears
More and more flickering making the screen turn more and more purple/pink
The screen seems to be divided in 4-5 parts
Everything is pink and black lines start to appear
Thank you for your time.
I'd say you need a new motherboard or screen, possibly both - you've ruled out any software causes.
just had this issue
Did you find a solution, given the fact that this happened a long time ago?
I was watching a video and my screen turned pink like the 4th photo you posted.
Now it wont work, get the pink screen everytime is turned on.

[Q] So has your S3's screen ever done this?

It also comes in green, purple and blue flavours:

The phone will be up for a time and then suddenly show only that and become unresponsive. After a while, it'll reboot: the only way to power the device back on after that is to pull the battery for 30 seconds, reinsert it and leave it on charge for a few minutes. Once in a while it will crash during boot as well.
It happens several times a day now. Started a few weeks back, so I returned it to stock and removed the root access. That solved the issue, but it returned immediately after I rooted and flashed Slimbean 4.3 build 1 yesterday (previously ran 4.2.2 build 8).
If anyone has been able to fix something similar, I'd appreciate some tips. The problem has seemingly disappeared after having gone back to stock this morning.
TouchWiz...after getting used to the DPI settings in Slim...blegh :\

Phone reboots and other weird problems.

Hey guys, i'm having problems with my GS3 i9300 which all started on Sunday. I'll try to list all the problems as best as i can and when they started and stopped happening.
At the time of this happening i was rooted and using the cyanogenmod 10.1.3 rc1 and was using it previously for the past month or with no problems and had not recently installed any new apps other than swift key.
Only problem on Sunday was i charged my phone over night for about 11-12 hours and it wasn't full charged and the notification light was red for some reason.
On Monday evening when i was driving home in the evening my phone started to beep every few minutes and it was a beep i had never heard before so when i took a look at the screen it showed the driving mode symbol which i think was like a steering wheel (didnt know it was even on cyanogenmod).
That happened for about 10 mins until i restarted my phone.
Then i got woken up by my phone about 3 times in the early hours of tuesday morning because it just started to play my music for no reason so i tuned it off until it was time for me to wake up.
All through tuesday my phone would keep turning off and back on at random or sometimes if i recieved a call or sent a text or changed a setting but not always and this happened every 5-10 mins or so so when i got home i updated cyanogenmod to rc2 but the same thing happened and at one time it crashed as i pushed a button and the phone was vidrating until it rebooted and went into safe mode (the first and last time it went into safemode with these peoblems) so last night about 11pm i went back to stock using odin and again it keeps turning on driving mode and s voice but only when its on charge.
Sorry for the long post but does anyone know what could be happening? Like i have said i have wiped the phone and changed the rom and even went back to stock and unrooted.
Thanks.
I think your phone touched "bad" memory blocks damaged by EMMC bug,that's why it's acts like obsessed but it will stop when it's will be completely damaged. So I suggest you to take it to warranty service center.

If you are on a fresh 4.1.2 stock rom and the problem only happens on charge then first try another charger & lead. If it is still the same then sounds like a repair is required.

Tablet restarts randomly even when idle.

I've had the tablet z for about 2 years. Bought it new from EE, never really had any issues with it but recently it's started rebooting randomly. It could happen after 5 minutes or 30 minutes it's not really clear. Never rooted or installed any roms on it. Sometimes when it reboots it can take a while for it to get back to the lock screen. Unusually long.
So far I have tried
Fully drained and recharged the battery.
disabled the camera
disabled wifi/LTE
reinstalled all the software using sony suite, as well as updates
The tablet works as expected it seems when it is on. It will restart regardless of what is being done with it, in the middle of browsing the web or idle with the lock screen on.
I am at a bit of a loss of how to diagnose the issue or if it's even fixable. I was wondering whether I could get the logs somehow. My other thought is it could be some software that's causing it as when I wiped it google immediately reinstalled the apps.
Make clean reflash with Flashtool or restore with pc-companion.

Is my hardware dying?

Hi guys. I'm currently posting here, because I've been facing some kind of extremely strange behaviour on my L9.
Basically, yesterday, I've tried up to 15 times to flash a ROM without luck, AROMA Installer got stuck at 0.00%. I had to remove the battery, and then, bootup again to recovery those times.
16 times later, the phone has decided to flash, for some reason. Also, it seems like the "framebuffer?" - correct me if I'm wrong, got stuck at the last on time, the one before I unplug the battery, getting that in mind, the screen was flickering the last frame of the recovery for about 1 minute after the reboot.
