Hey, ive hade my mate 20 pro for about 1 year now, ive never had any problems with it, ive never dropped it, it is in perfect condition with no scratches on it. But, last week when i was watching youtube, my screen randomly went black and started to flash green really quickly on and off, then stops, when i try to reset it using the volume up and power button and volume down and power button combo, the phone vibrates, then starts flashing green again and goes back to black screen after 5 seconds... anyone have a fix?

I was watching a YouTube video, and my Tab just shut down. It did feel really hot on the back, now that I think about it.
But I've tried everything! Keeping it plugged into the wall, hold power for 30 seconds while touching screen, holding for 15 then for 7, Volume Up + Power, Volume Down + Power, and plugging it into the wall. Nothing's working.
I have a Metallic Grey 32GB with the latest TouchWiz Rom.
Please help.
i had the same - it seem to have restarted by having it plugged in the PC and then pressing Power + Volume up and volume down all at the same time ... strange though
I've had it for about 9 days and have used it every single day. Last night I downloaded 2 movies onto it and everything was fine. Today it would not power on one bit! I charged it over night so the battery shouldn't have drained. I ended up fixing my problem by doing the following:
Held the power button.
At the same time, placed a finger on the screen.
Held it down for 15 seconds or more and it booted up!
Not sure why it only worked when I put my finger on the screen.
I ended up exchanging it either way just in case.
i had a similar experience when it looked like the images on my screen was tarring and making really odd graphical errors, and then shut off... but i could see that the backlight was still on.. So i help power button untill backlight turned off.. and then plugged it into the charger and turned it on holding the power down button, which luckly got me into recovery.. i then reflashed the kernel, seems to have been a dodgy flash, but its working now..
My G-Tablet was working great for the last 6 months, the day I bought it, I flashed it with Cyanogenmod 7. Last night I was listening to Pandora, while reading Manga. I set it down and went to sleep.
When I awoke the Tablet was off, still plugged into the AC adapter. And refused to boot. After trying to get into the recovery thinking somehow it bricked itself, I noticed the screen would flicker ever so dimly. So I ripped the back off and unplugged the power thinking maybe it's not really off, maybe it's locked.
Alright, so now after holding the power button down for about 30 seconds it starts booting, I see three birds, the words android, the Cyanogenmod logo and then it goes black. After about a minute of that, I assume it booted. Still starting at a completely black screen I pressed the volume button + and - and I hear the beep boop. Alright so it booted. Where is my VIDEO?
I hold down the power button for a minute, I press the volume buttons but no sound. Ok, it's off I'm guessing. Lets boot again. This time nothing, completely blank screen, until it gets to the Cyanogenmod Logo. The video comes on for about 3 seconds then off again. About 15 seconds later, it comes on and I see the android robot riding the skateboard for about 3 seconds, then black again. It again finishes booting, I play with the volume buttons and I get the beeps. But absolutely no video.
One other thing, is that while booting. It ALWAYS turns on the video for the little robot on the skateboard for 2-3 seconds.
Has anyone experienced anything like this before? I'm totally at a loss, I really hope the GPU is fine.
I miss my tablet
If it turns out to be a hardware problem you should have a year long warranty from viewsonic. Someone who has had experience with the warranty process will have to tell you whether or not they will deny your claim if it arrives with CM7 installed (I haven't dealt with them). If you are able to NV flash before sending the tablet back in you should be golden though.
Thanks for the advice Bret.
I had the tablet sitting on my desk, I booted it up, still a black screen but I could hear the volume beeps. I let it sit there for about an hour, running on battery. And wouldn't you know. The screen came on. It's been working perfectly so far, I can reboot, shutdown, let it sleep ect. Not a single problem. I would absolutely love to know if it was a software glitch, or what. Seems my GPU is fine, rocks 3d apps no problem.
But I know if I don't know what caused this, more then likely it'll happen again and I'll flip out.
Open your gTab up and reseat the cables going into the LCD panel.
You say you have been running CM7 for ~6 months? have you had to reflash you system at all in that time?
The reason I ask is that I have had issues of the system corrupting itself over time, and almost every time I had reflashed, everything seemed to go back to being fine. Who knows... maybe its time to do a backup and flush the system for good measure..
Running stock, latest ota(not ics), with root. Once every few weeks I get a situation where I use the phone, turn off the screen and put it down. Look over a few minutes later and see screen off but realize the buttons are illuminated. If i hit the power button to turn on the screen nothing happens. If i hold the power button the phone reboots. Seems every phone I've ever owned has ended up with occassional random reboots. Just wondering if others experience this to.
Hello everyone,
I got a question. Yesterday, my phone shutdown do to no more battery. Once I got home (about 1h30 after), I plug-it into my computer for a good slow charge. I noticed the led was blinking red instead of staying on, but I though it was due to critical low battery. After 3 hours, still the same. I try to open it but nothing happened. Then, I noticed that when I touch the screen or button, the phone vibrate.
I then unplug and try again, same thing. I try plug into the wall charger, samething.
Then I proceed to hold the power button for 5 seconds. All three touch button start flashing and stayed on, but no joy, still vibrate when touching anything with screen turn off (not just no backlight, no image at all).
I manage to found out that holding the button nearly 10 seconds, it force a reboot and then was OK and charged at 70%.
I'm wondering what's the deal here. Is it a problem with the stock rooted rom?
Thanks

Had and still have an issue today. While driving earlier yesterday, I was listening to music in my car with phone connected on headphone jack. It made a buzzing noise( that came through car audio) , I disconnected and removed battery. I replaced battery and phone will not turn back on at all, will only show both Samsung logo's then go black screen. The phone will only power up for a total of 7 seconds from initial power up vibration on any combination of buttons,or even using a JIG
which went right into download mode.
- If I plug into power source , phone will just vibrate.
- I removed battery and replace, both Samsung logo's will appear then turn off.
- If I hold volume down + power button and place battery in, it will go into download mode. In this mode I can hit volume down to restart but it will just stay on black screen. Also if I hold these buttons down and do nothing the screen will just go black after a few seconds.
- I can also put into download mode to hook up to ODIN using same method and pressing volume up, but will say downloading then shut off.
- I've tried holding down volume up+down and power and it will not go into recovery.
- Odin with recognize it for a second (say device plugged in) and start to download files then it will say device unplugged after a few seconds
I've been looking at unbricking and unrooting threads with no luck. Any help is appreciated.
I don't know about the buzzing sound, but the rest sounds like a dead battery. Are you sure it's charged or that your charger didn't die on you? I don't believe phones brick after the flash is up and running.

Yes I'm 1000% percent sure its not a dead battery and even had it at AT&T warranty center this morning having them look at it. I was trying my luck even though its out of warranty. This issue is like none I've heard, because of the fact that phone actually powers up and I can get into download mode within those 7 seconds, but will shut off after. I've timed it till it powers off.

Am having this same issue with my girlfriends phone just as of a couple hours ago. It's completely stock and just recently received an OTA update a few days ago, she showed me bragging how she can watch videos and do other things at the same time now knowing how much I want a Note lol, she's had zero issues with it other than the battery getting very hot while charging a week or so ago and seems to be very slightly bulging now that I've looked at it. Out of nowhere today as we're walking through a parking lot and she's carrying it in her hand, not even using it, she says something is wrong with her phone and hands it to me with it vibrating every couple of seconds and not reacting to any buttons. I take the battery out and when we get inside put it back in and without even pressing anything it goes to the Samsung logo, black, animated Samsung logo, then turns off and goes back to vibrating every couple seconds. I look up the button combination for recovery and download mode and all that, I try recovery and it does the same vibrate every couple of seconds but never goes to recovery, and if I take the battery out, hold down volume down, then put the battery in it comes up with the warning about installing ROMs and all that, weather I press volume down or do nothing it stays at that screen for maybe five seconds then turns off and the only way I can get to the download mode is to take the battery out then press volume down. I have the Sprint Samsung Epic 4G and the batteries aren't the same but are very similar, mine is just shorter and 1500mAh, hers is taller and 2500mAh. So for the heck of it I put hers in my phone and hold it enough to where it connects and turn on my phone without issue, it boots up and shows 70% on the battery, I now have it plugged in and charging the battery at the moment with no issues. I put my battery in her phone and held it till it connects and it does the same Samsung logo, goes black, Samsung animated logo, then turns off BUT no vibrating anymore. If I press ANY button though as long as it's being held it vibrates every couple of seconds and if I hold volume down while I connect the battery it goes to Download mode but can't do anything and it turns off after about five seconds same as before, still no recovery access either. Heard that there is a power button issue with this phone and for the heck of it I've wiggled and pressed the power button with no charger or battery connected for around half an hour just to see if I can make it better, but no luck.
Hope to hear a solution to this. I would take the back cover off and clean the power button but I'm not sure if that would void the AT&T insurance, not going to try till I know I can get away with it without them knowing because if I can't fix it it's getting sent off for repairs.
EDIT: And sort of following captemo's suggestion I took a metal box, laid a hoodie over it for a bit of padding, then moderately bounced the phone on its power button side (without letting the power button be pressed/pushed, by letting it hang over the edge of the box) for a minute or so as if thinking the power button was stuck pushed in and I was trying to knock it back out, then put its battery back in and what do you know it turns on fine now. Weirdest way I've ever had to fix a phone, but hey it works now so the girlfriend will be happy.

Sort of is about right, glad you got it going. Many will complain about the button still clicking even though button is actually stuck. Many have cited some very simple sounding instructions for cleaning power button contacts with minimal deconstruction of phone. Using swab and alcohol. Run a search in q&a, sure you will get something.

I tried the button with no resolution. I just went ahead and jumped ship and bought Note 3. Thanks to everyone who tried to help out
