My screen randomly switches/flashes on and off....

It's quite obscure... while the screen is switched off, it arbitrarily switches on, but within a split second, it switches off (causing a flashing effect). Anyone else experience this? Any solutions?

My girlfriend's xperia play does the same thing. while the screen is turned off, her phone will turn on as if you were to press the power button, then turn back off after about 5 seconds, and will keep doing that for hours. ive been trying to figure out whats causing it but i have no clue. did you ever figure it out?

simple,
1. diagnose what's ur phone problm...
- flash it to original ROM / stock ROM or any recommended ROM
- if problem still --> h/w problem
2. if u had xperience in disassembling phone, try to disassemble it, and see if something broken. 1st priority, check flex cable since it is usually broken. if nothing wrong --> service centre is least option

[Q] Xperia Z Died Randomly?!?

I'll started off by saying that my bootloader is unlocked and I have flashed the Android 5.0 ROM (503b) from here: http://forum.xda-developers.com/xperia-z/orig-development/exp-lollipop-xperia-z-t2929369
Sorry if this is a bit long but I thought it'd be best to tell you the steps leading up to the potential death of the phone.
As far as I can tell the issue doesn't stem from a software fault as I've been running the ROM solidly for 2 weeks now with no issues apart from not being able to hear a call when I accept with something plugged in the headphone jack.
I wake the phone and go to unlock it and the touchscreen is unresponsive. I have known it to take a second or two to wake up so I gave it a minute then tried again.
No response. Screen hadn't dimmed either so I suspected it had crashed.
Held the power button and the power off prompt appears along with all my previous actions unfolding beneath it. Just for good measure I decide I'll reboot the phone as I sometimes do when it starts to lag.
Powered off fine. Go to turn it on and nothing happens.
Battery was on about 20% when I turned it off so I plugged it in and tried again.
No LED light when I plug it in, still no response to any button combination. No recognition over USB either.
So I'm going to leave it plugged in overnight as I've seen it recommended by a couple of people before. Just wondering if anyone else has had this happen and if you managed to recover the phone?

Unfortunately no. The phone is doing absolutely nothing when any key combination is pressed and i've tried plugging it in via USB and doing these in case the LED light had developed a fault. Still nothing.

Nexus 6 Screen Won't Turn On, Rest of Phone still on

Figured I see if anyone else has had this issue. I went for a walk with the dog yesterday, and was listening to music on my Nexus 6 the whole time, and when I got home I couldn't get the screen to turn on. Music was still playing, it was still connected to my G watch, and holding the power button triggered a vibrate when the power menu opens--but the screen was completely black and unlit the whole time.
Had no prior issues, just wondering if anyone else has had this issue. Figuring I'll probably call Motorola as this seems like a hardware issue...
Any suggestions would be well received!

Try holding the power and volume down buttons together and see if the screen will come on when it reboots to the boot loader. Alteratively you could try to power cycle it by holding the power button down for 30 seconds. Hopefully Motorola will also be able to help you.

me too
same exact thing happed to me music pulled out headphones the phone still works but the screen is dead. I can pull to use phone and **** and have the same vibration. holding power for 20 seconds is a no go. tried tons of holding combinations it seems like I can get it to shut off and on may be but it's just not doing a reset that I can tell that reboots the screen.

you had an sod(sleep of death). it sounds much worse than it actually is. its a rather common issue as well(no fix). try using a custom kernel.

Ambient display fault?
Hey, I had the same issue, i switched off the ambient display and after that the problem is solved. Give it a try, it might help. Go to Settings, Display, and turn off the ambient display .

same problem

[Q] Screen fails to turn on occasionally, but Touchpad still working

Ok, this one is driving me a bit nuts trying to diagnose. My Touchpad has started to not turn on the screen occasionally. If I press power or home, the LED in the home button will light but the screen won't come on. If I wait and try again, perhaps in a minute or 10, it will sometimes turn back on. If it does turn back on, everything is still obviously running, and I am receiving notification sound or vibrations when appropriate. If I do a forced reset (Power/VolDown/Home) it'll reboot and the screen comes on. I'm not sure if this is a software issue or hardware, but I hadn't loaded a new ROM in quite some time (I'm running JCSullins 4.4.4). I had been running one from last year and as part of trying to diagnose this updated to his latest 1/13/15 version http://forum.xda-developers.com/showthread.php?t=2712680 but unfortunately that didn't seem to fix it.
Is it possible the backlight is failing? If so, is there a guide on how to repair it? The unit still does most of what I use a tablet for albeit a bit slow (and battery life is starting to suck). For everything else I use my phone.

Try completely deleting everything and go to lollipop and try that out.

[HELP] Black screen randomly, have to hold power button to restart

Hi
So my phone has randomly started to die about once every other day. Screen goes black (i have always on screen) and no response from any of the buttons (power button, twice volume down button for camera). I have to hold the power button until it restarts/starts (don't know if it is dead or not). Anyone else has this issue? Only wierd apps that i havent hade before is blockada.

Baddar

Troubleshoot it.
Delete the app and see if it still happens. If it does, flash a raw firmware and completely wipe your device. if it still continues, its a hardware issue and you should exchange the device.

You're in custom or stock rom?

Im on stock with no modifications.

Phone auto shuts down
Did you find any solution same thing started to happen with me twice in 2 days

The way I fixed it... go to settings, Security & Lock Screen, click on the gear icon next to screen lock, then choose the first option Automatically lock, choose "Immediately" any thing other than that causes the screen to go black. I hope it works!

@Ahmed_x this didnt work for me.
So today i was about to miss my international flight because of this stupid phone deciding to die on me while on charging so no alarm went off.
Wtf is wrong with Asus? How could this have gotten worst with the new update. Are their developers ret**ded?
This phone is being returned unfortunately. Awesome phone but if u cant trust it to give a simple thing as alarm whats the point.

It happened to me twice in three months. The smartphone got stuck/freeze in standby mode: no response from the physical buttons or touch. I use the official android 9 rom.
I managed to restart it with the power button and volume up pressed for 15 seconds.
I hope that with android 10 this will never happen again.

Happened to me today, had to hold volume-down + power for about 10-15s to get it back.
very strange using latest firmware too (WW_Phone-17.0230.2004.60)

[HELP] My ROG Phone always turn off suddenly when charge
Please HELP My ROG Phone 2.
It's been more than a month if the charge will turn off unexpectedly. This situation is experienced until today. So that every time I charge, phone must be in the dead state. I've been very frustrated. Already doing factory data reset, only lasts for one week and back like that again.
Worse, in certain circumstances the handphone suddenly dead and hard to be turned on again. When charging the battery, sometimes the phone likes to not fill. I had to unplug and re-plug the charging cable to return it to normal. Its sucks. I bought this phone in a new condition with the official warranty on January. I already did update to Android 10 when available by the system. This issue occurs after the update.
I had thought the charger that I got from the factory was problematic, until I decided to buy a new charger with the original quality with 30watt power. But it turns out the same.

Same here my phone will turn off while charging. And it will keep rebooting. Sometimes my rog will not charge

My ASUS ROG2 is starting ti piss me iff noe.. Everything I play BR in CODM alwaiz black out..every single game black out. This is not good...Is this normal? Every game has to black out?...
