My screen randomly switches/flashes on and off.... - XPERIA X1 Q&A, Help & Troubleshooting

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

Powering X1i through USB -- any hacks to do the following...

Hi all,
I frequently charge my X1i through USB. There are 2 problems with this method, however.
1) The device goes into USB drive mode, disabling my SD card apps (I keep them on SD card AT ALL TIMES due to frequent backups/restores)
2) Screen does not turn off! while connected to computer! The screen only dims, but does not turn off.
WITHOUT resorting to a) plugging into wall outlet b) connecting to Activesync, is there any to fix these behaviors?
Thanks!
just let it go into activesync mode, that way you can still access your files on your phone and micro sd card from both your pc and phone. And if you dont like the screen not turning off, they just change the settings or just press the power button, to shut off the display.
I know about the power setting, but when your computer is connected to the computer via USB, it refuses to turn off the screen (only dims it)
what? one simple button press and the screen is off. the device is still visible to the pc. I do it all the time - r3a generic uk rom.
in power options u can set after what time it disables screen... default is never

Weird. When I'm connected to Pc, it dims the screen, it does not shut it off. Also, it does NOT auto-shut of screen after the 2 minutes specific in the Power options
You can also use "safely remove devices" to disconnect the data connection from the phone, it'll still charge.
There's nothing we can do AUTO. But like said before, a simple pression on the power button will do it, or you can use My Mobiler and press F11 on your PC.

Yep, I've had 5 different WinMo devices since '05 and they all worked as expected except the X1. I like to use it as an MP3 player at night, Pocket Player has a sleep timer built in so I just like to leave it running as I drift off most nights. But if I do anything, change the volume, rewind, anything at all the screen comes back on and stays on until I hit some other button to turn it back off. All my other devices obeyed the settings you set in the Power tab, but not the X1...
I'd very much like the screen to auto-off if I tell it to while on USB power. It's not only wasting power, but it wakes me up and gets me fumbling for the tiny power button at 2 in the morning. Any fix would be greatly appreciated.
Thanks,
Peter
I bumped up thread: http://forum.xda-developers.com/showthread.php?t=561832 Since it has a better title and shows the exact same unresolved issue...
Reg Fix
Adding this potential fix here as well so anyone subscribed to this thread sees it.
Ok, I think I have a fix for this. I googled around some more and found that this might be an HTC problem more than an SE one. There were various registry keys people suggested to try to fix the 'backlight problem' - which may or may not be related. None of those suggestions seemed to work, but I kept changing keys myself and eventually found this seemed to do the trick.
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Power\Timeouts\ACUserIdle: 120
I confirmed that changing this value affects the amount of time before my X1's screen turns off - but my MP3s still play with the screen off and my phone wakes on receipt of a new call. This value is the # of seconds before the screen turns itself off (in this case 2 minutes). You do need to soft reset for the change to take effect.
This doesn't seem to be posted anywhere else that I've found doing this to fix this issue issue - I changed a few other registry keys as well that might be enabling this fix. So anyone with this problem, please do give this a try and if it doesn't work I'll post the other keys I changed as well - and if it does then post to say so and we're good

Update: I tested it also while hooked up to the computer and it does work with the phone accessible through active sync with the screen off and the battery charging (faster now that it isn't competing with the screen for power, except for the 2 minutes before it times out). If I want to use it I just click a button and the screen stays on till I leave it alone for 2 mins and it remains off. Get a call or a message and the screen goes on for 2 minutes and then off - Exact same behaviour on AC and USB - exactly the behaviour I wanted .

Screen won't timeout

Very odd...
My screen won't timeout anymore, unless I manually press the power button. It doesn't matter whether the phone is plugged in or not, and it isn't dependent on the screen I am on either. The screen just stays on forever.
Is there a way I can see if a certain program is preventing the screen from sleeping? Has anyone encountered this type of thing before?
Thanks!

Did you check the screen time out settings, maybe you got it at 30mins ?
Yeah, it's set to 30 seconds. It must be some program that tells my phone not to sleep?
Even more odd...
It fixed itself!
Rebooting the phone for the last couple days had no effect on the timeout issue I was having, but doing it this afternoon somehow resolved the issue.
Add this to the list of idiosyncrasies that my SGS has.
I'm having this annoying problem with my SGS (JPY) at the moment. Sometimes it'll go to sleep and turn off the screen by itself, but 9 times out of 10 I have to manually turn it off with the power button.
Has anyone else experienced this with JPY? I'm reluctant to wipe and start again, but it's really starting to piss me off now...
might be an old topic, but i am experiencing this right now
i just installed gingerreal guerilla version yesterday and it works fine
however when i connected my phone to usb for charging this morning, it wont turn off the screen unless i do it manually by pressing the power button
weird thing is as far as i remember there's a setting on USB debug mode to turn off the screen when connected to usb. i think it might be related to the rom or is it always like that on gingerbread? i assume that is the root cause,
although i couldn't post the issue directly on the gingerreal thread due to minimum post count.

[HELP] Display glitches/black screen

Greetings,
I'm not experienced with android devices, so i thought i'd ask here first before trying to do anything.
Since a few months ago some weird things started happening to my X8 - random display glitches and blackouts at completely random intervals (sometimes one or even two a day, sometimes it can last two or more weeks w/o an incident, i haven't figured out any relation yet).
Glitches manifest in distorted view on screen - shifted up/down/sideways - or colored graphics artefacts - up to completely bizarre patterns of random-colored pixels covering the whole screen. Weirdly enough, pushing power button as if to lock the screen usually alleviates the issue, sometimes i need to do it few times to remove completely, but it works. Touchscreen works fine, but i need to tap the "right" spot on the screen, not where it's displayed on the screen ("right" as in where the element is when the screen is not glitching).
The other issue (may be related) i'm having with the phone is random screen "blackouts" - the screen goes completely black and the power button cycling doesn't help - but the phone still reacts to screen input (i.e. i can unlock the screen by dragging the slider, launch app, start/stop music playback and so on). I can see the backlight on, so it's definitely screen/gfx hardware issue, not backlight. If i try to reboot the phone, it hangs on either shutdown or boot up. Removing the battery, placing it back and booting the phone up doesn't help - it vibrates as usual, i see the backlight go up, but screen stays black and i can't interact with the phone even if i leave it there for a few minutes (which is more than enough for it to boot up - it usually takes ~30 seconds till full boot). Also the backlight won't go off. It usually helps to boot normally if i hit the phone with a palm on the back side and/or leave it alone for a while. This issue is much more rare (only had it three times), but it puts the phone out of service for a while, so it's an issue for me.
Now, the device info:
Sony Ericsson Xperia X8 E15i
015 baseband
10W44
Unlocked bootloader
Alfs8 kernel (2.6.29.6-Alfs v08a 24/03/2012)
GingerDX v026 ROM
No cpu tweaks done, cpu governor "ONDEMAND", cpu speeds 122-600.
The glitches started when i was still using the older version, GindgerDX v013 with locked bootloader, i have done factory reset and flashed a new version with new kernel (and unlocked the loader along the way), but apparently it did not help fix the issues.
I can't provide and screenshots/photos of the issue because the only camera i have access to at most times when it happens is my phone one and, obviously, i can't use that in this case
The question is: can i still try to fix it by myself (i can do it if it doesn't involve disassembling the phone completely - i don't have the screwdrivers required) by software tweaks or other techniques or should i reflash stock kernel/rom, apply for warranty and hope they find the defect and fix it? I really do like the phone. Or, maybe, you have encountered anything resembling these issues and may shed some light on what's happening.
Appreciate any input in trying to figure out and fix this.
Thank you if you have read all this even if you can't help me, cheers!
1st problem could be 'Screen Cut' issue which is solved using kernel without FPS Cap...
2nd problem usually happens on my phone with miniCM9 3.0.2 but shows splash and boot animation...
Can you see the splash screen and the bootanimation? Because my friends' Xperia Ray has the issue on official firmware... so it could be hardware damage...
Try unlocking the screen then press the power button then press it again...
and also try flashing the stock firmware... If it doesn't work... I think you should live with it...
Sounds like a hardware problem to me. Reflash stock kernel and ROM and full wipe and then flash a different ROM and see it it still happens. If it does I think it is advisable to send it to Sony for repair.

Thanks for your replies, i'll try reflashing the stock rom and see if it still happens.
@Lily48: no, no splashcreen or boot animation, just black screen and visible backlight.
I have the same problem and I checked it many times and my conclusion is....ITS A HARDWARE PROBLEM NOT SOFTWARE..

Well, notify me if you find a solution, thanks
Sorry for double post, but this is important update:
My phone died this morning with the permanent black screen syndrome. Until i rebooted i could use it to receive phone calls or even listen to music (i knew where to touch to activate the features). However it would not boot sompletely after restart, even if i leave it for ~hour. Connecting to flashtool showed that it does boot to a certain stage, but no GUI (for user interaction with haptic feedback) available - the flashtool does show that device connected with usb debugging enabled.
I reflashed the stock ROM, now it's apparently stuck in some sort of bootloop - it keeps on connecting and disconnecting. But the screen is still black, with backlight. If i remove the battery, replace it and just connect to pc w/o trying to boot on, it acts normally as if trying to charge - backlight activates for a few seconds if i touch a key and green led is lit, but still the screen is black.
I will RMA it tomorrow, thanks for help, hopefully i'll get a new one, or they'll repair this one so it does not glitch on me again. Anyway it was/is a good phone, i absolutely love it.
Wish me luck =]

It is a hardware problem and Sony Service Center is the last option you have.. if your X8 is in warranty period.
I did the same and they replaced its display with new one.
Hello, reporting back in:
Just got my X8 back, it really was a hardware problem. They changed the screen now it works as good as new =]
Thanks everyone for support

[Q] Does your HTC ONE M7 do this?

When going to bed tonight do these steps.
1. Put your phones brightness display on the lowest setting
2. Plug your phone in for an overnight charge, do not "turn off" your phone.
3. Wake up in the morning
4. Click the power button on your HTC ONE M7
Did the screen turn on? Are the Soft Keys the only part that lights up?
I've been able to replicate this problem over and over on 3-4 different HTC ONE M7's. For some reason the phone's display will not turn on in the morning. The only way to get it to is to either hold down the power button for a few seconds and the restart screen will pop-up which activates the screen again. Or, to do a complete restart.
Eventually the screen starts working again like normal after fiddling with it for 15-20 minutes...
I believe this is either a KitKat problem or light sensor problem or both. I do know this issue was never around before the KitKat upgrade months back.

I#ve never run across that problem but I know when I enable "ScreenOn" the screen stays on all night and if I just let my phone sit with screen on (because I fell asleep texting ) the screen will be off in the morning.

with my phone its just a 5 second lag sometimes, and i click the power button again to make sure i clicked it and it instead locks itself back. The third click however, everything works fine.
this has been happening to me for the longest its very irritating, i notice it happens whenever i fall asleep, a nap during the day or when i wake up in the morning its really annoying
Well glad to see I'm not the only one.
I have provided this thread link to HTC and reported the problem. Requested that they chime in if they have any questions.
i had that issue

Yes I had the same issue as the original post.Long story short I ended up sending the device back. The new one didn't suffer from this problem. This was back in October of 2013.
Same issues, it's probably light sensor:

Nope. I already tried the light sensor calibration trick. It didn't work unfortunately. I ended up swapping out 4-5 HTC ONE's before it worked correctly.
yup, I tried the trick as well a few more times and could not wake the screen either. generally I'm tolerant of stuff like this because I assume it is the byproduct of repeated flashing and combo of mods.. but I I recall this happening quite early on in ownership and now it's back. (was AOSP now Sense base). sigh

[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.
