White blank display when waking up the phone - One (M8) Q&A, Help & Troubleshooting

Hi,
My phone's display goes completely white when I wake it up after being dormant. This started happening after I had the screen replaced and a full reset was done, but I am not certain if it is a software issue or a hardware issue.
The behaviour of the phone is as follows:
- Power ON: The phone powers up fine and boots up fine (display works as normal), and I can use the phone (call, text, play games, etc...)
- Now, when I let the phone go to sleep and then I wake it up, the screen goes from being completely off to being completely white. Kinda like one of those "flashlight apps" that don't use the flash...
- Same happens if I let the device go to sleep and a call comes in. In that case, the device wakes up as it rings, but the screen is completely white. If you know where the button to answer the call would be, you can actually answer the call though... So the screen is responsive, it just isnt displaying anything
So, I am looking to see if anyone has seen this in the past and what the cause may be. This happens with either the HTC ROM or Android.
FYI, the shop that did the screen replacement is not taking responsibility, so yes that sucks, etc... etc... No point discussing that.

Flashing Screen On/Off During Phonecall

Hey,
Theres a thread about this, but I cant find it, even searched for it, so here it comes again:
When I make a phone call, the screen flashes on and off (lights on the keys aswell go on and off) - This is annoying because the screen doesnt respond when its off, and just flashes on and off until your about half a minute into the call.
This means touchtone services and ending short calls may be a pain sometimes.
Any solution?
Thanks
The screen will go black when up against you and then back to normal when moved away, it has a light sensorbuilt in.

Possible SOD issue...

Hey guys so my Tilt 2 has been having an issue when I put it to sleep. It goes to sleep fine, but when I wake it up the screen remains black. The actual device turns on, but the screen stays black. I can still make calls, receive calls, play music, etc. but I have to soft reset the device if I want to be able to see what I am doing.
From what I can tell my problem is different from the normal Sleep of Death issue where the device simply won't wake up.
I've searched through the forums looking for solutions and have tried pretty much everything from doing a hard reset, using different roms, formatting the internal memory, etc. Even after doing all of this, my device still suffers from this issue.
Any insight into my problem would be greatly appreciated!
I assume you've tried a simple reset using the reset button or pulling the battery out and putting it back in?

Yeah every time I the screen goes black I soft reset it in order to get the screen to turn back on. The problem is that the issue persists through soft resets. I currently can't suspend my device because I can't get the screen to turn back on...
hold down the volume down button and then press the reset button (the physical reset button) this should bring you into your bootscreen the multicoloured screen.. if you can get there then you can flash a new rom on your phone... and thats a whole other ball game. It gets a lot of hype as being hard but its really super easy to do if you just follow the directions.
Tilt 2 dark screen solved
With the tilt 2, if the screen does not wakeup, but you can answer the phone, hear music, etc..., it is a malfunctioning light sensor, maybe hardware, or software related (drivers), but it is fixable. Just eliminate all calls for use of the light sensor.
I had this problem and took quite a while to figure it out, as there are several apps that poll the light sensor that cause problems.
First, go to start/settings/system/power/backlight and uncheck the auto adjust backlight option
Second, go to start/settings/personal/buttons/backlight and uncheck the enable keyboard auto backlight sensor.
Last, open advanced config (need to download and install from touchxperience.com, if you do not have it), tab to light sensor and set light sensor polling to disabled.
Now, my phone works normal and will wake up properly from standby like it should. this all seems hardware dependant, as I have in my family 3 of these things and I dropped and broke mine, so bought a new one (4th in the series) and it had the SOD issues, but could restart with softrest. Took me the better part of the day to find a reliable fix, but now all is well again.
Hope this helps other Tilt 2 and similar issues.

Display Graphic problem

I've got a problem with a OneX I'm trialling for work.
This is a stock device with the latest OTA update applied. I installed Good for Enterprise, activated it, and got my work emails. I opened a PDF attachment which opened for a couple of seconds then the display glitched.
The attached images show what I mean. The display is glitched for every screen. Soft resetting the phone was okay until it started again a couple of minutes later.
Soft resetting a 2nd time was where my real problems started. The phone vibrated as it started, but the display stayed dark. If I tap the power, the touch buttons light up. If I go through the motions of the lock ring and my gesture lock, I feel vibrations of my actions but can't see a thing. If I ring the phone, it rings, the touch buttons light up and the LED blinks. The display stays dark at all times.
Does anyone have any idea what's going on here? It's almost like when a graphic card overheats in a PC.
I would try a hard reset, see what that does, it should fix it as it looks like software problem
Squeeze your phone between thumb and forefinger (on the screen and rear cover) about 1.5-2cm in from the USB port, and slightly below. Let us know if the screen comes back on.

I think your phone is on drugs.
Seriously though, that's the scariest gfx bug I've seen on a phone.
Work were just as surprised as everyone else.
It's been sent back to them so they can talk with Vodafone about just what's happened with it.
In the few days I had it, it's a decent phone. The primary reason for considering the OneX is the screen size, and the fact you can read a PDF clearly on it.

Mine looks exactly the same once Ive had a few whisky's...
I had the exact same problem, so I shipped off my phone to service.
They actually changed the whole motherboard. I got my phone back 2 days ago, and it is working better than ever. Even better than before they changed the board.
My guess; Same problem as me. Busted motherboard. Im waiting to get a reply from the service guys that fixed my phone, so I can get some solid answers about what was actually wrong.
Hope this helps!
Best regards,
Sebastian

After dialing a number, phone locks up (black screen) until the other person hangs up

my phone locks up every time i dial a phone number. the screen gets locked up (black screen) and even if i press the home button or the sleep button, it won't come back on. the only way it would comeback on is if the other person hangs up the phone. for example, i call 611, now as soon as i dial that number, the screen goes BLACK. nothing shows up on screen. only choice i have is to WAIT for the other person to hang up for my screen to light back on again. i can't hang up because the screen won't come back on until the other person hangs up. if i press power button, nothing happens. something if i press the home button. what is wrong with this phone?
btw, it is running lean rom. i previously had another rom (samething happened on it tahts why i'm on lean rom, and same issue).
i'm currently downloading the stock tmobile rom, lets see if this issue is resolved. if any of you have faced this issue please comment. thanks.
also, when flashing the roms, i always follow the correct procedure (recovery > wipe data > wipe cache > wipe delvic > install from zip. )

I'm having the exact same issue, when I make a call the screen guess into sleep that can't be awaken unless whoever I was talking to hangs up. the only exception is when I'm in speaker mode but I would have to be quick before the screen guess black. I'm running ogwisdom's paranoid android and I flashed from stock Rom. any help would be greatly appreciated.
Sounds like your guys' proximity sensor isnt functioning properly.... it controls the screen dimming during calls by detecting our face. If it's not detecting your face properly, then when it thinks you have put the phone down (always) it will dim the screen and keep it that way until the call is completed like you described...
This happens often to some of us who have screen protector covering the sensor.
If the sensor is actually broken obviously you will have to replace it, but more likely its just being blocked by your screen protector or fingerprints?
You can just disable the proximity sensor like many people do. It's really not necessary anyway imo..
To diable it go to the "phone app" where your dialer is just bring up the menu, go to settings and uncheck the box that says "detect your face during calls and dim screen". Then you can just use your power button to bring the screen on and off during calls. Proximity sensor kinda worthless anyway...as far as I know.
Anyone know what use the sensor has other than screen dimming during calls? Theoretically I think it controls dimming at all times, but by default the dim kicks in after what 30 seconds(?) and who looks at their phone for 30 seconds without touching the screen unless a movie is playing (in which case auto dim is disabled!). So thats why I kinda think the sensor is useless...unless its doing something I dont know.

You can replace the sensor if its broken cheaply,
You can remove whatever item is blocking the sensor if its being block
Or you can just disable the sensor like many people do. It's really not necessary.

[Q] Variety of strange screen issues occuring

Apologies if this has been addressed before, but I searched and couldn't find something exactly like this...
Randomly one of 3 screen issues seems to be occuring on a daily basis:
1) Auto-Rotate stops working. Cannot get screen to rotate without reset (Yes, I've made sure auto-rotate is on in settings)
2) Screen will not Auto-Off. Even if I change settings to 15 secs, screen will not turn itself off. I have to manually turn it off. And, if I receive a text or any kind of notification it will light up again and stay on indefinitely.
3) Screen will not turn back on when trying to wake up device. Hitting the home button and power button both have no effect. Although the LED is usually blinking, and it seems the phone is still on.
For all 3 of the above issues, manually pulling out the battery and reseting the phone that way seems to always work. But, this is an annoying process to have to go through on a daily basis.
Also, I've noticed that these 3 symptoms don't occur simultaneously. For example, yesterday it wouldn't auto-off, but rotation would still work.
Not running any custom ROMs either
