htc one m8 black display but still active - Android Q&A, Help & Troubleshooting

hey guys : )
im quite a beginner considering anything about configurating my smartphone... Yesterday i did watch a video with the youtube app and then my display suddenly froze and became black. Since then everytime I push the power button the screens keeps black but you can notice that its getting a little bit brighter. So it's basicly still active but I dont know how to fix the problem. the only thing I tried so far is to reboot (10s power button + volume up) but it didnt change anything. When i plug it onto my pc it gets recognized instantly.
Could anyone of you tell me how to fix my problem?
greetings

[Q] Strange screen problem

Hey, I was just playing with my phone this morning and noticed a strange problem... The top part of my screen, just under the notification bar, does not respond when touched, if an app is running. For example, I cannot hit the location/search/layers button in gmaps, or the search button in market (this is only in portrait mode btw), but on the main screen, it responds just fine. This problem did not exist yesterday either, and I have already tried rebooting, and that did not fix it...
Might want to provide a bit more info if you want help.
I.e. What rom are you using, what kernel, any speedtweaks, etc.
Oops, sorry, it just seemed to fix itself randomly, but I am running CM7 1.2/MR2 radio, no other tweaks, just in case anyone else has the same issue in the future...

Im hoping it was just a fluke for you, but keep an eye on the issue, if it happens more it would sound like you could have a bad digitizer (its what controls the touch screen)
So it happened again today, not sure what set it off, but this time it wasn't just the top part of the screen. Phantom presses would happen, the notification bar would go halfway down and then pop right back up, the 4 buttons on the bottom wouldn't respond... I did a battery pull, and it seems to have fixed it for now, should I be contacting verizon to replace this one? It is a replacement of my original one (which bricked)...

[Q] Titan Lock Screen Issue

Hi All,
My Titan has developed an annoying issue coming out of the standby / lock screen.
After the phone has been left and has locked it self, I press the power button to light up the display. Then when I try to slide the lock screen up nothing happens, the phone does not respond. This is also true of the buttons on the front, camera, and volume button. No response.
After a while the phone will start to respond again.
I have noticed that the phone updates email and message icons whilst its not reponding. Not sure if that is WHY it is not reponding though.
I have read that installing the facebook application from the market place can cause a similiar issue, but I do not have this app installed.
Has anyone else seen and/or solved this issue before?
What should i be looking at to cure it?
Thanks
David

[Q] Sreen freeze? hardware or software problem?

Hi there to everyone, I broke only the glass on my screen couple of weeks ago (it felt face down from about half a meter, thats stupid) and I change only the glass my self but since then i have a problem with the screen like: if I press a bit harder anywhere on the screen for about 2 sec the screen became irresponsible and also the back and menu buttons, home and power button work normal. If I press the home button it react as it should, it goes to home screen, so it's just the screen frozen on touch and I have to lock and unlock the phone to go to normal. On daily use it's not such a big problem as i don't press the screen too hard, the problem mostly occurs when playing games.
I would try a hard reset but I not rooted as I use some apps that don't work if I'm rooted and I can't save all my settings, saves and apps and personally I hate to reinstall everything back again.
I'm thinking this is a hardware problem but why it goes to normal only after lock/unlock procedure and i also find on a forum that this can be from the screen protector. It's something similar with the phone in this video the difference being that mine it freezing and that it moving by itself. youtube.com/watch?v=isBDKgxB5vs
Did anyone also experience this?
PS. I sorry for my english as it's not my own language but I'm trying to make my self clear as best as i can, Thank you

You might have the same problem, and this is the possible fix.

Thank you SOOOOO much, this fixed my problem with the fake hang at boot. I remembered having disabled the optimized backlight, i don't even know what this option is supposed to do
Whatsapp audio file problem still there
Phone call black screen issue gone :laugh:

M5 boot stuck half-way, rest of screen black, shuts off after a min

Hi all,
I got this Xperia M5 that's been giving out warnings about memory being full and I suppose it finally gave in. It only partially boots after like a full minute of showing you those blue waves. When it 'boots' the screen is black and nothing works, except you can see the status bar with just the battery icon, no-SIM icon and the clock.
Weird thing is when the device is powered off, you can press the power button once and it'll display a large battery indicator which shows the percentage normally-- I've seen this go up from 0 to over 90 something incrementally.
But when it's 'on' the way I just described, the battery is always at 0% with a red ! next to it.
Anyway, when it's in this weird half-life mode, you can actually pull down the notification bar normally, and tap stuff as well. Flashlight works, you can see an actual WiFi list (nothing happens when you connect) etc. When you launch stuff through here though, like settings, it won't open anything. It'll make the sound as if it's launched something but the remainder of the screen will still be black.
Using the dedicated camera button, I can access the camera. It works (sort of), meaning you can see the camera display where the screen used to be black. And it immediately says "system process is not responding," so I'm guessing this is a system issue where it can't load basic stuff like the homescreen?
Whatever you do or don't do, it stops responding after a couple minutes and shuts itself off.
Stuff I've already tried:
- Safe mode (volume down + power), just 'boots normally'
- Recovery mode (volume up + power) done that for over two minutes, does nothing or just 'boots normally'
- Hold down the tiny yellow 'off' button under the SIM/SD cover, did nothing.
- Xperia Companion: PC won't recognize the phone either in that zombie state, or when it's off, so I tried 'device cannot be detected', shut phone down, held down volume down button, connected USB still holding down, waited for a while and viola, nothing happened.
It's factory OS, never messed around with it and I don't know the version (could be 5?).
Any ideas?
Guys at this point all I'm wondering is if anyone ever managed to brick a phone that's as semi-responsive as this one, in the history of bricked android phones anywhere.. I mean how could it be bricked when you can (sort of) boot and even open the camera?
you said it boots in download mode?

No I wouldn't say download, it's weird-- there's the status bar at the top and soft navigation keys at the bottom, but the homescreen in between these is black. I tried tapping this black area to see if stuff is there logically but you just can't see them, but there was no interaction, no sound or anything.
I am able to pull down the status bar to reveal the usual buttons and such, like I mentioned before you can turn on the flashlight, click to see a list of available wifis etc. But you can't access settings through here, I mean you tap settings and the main part of the screen is still black.
The only way to get the screen to work is to open the camera through its dedicated button, where the camera display works normally, you can switch cameras etc. Tried accessing the gallery through here but it didn't work.
I just don't wanna buy a new phone when this one doesn't seem bricked at all. If it like didn't respond at all and nothing appeared on the screen I wouldn't think twice before buying the first phone I see on Google.
im afraid that you have to flash stock rom again if you will boot into download/fastboot mode.but your problem seems strange.what was the last thing you have done before phone stuck like this?

Not my phone but it'd been going on about low memory for a while now. I got the PC to recognize it once in that zombie state, so I'll try that with Companion if I can get it to half-boot again. I'll post updates if anything happens.
