Black Screen, LEDs Working - Xiaomi Mi 5 Questions & Answers

Hi,
I'm running LineageOS with MicroG and I can't use my phone since Sunday because the screen doesn't turn on anymore. The LEDs are working and smartphone-connected messenger apps like Signal still work on my Desktop, so I guess it just sits idly, waiting for me to enter the PIN. The screen doesn't respond to touch events, but I can start the camera (at least the phone vibrates when I press power quickly multiple times - I can't confirm because the screen stays black). Other things I've tried:
* Recharge the phone fully
* Restart the phone
* Uncharge the phone (should have done that before I guess… it takes forever to uncharge if you can't use the screen. ) I'm still in the process of doing that.
Could somebody give me advice how I can figure out what exactly is wrong? Thanks in advance.

Phone keeps popping out of suspend

The screen keeps blinking back to full brightness, every 30 seconds or so, when it is left alone and the screen dims normally. It is as if something is pressing a button or touching the screen.
When I press the power button and send it to suspend mode, the backlight goes off, and the tilt no longer responds to touch or button pressing. For some reason it pops itself out of suspend and turns back on every couple minutes. My battery life is going down extremely fast. 100% to 40% in three hours.
Any help would be greatly appreciated. I searched the forum but never found a specific topic for this issue.

I have the same problem w
th the backlight comming on by itself & battery life depletes extremely fast. I am using HD 15 Nov with 3.29.
In addition to backlight issue my hardware keys are no longer working.
Please has anyone got any advice
i have the same problem. the only thing that seems to work is doing the keypad lock and putting it to sleep. it will occasionally blink like its trying to come back on but doesnt. another thing i did is put my phone in flight mode, locking the keypad and putting it to sleep. when i do that it doesnt blink or anything. sadly i wont receive phone calls or emails and texts. i think the blinking has something to do with phone signal and accessing the networks.
hth
also i noticed that it wakes from sleep when the keypad "unlock" screen pops up.
i think i found a fix
Ok I hope this helps for you because it seems to work for me. I first went to start/settings/sounds & notifications. Then I clicked on the notification tab and unchecked everything leaving only the ringer on for when calls come in. when I did that, for about 5 minutes (longest I tested it at) the phone did not turn on and the backlight didn’t do that weird grayish flash thing. Afterwords I at first was going to go down the list of all notifications and turn things on/off to see what wakes up my phone but i got too lazy and only checked one setting. One thing I noticed is that when I have the beam: autorecieved notification turned on for display a message on the screen I get that weird backlight flickering thing. So for now I just have sound alerts on when I receive any type of messages and a sound alert for reminders. So far so good, my phone hasn’t woken from sleep in 20 minutes.

Can receive calls, texts, but will not wake from sleep and no home screen.

Hello everyone. I have had my Droid Bionic since day one and I have never had an issue with it. It has been wonderful.
Until today. I am on the stock OS. I had a Live Wallpaper that showed a little Android figure that melts based on the percentage of my battery. I went into my Gallery and clicked on "Set As Wallpaper" on an image I took with my camera on the phone.
At the bottom of the phone, a small popup showed up that said "COMPLETED". When I went to the home screen, there was no wallpaper in the background. It was just black, though the icons were still there and it was responsive. I thought maybe the image was corrupt, so I went and tried another image.
This caused the phone to reboot. When it rebooted, there was a notification bar, the time, the lock screen, and a thing that said No Signal. I tried to unlock it, but the phone was unresponsive.
Then I got a text message, even though I had no signal. The notification light was blinking. I could not unlock the phone. I hit the sleep button, and it went to sleep. I tried hitting it again, and it would not wake up.
I tried pulling the battery and putting it back in, and now it won't properly boot. Right when it boots, it goes to sleep (the little shutdown animation). I texted myself from my sister's phone and the notification light blinks, the phone vibrates, and the screen turns on and shows I have a text on the notification bar. The screen and the buttons are completely unresponsive, however.
I tried calling myself from my home line and I could pick up the call just fine and end the call. I could not, however, go back to the home screen while on the call. The capacitive buttons on the bottom were completely unresponsive. When I hung up the call (by touch), it went to a completely black screen with the notification bar showing that I had some text messages and the time and my service, etc.
I have rebooted the phone five times now by removing the battery and it keeps going to this. I have never rooted the phone (I wouldn't even know how to) and I am concerned because of all of the information that I have saved on the phone.
Yes I have tried removing the SD card. Didn't help.
Any suggestions? :/
UPDATE: Now the phone doesn't even boot, it gets stuck at the Red Eye spinning logo. It vibrates twice and the notification light begins blinking, meaning it is letting me know that I have received text messages... but it isn't actually booting to the Android home screen. Really strange...
You should fxz back to stock
It will wipe your application data but not you're sdcard info or internal storage
Sent from my DROID BIONIC using xda premium
Hard reset using all three external buttons
Try doing a hard reset - it's one of those things they only tell you about at the Verizon store when you're stuck:
Once you have the phone on and at least responsive, press and hold BOTH volume keys, then hold the power button down for 10 seconds (it's really about 6, but 10 will do it for sure). This procedure can also be done to force a reboot when you load a gnarly application that sux and locks your phone up - without having to disassemble everything and pull the battery.
Hopefully with any luck, you're phone will do a back-flip and come up!

screen wont turn back on unless above 85% battery

I have a G800F,
If my phone is below 85% and id turn of the screen, it wont turn back unless its back charged atleast 85% then everything works fine, I can use my phone till 0% if i dont turn off the screen, when the screen is off everything still works (i can hear it reacting when i press on the screen etc.
Tried different batterys but nothing changes.
Also my menu and back button wont work permanently no matter the battery percentage, the lights dont even turn on (sometimes it flickers) but my home button works.
Tried googling for answers but it seems i'm the only person with this problem.

Sorry for Late response, but in this S5Mini forum nobody wants to help.
I think you should do this:
-Go to recovery mode and look if screen goes black after some time.
If
Yes: Bring to repair
No: Install a custom Rom and / or try wiping Userdata.
Hope it works! Have a nice day.
I have a couple problems myself with the G800Y variant, whenever my phone switches off (shows the idle screen with green battery and %) I always seem to struggle to turn it on. My fix for this however is to:
1. Unplug charger (regardless of state unless like dead or something)
2. Perform the key combo to enter download mode/reset the phone: [POWER] + [HOME] + [VOL-DOWN]
3. Hold until you see something (the logo, the S5 Mini or the CM/LineageOS variant I'm using appears to take some time to perform the download mode entry) THEN release. If it hits download mode, simply cancel/use [RESET] key combo (above) to exit and the phone will automatically attempt to reboot.
As an alternative, pluck the battery out and chuck her back in, seems to be the charger initiating that little animation which causes a block on user input, or something similar, hope this helped

Connect to pc to back your data up. Also does the touchscreen work? And did you drop your phone or something else?
the touchscreen doesn't work
debugging mode is not activated, I cannot transfer my data to the pc.
I had the touchscreen bug for some time and suddenly, the screen did not turn on. The phone did not fall.

If it still under warranty i would send it to where you bought it. Even if you dont have warranty try it because the device should not be broken under normal use.
keep pressing the power button and when your phone vibrates try and hit restart. i know your screen is blacked out but if possible just try and locate. it happened with me too and thankfully my devices' screen recovered. the pop up comes just adjacent to the power button. first option will be your power off and then just below will be your restart.
I already tried
the phone reboots well but still black screen

Screen stopped working randomly, now only notification light flashes.

Hello,
the other day I had my phone on the sofa next to me, working fine, I leave it there 30 min, pick it up, and the screen has all kinds of weird glitches. After a couple hours now the screen is completely blank and whenever I press the power button the notification light blinks a couple times. It's kinda weird tho because touch seems to be working (if I boot to recovery, then tap on the screen the phone vibrates just like TWRP buttons) and I can still boot to fastboot. Of course when I say boot it means that `fastboot devices` shows the device ready, but I can't actually see anything on the screen. I'll try flashing the latest MIUI now, does anyone know what this could be? I mostly just like to know whether I should try changing the screen only or if it's likely to be a bigger problem and I'd be better off replacing the phone entirely. Kinda sad, I loved this phone. Thanks.
