Hi, I have recently purchased a Mi 9T and everything works fine with the phone, but I have this bug, that I didn't see in any post from this forum.
Every time the screens goes black (sleep), it doesn't recognize any input anymore. The phone still works and I can receive calls, notifications and so. I can turn on the camera, make screen captures, and everything, but only because I can do this with the volume and power buttons.
I tried Flashing the device, but when I get to the recovery screen of TWRP for the first time (where you need to make a swipe) the screens goes black for a second and doesn't let me do the swipe.
Any ideas of what the problem can be? (and the solution if it's possible).
If not just press the power button again ...same things happens to me, once i rebot into recovery it goes black and nothing happens, then i need to press the power button to "unlock" the screen again.
had similar experience: sometime after I lock the device (by hitting power button) and screen goes off, it input my finger on the fingerprint sensors it does not recognize and unlock (not even fingerprint animation actually). Other than this I can still hit the power button so that the screen lights up and then unlock with fingerprint.
But, this is just sometimes, not always.

So recently i start flashing and using langthang's MIUI roms and keeping update and flashing all his new release rom. so couple day ago all of the sudden, i don' know what causes it and how it started it. my red button on far right. pressing it turn on and off the screen.so now when i press it to make the screen go back on from off mode. after i pressed the button the screen light turn on and the lock screen is there but when i touch the screen and try to move the ring(pyramid lockscreen) up to unlock, but the ring is not moving, it like there is no touch screen ability to my phone's screen.
but when i use the green button far left, the button usually to use phone. that button doesnt turn off the screen but it just turn on the screen, this button is working normally. i can move the ring up to enter the main screen.
the screen isnt cracked or any thing, but i do have a protection layer over it which been there since i got the phone and never got this problem before.
what do you guys think my problem is and how can i solve it?
thank you!
It's happening every now and then, but sometimes when I press the lock screen button to unlock the screen, the lock screen comes up but I can't unlock it, it just ignores my finger like if the digitalizer was off. I have to press the button twice (to turn it off and on again) to make it work.
Any ideas?
If I press the power button on my G2, the screen comes on, and goes off after about 1 second. During this one second, I can unlock the screen and do anything but the screen ultimately goes off. the only way to use my phone is to turn the screen on by plugging in the charger, or by pressing power button volume down at the same time. this switches the screen on normally. Tap to sleep works perfectly but tap to wake isn't working. I've tried factory reset. I've cleaned cache partition. I'm all stock no root. Any help would be greatly appreciated! Thanks!
My A3 doesn't "wake up" from stand-by.
If I reset it keeping pressed power up button, it correctly reboots, I can see all boot process and it correctly reachs the starting home page.
If I keep touching screen, open apps, navigate from various menu all works fine. But when I leave it without pressing any button/screen for 10/15 sec (display power off delay) the screen correctly goes black, but there's no way to wake up it again although it seems working. The A3 "under" works because plugging to AC Adapter beeps the sound of charging in progress, PC (Kies or SmartSwitch) detect it correctly; only the screen remains black.
I already tried to wipe and even reflashed last firware with Odin but with no luck.
Is there anything else that I can try (except send it to repair center...)?
Thanks in adv

P.S. When I call It from another phone, it rings but the LCD remains black and doesn't respond clicking vol +, vol - and home buttons
P.S. 2 Thinks become "funny": Home button, vol + & vol - don't work at all. Power button powers off display, but long pressing it, doesn't pop up power off/reboot menu. Softkeys don't work.
Sounds like SoD. Try installing the app "Wake Lock" and choose the PARTIAL_WAKE_LOCK option.
Hi all,
Just got a used LG G6 is excellent condition. Everything is working fine except I'm having a few problems unlocking the phone.
Basically, waking the screen is really hard. I have every possible way of waking the screen turned on, but none of them work.
To get the screen to wake I have to press the power button once slowly, then press it again to wake the screen, then if I press again it will pick up the fingerprint and unlock.
KnockON doesn't work at all, the volume key shortcuts do nothing, face unlock does nothing, and just picking up and trying to use fingerprint doesn't work.
Also, Always On Display doesn't work either (totally black screen)
The power button seems to function fine as I only need to press it once to lock the phone.
Any ideas what might be causing this?
