On Lenovo P2c72 i had the latest stock rom (firmware p2a42) and at some point the phone started occassionally flashing a black screen for half a second, sometimes the whole screen, sometimes the parts of the screen (full screen width, limited height-like a box), Then sometimes just freezing the touch screen to be unresponsive (side buttons were still responsive just fine like nothing is wrong).
It's having the latest P2a42 firmware and i just installed TWRP and LineageOS 16, but the problem is still the same. When i inserted the sim and rebooted, the screen became unresponsive, but when i took out the sim and rebooted, it was again responsive. The flickering happens anyway.
Can i do anything to fix it ?
I can test and reply, if you know of possible solution.

using k's rom 1.30b and the phone took a nifty spill. now i have severe screen alignment issues. plus when i turn off my device it does not shut the screen off completly. I can still see the time that was on the screen prior.
ok, so it gets worse. now when the phone boots up there is no display. the htc boot image doesn't show. its just a white screen.
I have got stuck with a strange problem with m8, My screen flickers continuously making it impossible to use, from display display to blue green pink tints and abrupt screen off. Initially I thought this is an hardware problem but this problem does appear in boot up htc animations and on lock screen where it is perfectly clear and sometimes the power button also does not turn the screen on, Once I unlock it the battering starts. And also I can boot into bootloader mode and recovery with absolutely no flicker whatsoever. I have tried with various roms[ Even stock] but it is still the same
However this problem started when I dropped my phone. I'm really confused , Does dropping my phone cause a software problem or is it related to hardware?
Any help guys?
Hi all,
As I woke up this morning and booted my beloved G4 the screen went fully unresponsive. It runs boot normally apparently, but no touch is being registered after boot finishes at my normal unlock screen. No vibration even. No pattern swipe, no camera app, no emergency call. Battery went in and out several times, but it boots nicely again and I`m back where I was. No loop, it boots only once. Double-tap on screen functions perfectly tho, no prob there.
I tried a hard reset w back buttons but it captures a nice screenshot for me. (Funny story: when I pressed just the up and down volumes it boots normally as well.)
USB to PC doesn`t recognize cause unresponsive and locked. Fully stock, no mods, root or else...
I bought it last October on Amazon unlocked international version so it must`ve spend some time on a shelf probably.
Any ideas?
Hi
I got the xt-1710-09 and recently installed the android 9 upgrade which never was officially released for this version.
everything works fine except every few weeks something crashes which results in the screen always staying off. I first considered it a hardware fault since the contacts to the screen aren't that good any more which results in gfx glitches when applying slight pressure to the screen.
Now I realized when booting into TWRP via ADB the screen goes on again and the phone works for a few weeks.
does anybody have an idea what could be the cause?
I suspect the code of the fingerprint sensor. since this code already crashed earlier which resulted in the fingerprint gestures not working any more until reboot.
when the screen is dead everything works fine except well the screen and touch control. which mean the phone is almost unusable except via "ok google" speech control.
using the fingerprint the phone vibrates approval. (not the wrong fingerprint vibration)
but regardless of pressing power button or fingerprint sensor, the screen just stays black.
i believe I rebooted the phone several times via letting run the battery down or pressing the power button for a long time. this did not help. only booting into TWRP always (temporarly) solves the issue.
the phone is unlocked, rooted and twrp installed.
thanx
I have a moto g5s xt1792 after I unbrick trying to install lineage, almost everything is working the problem is the lock screen, after a while the screen goes black, it lights up (with the black screen) I can unlock the screen but if it is just the pin or the pattern the screen remains black after unlocking the screen, if it is with the fingerprint it goes back to normal and I can see things.
there is another problem related to the sensor, the screen does not light up when i pick up the cell phone i have to press the power button for the screen to light up
the stockrom I installed is this one
MONTANA_OPPS28.65_37_7_11_cid50_subsidy_DEFAULT_regulatory_NO_ERASE_MODEMST_CFC.xml
and then I reinstalled this one because I noticed the screen lock problem but it continues
MONTANA OPP28 65-37-7 cid50 subsidy-DEFAULT regulatory-DEFAULT CFC
sorry the bad english and thanks for the attention
--edit--
the black screen appears after a long time or randomly after i lock the screen
I noticed something too, the black screen disappears after I keep pressing the power button to light up the screen a few times and then the screen shows the screen lock
