[Q] Frozen Screen

My LG Nitro will boot up, but the touch screen is not functioning. The power button turns it on, the lock screen appears, and notifications pop up in the upper corner, but it will not react to any touch.
It happened a couple of times before but a few battery removals did the trick...not any more...
It will not unlock...What do I do?
I searched around and it doesn't seem like anyone else is having this problem. Thanks!
Did you try a factory data reset?

You might have a bad digitizer.

Lg G3 screen stuck on boot screen

Very strange problem. I have a LG G3 D855 for 1 and a half years now(rooted)
My phone was at a very low percentage, and I heared it go out. Happens to everybody, nothing strange so far.
I connected it to the charger and I turned it on, i heared the startup noise, but nothing happened. No pincode screen or unlock screen. Stuck at LG life is good screen. I actually was able to take a screenshot, i heared that sound when pressing power and volume down key. I know it is just right away from the main screen, but why is my screen freezing at startup logo? Tried to hard reset and clear all data, then I get a secure confirmation (verify) error. then my led starts to flash red and blue. Battery taking out and still no success.
How to fix this? Also screen is recognizing touch at the startup screen (when it fades away i click on it and it turns brighter)
EDIT: I blindly went into whatsapp and i am able to type and answer calls blindly wtf. Now I got a blue screen, everything is operational, the screen is blue now
Phone is functional, the screen is stuck on boot (life is good screen or blue screen)
How to fix?
Lol, the day after I hit my phone on the screen and restarted it and it worked again! I really dont know how it works again, but lmao! Also my secure boot sector is not working, that problem has nothing too do with this fixed one.

Screen Flickers

Hi Guys,
Everytime I press the top part of my screen (front cam, ear piece part) the screen flickers and sometimes it shows a horizontal line anywhere on the screen and it only happens when i press the top part screen.
I ran a LCD test using #*808# and the screen is fine. It's just happens when pressing the top part of the screen. Even when I'm in the recovery mode and pressing the top part of the screen it still shows lines and flickers.
You guys think it's a hardware problem already that something might be loose connection on the motherboard?
Tia guys!

It looks like a hardware issue.

Black screen on xt1792

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
