I have a nvt-ts screen and i have insane ghost touch issues and some times screen freezes. Got my Phone in January and it was manufactured 11/2018. Everything was fine until i got my Screen replaced at the end of february. Since then i started to face ghost touch issue. I dont think i had instantly a ghost touch problem as the screen got swapped. i think it took about 1 month. The replacement was very expensive (120€).
i tried different custom roms, and different vendor images / kernels. Also Oxygen Os.

Sometimes it got a bit better-
The thing that weird is , that when i full wipe my phone and fresh install a rom i mostly dont face these issues for sometimes more then a week.

Hi, my manufaturing date is September, 2018, my panel is NTV

I noticed that if i turn off gesture screenshoot and Miui optimization in developer settings
The touchscreen is back to normal

For keyboard is to turn off gesture swipe

(See Edit) Poco F1 2018.09 Im experiencing issues with ghost touch towards top left corner of device and around left corner of the notch/ Device not registering touches(Viewable with show feedback for taps turned on) had the issue for a few months! Rapidly turning the screen on&off for about 5seconds fixes the problem 9/10 times. Im on stock rom 10.3.7.0 (Pejmixm) stock kernel never rooted and no damage to screen whatsoever. I love my device but this issue is infuriating only issue i have but its a deal breaker, i would not recommend this device to anyone unless your on an very tight budget and sd845 is a must!

Edit: Problem was solved with a software update. Now running on version: MIUI Global 11.0.4.0(QEJMIXM) Stable

This update fixed all screen related issues i was facing from the ghost touches to freezing when unlock.

Date on box: 2019.02
Panel Type: NVT-ts
LCM: dsi_tianma_fhd_nt36672a_video_display

Got screen burn in on my display but will go away in a couple of minute when i stopped using it. and viewing grey picture/background shows purple hue around my screen?

Should i send it to warranty back? My bootloader is unlocked and i just buyed this phone 4 months ago. Also, do i need to reflash stock miui and relock bootloader when going for warranty?

That's LCD image persistence, not burn-in. I also get it on my status bar with signal and time. I think it's normal for LCDs, after almost a year it's still getting back to original color just fine.

To be Honest.....
Now both fts and nvt has no problems at all but when oc refresh screen rate and fps there will be a difference that show nvt is better than fts as the only kernel give 69hz is extreme kernel for fts touch panel which face random freeze which this problem not exist in nvt..! And nvt has now sehstaion kernel which oc too 67 and 69 and even 71 hz without anyyy problems which missed in fts I dunno maybe hardware limitations but I don't think so maybe because of drivers,kernel,vendor,firmware etc I see nice development with open gl and vullkan in the miui11 latest update but fts oc still problem i hope they will fix soon
