In a German forum someone reported same behavior; he was able to solve the issue by removing the display protection film:
As a new user I’m not able to post links, search for “android-hilfe.de/thema/linker-teil-des-displays-reagiert-nicht-auf-eingaben"
i have removed the protection film.
the problem doesnt happen on 1st fresh boot (install ROM)
after a few minutes of operation, then this problem occurs
this will go away after reboot but only 50% of the time before it starts again
Go to Aliexpress for full refund. You will need to send back the phone m

Hi. I also have the same problem in my device. Is there any fix for this now?
I am having this problem too after replacing new lcd from china. The problem was worsened when I put the tempered glass. It still persist slightly even when the tempered glass is removed. Any ideas?

Hello
I received my xperia ultra yesterday from expansys.
I found that sometimes de screen dont respond properly, either or its too sensitive, exemple when scroll de contacts list sometimes open one contact, or when i move and icon in the launcher the icon drops, and i put the same pressure all the time.
Or sometimes its irresposive, in the keyboard if touch the same letter with the same pressure, sometimes register the press,others (1 of every 8 or 10) dont.
I dont know if its a defective unit or its a common issue.
Any help?
Thanks

There seems to be a lot of discussion about our units and their issues or lack of issues.
I have never had a SOD (screen of death) or any sensitivity issues. Not on any firmware..
- Updating firmware probably wont fix your issue.
My advice: I would RMA your unit. (Return merchandise authorization) get a replacement.
I had the same issue and got it replaced, the screen was faulty. A simple exchange and now i have speaker issues, hoping third times the charm.

crap! This has got to be the worst case of quality assurance from Sony. I'm one of the lucky ones to get an actual fully working unit...
One question for you all. Which model do you have? Do we know if there's one particular model that has the majority of problems, or is it mostly random? Hamdogg, you got the C6833 (LTE) and no problems right? OP, what do you have?
I have the c6833
In other words, anyone wuth this issue has solved without replace tbe unit?
For for me replace the unit its the last stand, i buy in expansys and i dont know his policy in this subjet.
Its random sometimes works fine for a while, and appears, i think its about 90% fine, but its a lot of money and if no solutions its imposible life with this problem always.
Curioaly when i received the order from expansys the box was already open, not sealed.
Maybe im not the first one that find that this unit its faulty.....
Really i dont know.

And anothr think.
Almost always, the problem appear more when you just power on the unit, tje first seconds are the most dangerous.
If you use during a while its more dificult to reproduce.

Hi,
After I switched to CM7 I started to experience unresponsive or crazy screen. By crazy I mean it's like touch screen calibration is somewhat screwed and it gets touches everywhere. When I turn off screen and on, it is gone. However it starts again after a while. I noticed that when I get my phone out of my pocket, it gets unresponsive. After I clean the surface and do on/off several times it fixes. Sometimes, it doesn't even get fixed so I have to restart the phone.
I also see that after a fresh ROM installation, issue does not appear frequently. After a while, it occurs quite often and my battery is drained as well. I doubt if that is an kernel issue or hardware. But since it drains the battery, it seems like a kernel issue. Have anyone faced a problem like this before?
Try the raindrop fix. If that doesn't work, you may need to replace your digitizer (or alternatively go back to stock ROM if the problem does not show up there).

Thanks ravilov, I didn't know about that. I downloaded and installed it. Problem doesn't seem to fade away but it usually gets frequent after few weeks. I will see what happens. As you said I'll try stock rom next and if that doesn't work either maybe it's time to change my phone.
Sorry to write to an old thread, but my problem is related.
So, after this craziness I wrote in my first post, my screen get totally unresponsive. I cannot use the phone. I decided to change the digitizer. However, the problem still exists even with brand new digitizer. I'm now wondering could it be due to front camera ribbon? I think that's where digitizer is attached to. Any ideas or suggestions on this?
Thanks!
Either that or the mainboard

I've just noticed another flex cable called earpiece ribbon. I'm confused, which one does the digitizer is connected to?
Earpiece ribbon
Speaker Flex Cable

Please help, i bought samsung s9+ plus yesterday it is exynos middle east edition (G965F/DS) , firmeware (G965FXXU1ARB3)
There are annoying problems of Screen freezing ,touch sensitivity issues and failure to respond most of time .i did factory reset .wipe data and dalvik cache
but without benefit , is it software related and will be solved with next update ??
any suggestion
thank you all
Did you remove the protective screen film yet?
I remember having similar issues when I first got my S8+ soon as I removed the film the issue was gone.
If you have I'd probably look at getting a replacement.
My screen works fine as far as response to touch, I think I have screen bleed though. Posted a video of it in my thread.
I dont have a screen protector
I have the same model and software, no issues on mine. Get it changed at the store you bought it from.

Do yourself a favor: Give it back and get a nother one. One thing: Did you e.g. use a backup to set the new phone up?
yes it was hardware defect at the center of screen and was detected by the dialer code *#0*# and replaced from the store
thank you all
I have insane ghost touch / touchfreeze issues since my display got replaced
I am thinking about ordering a new screen from AliExpress and build it in myself
Anyone can recommend a display from AliExpress ?
Any guides or Tipps For this ?
I bought one With frame one AliExpress about a year ago. No Touch Issues..
The only Issue that i have is problems With my Proximeter Sensor and the Auto-Brightness idk from where the problem comes from the display or frame or has other causes.

I have replaced mine with this one: https://fr.aliexpress.com/item/32914009677.html?spm=a2g0s.9042311.0.0.663d6c374TZe3t
It have small touch issues too, sometimes it opens the status bar when I tap elsewhere, but it's only happening when the screen was on for a long time, and all I have to do is turn off and on the screen to get rid of it, but I still don't know if I can recommend it, because it's still a bit annoying, and I don't play a lot of games on my phone, but if you have long sessions of gaming, like a 20+ minutes PUBG for example, that may be a problem.
Also, just a small reminder to NOT unplug the antenna connector, except if you really need it, and in this case do it with extra care, because those are very fragile and I broke mine by unplugging it while I didn't even needed to. Re-soldering is almost impossible without special equipment, but I managed to glue it and place the motherboard cover in a way that it's still correctly touching the connectors. (This connector is only for cellular data. Bluetooth, WiFi and GPS are using other antennas.)
Hello guys, a friend of mine has a Poco F1 and few months back he had to change the display because the phone fall on the ground. Up until that moment he didn't faced any display problem and he was on custom rom (pixel experience I guess). He bought an eBay screen replacement but the phone started facing random screen freezes (lock/unlock and back to normal), which leads him to buy a second screen replacement from an other seller. The situation got worse with freezes and also proximity sensor wasn't working.
Yesterday he gave me the phone and I found out that it's a known problem with Poco F1 screen. Firstly I fastbooted last Miui global stable 12.0.2 and now the phone seems mostly usable but still some ghost touches are present. Than I checked the LCD type with device info he and discovered to have a fts_ts. Also Proximity sensor works when you press pretty hard on the screen next to the notch.
I think that the proximity sensor is faulty on this screen since with the first replacement prox was fine.
What about display problem?
1) I read about Miui introducing driver update to fix touch month if not 1 year ago so now last official global stable should have all the driver updated?
2) Are there any custom ROMs/kernels which fixed the issue better than Miui? Or did 3rd part developers just include new "screen driver" from Miui in their ROMs?
3) I don't understand the difference among nvt/FTS and EBBG/BOE/Tianma. Last three are display manufacturer but nvt/FTS what does that mean?
Thank you!
P.S. I just tried the proximity sensor test this morning and it was working, than I pressed next to the notch and now back to non working. ?
........ So I found out that Tianma/Ebbg/Boe are the manufacturers of LCD panels while nvt/fts are the manufacturers of touch panels.
I just rooted the phone and from hw info app I can see the combo Ebbg/FTS.
Now I am searching a Tianma/nvt replacement display, if you find one on AliExpress or eBay please link me.
Anyway I still have a doubt about custom ROM behaviour with different panels: does custom ROMs overwrite vendor partition when flashed or is it enough to just flash latest Miui (via fastboot?) before flashing a custom rom to have updated touch driver?
