Please help as the phone can only be exchanged for free within 7 days of purchase. Just need to decide if this is a hardware of a software problem.
Just bought my brand new Xperia Z Ultra two days ago. Sometimes the screen would detect false input (pressed one location, screen detected at another) or non-existent input (received long press input when there was no input).
These incidents happened infrequently and would resolve themselves upon turning the screen on and off or rebooting.
Any insight or input would be much appreciated.
(firmware is 4.4.2 and a screen protector is applied)

Dear all,
I have the following problem; I own a Sony Xperia Z1 and a week ago my touchscreen started doing strange. It seems like the touchscreen keeps touching itself (also known as Ghosttouches). I activated the developer mode on my device and found that all these ghosttouches occur on only one line of constant x (x=539). This problems makes it nearly impossible to do anything productive on my Xperia phone.
Instead of replacing the touchscreen, I was wondering if there is a possibility of just disabling any touches that occur on said line of constant x.
Hopefully some of you geniuses are able to help me
Corrado
Hello Everyone,
I bought my cousin's xperia z2 two days ago its a great piece but so bad for me i couldn't enjoy a full week without problems
the screen becomes unresponsive when i hold two fingers for some time (15-30 seconds), I've discovered this issue when I was playing GTA San Andreas and kept holding the screen, during normal use this issue happens very rarely, but I think what's causing it is when i hold two fingers for some time it becomes unresponsive (tried it on home and other apps its not related to a specific app), locking/unlocking the device fix the issue and everything goes back to normal till i hold two fingers again........ its really irritating and i don't know what to do.
I've tried to boot into safe mode and the issue stills there and I really can't tell whether it's a software or hardware issue .
About the phone :
- Hardware : it has a replaced display and vibrator not working
- Software : no system changes have been made, everything is stock!!
I have a Redmi 5 phone. I had Global Stable ROM than switched to EU Beta. Currently on 8.7.19. I had a problem on both ROM. Randomly my phone slowdowns. Or at least the screen I don't know exactly. I have to press the screen harder and the response can take 1-2 seconds. Locking and unlocking the phone solves it. What can I do to solve this problem?
I have reported the issue. Please confirm it. We need official answers because many people has this. http://en.miui.com/thread-3446668-2-1.html
OK! I'm pretty sure now it's a hardware issue! Flashed TWRP recovery which also had screen freeze problems!!!!!
Than flashed an old firmware 9.2 something and flashed LineageOS over it. Guess what? SCREEN FREEZE!!! It can only mean one thing: it's a hardware issue. It's also explains why they ignore it: because they don't want to admit it! And because this much people has this problem we can say Redmi 5 is a FAILED PRODUCT. Xiaomi should call back this devices and give back my money immediately. But I think we are just ****. They will not care about it. Maybe only the service center can do something about it but it's a long and unnecessarily procedure. I think best option is to sell the phone and NEVER buy Xiaomi again and to stop recommend to anyone to buy it.

Hi! I have this exact same problem but I ruled out a hardware issue because every time there was slow to none response, if I turned the screen off and on again, it would fix it. I've been looking for a solution and after trying many, many things I've discovered the problem was that I was using the Full Screen option offered by MI, i.e. the option to remove the three main buttons at the bottom of the screen (Back, Home and running apps) and to control the phone with gestures. After going back to the classic three button style, I restarted the phone just in case and I haven't had any more response issues in two days, I think it was a success!!
I also faced this problem for months, specially, after I changed my display as I accidentally dropped my phone a few months ago. Sometimes the screen seems to freeze temporarily, but then -
- turning off and again turning on screen
- swiping the screen (bottom-top) with a little pressure for 1-2 seconds
- slightly bending the device
Any of this three work for me.
What I think:
It's a hardware (display) issue. My newly changed display creates this. But I am quite sure, when my device bends slightly this problem occurs.
Has anyone else faced with the issue of display not working properly in K20 Pro?
I started facing few problems from day 1, though the problems were minor like
.
[Problem 1] When using the phone with dark mode on or with absolute black background with 0-25% brightness the screen didnt respond well to on screen movements. Like when scrolling, the items on the screen produced a blue shadow on black backgrounds.
I thought this was due to Xiaomi's usage of cheap & low quality Super Amoled displays. Im not sure if it is as i thought it is or due to some other reasons.
[Problem 2] after 25-27 days of usage the ambient disolay started to switch of automatically after a few seconds of locking the screen. And when i tries to unlock the screen by fingerprint, te scanner didnt work. I had to push the lock button and then the screen switched on after 4-5 seconds of pressing the button(i was pressing the button only once and not holding it).
I still dont know why did this happen (I'll update soon)
[Problem 3] after 2-3 days of the problem 2 one fine morning my screen went dark.... Like completely blank, although i tried switching on and off multiple times but the screen didnt show a single hope to turn on.
So i took iit to the service centre and found out that there were many people with the same problem. Most of them being the first launch sale buyers(including me).
SERVICE CRNTRE told me that there was instructions from the comoany(Xiaomi) to collect all the Faulty screen K20 Pro's and provide a new sealed box within 1 week. Providing that there are no signs of external damage to the handset. Peoole will have to suubmit the box and its contents with the phone.
So Yaaay! For that but Naaay! For xiaomi for producing soo many faulty handsets out of the factory.
I'm writing this post as there are no posts regarding this issue on the internet and i was shocked when my phone went dark.
i’m facing problem 1 too
but no touch issue or burning for me
mine is China 6/128gb variant

Hello XDA.
The screen on my LG G3 Verizon (vs985) has been acting weird and I really would like a second opinion about if I have a screen issue on my hands or if it is a motherboard problem. I included pictures below.
Screen responds to double-tap-to-wake, and buttons still work. I'm able to turn phone off by pressing power button (as long as it normally takes to display Power Menu), then tapping on where the Switch Off button ought to have been displayed. Apparently, motherboard sends stuff to screen, but screen unable to visibly display it.
I've been using motherboard since it was bought new 6 months ago so I really doubt it's the motherboard, but I could be wrong. Screen is over 4 years old. The best way would have been to try another trusted motherboard (if screen is still not normal, then it's DEFINITELY screen's fault). So in the absence of such a conclusive test, I would appreciate opinions.
Thanks.
Pictures (L-R): When booting (picture taken with flash), when booting (picture taken without flash), after booting into Android, phone charging with screen switched off.
SOLUTION: It turned out to be a screen problem (screen was replaced and voila!).
