Half of display not responding to touch - Xperia Z3 Q&A, Help & Troubleshooting

Hello, yesterday my z3 felt on floor. Display is not broken,but from half of it to the top is not responding to touch. Everything else is fine, colors, video play etc.... Is anyone had problem like this? Do I need to change the whole display or it is just something "unhooked" under it? Thanks

HTC Touch HD, problem with the display

Hey whats up,
I've got my HD for about a half a year and recently I noticed that its display doesn't display stuff properly. When I display some color transition, it's just not smooth. I'd describe it more like 3mm thick lines of cumulatively dark color next to each other. Therefore, the transition works, in the end the stripes make the picture look like some sort of a transition.
My problem is, that the final picture looks like a crappy GIF image. I'd like to ask you other guys with HTCs, is it normal that the display shows things this bad?
I can't remember if it had been like that before I bought it. I believe it might have something to do with one incident where I tried to take a photo while shaking the phone, resulting in an automatic soft reset leaving the display damaged for some reason. What do you guys think?
Thanks
Maybe another Softreset could help.
If not try a Hardreset.
regards

Are you setting this picture as the wallpaper, is this what u mean?
Im not sure what u are trying to do, is it only this picture that looks crap?
Did you solved problem with your HD display?
I have same problem with my Touch Cruise. But, not always, only sometimes. Clicking power-on button multiple times helps in temporary problem solving, but it repeats again and again.
i feel u can not care

HTC ONE M7 Display Fault

I've searched but can't find my problem anywhere so I'm hoping someone can help.
The phone was my daughters and had a cracked screen, the phone still functioned and had no other faults.
I've fitted a complete shell including screen and everything was fine for a couple of days then the problem started. When I have a brightly coloured background the titles under the screen icons distorts, the brighter colour the more the screen distorts and shimmers. If I change to a dark coloured or B&W background everything stabilises again. It might be a coincidence but about the same time as the fault started the phone did and update to 5.0.2 from 4.x.x. The rest of the phone works ok unless a bright colourful image is on screen. I've tried all the obvious suggested tests, reducing brightness etc but nothing makes a difference. Any help is much appreciated.
I've tried to attach a photo but it crashes safari on my iPad.
When looking at the HTC wallpapers the problem is worse if I scroll down the choices it is worse on the centre and right images which I think are rain and grass, 2nd row from last/bottom, the dandelion is ok though. Would this be the screen itself, software or hardware?
I really like this phone but will probably have to go back to using my old iPhone if this is android.

Replaced screen, now it flickers and tears

Hello. Basically my phone fell out of my backpack and had to have its screen replaced. Everything went smoothly, the screen works, it's just that sometimes it flickers and I cannot understand what is causing it. It happens on some album covers, when i drop the notification bar, or when viewing photos and such. The video: https://www.youtube.com/watch?v=hFp2pkGPo5k Is this something that can be fixed or am I royally screwed? Thanks.

Touch screen sensitivity

Hello. I have an Nvidia Shield tablet k1 on lollipop 5.1.1. Everything is great about this tablet except the touch screen. It is really sensitive. Also, when I am scrolling, it "jumps" and goes faster than I actually scrolled. It scrolls faster than it should. I found this thread on xda. It helped a little with the being too sensitive issue, but scrolling is still really weird. This is my second device since the first one's micro sd card was defective. They both are like this. Is there anything I can do, or do I just have to deal with it?

I was opening a thread with this exact same issue. I'm not on stock though (using the latest CM12 nightly), so I don't seem to have the 'Sensor Calibration' option.
Also the touchscreen seems to register a touch even when the finger is not touching the screen.
On the other hand, if I scroll a very small distance (like 0.5 centimetres) the list I'm scrolling doesn't move at all. This doesn't happen on other devices such as my Nexus 5 and Nexus 7 and is very annoying in some cases (some games, or moving the cursor for keyboard input).
I'll try to record a video of this behaviour.
What can we do to fix this?
Update: found a video (not mine) showing the issue I'm talking about: https://www.youtube.com/watch?v=08uPtusOJHQ
anyone else with this issue?
I also have this issue on/off sporadically on stock rom.
I'll be scrolling and itll jump back the opposite direction
Its like it looses track of the touch then catches it again.
It's irritating as my S5, Nexus 2012 have no problems scrolling smoothly.
I don't recall the original shield i tested in store to have this issue either.
Currently having amazon ship me a replacement to see if its just limited to the one I received. (QA issues)
Calibrating screen might fix the issues: go to About in settings and tap on model number until the calibration screen comes up. then hit calibrate. don't touch the screen then when it asks to reboot, reboot.

Click to expand...
Click to collapse
Did it fix the issue I posted the video about? I'm on Cyanogenmod now so I don't have the option to calibrate the screen, but I would consider going back to stock if it fixed this issue...
Calibration doesnt help at all , same issue at brand new k1. Nvidia says thats normal functionality lol
Yeah, very normal for a gaming tablet which would require precision...
Not trying to take up for this thing but I haven't had the first touch screen issue with it . so maybe not all is affected?? I've tried to replicate the issue but just can't everywhere I touch and slide is smooth
You mean it doesn't "jump" like the OP said? I don't seem to have that issue either.
I'm more concerned about the touchscreen's precision, as shown in the video.

Big problem with display

Please help. I think my GPU is failing. I have green dots when I turn the phone on, then screen is always shaking, moving upwards and the colours are not displayed correctly. See photos here: imgur[dot]com/a/aMDz0 . The problem with the colours appeared before in the last 2 weeks but I always fixed it by rebooting. Since this morning, it became much worse.
I made a screencast but on the video file everything is displayed perfectly.
Please tell me what seems to be the problem and what solution might I find to solve it. The phone is almost unusable now.
