Display issue's, please help! - Xperia Z2 Q&A, Help & Troubleshooting

My beloved Xperia Z2's screen has some serious problems. Funny lines appear on the display, making the screen unclear and hard to read (see pictures attached).
The weird thing is that when the screen has been off for 30 seconds or more the display is fine again, for about a second, then back to fuzziness...
I have done a factory reset with no love, of anyone has any ideas or suggestions on how to fix, I would be forever thankful

If it doesnt show up when you screenshot, then its hardware
If this problem was firmware/software your systemUI or surfaceflinger would crash, if not it would show in the screenshots
And also it wouldnt show in the fota kernel or kernel boot process

Screen not turning off while on call

Hi;
I'm using my Z Ultra for just a few days.
I have upgraded to. 510 firmware.
I realized that my screen does not turn off while I'm on call.
Anyone facing the same issue? Is it a firmware problem or do I have a hardware problem with proximity sensor?

Definitely a software problem. I've had proximity problems on my Note countless times, and a reboot has fixed it almost every time. Reboot and see if that fixes it.

Home button problem?

Every time I press the home button it brings up the recent apps/task manager multitasker window. I click it once for a split second and it brings it up like it would if I held it down for five seconds. This has been happening for about a month now and I have no idea why. Plus I notice that when I turn off the screen it lags for a second too. I'm on build MJ7 and I'm rooted. Yes I have tried turning the phone off and clearing the memory, along with setting processes to the lowest amount but nothing works. Does anyone know what it is or how to fix it? Thanks.

Nespresso logo in notification bar

I have a fancy letter N like the Nespresso logo permanently in my notification bar. Presumably it's from some app that's running. Does anyone recognise the app?
Sent from my D6503 using XDA Free mobile app
Nespresso :laugh:
Don't worry man, it just means NFC is active
I don't remember if NFC is turned on by default out of the box or not but when you do hard reset, it will be on. You can just turn it off as rep.1 said.
Nespresso, what else

I'll turn it off. Thanks for for the replies.

Something similar happened to my sisters g3 two days ago. She pulled down the notification but it only came half way and the phone froze. A battery pull was the only way to fix it, thankfully it hasn't happened since.

Thanks for your help. I think when I put this otter box symmetry on I had some dust or something messing it up. I took it off and it immediately started working. Blew the case out with duster and now I'm good.

That's interesting. My sister doesn't have a case yet so I guess her issue must be different. Btw if it happens again enable developer mode and show touches, maybe your case is causing ghost touches.

Only freeze up I've had was when i was using the camera. Took some pics, recorded a video, took some more pics, exited camera app, phone froze up and i had to pull the battery. I've tried to reproduce it but can't.

So far up to date everything is smooth as silk on this bad boy. Just that stupid feedback when the head jack is plugged in and I can here feedback when I press certain areas our buttons.

Good thinking on the developer options. That might come in handy if I need to take it back to best buy. I've got the headphones Jack issues plugging it into my car stereo as well. Software can fix that so no big deal.
