I recently dropped my Xperia Z2, the LCD and the Touchscreen both were dead. Therefor I bought a original LCD+Touch Replacement which was shipped to me a few days ago from the UK. I installed the new part, the lcd seems to work but my the touchscreen module doesn`t work proberly. It doesn`t recognise my fingers on the right spots, often doesn`t recognise any touches! then I have to reboot or turn of the display and then turn it on again. writing nearly is impossible, sometimes I have to press very very hard on the screen, sometimes my phone types things like "ladgnlaerhjnjhgdihhdgzghgzgzgzzgzgzgzgzgzgub" without me touching the screen. it also manages to unlock itself with when I use the swipe gesture for the lockscreen. is the touchscreen broken or is it the my rooted android 6.0.1 with xposed + twrp recovery?

Hello all, my capacitive buttons on evo 3d are broken (some day they just stop responding) , so i googled for solution, find nothing, then i ordered new digitizer, now digitizer is waiting for me to have money to repair my phone. But some days ago ill installed CM10 With sweep2wake option. When my phone is screen off, when i touch the home button (thats is not working) guess what. IT LIGHTS THE PHONE AND RECOGNIZE TOUCH. While i sweep from home to search - my phone unlock (So my buttons recognize touch) I am now like wtf? Is there a way to examine those buttons with some sort of programs or etc? Is there a way of repairing them without changing digitizer?
Best regards, Bazyl93

So the buttons only work for sleep to unlock or do they work like they should on the cm10 rom? If they do not work normally then it may be the s2w recognizes the area of the screen close to the buttons, but not the actual buttons.
Get kernel tuner and then go on to check with the brightness of capacitive buttons. There is a chance you have them at 1% and you can't make out if they are lit or not ...
Hi everyone. After changing the usb pin of my phone, the touch screen started doing some weirds things. Sliding among desktops is rather laggy. Pressing an icon is not enough to get the app (or whatever) to work, a second attemp is neccesary in any other part of the screen in order to make it happen. The physical buttons seems to be working fine so far.
In further investigations it seems like pressing on the screen is well detected, since i can press an icon and move it around a desktop. But unpressing anything goes undetected.
I see no physical damage on the screen or the flex that connects it to the motherboard. This is not an issue related to any especific rom or kernel since i tried with a couple of them before getting to this point. Is there any app that allows me to monitor what part of the screen is being touch?
Can this be resolved by a firmware update of any kind of just a hardware replacement?
Cheers
I have updated my Z2 to Lollipop few months ago. I found out that after 2 weeks, the left keypad could not be used, I could not press on "1", "Q". Now I have to one-hand keypad.
Yesterday, another issue happened. The android buttons are not responsive, the "back", "home" and "multitask" button do not react to me at all. I have to make the screen landscape if I need to use those buttons.
But when I am on lock screen, the "call", "unlock" and "camera" button is responsive. I did factory reset and wipe cache but still not helping. I asked some friends but most people say that it's the digitizer problem because none of them experience these before. I am not sure about this, but there are no dead pixels, no dropping at all. The age of the phone is 1 year. Everything was fine when I am on 4.4.4, all went wrong after I updated.
What can I do to fix this?

Highly recommend using Repair Firmware to wipe phone & install fresh rom By PC Companion
you should install PC Companion & Connect your Phone to PC then w8 for app to recognize your Xperia
then click on Check Update & select Repair Firmware.
Do It & Report Result Please

same problem
me too facing same problem...
Android version: Android 5.1 (Lollipop)
Latest available software: 23.4.A.1.200
I've bought this phone around february/march 2018. I've been using an LOS 15.1 unofficial rom last updated april/june which has been working perfectly, no problem besides no VoLTE but i don't mind this.
I booted the phone into recovery (longpressing power button, then selecting with touchscreen the "reset option". It turned and then couldn't select any button via touchscreen. The phone reseted itself by the first time and got into this! Now touchscreen don't work (so i can't turn it off -it just restart when I longpress for 5 secs the power button), can't unlock it because I set it to ask me the pin on every reboot..
As a sidenote, the phone fell of my desk like 2 months ago, and changed it's entire screen tile (the LED and the glass) for another one because the original one got shattered and made the device unusable. I'm thinking it's a malfunction of this module (or maybe something disconnected? Is this possible)
Anyway, tomorrow i'm going to ask the guy who changed it for help. BUT, is there any other possible fix guys? Or a hard keys combination to completely turn it off so I don't get more messages and save battery?
Thanks a lot!
Just flash stock MIUI via adb n it will work ?
Hi everyone. I had to replace my screen due to colour fade, stripes, etc. which has been done successfully in terms of hardware replacement. However, the screen is completely dead, black, no touch effects etc. I have used a second brand new screen - same problem. All internal connections seem to be working, pressing the power button results in vibration notifications and I can get notification sounds plus a truncated boot up sound but nothing at all on the screen. I have previously rooted the phone with no problem, although I cannot remember which ROM I installed (it was rooted 2-3 years ago). I bought a new phone and have just come back to this phone in order to renovate it as a backup phone should the newer one fail. I believe looking back on my PC that I installed a modified stock ROM for rooted EU H930.
The phone registers when plugged in to my PC, adb recognises it and lists it under adb devices but I cannot get it to function or light up the screen. I think it may be a motherboard issue? Thanks
