[SOLVED] Z5P touchscreen (tapping) issue - Xperia Z5 Premium Q&A, Help & Troubleshooting

I'm facing a weird issue with the Z5P touchscreen (tapping) action on the top left side of the screen panel, the usual location for the (back arrow <-) or the (Menu Icon).
1- after reboot everything works fine
2- after an hour or so, sliding (for example the facebook chat head) is detected over this area, but leaving it then tap to open is not detected, same happens with any application back arrow or menu icon, even the (back) of the settings for example.
3- in landscape mode the same area (the top left side) is not detected when tapping over, although the touchscreen panel location is changed now its at the top right, as i rotated the device clock wise
4- after reboot every thing works fine for an hour or so, then the issue is back.
tried the services test, the sliding touch is detected allover the screen, but at the (tap test) tap is not detected at box no# 1. this is weird for me as if there was a problem in the touch sensor, the problem should exist at the same location, even if i rotate the device, but it stays at the (back) arrow when the device rotates.
tried PCC software repair with no luck so far.
The Fix:
Facebook Messenger was the cause for this issue, by removing it the issue is gone immediately without even a reboot

Did you try disabling chat heads to see if it was only a chat heads problem? Because I have messenger installed and I don't have this problem.

thanks man, works like a charm

unfortunately, the issue occurred again even the chat heads was disabled

Just delete the facebook messenger app. Must be a bug. That's the only way I got my problem to go away.

[Q] Problems with 5.1.1

My watch was working perfectly before the 5.1.1 update, but ever since the update, it is slow to wake, unable to swipe away cards from the watch face without opening them, the touch sensitivity is TERRIBLE....have to swipe over and over to get it to register, and for notifications I am unable to select "ALL"...can only select "priority" and "none".
Is anyone else having these problems?
5.1.1 problems are being discussed here if you're not aware:

No problem in starting a new thread, though.

I noticed that the touch screen seems derpy to me too. Something is definitely weird with the toggle shade thingy. I'm having the same problem with selecting "all". You can get it, but you have to find the exact spot below and to the left and tap frantically like a dozen times. I reccomend using the test app in developer settings and open the touch test. It will display a small grid and it will trace all your touches. Don't worry if it says fail. Just notice whether or not its tracking your finger. To get it to pass you have to turn the lines green by swiping in a certain direction. Mine tracks perfectly so, for me at least, the hardware is fine. Definitely a software issue.

Yesterday I installed the Android M preview on my phone, and so I had to do a reset on my watch. Now all of the touchscreen wonkiness has gone away, and it's working fine!
Before I was unable to get the app list to appear by swiping from the right, but only by tapping once. Also, I couldn't swipe in the center of the screen in the mode selector shade, but only above or below the row of icons. Now that's all working as well.

Long press not working anymore on some parts of the screen

Hi,
The title speaks for itself.
Big issue here, long-press on the screen of my D855 doesn't work anymore.
Touchscreen is fine but long-presses just acts like a normal press.
I can't tell when exactly this bug started but it's really annoying since some actions can't be done without it (can't move icons, play specific games, etc...)
The lower end of the screen works fine tho (navigation buttons and apps dock) but everything above don't.
Some rare times it works with no particular reason.
Can someone help me with this ?
Is it hardware or software related ? (updating firmware to V21a didn't solved my issue).
Bu chance u aint got a glass protector on do you
No glass protector.
Stock Rom.
This is a really weird bug because it works 1 time after a "pinch to zoom" for exemple and then again it stops working
Off top of my head try if ure rooted xposed like g3tweakbox or gravity box one of 2 change long press behavior or or goto acseability and change touch feed back time to short
I have the same problem, whenever I scroll down/up, it goes directly at the bottom/top. Sometimes, it goes back to normal, I don't even know why but frequently it goes back to the problem. I had already gone to Accessibility, ..., set it to slow and it seems not to work. What to do? :/

Notification pulldown don't work

So i just got my phone back from service. I had a white spot on the screen. They fixed it by replacing the motherboard. It'll all fine and dandy right there. But i noticed i could not pull down the notification bar in potrait mode. While switching to landscape it works. This sounds like a hardware issue but im not sure. Is there a way to test the screen?... if a move a widget to the top of the screen from my homescreen. The screen detects it's up there.. so i guess the touch is ok?
The service took about 4 weeks so i hope i don't have to send it in again
I've tried resetting the phone (clean install)
UPDATE: Sent it back for another 4 weeks of service..
Hello
To make a touch screen test follow these steps:
1- open the phone dialer and dial this number *#*#3421#*#*
2- Choose accept, that will take you to a hardware test page
3- Choose touch screen line draw test.
Thank you
i have the same issues its software and gets fixed automatically
but there should be a solution
I just received my brand new HTC 10 today and I have the exact same problem as you.
I am unable to pull the notifications bar after I unlocked the phone in portrait mode. However I can pull the notifications bar while the phone is still locked AND when the phone is unlocked and rotated to landscape mode.
I have tried factory resetting my phone and upgrading to the latest software but the problem still persists.
What should I do?
Anyone solved this problem?

It's a screen issue. Do a line sensor test from the help app

Pull down status bar while phone on table

I have a strange problem swiping down to see the notifications while the phone is in portrait mode and it sits on a table (not in hand) - if the phone is on landscape it works fine.
If the phone is in hand everything works ok so I don't think this is a hardware problem but when the phone sits on a table and I open up an application (e.g. Facebook, Waze, etc.), I cannot swipe from status bar to see the notifications (if I am on the launcher it works because you can swipe down from anywhere to see notifications)
I am on OxygenOS rooted with Magisk and I am having Xposed installed.
Does anyone else have this problem?
EDIT: Seems like the problem is related to Display Size setting.

external screen unresponsive when notifications active

2071-3 on a12 retus fresh 100% wipe and install, have a weird issue where normally the external screen works perfectly no matter what page or activity (weather, dialing, texting, other apps in general), but when there is a notification in the tray and you try to touch or swipe or whatever to view it the screen is 100% unresponsive. you cant swipe up, down, left, right or touch the tooltip, its completely dead to touch (but displays just fine) until you open the phone and clear the notification tray. its very weird. sometimes if you swipe the screen right after turning it on you can move into another page and it works perfectly fine as normal as long as you dont try to interact with the home page, but if you go back and stay there or try to touch the noti it becomes unresponsive again.
is this a known bug? is there a fix? the only other thing i can think of is that i disabled some of the bloatware apps it came with and one of them might be responsible for the functionality? i have disabled the following, and none of them except where noted would seem like they would have any effect on this:
google assistant
astro odyssey
demo mode
device help
google duo
google files
google games
google one
google tv
moto
moto display (yes i know, i turned it back on and it didnt fix it)
moto feedback
moto notifications
youtube
yt music
