[Q] Z1 power button problem

Hi
Iv had my Xperia x1 about a year now. The phone works fine. The only issues I've had are that the speaker grill on the bottom and the silver ring around the power button fell off. However these were not major problems for me as I don't use the waterproof features of the phone so I've left them as is.
However today my power button has been playing up. If I touch the button, without pressing it, the button acts as if it's been pressed and locks the phone. If I keep my finger on it the phone turns on. The button works fine while pressing it too and the phone is working perfectly fine aswell. It's just this touchscreen button issue. Iv Googled it and most power button problems for the z1 seem to be related to it not working etc however mine works fine.. It works too well actually.
I was thinking maybe the part is loose and needs replacing.
Would replacing the power button fix this and does anybody have any idea what's going on /what I should do?
Thanks

Help with lifeless z1!

Hey guys,
Over a year ago the screen on my Z1 broke. It wasn't until two weeks ago that finally bought a new screen. The phone has been powered off for over a year. Once I installed the new screen and tried to power it back on I got no response. Just a constant red light led. I have left it charging over night on a number of occasions and nothing! Holding down the power button does nothing, holding the power + volume makes the red light flash twice, with no vibrations.
Any advice on what I should do would be much appreciated!

P20 Pro Power Button Stuck = Constant Reboots

Hi All,
A few days ago the power button on my P20 Pro started to become faulty (running android 9.1.0.372). The button itself still clicks and does not appear to be stuck. However when it is pressed it does not lock the phone, instead after a few seconds it brings up the restart / power off option and then automatically resets (I assume due to the phone thinking that the power button has been held down for 10 seconds). When the phone then restarts, it is 50/50 whether it automatically starts the 10 second reset timer again, or if it will let me into the phone for a few seconds before triggering the restart again.
In attempts to troubleshoot, I downloaded a button teester app, but it did not register the power button when I pressed it in. I have since managed to factory reset the phone, booted in safe mode etc betwee the random restarts but none of these have solved the problem. I've looked on the forum / Google and can't find any mention of this issue for any other user. It looks like a hardware issue to me and to get the button replaced is £200...
Any Ideas? Thanks

When it feels like a hardware issue and acts like a hardware issue - it's a hardware issue.

I feared as much, I have ordered some replacement parts to see if it is fixable
For anyone picking up this thread with a similar issue...
I fixed this a few days ago, ordered a new power flex cable (£2) and battery (£20). Heating the phone to soften the adhesive was a nervous moment, and the inside of my P20 pro was different to the instructions I followed online... After removing the motherboard and through a bit of guesswork, I managed to unstick the old power cable and the metal casing that sits between it and the physical buttons. When reinstalling the new cable, I popped the power and volume buttons out to ensure the correct alignment of the casing and the cable.
The old battery was really stuck to the phone and took a lot of pressure to lever out. Overall, managed to install the two new parts and for good measure, android 10 got pushed to the phone the day after! So it feels like a brand new phone now

Nex 3 volume down button problem

Hi guys!
All was fine for a long time after i bought this phone, but sometime ago instantly (it happened when i went sleeping and after i waked up, i saw that the button became a little "stronger", and it made impossible to take a screenshot using the stundart vol buttons and a power key) the sensor zone of volume down button rised and became really stronger. I didn't drop the phone, or didn't hit him, so i thought "okay, it's just a bug, just a temporary lag".
So I had it till tomorrow's morning. I just waked up and saw, that the button doesn't working now. It's not pressing. The volume UP and power key still are working good. I didn't drop my phone this night, so i still think that it's just a bug.
Someone had this problem? What i
can do? How i can check that it's really program lag?
It started after i installed this official update
PD1923_F_EX_A_6.17.3
