[Q] any solution to Power button sensetivity?

Hi,
Did u feel in your's phone that the power buttom working twice in one click??
Its make me crazy !!!
I checked in "key test" and when i click on the power buttom it's send dubble command
What can i do?
I have this problem as well. The best solution I've found is using CM7 -- there's an option to wake the device with the volume rocker, and it works much easier.
Good luck.
just started noticing this issue on my phone recently - extremely annoying. i wonder if it's the button going bad or if it's the switch itself going bad and getting caught in some kind of weird angle upon release?
HTC said that it is a hardware issue, and why do we need more threads like this? I am sure there have been at least 2.
Hi everyone, just registered here as am having a few pretty big annoyances with my Sensation.
Just wanted to chip in with my experiences of back-button issues; I've already had to send one Sensation back because the button's microswitch went faulty (was stuck on) and it looks like this is a weak link with this hardware.
Has anyone else had the power switch fail on them completely?

Can you do it? I have this problem too. My Nexus S automatically turns on when I put the battery in.

Xperia Z3 D6633 Touchscreen does not work

With less than 24 hours of use, the touchscreen on my brand new Xperia Z3 Dual (D6633) stopped working. The phone was activated on the T-mobile network (but was not bought at T-mobile because they do not sell the Dual SIM version). The phone has NOT been immersed in water or abused in any way. I was able to power down by holding the Power button and Volume Up buttons. Sony Support said to try and repair the software with PC Companion. That did not work. Sony said I could send it in "for evaluation", but that might take 14 days just to find out what is wrong.
At this point, when I power up I am in the language selection screen and can not continue because I can not select "Done" on the touch screen.
It was suggested that if I boot up holding the Power and Volume Down keys, I would enter "Recovery Mode" and the Volume control could then be used to move up and down on the screen to make selections. However, I enter "Safe Mode" and the Volume control seems to just control the volume (at least there is a volume control slide graphic that seems to indicate the level of volume).
Any thoughts as to how to fix this or is this simply a bad unit that should be replaced with a new working unit?
Thanks in advance for any help you can give me.
Better use warranty to get a new one.
What failed -- digitizer or electronics controlling digitizer?

I think I might have to go through the lengthy process of a warranty return though I was hoping there would be a quicker fix.
Does anybody know what could have caused this? How do I know if it is the digitizer or if it is the electronics that controls the digitizer?

I have similar trouble with Xperia Z3 Dual Sim , TouchScreen frequently stop responding for about 2-3 second , after that it will be ok,it happens 4-5 times from yesterday that I bought my new Xperia Z3 Dual and it's really annoying.
It seems Sony sucks on Xperia Z3 TouchScreens.

Black screen with no response

Hello everyone,
i got a strange "bug", i don't use my phone 3 hours and when i press the power button nothing appends... I plug it in the charger and the charging led don't switch on... To restart the phone i have to plug it in and press the volume down and power button for a while.
When the phone woke up my battery have drop from 70% to 20%.
Did someone got the same bug ? Or it's a material faillure ? (my firmware are .185)
I kind of have the same (similar) issue on CM 13.0., i have submitted it as a bug and so did two more people. The Z5 CM Devs are trying to figure it out so i reckon you might be able to find what you need there. You might not find it straight away because there is no solution yet, but soon.

Right, it's seem to be the same issue on CM13. Realy strange because it is not base on sony firmware.
