Some hardware buttons won't work!

This is my first post and I must say that this is a great group of people who know what they are talking about!
Anyways, I have had my 8525 for about two weeks and I am loving it. For whatever reason some of my buttons do not work! The dpad works but the two soft buttons, the start button, ok button, email, PIE, and the green and red buttons don't work. The power, scroller, comm manager, the left ok button and the PTT all DO work. I did a hard reset hoping that would fix it but no luck. I been installing and trying a lot of programs but I thought after the hard reset that any program that screwed this up would be gone. Please help I love this phone and really don't want to take it back.
Thanks,
Dan
I took it back and that solved all of my problems.
you took back , what?

My hermes has a similar problem, buttons under the screen sometimes won't work, but if I turn off backlight and turn on, it works... but not very well because if I press green button then red button continually, buttons don't work again after few pressions....
I have changed my ROM but it's the same, it isn't a hardware problem because if I turn the scroll it works again...
This problem is known?
Thank you very muche for your help and sorry for my bad english.
same issue with my TyTN...
Same issue here with Tytn, buttons won't work but if I use scroll button a bit then buttons work again.
Hey guys,
Exactly the same problem here and it's infuriating when I'm trying to make calls on the run and sometimes I can't even pick up calls.
I have an I-mate Jasjam ROM 1.31.305.2.
If anyone has any fixes or solutions that would be great. Or do I have to send it in for repair or something?
So has anyone managed to fix this? Anyone tried a hard reset?
I have no idea how to diagnose the issue and even whether it's a software or hardware fault.
Jasjam- Same here
Also my screen turnes white some times

I'm also having these problems with the front buttons not working. Very frustrating. The problems seem to be platform independent.
I really cannot believe this. When I used the search function I noticed so many people are having these problems with the TyTN, and no resolve.
It's my second machine I received from HTC, first one also had these problems.
HTC sucks BIGTIME.

My phone screen does not turn off

Does anyone try before that the screen wont turn off?
I didn't install anything new in these 2 days, but the screen started on all the time.
I need to press the on/off to turn it off manually.
( I dont have the always on setting on, and no matter I changed the timeout to 15s, or 1min, it wont work)
My gf's one had the same issue before, but we dont know how but it fixed.
Looks like a random bug
It is so annoying that if I had notification at night, it keeps on for the whole night!!
Anyone has/had the same problem?
My wife's phone is having the same issue, but since she doesn't want me to check .. I just kinda left it alone.

...and screen can only be used with the pen? This is a problem i have.
Just switching ist off and on fixes the problem (i have not to reboot).
Seems to be a software problem.
No the screen works well its only the buttons
Absolutely no problems to report with mine???
Yes I am having this same problem as the poster described (back and menu buttons switch off)
Specifically happens after a phone call
Happens to my brothers phone as well and both phones are sourced from different suppliers
Think a software update may fix this? or should i send it back and buy another one?
Thanks
Pretty widespread problem it seems:

I tend to believe it's software-based though

Screen Freeze

Hello, I am experiencing a new problem since the 2 last updates ( last one was 12.1-YOG4PAS3AJ ) as the screen freezes randomly. Mostly when receiving a call which is very annoying as you cannot answer. So I have to reboot the phone 3 to 4 times a day. I am now thinking about switching to ZUI as I use the phone as my daily driver.
Anyone experiencing a similar case?
i encounter this when you change adaptive brightness.
Ok thanks, I put it to automatic to see if the bug stops
Screen freeze
I just bought this phone yesterday and I also have same update and the screen goes off and comes on while taking calls and ending calls.
Any solution for this problem? I face this problem even when i turned off adaptive brightness
@Glops4 Do you find a solution for the problem?

I just did as you suggested, it is now working fine. I guess the bug still exists.
i have the same problem :'( ,, sometimes phone doesnt wake up from sleep , and sometimes after a call the touch stops working but buttons work .
Any solution or work around? Did you use any short key for long press of home/back button? I felt whenever i use lock screen as a option when i long press home/back button, i am hitting this issue. Please confirm @hwoarang626 & @Glops4.
I tried the long press home for screen off.. But i dont encounter tbe issue... I only get it some times after a call
My system details
Mine was doing the same thing, I am up to 12.1-YOG4PAS3OH, that update solved the problem.
Edit: hwoarang626 looks like you are still having the problem?
it happened 2wice then i enabled adaptive brightness and stopped using double tap 2 wake and it didnt happen again .
After last update I cant use fingerprints capasitive button as back button. I couldnt find any settings. Please help me. Thanks
I have left the buttons default, and do not use the 2 tap to wake screen.
The settings I use are Adaptative Brightness on and LiveDisplay off. Never had a screen freeze since.
And long press back button didn't help either.
