Cant Answer or End calls. Freezing or hangs.
Hello guys, my first post here and new to the droid world so please bare with me.
I just purchased a used HTC one that was locked to AT&T and unlocked it with a code to use on T-Mobile.
I found out when attempting to answer a call, there is no response, so I keep tapping until finally it answers. During the call, I cant turn on the speaker and if I do finally get it to work, it takes several taps to go back to normal mode, and sometimes it wont.
When ending the call its the same thing, I cant end the call.
Heres the kicker, this issue is only if I receive the call while Im already inside the phone. if I answer the call from the lock screen, then I dont have any of these issues, and can end normally.
Called HTC and they never seen such thing and are interested in the phone. I have no time to ship it to them to install a new Rom or for their developers to find out whats causing this.
What do you recommend I do here? I reset to factory more then 7x, unchecked fast boot. What you think is causing this? I thought maybe that Iam using a Tmobile sim on an AT&T phone is causing some conflict as the phone is filled with AT&T apps.
I would like to avoid rooting or anything that would prevent HTC from helping me in the future in the event I need to submit this phone to them.
I found this thread and it has no solution, even after a MB replaced, but this was a sensation and 2 years ago, so Im hopping there is now a fix.
Any help is appreciated.
Called the HTC phone from another phone, and after hanging up , the HTC ( with issues) just remained on the 'Answer or decline screen', froze for 5 minutes. Then got this message "Activity phone isnt responding. Do you want to close it?"
All the process showing up in developers options, during this freeze.
Another shot has plus the above on and off
