Hey everyone, i have a similar problem, and i am not sure if it is the fault of the silver pin. I had problems with my lockscreen and a bug if you flip the keyboard. (link below)
I now used the fix (i hope i did that right) and the problem with the lock ring disappeared but there is still a problem with the keyboard input. The whole Display works, i tested that in a paintprogram. Furthermore i updated the Firmware and reinstalled my custom rom. The problems occured 2-4 weeks after i got my Sensation.
Hope you can help me, this drives me crazy when trying to write a sms... youtube .com/watch?v=MkCKKhRp4Vs (you have to delete the space. Since i dont have 8 posts, i am not able to post a link... :-/ )
