I recently got a new trackball and ring and OEM dome sticker to replace, so I just did all of that, and UGH...
So my trackball works, it scrolls around just fine, but when I press down, it doesn't open things. Like if I push down on messages or something it doesn't open up my messages. It does click though.
The dome sticker wouldn't stick, so I used some double sided tape to help it stay in place. Maybe that's the problem.
To open applications I have to use that little arrow key. I guess it's not the end of the world, but WHAT IS WRONG WITH MY PHONE.
Time to get another trackball dome. By using the double-stick tape you've changed the operating parameters of a vital piece of the puzzle. It doesn't take much to make that piece inoperable.
