Is anyone else having problems with the keyboard? For some reason, I cannot get the letter "n" to work unless I'm typing a text message and the screen is rotated.
I'm having the exact same issues...only I've done a bit more testing and found that the entire horizontal row of the screen at that area (roughly the entire third row of character keys on the portrait keyboard) becomes "dead." This deadzone is physically static, so that when you rotate the phone to landscape, the problem affects the keys on the landscape keyboard that are in that area (o, partially k and m, and the "12#" key). I went a bit further and got a Paint type app to check, and as you scroll your finger with the brush down the screen, you'll see that the deadzone is affected there as well, and will either stop drawing at the edge of the deadzone or "jump" straight down if you finger past the deadzone. You can see a similar type behavior when dragging to scroll, as a little "stutter" or "hop" will occur every time you finger over the dead area. So the malfunction is actually affecting all input, not just the software keyboard.
My problem is sporadic over long times...so it will malfunction for hours at a time, then suddenly remediate itself for a few more hours, only to come back again. I haven't been able to link it to an application or a process yet. Reboots don't always remediate the problem, so I can't rely on that. The person that mentioned a recalibration of the keyboard - good suggestion. This will make the keyboard useable, with a bit imperfect touch mapping, but will allow you to use the phone despite the dead area.
This isn't fun though, especially since I'm coming from an iPhone, whose stengths included a great touch keyboard. If anyone has any hints or tips as to what might be the root cause (application, background service, hardware quirk I'm not familiar with, etc) I'd really appreciate it. I'm just glad I'm not the only one, because it seems that every time I try to return the phone, it behaves perfectly for the rep :-/
