Earlier this morning, I pulled out my phone to add something to the calendar, and I found that it had frozen. After ensuring that the power button didn't work, I pulled the battery and rebooted. It came up fine, except that the long presses on the physical keyboard have now stopped working. The SYM key also provides "\", rather than the expected behavior. The FN button in combination with keys still works, but I can't get accented characters like едц, which was working before.
I tried reflashing my current keymap, but no dice.
I tried changing the keyboard language to something else, but no dice.
Has anybody had a similar issue before, and how did you solve it?
