The touchscreen on my N9 has become intermittently unresponsive. It is fine most of the time, but sometimes stops responding to touch all together, or responds in a very jerky and 'gappy' way. Sometimes on starting up it accepts no touch input (for the unlock code) and I have to restart the phone. I have also noticed that the Swype keyboard trace (the line you draw between letters) has more 'jaggies' than before, and occasionally has gaps. This has made typing more difficult when this behaviour is manifested, about 10-15% of the time. It stopped me writing this thread on the N9 - I had to turn to my trusty N900. Has anyone else seen this issue?
