On my HTC Thunderbolt, when I type the same character twice, it seems like there is a lag. The response time is off compared to my iPhone 4G. On my iphone, the only touchscreen that I used up until the Thunderbolt, you can quickly type without worrying about your keystroke not being read by the phone has having striked twice.
I am interested to see if others have had a similar experience with their Android phones--being a little slow on the key repeat issue. Would this be something particular to a settings or just a UI convention?
