Having had the HTC Sensation in-hand for about a week, our unit has developed some troubling issues with its touchscreen. Namely, the panel often misses first presses, and also struggles with fast brushing movements.
The first issue results in great frustration when typing, as auto-correction of words does not work without the first letter. It also means you often have to tap several times on icons on the homescreen to launch an application.
With the second problem, the malfunctioning results in very choppy scrolling, in the app drawer or in Twitter applications such as TweetDeck. Frequently the touchscreen will register a brushing touch as a press, and will select whatever your finger happened to be passing over at the time. This leads to unwanted opening of applications when scrolling through your app drawer. The touchscreen's aberrant behaviour also makes it very difficult to unlock the touchscreen in a swift, natural motion. The unlocking gesture must be done very slowly and deliberately to avoid failure.
As you can see in the video above, the issue is sporadic in that it can come and go. Restarting the phone sometimes fixes the problem but it will always come back eventually.
So, we'd like to know if any of the other new Sensation owners out there experiencing this issue, or is ours just a funky unit?
