No it is a screen or maybe a device issue. I run nothing but stock as I have yet to get XenonHD to boot on the h631 for some unfreakin known reason to me. Anyway I have not got any issue with the screen like Blu8 mentioned. But what you are talking about I have experienced on a daily bases. I noticed it as soon as I got my h631. I think it is do with bad design of the area around the edge of the screen. It picks up touches from the edges of the screen when the skin on your fingures barely touches the edges. After I got a case that has slightly raised edges on it that sets higher than the screen it helped a lot. But I still get phantom touches periotically while I am holding the phone. I tested this theory by going into Settings/Developer Options and enabled show touches. And it shows the touches around the edges while I am holding it without the case.
