I have a Prestigio 3400 Duo and I have two issues with my touchscreen, the multitouch function in particular. My phone is freshly factory reset, done while trying to solve this problem, and
The first problem is pretty apparent, when I'm holding two fingers on the screen in a horizontal line it registers only one point at the center of the two I'm actually pressing (that's what a multitouch test app sees, at least). This happens exclusively in an horizontal line.
The second problem I have is when I'm holding two fingers on the screen and I let one go, the other one - the one that's still holding - is not getting registered for an instant before appearing again. So when, say, I'm playing a game on the phone and my character walks and I press a button at the same time, the character stops for a second. Really annoying stuff.
Is there any solution for either of these? I saw some fix for other phones but they're exclusively for those, not mine.
