Hello

I dont remember exactly when, but the scrolling in all browsers (chrome,firefox,opera,dolphin) is very choopy now... It was smoth before...
Maybe recent KitKat ? Anyone have any idea what is that? Hardware problem?
Navigating in forums is a pain, always getting undesirable click/select with choppy scrolling...

Thanks

U can try to flash the official images via fastboot. Have u tried doing that?

Here's a guide that should be relevant

You wouldn't happen to have a cracked screen would you? There's a chance that there is a problem with your digitizer. The digitizer is what is responsible for registering touch events/input on the screen. One way to check if its the digitizer is to download an app that's similar to Paint on windows. For an old phone of mine I used an App called Sketch Artist..or something of the sort.
While making the drawing drag your finger along the screen in every direction, try to color in the whole screen. If there is anywhere on the screen that isn't responding to touch input then that is the part of the screen that may be perpetually derped.

It should be noted that you don't necessarily have to drop your device in order to have a derped digitizer, sometimes its just something that develops over time.
