I've had my coolpad quattro 4G since the last half of September. All was fine up till recently when the weather started getting colder. Almost all the time when I type or scroll through pages, my touchscreen becomes non-responsive. And it seems to take a hour or so for it to become responsive again. I can still click on apps and such,but, I have to keep tapping the screen until it registers my finger touching the screen. Can anyone please give me some ideas on fixing this?
