CHUWI HI10X N4100 has keyboard button issues. The Down Arrow key always looks like it’s being pressed on its own, causing the page to keep scrolling down. The Backspace key doesn’t work properly, sometimes it doesn’t respond at all. The Enter key also works only occasionally. Because of this, I always have to use an external keyboard. What should I do?
Come on, friend, search on YouTube how to clean the keyboard, as a first step.
