I bought a Mi Pad 4 a while back. Honestly it has no other problems, but for gaming it has a huge one: **Namely, “touch dropouts.” Actually, this kind of touch dropout is an old issue with Xiaomi and the like. Lots of people have talked about it — from the Mi Mix 2s to the Redmi Note 5, it’s everywhere. Many say the problem is that Xiaomi’s touch ICs just aren’t good, and the Mi Pad 4 being a low-end product certainly wouldn’t use any fancy touch IC. So not long after buying this tablet, after playing some Honor of Kings on it for a while, I noticed the screen touch started jumping around, and sometimes it would just randomly cut out… or stop responding. At first I concluded the root cause was: Because the touch chip is cheap, after the machine runs for a while and heats up, the touch goes haywire.
