It seems that the latest updates to Minecraft for Android have caused the touch screen to be uncalibrated, with a lot of latency, and the sensitivity seems to be a little "glitchy". This makes the game difficult by creating touch inconsistency and causing some in-game deaths.

I don't know what version or update this issue started on, but it seems to have been after the month of March.

My device is a Motorola Moto G5s Plus, with 3GB of RAM and Snapdragon 625
