ipega 9076 Right analog stick bugging out

I also have a problem with this controller. It turns off on its own even tho it's fullly charged. Another problem is when I'm playing a game either minecraft bedrock edition or other android games that is controller supported, whenever I try to fully move the right analog stick left and right it would turn right then stop ro stutter, then there's moments it would turn to the opposite direction. I don't know what caused this.
