I can't move in minecraft mobile

I play on my phone, and when i am using the new costumized controls, sometimes, the game just suddently stop allowing me to move while i am moving my camera, suddently i can't move and look around at the same time. This bug only happens after a few minutes of playing, and the only way to solve it, is by closing the app and oppening it again. At first i tought this was a problem with my phone, but after playing on other mobile devices, i noticed the same bug again
