Touchscreen Sensitivity always resets even it is customized by the player

When you play the latest version of minecraft, (0.16.0) maybe you want to customize your own sensitivity on your touchscreen.You've made it and until you played it again. But the sensitivity turns backs to normal! (0.30 Sensitivity) Then you go to the settings and then you see that it is on your customized Sensitivity!

Please fix it. I also experience this bug.
