its kinda hard to explain but on my tablet its harder to turn the view and turn the camera to look at things..
i have split controls on
lefty off
sensitivity about the middle
invert y axis off
swap jump and sneak off
auto jump on
button size about middle
and the rest idk if it is connected to the problem..so i wont say...
also it is harder to turn the camera angle like i said and when it is in the split controls off it is easier..also in 0.13.1 i has no problems like this.. and i see other youtubers playing 0.14.0 b2 or b1 with the same thing i have on and it works for them..so im guessing its a device thing
