you have to tap twice to change the item in your

for example  say i have a chest in my hand and i have to switch my sword to fight a zombie i have to double tap my sword in my hotbar but by then im already half health. it does the same thing where i have to double tap even when i am at the home screen even when i go to create a world, it is so stupid i have died about 5 times because of that bug i hate it i think it should be fixed immediately!!! =< =< =< =< =<
