You can get the same amount of blocks you have. You do that by placing blocks in the chest then place the blocks on the ground. Then you exit out of mcpe and delete the history of mcpe. Again you enter the game and press the world you were on and you look in your chest and lets say you had 11 diamonds and you placed the blocks on the ground when you exited out. Well the same amount of blocks are in the chest! PLZZZZ FIX THAT!!!!!!!!
