Put something in the chest. Close it.

Take the item out and close the chest again.

Walk around and count to 15 (it doesn't work if you count to less than 15 for some reason).

Go to the home menu.

Double-press the menu button and a hot bar should come up with loads of apps on. Hold the MCPE button down and click the erase button in the top-left corner when it appears.

Go back onto MCPE. There should be one of the items in the chest and one in your inventory, or double however many you originally put in the chest.
