Hand must be empty to open door or chest

Galaxy Tab A with S pen
If all inventory slots were full I could not open a wooden door. When I tried to put an item into a chest so I could have an empty hand, chest would not open either. If I threw an item I could open the chest and then move next to the item to pick it up and put it in the chest to get an empty inventory slot/empty hand, but as long as I held something in hand I could not open door or chest. Tried moving location of door, using a different type of wooden door, reinstalling game - no help.
