Duplication glitch on android

When you want to create for example 2 chests, and you have exactly 16 wood planks, and when you draw across a pattern to make a chest with 16 blocks, they duplicate to 17. This is currently due to really buggy UI, it was better before on non-beta 1.2 versions, the drag and drop, not this I wouldn't even call it an attempt of drag and drop, just bring back the drag and drop because, not just the duplication glitch, but there are some other problems with it as well. For example, you can't see enchantment from inventory or when you are in a chest, the only way you can see them is by holding it in your hand and seeing it. It becomes annoying when you have to do this while searching for the right book, you generally get bored from playing the game. This is not the case on windows 10 edition beta and console edition beta, they still have item info when you use your inventory. Why can't this drag and drop be back and be like on PC, why the sudden downgrade? Please fix it in the next beta.

P.S. The duplication glitch mentioned above is not only for wood planks, but for pretty much any stackable item in the game.
