Inventary of 1+ blocks

Model of my phone is XIAOMI S3.
I have an error with my pocket edition when i want move blocks of my inventary.
I could usually hold the touch on the blocks that had more than one element and when I fully load the green bar I could move all the blocks, to a chest for example, but lately I can not do that, when the green bar loads completely it moves only one block. I have tried it several times and it is very annoying to be moving the blocks one by one
