The game stoles my blocks, objects and time

Hi.

I'm very upset since the 1.5.5 update of Minecraft Pocket Edition. Since the update came, the items in my inventory always disappear, I lost a lot of buckets, swords, and other materials that cost me a lot to get.

Every day I regret more having bought this game, at first it was all great, now everything is wrong.

PS. : I have a HUAWEI Mate 9 (Model: MHA-L09)
