Creative Flight Mode Error

I do not know if it's just me, but when I try to land holding the arrow down we do not stop flying ... Even in a super low altitude.
The normal thing would be that when we went down with the arrow, we would walk again.

My Device: Android - Sansung Galaxy Gran Duos - Jelly Bean - 4.2.2

Note: In addition ... My Minecraft has closed by itself quite often when opening the store, logging in to servers, joining Xbox Live or playing for a long time ... This error can be caused by the simple fact that every time I enter the game the Plutonium Mode is active.
This is just an additional note, ie I will not create another ticket.
