The hand and some items held in hand stop appearing after some time into the game

Hi, I'm playing Minecraft on my Redmi note 4.
The problem is that after playing for some time (there might be a trigger that I may have been activating unintentionally), the hand at the bottom corner of the screen, and some items like swords, pickaxes or food also do not appear near the corner of the screen. They work as intended but there are no visible animations of eating the food or swinging the sword.
