Tested on Samsung Galaxy Note 5.

When using the 3rd person back/front perspective, and when checking the survival inventory (either in survival or creative) the player's head starts to rapidly spaz out of control.

To get a good view, position yourself where the player's head takes up the most space and proceed to check the player's inventory.

Note: I first noticed this effect with using the Player Render HUD Addon, but have removed it to see if it was fixed, but it didn't.
