Sometimes, when quitting and saving the world while underground, the game vertically respawns me to the top surface when opening the world again.
Update by rplatham:
The most general description of this bug so far is: Whenever you reload a world you always appear one block (or part thereof) above wherever you last quit. How to reproduce: You can easily test this bug by quitting your world in 3rd person view and watching as the world loads you will drop 1 block. Try it in creative flat to see what I mean.
The bug becomes a problem when you quit and the block(s) directly above you are solid. Upon the next load, you will spawn at the next available 2 block space moving upward from where you should have spawned. Again in a creative flat world, put a block above you, quit, reload and you'll be on top of that block. This works all the way up to the build limit where you spawn with your lower body inside the top block.
Two closely related and much older reports are MCPE-51 (assigned to Johan) and MCPE-330 (unassigned).

Confirmed on Nexus 5 MCPE 0.11.1 Android 4.4.4. I spawned in a underground lava lake, and all my things were lost. All that procastination while mining in vain...
That even happens in multiplayer when someone disconnects and connects again
