Not a bug, just some annoyances.

The furnace has no recipe book in bedrock. Dolphin's Grace isn't a potion effect in bedrock. You cannot find monster spawners/dungeons with /locate. You cannot target yourself with /kill while in creative mode in bedrock. There is no way to use pick block on android without attachments. There is no debug stick in bedrock. You cannot obtain lava blocks, water blocks, fire blocks, portal blocks, etc with commands or creative mode but can with glitches and hacking. The wither goes through blocks sometimes while charging in bedrock. Spectator mode is not in bedrock. Custom/buffet worlds aren't in bedrock. You cannot customize superflat worlds in bedrock. You have to delete all text that comes after the one character you want to delete in android. When you pause the game, everything continues as normal in bedrock. You cannot sleep thunderstorms except at night in bedrock. You cannot see what block you are looking at in bedrock, but can in java with the f3 menu. You cannot check the exact durability of an item in bedrock, unlike in java. I will probably post more when I think of them.
