Dear, Mojang
I think this bug only happens when you connect a bluetooth keyboard to my mobile device. When I join any kind of world, its all good, but when I open the chat and then close it, it dosen't alllow me to jump when I click the space bar, I don't know if this has only happened to me but im hopping you can fix this bug ASAP because I love playing minecraft and the ability to not jump isn't so fun.
