I have found a very weird bug in the latest Android beta build.
To get the bug create a new world and go to resource packs and add one to the world. After that click the ! Button under the resource pack
After that you will get a screen of static and if you click the back button on your phone enough times you will be on the main menu where if you spin your skin it looks weird and made of triangles and if you hover over the buttons the screen changes and if you click the back button it will change as well.
*The resource pack I clicked the button on was Custom UI
I also added Mine-Tornado Textures witch did not have a ! Button
I also have the Mine-Tornado Add-On
Also my world would not load as well if I tried to play it it would just freeze my phone.

Some of the chemistry block do not work on Android as well.

If you swim in water you get the fly buttons instead of the jump button meaning swimming does not work right

The texture of flowing water while education edition is enabled is messed up

When I get close to entities they disappear and when I back away they come back. There is also a ring where they will disappear as well but

If you Sprint swim close to the surface of the water but still under the surface you will not get the under water glint.

If you sink to the bottom of the ocean with the down button you will get stuck to the bottom and you cannot go back up and you move super slow
