Early today the developers submitted 0.10.3, that fixes crashes occurring on android and iOS devices all throughout the past 0.10.x versions.
Johan says on Twitter:
(Hopefully this means majority of crashing from the new 0.10 version will be stopped on at his newer version upcoming.)
Another change/feature in 0.10.3 is stated on the Minecraft Wikipedia:
(This sounds like a new button named “Quit To Title” will be possibly added to the menu screen with-in the Minecraft PE application.)
Hopefully the iOS version of 0.10.3 rolls with-in the next few days. Stay patient with the developers, they work their hardest to make us users happy!
