Major lag, then crashing on Android

Heres the steps. Load a new world on Android. You will see the lag, then after a couple minutes it crashes. Even on my older worlds. It played ok for a minute then starts lagging terribly and crashes. I cannot upload the videos the files are too big. Try it for yourself on Android. We need a hot fix. I've been playing since 7.0 and never had this bad of a problem.
