I've just installed minecraft on my android phone for my son. Whenever I create a new world, regardless of whether I use external or application for storage, I try and load it and get an error message "There was a problem loading this world."

I've reinstalled it three times, tried changing different settings, and allowed minecraft access to storage on the phone, but nothing works. If I can't load any world I create, minecraft is unusable.

Please can you help?
