I am using mobile device as android platform with new device android 15 with set 6 GB RAM, bought official version with lastest in play store and downloaded properly the file but when i import it gives "World import failed" on top screen say, no matter how much i try get world import in.
Sorry, I'm not very familiar with Android devices nor do I even own one. There might be a few resources on the internet to help you get it working. Try Googling 'minecraft world import failed android' or something like that and see what you can find. Sorry again I couldn't help you.
And the world is so good thank you!
