Major problem in entering and creating worlds

I was usually playing minecraft pocket edition on my verykool cell S353 , at one point I was running on my character and I closed the game went into my infinite world my of said error: I0 and create a world also is the same. .

What I expected to happen it was ... :
Get back into my world and play ..

What actually happened was ... :
Which in turn , said world error (error: I0 )

Steps to reproduce:
1. Log into my world.
2. See if the problem is solved by itself .
3. Note that the problem is not resolved and could not create another world because I said my world error: I0 .How am I supposed to play now ?
