Ok so, at some point while playing pokemon white you've got to go into the amusement park and are brought on the ferris wheel by N. Right when I walk through the door to get on the ferris wheel I get a never ending black screen. Is anyone else having this problem??? Please help!

Also, I'm using a galaxy s4

This is happening to Pokemon Black too and the cause is a corrupted badly patched ROM, a proper Google search should yield good results.
