Has Anyone Experienced this Kind of Freezing???

It seems my problems are sorted now. I uninstalled it from the device, then turned the device off, making sure it was at least five minutes, opened it all up and I went straight into the start of the game. I came out of it and forced the game closed, went back into the game and went to the log-in page (although previous times I had similar problems I've had to complete a little of the tutorial, and force close a second time). After that all was fine! :)
