Ok my friend go this phone and she is having some trouble. Hoping someone can help her out. She says she didn't install anything before her sense UI stopped working. Right now she has the regular android UI going and she cant get it back. I had this happen once, but when i restarted it asked me to chose which one i wanted to use and that fixed it right away, but it doesn't do that for her. Is there an option somewhere or does anyone know of another way to get it back?
