This is my first post in regards to the Galaxy Attain 4G. I work on a store which sells MetroPCS. I have seen this error on at least 4 phones being returned to us due to a signal error. Even after power off/on the phone it shows that. Also the phones are restarting on their own and one of them its always on media scanning the sd card. Is there a way how to deal with all these problems? Thanks for any feedback.
