I'm not sure if this is a Galaxy 5 exclusive issue or if it's something that happens to some other Android devices, but here it goes. If I turn off WiFi and the turn it on, sometimes it refuses to turn on. I go to wireless settings and it says, under WiFi, error. The only way to make it right is by turning the phone off and on. Is this the only way to solve it? Should I take it to my carrier to have it check it?
