I was concerned that I lost my phone earlier and accessed Samsung's Find My mobile. Having gotten a "not connected to network" message I was concerned. Luckily my phone was in an odd place but when I went back into Find My Mobile, I still got the same message.
After calling Samsung directly I was informed the error was caused because I wasn't connected to wifi. So what happens when I'm out, and not connected to wifi? Is there really no way I can find my device? Location services were enabled, and I was connected to my mobile network. Is there anything working without wifi and over my mobile data connection or just my GPS? I'm running Android 5.0 which had made most apps I find incompatible.
