I'm brand new to smart phones, and recently upgraded an old Orange Rio to a Samsung S5. I purchased it second hand from eBay, and I think it's possibly locked to o2. Today I got my new SIM from Virgin Media, my current provider, and after inserting it into the S5, when ever I start the phone, I get a message saying
"Unable to use fingerprints. Device Restarted. Enter backup password, then fingerprints can be used next time device is unlocked."
However the screen shuts down within a second or two, but always before I can enter the password. I have tried removing the SIM to see if that was the issue but it's still doing it.
What is happening please?!
