They tend to hard reset the phone. Hope this is not where you learn about backup of the phone data.

I have a new Samsung Galaxy 5.
I locked my phone with fingerprint lock and it decided it won't work. My only option now is "Alternative Password" Which I don't recall making one. I can not locate my phone through " Device Manager" to erase or make a new password as my LOCATION SETTINGS is off.
What do I do? I called phone tech services, Telstra ( My service provider) and Samsung plaza ( I am still waiting for samsung tech man to call) No one can help me.
I am on my last resort and I need to get into my phone a.s.a.p please!
