Ok my turn to finally chime in, my device has been so laggy (S6 Edge) I've also had finger scanner issues. The network for my phone is having trouble handing off and sometimes I'm just stuck on 3g. I tried PRL updates and profile updates but I get a connection error, so I can not update either. I called sammy to try to get a replacement and they said they do not offer replacements just repair. They want me to send my device away for 14 days without a phone. How ridiculous? What other options do I have. I see everyone is raving about this phone online but I am having unacceptable issues. Battery performance is extremely poor also.
