This is not factory unlocked, at least not the one i received from wcell. It's not even unlocked. Has bad software versions that won't even allow you to do a software update for the phone, even if you did have it on sprint.
The facial recognition works for me 3 out of 4 times. The charge lasts a long time. And this has a bigger battery, which is nice.
The fingerprint reader is horrible. It works occasionally. It's slow and glitchy. Just don't buy one from this seller expecting it to be unlocked.
