Just got it on unlocked phone. We also had the fingerprint sensor update earlier in the week which made it so much better.
I have an unlocked +. For me, I wouldn't say anything got better with that earlier update. Still using the factory screen protector, FYI. Honestly I kind of feel like it got a little worse after that one. Not like, Oh my I can't get into my device, worse, just not as good as it was. After that update, literally days ago, I got kicked out of most of my sign-in with fingerprint apps. Bank of America app flashed a warning about Samsung FPS and just won't allow me to use it to sign-in anymore. I first noticed that Samsung Pay wouldn't recognize and/or accept my fingerprint. So I made a new one and signed in to all of my FPS sign-in apps, which then wanted me to re-agree due to the security change. All except BoA of course. I found it odd that it wasn't until I got the update that all of this happened. Seems like all of that should have happened, I get the update, everyone breathes a sigh of relief and everything goes back to working. Hopefully this does make things better, or at least as good as it was before. I'll have to wait until I get home tho, no WiFi. Thanks again Samsung... I totally don't get the need for WiFi for updates. I can't get it over my trusted carrier's data but I go to some seedy public WiFi spot, that's ok? Alright, just checking in to see that I'm not crazy and didn't just download an update a few days ago, only to find another one waiting for me. Hahaha
