Got mine this afternoon. Just finished setting it up, but I still have lots to do. The fingerprint scanner works quick and easy. No lag or stutter at all. It came with 39% charge on the battery so i charged it as I was setting it up. The supplied clear soft TPU case fits nice and I think I will use it. There were no updates to the OS. I had no issues at all with my 128GB Sandisk microSD card. Signal strength shows 2 bars, but so does my Galaxy S7 Active right next to it. It got a little warm while setting up, installing and updating several dozen apps (but so has every single phone I have set up). Right now it's cool as a cucumber. The supplied fast charger works fine. Haven't had it long enough to judge battery life, but if reviews are correct, I should make it a day with no problem as I'm not a gamer or heavy user.I've only taken a couple of photos in the room with room lighting. They were well exposed and sharp. I don't see any issues with this camera unless you're taking pictures in near total darkness. So far so good with not a single complaint.
