    Awesome phone but constantly ran hot, I mean hot. Returned it for an S22 Ultra. Having the S-Pen integrated was a plus.

    Phantom silver is such a pretty color that compliments the phone. Good processor. Although, one day it just decided to not turn on- had to get a replacement with Geek Squad.

    I was really excited to get this phone. I've been using a Pixel 2 XL since it was released so I was long overdue for an upgrade. I'd seen all the positive reviews, how amazing the camera is, etc etc. So I picked one up a little over a week ago and my experience has been very disappointing. The phone is very, very fast. It has a lot of great features and the camera is excellent if not overhyped a bit. I didnt realize how big in the hand this was until I was using it every day but I got used to it. Three days into ownership, things began to fall apart. The fingerprint sensor worked only 10% of the time. Whenever I'd play music onto my bluetooth headphones, the apps would play for 10s and then stop. I'd hit play again and seconds later, it would stop. Didnt matter if it was Spotify, Youtube, Tidal, they all did the same things. And finally the phone started to get very warm. Not set something on fire warm, but warm enough to know it was in your pocket. I dont know if I got a dud, but I also know my last three Samsung experiences have not been positive. This included. I honestly just dont know if they can make a quality product anymore. I've had two of their TVs and now this device which all have had quality issues in very short order. I guess I'll head back to Pixel.
