    First off this phone was nof sealed properly. You failed to seal the phone properly. These phones are supposed to be water resistant up to 1.5 M. I accidentally submerged it 6 inches, pulled it out less than 2 seconds later, it stopped working until I took it to a Repair shop to suck the water out, and rhen it started working again 3 monts later the SIM stopped working. I had tmobile install an eSIM but still no signal. I sent it directly into SAMSUNG for repairs and THEY COULDNT FIX IT. Why cant your Geek Squad fix Samsung phones if you sell them?? Horrible experience with this purchase.
