Been my daily user since release date (pre-ordered).. Besides the screen not being bright and an occasional lockup/restart, best phone i've ever owned.
Previous S8+ owner, I couldn't stand Bixby, the curved screen and screen protectors/cases.. The location of the fingerprint scanner, crappy sound... I could go on.. While the camera was nice... I chose the razer..
Actually using a vibration tester, while vibrating I pressed down on the lower speaker area.. Sounds normal now.. I think it's actually the speaker grill or something else that was loose...
After having the phone a bit, I will have to agree that call is very quiet.. Even turned up all the way... In fact you have to have it up all the way just to be able to have a conversation.
Mine appears to have a better signal then my older HTC and S8 plus.. Not to mention the GPS on Waze while on my S8 plus would sometimes be off and move around, so far my Razer has been perfect.
