Okay I've had this phone for 3 months. I've contacted T-Mobile, stopped at T-Mobile store and they have changed my SIM card and it has not helped. My actual phone calls sound while listening to other people is absolutely horrible. I struggle to actually hear what they're saying. The sound quality is just not good at all. Nowhere near as good as what my Note 5 had. I've gone in and out of settings and checked things multiple times. When I am in my car and I am linked to Bluetooth the sound is fine through the Bluetooth speaker in my car. But using the actual phone itself it's a no-go. Any tips besides a reset? Thanks
