It's sad to hear that your S6 Edge is now a paperweight. As far as the upgrade goes, there were a few hiccups in the beginning but those have been ironed out. Can you tell me what baseband version you're running on? To find the baseband version, follow these steps:
- From the Home screen, tap the Apps icon.
- Tap Settings.
- Tap About device.
The reception is the same on my phone, just watch out for wi-fi calling because it will force you to restart your phone every time you reconnect to wi-fi.
