We pre-ordered 2 Galaxy Note 8s and picked them up on 9/14/17. Since then we have had issues with phone calls dropping, talking to a party and they cannot hear us talking. We never had this issue with the Note 5. We did not spend this much money for a phone that cannot be used as a phone.
We have done everything that was said, clear phone cache partition, turned off WiFi calling, I even uninstalled FB messenger. Would it make a difference to take the Sim from my Note 5 and put it in the Note 8 or is this a phone issue. If that is the case I need to return these bricks!
