My 3 month old S7 Edge has been consistently dropping calls, while working from my home office or on the road where my old trusty S3 never failed. Signal strength is strong when this happens, I see all bars lit up, or I'm only 1 bar short. I've turned off HD voice, and turned off WiFi assist, problem continues. I have tried rebooting my phone, deleting apps I no longer use. Are other S7 owners seeing the same issue?
