karankaruna , Oct 26, 2020 : I'm using OnePlus 7 device. since last update, sometimes I can't make/recieve calls even signal is strong (internet working perfectly, I do even make video/voice calls on whatsapp) sometimes I do can make/recieve calls but I can't hear a single word from another end (but they can hear my voice) After restarting a device only, I can perfectly make/receive a call and hear another end. and it's not good. now I'm restarting my device for 20+ times a day due to this issue. please solve this issue, I hate to use my OnePlus device because of this.
