Prudhvi4p , via OnePlus 8 , Apr 14, 2021 : I have OP8 and for the past 4 months I have issues regarding call connectivity. If I call a person, he/she will not be audible for the first call. I call back and then it's fine on the call. I thought that it may be due to my SIM and cellular connectivity. Recently I purchased another SIM of a different Network Operator. The same issue with the new SIM too. It doesn't matter which location I may be in. I have asked other friends with similar cellular network but different mobiles and they don't seem to have the problem. Anyone else with this issue?
