Farhan2522 , via OnePlus 5T , Feb 15, 2021 : Recently for 3-4months i am facing some issues while calling over my sim network! The receiver hears only some parts of the messages i speak to them! Moreover the call hungs up automatically after 30-40seconds! This problem occurs while using every sim carrier available in my Country (Bangladesh)! Again while using mobile data, the phone gets heated extremely! But over wifi everything seems fine! This calling problem doesnt persist while i call someone over the internet! The receiver hears everything properly! Voice recording options are working fine! Video recording, calling all works fine!! I have hard resetted my phone twice or thrice, but the problem wasnt solved! Is it a hardware or a software issue? Is there any solution to it? TIA.
