This problem had started up recently on my Samsung note 8. Whenever I receive a call, the other person I'm talking to is not able to hear me unless I'm on speaker. Is anyone else having this problem? I tried restarting my phone, it doesn't work. I have not used my bluetooth at all so that's out of the question. I checked blue tooth settings just in case and everything is turned off. I don't know what the problem could be. Barely had this phone for a month, so it's pretty new. When I receive calls, it's still the same issue. The person is not able to hear me unless I put my phone on speaker. Does anyone have a clue on what might be going on with my phone? I really want to avoid resetting my phone, but i will do it, if that's the solution to fixing this annoying problem.
