Idk what the heck is going on. I updated my phone to 17.5.1, and since then, the other party cant hear me without using speakerphone when calling.it seems to fluctuate sometimes, too. Initially I thought it was a reception issue, but considering there’s so problem when I turn speakerphone on, I don’t think that’s the case. Anybody got this issue?
