    Hi. O recently bought a slightly used Oneplus 5. Awesome phone, but I do have a problem. About 30% of the time I make calls the first time the person on the other end can't hear me. If I make a call immediately after- everything seems to be fine. Anyone know how to fix this?
    I am using a Gear S3 and sometimes the phone decides I want to use the bluetooth hands free system on my watch - I just thought I should mention this in case that's linked.

    Whoever sold you the phone was using Beta OS version which can have be problematic because it's for testing purposes.
    If you're happy to be a beta tester then stay on that OS otherwise you would need to install stable OS (latest is 5.1.5).
