I've been using my phone for about a year now, but suddenly I can't hear the other person on the other line. But if I use hands-free, it works. HELP
Let a technician have a look at it?
This is an easy one: There's something wrong with the phone.
have you turned it off and on again......?
Has the volume control been adjusted (inadvertently)?
Meet a technician and get your phone repaired, if you want to get back to using it soon.
Disconnect and again connect or give a complaint for technician.
Sounds like you need to take it to your provider and have them look at it and possibly replace.
