Echo problem

[mahmutelmas06]

Hi
I am using Samsung Galaxy A5 Lolipop

There is an echo sound while talking to someone. The person who i talk hears his own voice back.
Is it software problem or hardware ? Should i give my phone to service ?

Try a factory reset and then try again.

And it does it on custom ROMs too? If so sounds like service time
