I have a samsung A5 it's 5 months old I have had no problem's until now the last 3 weeks I'm having problems when certain people ring for a freind bought a new handset a samsung J3 and when she rings she sounds like a robot but I sound fine to her this is also happening on my mum's phone she sounds robotic but I sound fine to her her phone is a newer model samsung. BUT all other phone calls are fine I hear people crystal clear and vise versa it is just these 2 phones I'm having problems with so far can you help.
Hi Tilly. Try making calling each other using video calling apps like Skype. If they still sound the same, the problem is on their mic.
