Speaker phone problem.

Did you tried to use another network ? If yes then its may b hardware fault. Get replacement asap.
For try you can reset your software but must backup your data first.
What it will do is reinstall software freshly which can also help to fix bugs.

Just bought S5 (SM-G900H) from India. I have the exact same problem as the OP. If I put the call on speaker the person on the other end can not hear me clearly. As such, the speaker volume is too low and feeble even if I put it on maximum volume. My wife's Moto G3 is at least three times louder. Also, I think the mic is too insensitive. Unless I speak pretty close to the mic the person on the other end can not hear me. On my previous Galaxy S2 and Xperia Z3c I could put on speaker and leave it on the table. I could be even few meters away from the phone and I could still be audible to the other person. I am in a good network (AirTel) area. You think its going to be a hardware issue and I should ask for a replacement? Or is it something that can be moded if I root? I am still on stock 4.4.2, not rooted and not having any case on the phone.
