This is one of the most common issues we see — and it’s usually down to how the phone is held.
Chatsie phones are a little larger than most, so people sometimes hold them like a landline: with the very top of the phone against the very top of their ear. But the call speaker is right at the top edge of the Chatsie — so if it’s sitting above your ear canal, the sound can miss your ear and seem faint.
Quick tip: Try holding the phone so the top edge is level with the middle of your ear canal, not above it. This small adjustment makes a big difference — many customers say it instantly makes voices clearer and louder.
