Speaker on my sony z750 not working. I can hear incoming but, no one can hear me.


Hi, when no one hears you when you make calls, is the mouthpiece of the phone that is bad. It allows people to hear you when you call.
When you replace the mouthpiece, people will hear you.

Hope you are not talking about the speaker of the phone, Well It's the the same,it's also bad will need replacement for it to work properly.

Have a nice day.

I can hear incoming calls but they cannot hear me with the chocolate touch cell phone-any ideas?


hi, your phone has a speaker...whenever you talk it is this speaker that allows the other person at the other end will hear what you are saying...so when this speaker is faulty, you will not be able to communicate with the other person...all you need do is to change the speaker referred to MOUTH PIECE.

I have a verizon razor but the ear speker went out


This is a common issue with the Moto Razor and can only be fixed by replacing a part. This phone uses different speakers for speaker phone and talk modes.....If you have an old razor laying around that is the same model, you can use its speaker if you believe or can prove it works......otherwise you can buy one for a few bucks. Here is a randomly selected site that sells these parts.
1. Remove the 4 plugs over the screws on the flip top and the screws themselves. 2. pop the top apart and up at the top you sill see where the speaker just sits in there. 3. Replace it the way you saw it in there 4.put it back together Now you can hear your friends without speaker phone!!!
Good Luck!!!! ANd pls rate this post

Cant hear incoming voices unless i put it on speaker. Can hear rings and all phone bells and whistles though. just not earpiece volume for incoming calls unless on speaker


this sounds like a broken earpiece speaker you might be able to find a replacement one on-line and replace it or if its still under warranty send it back in and get it replaced
