Low volume I have been using the bluetooth since a year. In the recent days, I am experiencing low volume issue in bluetooth and not able to hear the person who is talking

It seems a known issue. You could use the speaker or use a Bluetooth earpiece.

Did you increase the Volume whilst ON a call? Otherwise you are just turning up the ringer volume.

Disconnect it then reconnect it

Your mobile hardware needs repairing.
A problem in the speaker ..it needs to be changed

If you have bluetooth headset or can borrow one, see if it works. this should help in finding if it's a hardware or software issue we need to look for. Please let me know.

Whilst on a call in bluetooth mode change the volume. It needs to be for each different "speaker" you use

the problem came from hardware, a poor speakerphone contact. If you press on upper part of your bold, the ring volume will be increased.
So, the workaround is to insert between batery and backcover a folded piece of paper to press the upper side of phone.
vincentvince, you are a little bit too ...

Hi,

Check to see if you have not muted the headset or the phone.

be sure there's nothing covering the speaker when you're talking. i would try looking in the tones settings if you have that. but some phones just don't have really good audio, but if this is a recent problem, then i'd suggest taking it to the store and getting it looked at

I had the same problem after I got my 15K service back in April. I brought the car back and they said they cranked it up to the max but it was still too low. I started researching online and found out that I was not the only one with this problem. I even forwarded this link to the dealer. I told them that Audi must have a solution for this because it is not an isolated issue. Thankfully, there is a solution and my bluetooth was fixed last week! Audi recently sent out TSB (technical service bulletin) #2018475/2 which is apparently a "radio adaption" as stated on my invoice. My bluetooth is now back to normal. You all should contact your local Audi dealer and reference this TSB so that your bluetooth issues can be fixed.
