Bad call quality C103 - Coolpad Cool1 Questions & Answers

Hello, I have a problem with my Cool 1 C103. People are complaining that don't hear me well. Low sound volume and bad quality on my voice. Does somebody has the same issue and can it be solved by installing custom rom or something? Thanks!

[Q] Bad call sound quality for the ones I call

When I call someone they often complain about that it's hard to hear what I'm saying. When I use a BT headset the quality is fine. I've used both the stock Rom and MIUI. But all have this problem.
Anyone else having this problem?
Yep, this is a known issue...with mic volume, have a look at this:

Sorry mate.
Hyperion is a banned rom (the last version which was put on xda).
So most people here will not be able to answer you as threads related to banned roms such as hyperion/nemesis are not allowed here. You can contact the rom makers by others means such as social networks(facebook) or email.

[Q] How to enhance the mic volume "on headphone"

When I'm using Earpods(from Apple) or headphone(from HTC Desire HD) to make a phone call, I encounter a big problem of very low mic volume. Everyone I talk to says that they almost cannot hear my voice...
I've tried many mods here like AwesomeBEATS, BEATS+XLOUDER and faux's kernel sound tweak.
But none of these tweaks the mic volume on headphone.
Is anyone have same problem?
Is it possible to be fixed?
Sorry for my poor English...

I have the same issue but with the speaker phone. I think my handset is faulty.

Low quality call

Hey everyone,
I'm happy to have my xiaomi redmi 3s but there's one problem: the call quality is kinda bad compared to my old phones (even with the high volume you can't hear well).
I've tried other sim cards and tested the reciever and is working with a excelent sound so it must be a software problem. Anyone can help me to fix this?
I'm using the last version of global stable rom btw.
Exactly what do you mean by "call quality"? Is the volume too low? Is there noise? Is the tone too high or too low? Please try to be more specific.

The volume is too low and you can't hear well when you're in a public place (I didn't got that problem with the old phones because the high volume was enough).
The "quality call" is when you're talking with someone and the volume is low.
I have no problem with hearing the other party when I'm on a call. Maybe something is wrong with your phone. You should take it to the service center.

How to fix low mic volume in custom roms?

I would like to preface this by saying I love all the Custom ROM's available, especially the Android 10 ones. But, I've noticed one problem shared by all the ROM's I've tested so far (almost all). It's that the mic quality is simply horrible on every single one of them. The first thing I do when I download a Custom ROM is to test the mic using the Google Recorder app and so far, no custom ROM has even come close the loudness and quality of stock. I wouldn't mind if the mic quality was bad, but that's not the biggest problem. The biggest problem is that the mic VOLUME is extremely low. I have to shout while calling just so the other person can hear me. How do I fix this problem? The same problem cropped up a lot on Pie ROM's too. I've tried editing the mixer_paths.xml but I don't really know where to look.
I would greatly appreciate if anyone could help me. Cheers.

Use kernel with mic gain and increase it to your liking.
