Low in-call volume fix
Hello everyone.
First-off I'd like to thank the OP for this great Rom... been using it for almost a week now and it's mostly perfect. There a few bugs here and there (fp stops working sporadically, heart-rate sensor not detected by Samsung Health, low in-call volume... these are the only somewhat bothersome ones), and I'm gonna link a fix to the most annoying bug which is the low in-call volume... I've flashed the file in this thread:
https://forum.xda-developers.com/galaxy-s5/general/mic-volume-gain-mod-s5-t3491483 and until now it works pretty well. I can hear the person on the other end of the line clearly and the volume has significantly increase, that said the other person hears a slight echo of their own voice when they talk to me... guess it's a small price to pay. This fix has only worked for calls, the voice recorder still gives a low out-put.
Hope it helps anyone who's bothered by that bug, and hey, it working for me doesn't necessarily mean it'll work for everyone. It goes without saying but I only tried the fix on my SM-G900H running this specific custom rom.
