Guide to Increase In-Call Volume on OnePlus 3/3T

A simple fix to increase the in-call earpiece speaker volume on OnePlus 3 and 3T. I myself own and use a OnePlus 3 and I absolutely love it. It is also the only phone which I have continuously used for more than a year and haven’t felt the need to change/upgrade to a better phone. The OnePlus 3 and 3T simply keep getting better and better with every update! While the phone duo is absolutely awesome, I happened to come across a tricky situation where, all of a sudden, my in-call volume dropped. The voice at the other end was very feeble and it was very hard to understand. If you have come across a similar situation, here is a fix to that will increase the in-call earpiece speaker volume on your OnePlus 3/3T.

Some values of the speaker’s attributes are changed in the modified version of the files which results in better sound quality during calls.
