Oneplus One microphone audio issue
- 
 Hi All, I have sourced 2 Oneplus One phones and installed UT on both. One of the phones is going to an Android user who I have convinced to use UT as their daily driver. I will be providing support! Unfortunately both phones display a recognised microphone audio issue, low mic volume and an unbearable echo when using speakerphone. The issue is referenced here:

 https://forum.xda-developers.com/oneplus-one/help/microphone-issue-oneplus-one-t3502558A solution under android appears to be tweaking the audio related values in build.prop . Could someone outline briefly for me the steps needed to edit build.prop, if it even exists under Ubuntu Touch? Is there a better way to tweak microphone/speaker/audio settings under Ubuntu touch? Has anyone else experienced the issue on their Oneplus One? Thanks folks, love this project, will be sticking with it and have donated.
