I have installed AD and a few apps (excluding the linphone) but have not got the chance to test them yet. I'll report once I got the result.

The changes in wip0.19 are:

• the findutils tool included (maybe this is not a benefit for many but I prefer to use the locate command to find files/folders)
• a new pa file (arm_qualcomm_msm_8974_hammerhead_flattened_device _tree_000b.pa) in /etc/pulse folder from John Galt's repo. I thought this could solve the recording issues, but it didn't.
• the '-mapplauncherd-booster-silica-qt5-media' is enabled when I did the build. This is for faster camera start (I am not sure whether the camera starts really quicker but the comment in the file suggested this to switch on for devices with 2GB or more ram.)
