There's still one fix that, sadly, did not find it's way into OTA-3. But it will ship with OTA-4.

On OTA-3, if you receive or make an call and you go for an app that uses the microphone will not capture sound. DialerApp remains ok.

A temporary workaround is already available in the Devel Channel.

Hi, its possible to have the cameraApp accessible (for quick photo video capture) without the need to type lockscreen pin first in the future or is something the platform can't do, technically speaking ?

Thank you!

I've ordered an 6t. Maybe tomorrow I can give feedback. Thank you @SevralT !!
