Testing implementing 3cxphone on Samsung Galaxy S5 for mobile workers. What I'm noticing 1st to be a couple of issues: 1. Incoming 3cx call is not bypassing the screen lock so you can answer it. Once in a while it does, but mostly you have to unlock the screen 1st to get to the 3cx app to answer the call. 2. Bluetooth paired to car kit. Audio seems to work with the two car kits i've tested (subaru OEM, Parrot color 3200 LS), but the answer and disconnect car buttons do not seem to work. Have to answer and disconnect call with the 3cxphone app itself. any ideas on these two subjects?
