Android Question Access to Blackview BV5200 PTT hardware key

[junglejet]

This smartphone has an external key that can be customer configured as PTT or similar (Zello does it for PTT).
Does anyone on this forum know how to access this key from B4A?
Thank you

Have you checked whether it raises the Activity_KeyPress event?

Thanks Erel, I found the relevant threads after some more search (for "PTT button"), and it is as simple as it sends KeyCode 27 to Activity_KeyPress and Activity_KeyUp.
