Hi Richard, I know where the problem is.
The problem is not in the Reasnow S1 firmware.
The problem was with firmware updates and Azeron Cyborg apps.
(I'm back to an older firmware version from wibesite azeron),
after that ,
I've tried the latest reasnow s1 app firmware beta , be it Android or iOS, and I haven't had any issues.
I'm sorry I bothered you
Thank you for your response and efforts. I am very grateful to you
