It is hard to tell without more detailed information. I'm guessing you are using CF2 as CF1 doesn't have bluetooth capabilities. Can you see the Crazyflie 2.0 when scanning with the Android bluetooth manager?

Are you standing close to the switched-on Crazyflie when you are trying to connect?

This is strange, we have never seen consistent bluetooth connection error (I have seen intermittent one only, like once every 10 connections).

Is it possible for you to try with another Android device? this would allow to find out if the problem comes from the phone or the Crazyflie.

Ok with Samsun Galaxy S4 it works, while with HTC one A9S it doesn't.

That is very strange that is doesn't work with the A9S. Unfortunately we don't have access to a A9S for further debugging. You could try to download nordic connect app to debug the connection.
