25. In the Bluetooth control interface of FiiO Music, Q5s can not be connected, or unstable

RE：Q5s and mobile phone are connected by audio + control dual mode. If the control interface is unstable, please try to clear Q5s from Bluetooth pairing (Bluetooth state, while pressing the previous one + the next one), or reset Q5s (long press reset more than 5s) and then re-pair with the device.

① Previous track (Bluetooth mode) ② Pause/Play (Bluetooth On/Off) ③ Next track (Bluetooth mode) ④ Reset
