1) Turn on android developer mode

WASD+ needs to use the developer mode to cast screens and simulate clicks.

Operation in Android phone: Settings -> Developer options -> USB debugging

If you can’t find [Developer Options], please do as follows:

VIVO, OPPO, Xiaomi, Huawei, Samsung, others

2) Connect mobile phone and computer with data cable

Try to use the original data cable.

If connecting to the computer does not work, please change the data cable or change a different computer USB port.

3) Allow computer debugging

In the pop-up box of the mobile phone, please check [Allow USB debugging].

4) If the pop-up box of step 3 does not pop up, please change other connection methods

Please change to other connection methods such as: [File Transfer], [MTP], [Charge Only], etc.

5) Win7 or a small part of Win10 does not have a mobile phone driver, please install it

After the phone has USB debugging turned on, connect it to the computer, in the computer: Computer -> Properties -> Device Manager

Check whether the mobile phone is correctly recognized. If [ADB Interface], [HDB Interface], or [unknown device] appears, or there is an [exclamation mark] on the mobile device, you need to install the mobile phone driver on the computer.
