Solved: Yanhua Mini ACDP 2 Android USB Connection Issue

 Here we’ll provide the solution for Yanhua Mini ACDP 2 Android USB connection issue. When connecting ACDP to an Android phone with USB cable , the USB prompt pop-up window doesn’t appear in the software. As a result, the ACDP can’t be connected for a long time.

At this moment, we need to check the status of the OTG switch on Android phone.

1. Go to "Settings" of Android phone;
2. Enter "OTG" in the search bar, click on "OTG connection";
3. We can see the prompt that "Automatically turns off not used for 10 mins", turn on the OTG swtich;
4. Go back to ACDP software, the USB prompt pop-up window will then appear, click "Close >> OK".

Now the Android phone can be successfully connected to Mini ACDP.

Problem was solved!
