A question about nrf52840 USB connection to android

Question

Hi all, 
 I am working on nRF52840, nRF5_SDK_15.2.0, pca10056,usbd_cdc_acm 
 I can now communicate nrf52840 with PC,However, I failed to connect nrf52840 to android, Android recognizes the device,But we can't communicate 
 Can we communicate with android normally?or need some special Settings? Any examples? 
 The example has not changed 
 
 Thank you!

Hi 
 Sorry for the slow response, around Christmas and new year we have very limited staffing. 
 Can you let me know which Android device you have tested? 
 Also, have you tested more than one, or just this one device? 
 How do you try to communicate on the Android side? Are you running some custom app to access the comport? 
 I will check with the USB developers if there is any trick to get the CDC example running on Android, but I think it should work out of the box. 
 Best regards Torbjørn Øvrebekk
