How to use the app?
USB mode
Plug a USB into your device (use an OTG cable only for tablets), make sure you let HUR be the default app for activity when requested, and always check the box.
If you’re running the app on a device running Android .0.0 or higher, you’ll need to drag the notification bar and select the connected USB device before the app starts (it depends on the device)
If the app doesn’t start automatically when you plug in to your phone, you can always open HUR, tap the USB button, and select the phone from the list.
WiFi mode and WiFi direct
