Hello there! Try to unplug the OTG cable and USB from your device. Then plug in again the connections to your device. Check that your device supports OTG. Your phone's software must be able to support it, such that Android versions above 3.1 Honeycomb. 🙂
The OTG cable you have may not be compatible with your A50 device. Test out the OTG first before purchasing, to see if it is compatible with your A50. 😊
