Unreal Engine not showing Android device but it did earlier

I don’t know what happened but I used developer mode for the first time in my Android 4.4.2 and it worked well. I did everything to deploy maps on my Android device and it worked well but when I disconnected my phone in developer mode and connected it again to my PC, my device is no longer recognized by Unreal Engine 4 but is shown in adb devices.

This seems very strange to me. I have got no clue!

Dude i got the same issue :O!!!
