I apologise in advance if this is not the right forum but I wanted to share my experience as an ‘apprentice’ Android developer trying to test on a real phone. This would be the 1st ‘challenge’ once Android Studio 3.3 is installed and the Emulator was tested, but then you want to test on a real device.
My Oppo A3s seemed incompatible with Android Studio 3.3 (it finds it as a USB device, but does not recognise it as a Connected Device). I spent 3 days research on this. So, I bought a ‘generic/no brand’ phone for $70 and it worked fine, not a single issue and nothing but the Enable USB Debugging routine.
Grateful if other Android aspiring developers can share their experience with their phones, as I need to buy a ‘quality’ phone going forward. Thanks in advance.
