Bolero Bluetooth nit working

Hi folks. I'm new to the Skoda community, just bought a 2011 Superb 2.0 tdci 140. Brilliant car but I'm baffled by the Bolero audio system. When I press phone it shows no user connected. I've tried every Option on the set up menu, I've reset to factory and double checked my phone is set up properly but it doesn't seem to work. In setup.ive activated Bluetooth audio. My phone is Android, one plus x, I've heard that they only recognise iPhones, is this true? . Any how thanks for your help, it's the only bad point in an otherwise top motor but due to my job it's vital I have this set up. Thank you
