Wait for a while it will automatically switchs to normal lense. And now try to zoom in you can't find a view. Because on screen it seems like you are looking through 2x but actually it is main lense through which your are taking photos most of the time.
I was cleaning my lense while my screen was turned on. and suddenly I've realized that I am covering main lense then why the hell 2x lense is not showing anything. then I tested it evenly as I've mentioned. so it was actually switching continuously between main and telephoto lense. so till date I was fool thinking that I am taking lossless pictures with 2x lense.
