Yes, it does support OTG, which goes a long way toward mitigating the lack of memory card for me. I’m used to carrying a flash drive and 6" USB cable with my current phone and find it easy to quickly move/add/change music, movies, etc., from my computer to my phone.
I’ve ordered the 64GB N6P and will carry a 64GB flash drive. The phone comes with a short USB type C to USB 3.0 type A cable to facilitate OTG. Can also store entertainment and other files on Google Drive and download directly to phone when on WiFi. With these sources available to swap out files whenever I want, I don’t need that much in-phone storage, which keeps the price down.
