In my few articles, I’ve already wrote about Phone Client in NAV 2016 and how to install it on own smartphone with self-signed certificate. Also, I already wrote about NAV 2016 system requirements.
But in all of these articles, I didn’t wrote about system requirements for phone client. And now, it is not phone client; it is an NAV Universal App. It can work on any device you have, but if this device meets requirements.
In short, Universal App can work on devices with Windows 10/8.1, Windows Phone 8.1, iOS 8.4 and Android 4.4.3 with minimum 1 GB RAM (for Windows and Android). Tablets must meet minimum 7″ screen size with minimum 960×510 resolution and Phones must meet minimum 4″ screen size with minimum 854×480 screen resolution.
In my older article about system requirements I said that there are not official data, this is my research. But if you want more about official system requirements, try here on MSDN. I hope, this is a clear.
