You can use chromes device preview and emulate this.
Chrome or some other chromium browsers (Ex: opera)
if You pull up developer tools, you’ll be able to test landscape and portrait for a variety of android and ios (even windows phone) devices. It can basically pretend to be almost anything you need, though it wont be able to run hardware related plugins (Camera, accelerometer, etc.)
