Screen resolution flipped to 'portrait mode' on LegionGo/Onexplayer

Some players complained of my game not showing properly on LegionGo/Onexplayer devices, due to “native portrait mode”, So resolution shows flipped (like 1920x1080).
Is there a know way of dealing with such cases? Thanks

I’ve set the resolution to be swapped back on such cases, hear no complaints but I will keep this tab open on my browser until I hear feedback again
