How can I play a 360 video that is 1.6gig?,Cant play a 360 video that is 1.8gig

When I create an apk with just one video that is 1.6gig the video is not playing. The Unity app appears all ok but when I go to play the video it takes me to a black screen and no video plays. The apk does not exceed 2gig. If I reduce the video to 500mb it plays perfectly in the app but the quality of the video is quite poor. Is there a solution to this?,I am wanting to create a Unity app to play just one 360 video. The video is around 1.6gig and when the app is created, the apk is still under 2gig. However, when I gonto play the video it is just opening a bkack screen and the video does not play. If however i reduce the bitrate of the video when saving it in Premiere Pro so that the video is about 600mb, it plays fine in the apk, but thw quality of the video is very poor. Is there a solition to this?
