Samsung Gear Vr

Hi guys, I wanna ask you a question. I have Samsung Gear Vr but i ise xaomi mi 6. I wanna use it on Samsung Gear Vr but they optimized just Samsung phones. I tried download oculus from Google play store but is not correct apk. They said at samsung original site. Then I search for correct apk but ıts downloading automatically when you connect your Samsung phone to Samsung Gear Vr. Can I find optimized APK from somewhere?
