ViewPager by default keeps previous and next fragment in the resumed state. So it's like one camera opened on three screens at the same time.
Please, try to

1. Use only 1 fragment with camera view
2. Use flag FragmentStatePagerAdapter.BEHAVIOR_RESUME_ONLY_CURRENT_FRAGMENT for the ViewPager

I've prepared a small working demo, please, take a look https://github.com/3akat/Ziggeo_CameraView_PagerDemo
