Solution for a problem needed for a Google VR Cardboard Blueprint App

Hey guys,
I’m currently working on a google vr cardboard app for a fair. The player is on a moon surface, looking at the planets and short movies will be started (gaze based interactions). It’s nearly finished and when testing it on a Samsung Galaxy S6 it works fine, but on a S7 with FHD resolution it looks distorted.
The App should be able to adapt correctly to different screen resolutions especially on the phones: Samsung Galaxy S6, S7, S7+,S8, S8+
I need a quick solution and will pay for it.
Please contact me.

Best regards,
