Unity Camera is 'stuttering/choppy' in my Gear VR Projcet all of a sudden...

Hi

This never used to happen. Maybe a few months ago it was ok, or even a few weeks ago and I haven’t done anything different…except have the phone auto-update whatever is needed.
I tested my project on phone using the Samsung Gear VR and all of a sudden the camera is…how best to explain this?..stuttering/choppy?

-Basically there are ‘2 scenes’, but they are both in the same environment (a room). This issue only happens in ‘scene 1
-The ‘scene 2’ has a camera on one side of the room (a voice-over plays out, bubble particles). Then the scene ‘switches’ to ‘scene 2’, and the camera has switched sides, and is now in the middle of the room.
-The camera in ‘scene 1’ has a Canvas attached to it, with code attached to the canvas telling it to ‘switch scenes’. An overlay saying ‘changing scenes’ is displayed on the camera’s canvas.

I tried a few things; turning off ‘Prewarm’ for the bubble particles, moving the camera in ‘scene 1’ over to the left a little, removing the actual canvas (although scene does not switch as the ‘code is turned off’, and it camera still stutters’.

I dont have a clue as to what has caused this frustrating issue. And I have a presentation coming up this week, so I would like to try and find a fix today

Any help/insight would be highly appreciated, Thank You

Ok Its kind of fixed with baked lighting, but I am having major issues with that so going to post int he ‘lighting’ section.
