Switch camera icon on left or right side? [closed]

I'm building a custom snap-photo flow in between another flow in my App. So here I have an interesting dilemma.

Should the Selfie/Rear cam toggle icon be on the left or right side and why? [image below]

Data points

  1. Majority of my users are RIGHT handed

  2. Majority are iOS users

  3. Default iOS camera app has it on RIGHT side

  4. Instagram & Whatsapp has it on RIGHT side

  5. But, Google camera app has it on LEFT side
