Man that is a huge list to go through.
I would definitely recommend you to go for some other Smartphone other than Samsung as I feel they are very overpriced. Yes their Cameras are awesome and is definitely a step above others but that doesn't justify to pay double of what we pay for some other Smartphones.
As for GoPro you can start crowdfunding. Make one Post per day and save whatever payout it gives out strictly towards buying a GoPro. I am currently doing that😅 and I am hoping to reach my target when the new model comes out.
I'm willing to pay the price for that camera. It will be future proof for the next four years for me and I would be buying my next phone in 2022. I saw a lot of reviews of comparing that camera with the camera used in the film industry and stuff. That thing's a beast. If not beat the industry cameras, it comes really close. And I'm sure I can cover up that extra cost with the photography made with the S9+ camera.
How does crowdfunding post work? You make the same crowdfund post again and again with the same content? Good luck to you man!
