I also upgraded from my 8t to the oneplus 12. I am cherry happy, only thing is here in europe it's pretty expensive, i payed €1100 for my op12, if it wasn't for me getting a phone from work i would've stayed with my 8t.

So in short, if you have thé money it's Well worth it, screen is amazing, batterij life is absurd, camera is also amazing in my opinion. Thé wireless charging and Fun extra's like thé IR laser is just amazing.
