> Everyone is switching to Samsung or MediaTek processors?
Why not? MediaTek is very competitive these days.
It would certainly perform better than a RISC-V decoder slapped onto a core designed for ARM having to run emulation for games (which is pretty much the main reason why you need a lot of performance on your phones).
Adopting RISC-V is also a risk for the phone producers like Samsung. How much of their internal tooling (e.g. diagnostics, build pipelines, testing infrastructure) are built for ARM? How much will performance suffer, and how much will customers care? Why take that risk (in the short/medium term) instead of just using their own CPUs (they did it in some generations) or use MediaTek (many producers have experience with them already)?
Phone producers will be happy to jump to RISC-V over the long term given the right incentives, but I seriously doubt they will be eager to transition quickly. All risks, no benefits.
