Mediatek has been making phone SoCs since forever now, they have two lines - Helios and Dimensity. They’re used in many phones, usually on the lower end. Even Samsung uses them. Both lines have abysmal custom rom support compared to Snapdragon phones, so I don’t think you can hope for much there.
Well there’s no shortage of those, and they’re unusually cheaper too (unless they’re specced out). I prefer a thin silent one myself, so I welcome this innovation.
