Not sure why you are getting downvoted, because its true. Qualcomm is one of the main things holding Android devices back, and their driver policy is shitty.

I don't suppose someone could point to more info on this?

It's the same reason why your home router runs an ancient version of Linux that can never be updated. The hardware requires a proprietary firmware blob that only links with a specific kernel. You can never update the system independently, you're at the mercy of Qualcomm releasing updated blobs.

Basically Qualcomm only releases proprietary Linux drivers for their chips, provided as a precompiled binary blob, and they only offer ~2 years of support before dropping them all together.

Because the Linux kernel does not have a stable binary interface for driver modules, getting an old driver to work with a new version of the kernel can become a hacky nightmare.

If you saw the code you would thank your stars no one can see it.

They're also the reason behind the shitty Arm PCs. I despise Qualcomm.

At least they're better than Mediatek afaik
