This repository contains some OSS vendor blobs from Qualcomm and some proprietary ones, some of which, may be very useful to developers.
I only just found out recently that the latest commit broke the blobs so I'll have to merge the old proprietary blobs with the added opensource ones, you may use https://github.com/David112x/android-vendor-qcom-proprietary/tree/f3f299708c5f156cd056e52375060e7ce01a24cc for the time being.
