None of these can fix security issues in the binary blobs provided by the chipset manufacturer. And since this includes display drivers a security issue in the binary blobs is open season for every App on your phone.
If an App or website has access to an API backed by a binary blob supplied by the hardware vendor then keeping Android itself up to date will not protect you.
(Has anyone tried to exploit an old Android phone via WebGL? I’d presume that it’s feasible to exploit display driver bugs that way, which makes browsing the web on a phone without current security support problematic.)
