Never mind the December security patches, Samsung haven't even released the November patches yet, the ones for the critical severity RCE. Unless you have a "major flagship model" [1], because apparently only the richest users deserve to be secure.

Why would you want security, if you get 'play integrity' for phones that received no updates since 2 years. Google's current security practices are more than dubious IMHO. Now they are not releasing any source for security patches for 3 month, to 'protect' vendors that are too slow updating. As if there is no chance for bad actors to reverse engineer those patch sets.
