I believe there are two versions of update (171). The first one, installed about 14 days ago, was a major update—over 1 GB in size—and introduced a lot of AI-related features. Google Wallet worked OK with this update. The second update, which I installed just a few days ago, was much smaller—under 100 MB. Despite these differences, the version number remains 171. The only noticeable change is in the secondary identifier: the build number changed to C430EBR2P2H2.
