Google rolled out the final OS update for the Pixel 4 and Pixel 4 XL back in October 2022 with Android 13. A security and bug-fixing update arrived a few months later, but that’s about it. Now, if you are still rocking a Pixel 4, you can experience Android 16 on it, all thanks to the LineageOS team.
