Device: OnePlus One, non-rooted, stock Cyanogen OS

I installed an OTA update today (27 August 2016).

Now, the Android security patch level shows a date from the future (1 September 2016).

Why is it such a date?

    Google sends out the security patches for the next month a few weeks earlier, so manufacturers/carriers can implement them and test them before releasing an OTA in a timely fashion.

    @GiantTree If you are sure, do post an answer. :)

  • I think @GiantTree has the point, but nevertheless, there's a small possibility that it's modified in build.prop to display that. Patch note is not released yet so no way to verify.

GiantTree's explanation sounds plausible but there is a bug report raised on first of this month for a patch released last month with similar concern : Issue 218947: Security Patch Level shows the future date?

There has been no revert on this from Google, so the cause is uncertain. OP may star the bug report to be updated by Google
