Google calendar force closing after OTA update (SM-G930A) I have a G930A, un-rooted, running AT&amp;T's version of Oreo (8.0.0). I received an OTA update over the weekend and cannot use Google Calendar since--app force stops.

I also cannot do a calendar insertion from Tasker.

I have, of course reinstalled, cleared system cache, twiddled permissions, even factory reset, but am getting nowhere. Wife's phone has same update, but calendar is working fine.

Baseband G930AUCS8CRK1

Build R16NW.G930AUCS8CRK1

Security patch level November 1, 2018

Any thoughts?
Ended-up flashing the old firmware (links on xda) and redoing the OTA upgrade. Worked fine this time, which makes me think the first OTA file was munged. Doesn't AT&amp;The have any error-checking built-in to their upgrade script?!
