Suddenly, no call log history on Iphone 6. Shows only ONE "recent" call from May 15, 2018. Nothing else there.
No records in "missed." Nothing there.
Iphone storage is 13.6 GB of available 64GB, so that's not the problem.
Did three hard restarts. Did not solve.
Upgraded to Apple IOS 11.3.1. Did not solve.
