Apple's suppliers only made a few hundred iPhone Ultra units per day in August

Mass production of the iPhone Ultra has been underway for at least some weeks, but quality control inspections are reportedly rejecting all but a few.
The expected iPhone Ultra is still believed to be announced at the September 9 event, but supplies may be extremely constrained.
Reports have varied for months over whether the iPhone Ultra is delayed because of manufacturing problems, or whether those have been resolved. Now according to Nikkei Asia, however, production has been very slow.Reporte
