Update your phones and iPad immediately.
Starting just before 12:00 am UTC (approx. 4am UAE time) on November 3, 2019, some iPhone and iPad models introduced in 2012 and earlier will require an iOS update to maintain accurate GPS location and keep the correct date and time. This is due to the GPS time rollover issue that began affecting GPS-enabled products from other manufacturers on April 6, 2019. Affected Apple devices are not impacted until just before 12:00am UTC on November 3, 2019.
In addition, devices that aren't updated before November 3, 2019 might not be able to receive over-the-air software updates. As a result, the only way to update the device will be to restore in iTunes or Finder via tethered connection.
