On its support page, Apple has requested users to update their old iOS devices to the latest version before November 3, 2019. The company says, “Just before 12:00 pm UTC on November 3, 2019, some iPhone and iPad models were introduced in 2012 and earlier iOS updates to maintain accurate GPS location and keep the correct date and time. Will be required. This is due to the GPS time rollover issue that started affecting GPS-enabled products from other manufacturers from April 6, 2019. Affected Apple devices are not affected until just before 12:00 am UTC on November 3, 2019. ”
It is advisable to update your device as soon as possible as Apple’s support page states that after November 3, 2019, the device may not receive an over-the-air software update.
If you want to check the software version of your iOS device, you can open the Settings app, tap General, then tap About. See the number next to the software version. The updated software version number should be 10.3.4 or 9.3.6 depending on your device.

IPhone 4s, iPad mini (1st generation) Wi-Fi + Cellular, iPad 2 Wi-Fi + Cellular (CDMA models only) and iPad (3rd generation) Wi-Fi + Cellular should be on iOS 9.3.6. Apple says that this problem does not affect the iPod Touch or any iPad model that only has Wi-Fi. It also does not affect newer iOS devices than those listed above.
