Resetting all of your iPhone's settings may assist, especially if the new update instantly overrides your present settings, resulting in a dispute. Unlike a factory reset, this reset has no effect on your iPhone data, therefore no data is lost.

1. From the Home screen, choose Settings.
2. Select General.
3. Reset may be found by scrolling down and tapping it.
4. Choose Reset All Settings from the drop-down menu.
5. Enter the device passcode if asked.
6. Then, to complete the settings reset, press the choice.
