Many iOS related issue can be resolved by resetting your device. The Reset (or Force Restart) can fix issues that a soft restart (using the power off slider) will not. Although the process is called "resetting", you should not lose any data from the device, nor will you lose any settings.
If you're having trouble with your iPad or iPhone, try this process to reset it:
- Hold both the Power and Home buttons until the screen goes black and then you see the white Apple logo.
(If you first see the red slider alert
to power off, ignore that and keep
holding both buttons)
