There is a lot that can be customized on an iPhone, and often it’s difficult to find the options you’re looking for within the maze of sub-menus in the Settings app.
Luckily, from iOS 9 onwards Apple has added the ability to search through these options. Simply open the Settings app and scroll upwards to reveal a search bar. Type in what you’re looking for to save yourself some time and hassle.
No more frustration trying to turn off Shake to Undo or remember where the Time Zone settings are kept!
