How to Trou­bleshoot your iOS is­sues

Mac|Life - - FEATURE -

Find the app

If an app causes prob­lems and is open, close it and open it again. If it’s un­re­spon­sive, force it to quit. Dou­bleclick the Home but­ton (or swipe up from the bot­tom and hold a sec­ond on iPhone X) to open the app switcher.

Back up to iCloud

Be­fore try­ing any­thing else, make a backup of your de­vice. To do so us­ing iCloud, con­nect to Wi-Fi, then go to Set­tings > [your name] > iCloud > iCloud Backup and en­able this fea­ture. Start a man­ual backup and let it fin­ish.

Re­in­stall the app

In the App Store, tap To­day in the bot­tom bar, then your pro­file im­age at the top of the page, and then Pur­chased. Tap Not on this iPhone/ iPad, lo­cate the app in the list of past pur­chases, and tap the down­load icon.

Force quit

Swipe hor­i­zon­tally to find the app, then swipe up­wards on its pre­view to force the app to quit. On iPhone X, hold your fin­ger on an app’s thumb­nail un­til red mi­nus but­tons ap­pear, then swipe up on the one you want to quit.

Back up to iTunes

To back up us­ing iTunes in­stead, open iTunes on your Mac, con­nect your de­vice, click its icon at the top left, then click Back Up Now. Once the backup is com­plete, eject the de­vice and then disconnect it from your Mac.

Re­set set­tings

Turn off Find My iPhone/iPad in Set­tings > [your name] > iCloud. If you have a Watch, un­pair it now. Be­fore try­ing a full fac­tory re­set, con­sider us­ing Set­tings > Gen­eral > Re­set > Re­set All Set­tings as your next step.

Shut down

If restart­ing the app doesn’t fix the prob­lem, shut down your de­vice by hold­ing the Sleep/Wake but­ton and us­ing the slider to turn it off. Once it has shut down, start it as nor­mal and check for up­dates in the App Store.

Re­move the app

Try iOS 11’s abil­ity to man­u­ally off­load apps, which deletes the app from your de­vice, not its data. If that doesn’t work, hold a fin­ger on the app’s Home screen icon till it jig­gles, tap the X that ap­pears on it, then tap Delete.

Erase and re­store

Re­set your de­vice in Set­tings > Gen­eral > Re­set > Erase All Con­tent and Set­tings. Re­in­stall the app and see if it works. If it does, re­set again, re­store from your backup and try again. If the is­sue re­turns, con­tact the de­vel­oper.
