iOS 9 Update Issues: Quick Fix

Here’s a guide on how to fix iOS 9 update issues by reinstalling or reconfiguring iOS 9, which gets rid of most of the minor inconveniences that some of the users have been experiencing. If your device is laggy, prone to freezing or locking up or you simply have the feeling that something went awry with your iPhone when switching to iOS 9, try our troubleshooting guide below.

Recommended first step: iTunes backup

The key to safely reinstalling iOS 9: Create or have a current backup, ideally using iTunes instead of iCloud, at least for this procedure. The advantage of a local backup versus an iCloud backup is the speed at which it can be restored to your device. Downloading all of your personal information and all of your apps can take quite a while, doing this via USB is often much quicker. It all depends on the size of your installation and usage habits. Here’s a guide on how to create a full iPhone backup using iTunes.

Resetting your iPhone and restoring iOS

By deleting all of your personal data and settings, we can start with a blank slate. The great part about the blank slate: You can reimport everything using your backup, as soon as iOS 9 is working as it should.

Open up the “Settings” app on your iPhone. Go to “General” and tap “Reset” at the very bottom, then select the second option, namely “Erase All Content and Settings” to clear your device of any and all potentially erroneous data. Enter your Passcode when prompted. After the cleaning procedure, iOS 9 will reconfigure the defaults and hopefully work as it should.

Now it’s time to fetch your backup and reintegrate it into your current working iOS 9 installation. This is achieved through several means, which we have outlined in a separate guide called “3 ways to restore an iPhone”. Naturally, you will want to go through iTunes due to the aforementioned benefits.
