An iPhone 12 is a great device, but occasionally, you may run into problems with it. However, a problem with your iPhone 12 doesn’t have to mean a trip to the nearest Apple Store or a phone call to tech support. You can solve most iPhone 12 problems by following a few troubleshooting tips.
Causes of iPhone 12 Issues
When an iPhone 12 has a problem, it could have a few root causes. Apps can interfere with one another or with the iPhone’s operating system. These malfunctions can affect the device’s resource management or corrupt parts of its memory. The phone might also have network issues that cause trouble connecting to the internet.
How to Fix Problems With Your iPhone 12
Follow these troubleshooting steps to determine the problem with your iPhone 12 and find a fix.
The iPhone keeps apps open—most in a suspended state—even if you aren’t using them. So if you notice some sluggishness, closing resource-hogging programs might solve the issue. Open the App Switcher by dragging a finger from the bottom to the middle of the screen. Close apps by dragging their windows toward the top and off the screen.
Delete troublemaking apps
If you can track your iPhone 12 problems to a single app that is either incompatible with others or possibly corrupted, delete it. On the Home screen, hold a finger on the app until all of the apps start to shake. Tap the X in the upper-left corner of the icon to delete the app.
Apps can become corrupted. After you’ve deleted one, download it again from the App Store to see if it works better after you reinstall it.
Deleting an app also removes its data, so back it up if possible before you uninstall it.
Reboot the iPhone
If you have a problem with an app and closing it doesn’t fix the issue, or if you experience another type of problem, reboot the iPhone. Turning the iPhone off and back on clears the available memory and gives the iPhone a fresh start. Hold down the power button and volume up button to bring up the slider that lets you power off the iPhone. Once it is powered down, press the side button again to turn the iPhone back on.
Do a hard reset
If your specific issue causes your iPhone 12 to freeze, the reboot may not work. Do a hard restart by pressing the volume up followed by volume down and then holding down the side button for a few seconds until the iPhone shuts down. Release the buttons when the Apple logo appears on the display.
Check your network
You may have problems connecting your iPhone 12 to the internet. These issues may or may not be coming from the iPhone. If possible, do a speed test to see if your wireless connection is working and strong enough. If it isn’t, move closer to your router or reset your Wi-Fi hardware. Start by unplugging your router and modem (if they’re separate), and then wait 30 seconds and plug them back in. You can also reset your iPhone’s network settings by going to settings > general > reset > reset network settings.
Reset your iPhone
This step is different and more intensive than a restart; it involves deleting everything on your iPhone and then reinstalling it. Before you do this, back up your iPhone to make sure you don’t lose your photos or contacts. To reset your iPhone to factory, go to settings > general > reset > erase all content and settings.
Ask for help
If none of these steps work, you might need to take your iPhone to an Apple Store Genius or authorized service center for servicing. Before contacting Apple Support, you may want to check if your iPhone is still under warranty. The standard Apple warranty grants 90 days of technical support and a year of limited hardware protection. The AppleCare program gives two years of both technical and hardware support. Call Apple support at 1-800-676-2775.
