iOS 11 brings several breakthroughs, including a more intelligent Siri with translation, a highly-customized Control Center, a new App Store, and a File app for iOS document management. However, many users have reported problems after updating to iOS 11, such as alarm not working, notification, Bluetooth, and flashlight issues on iPhone 6/6S/7/7 Plus. Another issue affecting many users is Safari not working in iOS 11 on iPhone and iPad, and the following solutions are provided to help troubleshoot this problem.
When Safari isn't working, check the network settings first. Go to Settings > Cellular > Safari, and ensure WLAN & Cellular Data are enabled. If that's not the issue, try the following troubleshooting steps.
If the Safari app is stuck with no response, but other apps work well, you can try relaunching the Safari app to solve the problem. To do this, double-click the Home button on your device screen to activate the multitasking screen, then swipe up the Safari app to close it. Wait for 30 seconds, then re-open Safari. If this doesn't work, you can try other troubleshooting methods.
If multiple apps, including Safari, aren't working well, check the network connection. If it's unstable or not well connected, try switching to a different network and reopen Safari to see if it resolves the issue.
Resetting network settings in iOS 11 can resolve Safari issues caused by incorrect network settings. This process will remove all Wi-Fi information, including account and password, so you'll need to re-enter your Wi-Fi password afterwards.
To reset network settings, go to Settings, then General, then Reset, and finally select Reset Network Settings.
If your iOS 11 Safari is running slowly, you can improve its performance by cleaning cache, history, and website data, which can help resolve the issue.
To clear Safari history and website data on your iPhone, go to Settings > Safari > Clear History and Website Data. This will remove browsing history, login data, theme selection, preferences, and other customized information, but will not affect your bookmarks. If your iPhone is running slowly, clearing Safari history and website data may help resolve the issue.
After updating to iOS 11, if you've enabled the restriction for the Safari app, it won't work normally. To fix this, go to your phone's "Settings", then "General", followed by "Restrictions", and enter your password. From there, toggle off the Safari restriction if it's enabled.
Restarting your iPhone can fix many small issues, including Safari not working in iOS 11. To do this, press and hold the Sleep/Wake button until you see "slide to power off" and swipe right to turn it off. Wait 30 seconds, then re-open your iPhone again. This will close all processes and release iOS memory, potentially resolving the issue.
If Safari not working in iOS 11 is due to system bugs, updating to the latest iOS version can resolve the issue.
To update your device, go to Settings, then General, followed by Software Update, and check if there is a new version available. If so, download and install it.
