If your Samsung Galaxy S3 Internet stops working. There are a couple of factors that should be checked. These are your carrier, router settings, Internet connectivity settings of your phone, interference of other apps or main glitch in the system of your device (due to a software update).
To go over the problem, try clearing the browsing data of your Galaxy S3 first. Then, reboot or perform a powercycle (remove the battery while the phone is on and restart it) if the problem continues. If you are still getting the same result, check if your router is working properly (this is if you are using WiFi). But when any of these do not work, call the Customer Support hotline of your carrier to report the issue because your area might be experiencing an intermittent Internet connection.
If the problem is not in the network, then there might be an app that is interfering with the Internet function of your phone. Simply locate the cause and uninstall it if that’s the case. However, once all else fails, reset your device to its factory settings.
