You can do this by navigating to “Settings,” then “Wi-Fi,” tapping on the menu icon, and selecting “Advanced.” There, you will find the option to turn off Smart network switch.
If your device continues to switch networks even when you’ve disabled this feature, it may be worth considering potential issues with Wi-Fi settings or interference. Ensure your Wi-Fi network is stable and that there are no issues with the router, as these could cause the device to attempt to switch to mobile data unnecessarily.
What steps can I take if none of these solutions work?
If you’ve attempted all the previous solutions and are still experiencing mobile data issues on your Samsung Galaxy S4, it may be time to consider doing a factory reset. Before proceeding, make sure to back up your important data, as this process will erase all personal information, apps, and settings. To perform a factory reset, go to “Settings,” select “Backup and reset,” and choose “Factory data reset.”
If a factory reset does not resolve the issue either, it’s advisable to reach out to Samsung support or your mobile carrier for further assistance. They may be able to provide more specific troubleshooting based on your account and network conditions, or in some cases, suggest a hardware check if there are underlying issues with the device itself.
