Problem #6: Samsung Galaxy S4 unable to connect to mobile network after display replacement
Hi. I have a Samsung Galaxy S4 Active that loses connection to my mobile network every time I turn on my Wi-Fi, have it on, or if am around any Wi-Fi signal. This all started for days ago after I changed my screen and LCD. The Wi-Fi works perfectly though. Any ideas to my problem? — Jmeadows
Solution: Hi Jmeadows. Please disable your phone’s Smart Network Switch. When this is ON, this feature will try to find the most favorable connection for the device, automatically switching you either to a compatible Wi-Fi or mobile data network. In theory, this advanced setting is designed to preserve consistent internet connection but we know that it doesn’t always work that way. Here are the steps on how to disable it:
- Go to Settings.
- Tap Wi-Fi.
- Tap the menu icon located on the bottom-left hand side of the screen.
- Tap Advanced.
- Tap Smart network switch and turn it OFF.
