Samsung Galaxy S4: Disable 4G/LTE

I own a Verizon Samsung Galaxy S4 and wanted to disable 4G/LTE to save battery power. I couldn’t find a setting, but there is a way.

While some versions of the S4 allow you to go to Settings > More networks > Mobile networks > Network mode > CDMA to disable 4G and allow a 3G only connection, the Verizon version does not. I searched Google Play for a free app that disables 4G, but couldn’t find one that actually worked with my phone.

Finally I tried 4G Switch for 99 cents and it’s the only app I’ve found that actually works for disabling 4G/LTE.

1. Download 4G Switch from Google Play.

2. Once installed, open the app by tapping Apps >4G Switch.

3. Tap Start.

4. Select Phone information.

5. Select GSM/CDMA auto (PRL) for the preferred network type setting.

Your S4 will now connect via a 3G only connection and LTE will be turned off.

    Excellent app. I was having issues with my S4 dropping calls even with the network extender. With this app I am able to turn off 4G and I am getting full bars and no more dropped calls.

    Yep! This is the only thing that worked for me too! Well worth the dollar for the app.
