Learn how to force 4G LTE only on Samsung phone without root. All Android phones have an option to enable 4G LTE only, however, due to the network coverage limitation, some telco has to disable this.

The reason is simple, when you’re not in 4G LTE area, you’ll not be able to call or receive a call if you force 4G LTE only network. Here’s the basic option on all Android phones:

  • LTE/WCDMA/GSM auto — the phone will automatically select the best network in your area between 4G LTE, WCDMA, and GSM
  • WCDMA/GSM auto — the phone will automatically select the best network in your area between WCDMA and GSM
  • WCDMA only — the phone will be using WCDMA network only regardless it is available or not, if not, you will not have any signal
  • GSM only — the phone will be using GSM network only, this is the most common network, no need to worry, you will have full signal

Basically, the app that we’ll be using works on majority Android phone. All you need to do is download this app and enable 4G LTE Only. This app is called 4G LTE Switcher. Find the download link below.
