4G LTE Mode Only is a mobile application developed by AlphaBrain Apps Studio that helps users optimize their network settings. This app allows users to switch their network to "4G LTE mode only" and examine the channels and networks of WIFI. It also lets users access advanced network settings and change network parameters.

One of the most useful features of this app is the ability to lock the phone in 3G and 4G only stable network signals or on any specific network signal such as 4G Only and 3G. In addition, it enables Volte permission on supported devices, which allows direct calls via the 4G network. The app also offers a 4G Switcher Log Notification to open all hidden settings menus to select advanced network settings.

Moreover, the app provides users with a video tester that plays a 15-second video clip to record load time, buffering time, and playback speed in actual time to show the exact result of HD and SD video from their network. It also lets users test their internet speed at 5G network speed and check the strength of their cellular signal at 4G network speed.

Overall, 4G LTE Mode Only is an efficient and easy-to-use app that helps users adjust their network settings to optimize their mobile experience.
