4G only: Android 11+ Supported is a free utility tool application developed by Haritha Hulangamuwa for Android devices. This app lets you access the hidden RadioInfo settings on your phone, which allows you to switch network mode between LTE only (4G only), WCDMA only (3G only), GSM only (2G only), NR only (5G only), or any combination between them. The app is very lightweight and does not require any app permissions.

One of the best features of this app is that it is completely ad-free, which means you can use it without any interruptions. However, it is important to note that the hidden settings may not be available for every phone. If the settings are not available on your phone, the application will not work. Therefore, it is recommended to install the app and check if it is compatible with your device before using it.

Overall, 4G only: Android 11+ Supported is a useful utility tool for those who want to have more control over their network mode. It is easy to use and does not require any special permissions, making it a great app to have on your device.
