4G Only

4G Only is a lightweight Android app that quickly opens the hidden Phone Information screen, letting you set LTE-only (4G only) or NR-only (5G only) modes. It doesn’t change radio settings directly—just gives fast access. Features a simple Material UI, clear instructions, and handles blocked or missing pages gracefully.HighlightsLaunches the system Phone Information/RadioInfo screen directlySimple UI: About, Instructions, and Set 4G OnlyMaterial 3 styling with ConstraintLayoutHow it worksThe app does not change the radio settings itself. Instead, it opens the Android internal Phone Information (RadioInfo) activity if present on the device. From there, you can select the preferred network type (e.g., LTE only). Availability depends on OEM/ROM and Android version.
