LG G6 Rounded Display on Any Android

This guide shows you how to get the distinctive rounded-corner look of the LG G6’s display on virtually any Android phone. You won’t need root access or a custom ROM—just a free app that overlays a subtle, transparent mask on your screen. The result is a softer, more modern edge that mimics the G6’s signature design, and you can turn it off in seconds if you change your mind.

What You’ll Need

An Android phone running Android 5.0 (Lollipop) or newer—most devices from 2015 onward qualify.
Permission to install apps from unknown sources (if you’re not using the Google Play Store).
About 10 MB of free storage space.

Step-by-Step

Install a screen overlay app. The most reliable and widely used option is Round Corners (by developer jagan2). Open the Google Play Store, search for “Round Corners,” and install the app by jagan2. There are similar apps like “Cornerfly” or “Rounded Corner,” but the steps below focus on Round Corners because it’s free, ad-free, and actively maintained.
Open the app. Tap the Round Corners icon in your app drawer. You’ll see a simple interface with a slider and a toggle switch at the top.
Enable the overlay. Toggle the switch at the top of the screen to “On.” The app will immediately draw rounded corners on top of your display. You’ll see the corners of your screen become softly curved, just like the LG G6.
Adjust the corner radius. Use the slider to set the radius. The LG G6 uses a radius of about 5–7 pixels on a 1440p display, but on a typical 1080p phone, a value between 15 and 25 pixels looks closest to the original. Start at 20 and adjust until it looks right to you. The preview updates live, so you can see the effect as you drag.
Set the corner color. Tap the color swatch (usually a black square) to choose the color of the rounded mask. Black is the default and works best on OLED screens (like Samsung AMOLED) because the mask blends with the bezel. On LCD screens, choose a color that matches your phone’s bezel—often black or dark gray.
Fine-tune the corner style. In the app’s settings (tap the gear icon), you can enable “Full screen corners” to apply the effect to all apps, including full-screen games and videos. You can also adjust the “Corner size” independently for each corner if your phone has an asymmetric bezel (like some Sony or older LG models).
Test in different apps. Open your home screen, a browser, and a video player. The corners should appear consistently. If you notice the mask interfering with touch input (rare), go back to the app and reduce the radius slightly.
Set the app to start on boot. In the app’s settings, enable “Start on boot” so you don’t have to re-enable it after a restart. On some phones, you may also need to disable battery optimization for the app to keep it running in the background. Go to Settings > Apps > Round Corners > Battery and select “Unrestricted” (or “Don’t optimize”).
Remove the effect. To turn it off, simply open the app and toggle the switch to “Off.” The corners will disappear instantly, and your display returns to its normal shape.

Common Mistakes

Setting the radius too large. A radius above 40 pixels on a 1080p screen will start cutting into notification icons and text. Keep it under 30 for readability.
Using the wrong color on LCD screens. If you pick pure black on an LCD phone, the corners may look slightly gray or pixelated because LCDs can’t produce true black. Match the mask color to your bezel instead.
Forgetting to allow overlay permission. On Android 6.0 and newer, the app needs “Display over other apps” permission. If the corners don’t appear, go to Settings > Apps > Round Corners > Display over other apps and enable it.
Using a launcher that draws its own corners. Some launchers (like Nova with certain themes) already add rounded corners. Disable that feature in the launcher settings to avoid a double-rounded, blurry edge.

Tips

Combine with a rounded wallpaper. For the most authentic LG G6 look, use a wallpaper that has dark or black edges. The overlay will blend seamlessly with the wallpaper’s dark areas.
Use a different radius for landscape. In the app’s settings, you can set a separate radius for landscape mode. A slightly larger radius (25–30) looks better when watching videos because the corners are more visible on a wide screen.
Reduce battery drain. The overlay is drawn by the GPU, which uses a tiny amount of battery. To minimize it, avoid using a very large radius and keep the app updated to the latest version, as newer builds are more efficient.
Pair with a gesture navigation bar. If you’re using gesture navigation (swipe from the bottom), the rounded corners will complement the gesture bar’s curve nicely—similar to the G6’s design.

Troubleshooting

Corners don’t appear at all. First, check that the toggle is on. Then, verify the overlay permission is granted. On Samsung phones, go to Settings > Apps > Round Corners > “Allow display over other apps”. On Xiaomi or Huawei, you may need to enable “Float window” permission separately.
Corners disappear after a few seconds. This usually happens because the app is being killed by aggressive battery optimization. Add the app to the “Unrestricted” or “No restrictions” battery list in your phone’s settings. Also, lock the app in your recent apps (tap the app’s icon in the recents view and select “Lock”).
The corners look jagged or pixelated. Lower the radius slightly. Very high radius values on low-resolution screens can cause aliasing. Also, ensure your screen resolution is set to the native resolution, not a lower power-saving mode.
The overlay blocks touches near the corners. Reduce the radius. If the problem persists, check if the app has a “Touch passthrough” option in its settings—if so, enable it. If not, try a different app like Cornerfly, which handles touch differently.
The effect doesn’t show in screenshots. That’s normal—screenshots capture the underlying content, not the overlay. To show someone what it looks like, take a photo of your screen with another phone.

Frequently Asked Questions

Will this damage my screen?

No. The app only draws a visual mask over the display; it doesn’t alter the hardware or the touch digitizer. It’s purely cosmetic and reversible.

Does it work on any Android version?

It works on Android 5.0 and newer. On Android 12 and 13, the app still functions, but you may need to grant “Display over other apps” permission again after a system update.

Can I have different corner sizes for each corner?

Yes. In the app’s settings, there’s an option to adjust each corner individually. This is useful if your phone has a notch or a chin that makes one corner look different.

Will this affect my battery life?

Minimally. The overlay is drawn by the GPU, which consumes a negligible amount of power. Most users report less than 1% extra battery drain per day.

Is there a way to get the LG G6’s exact look?

Yes—set the radius to about 20 pixels on a 1080p screen, use a black mask, and enable “Full screen corners.” You’ll get a very close match to the G6’s 5.7-inch 18:9 display with its subtle rounded edges.

Does this work on tablets?

Yes, it works on any Android device, including tablets. However, on larger screens, you may want to increase the radius to 30–40 pixels to make the effect visible.

General steps for current mainstream versions; menus can differ by device and version. See the disclaimer or report an error.
