This guide explains how to enable apps to use full screen on Galaxy S10 and larger Galaxy S10+. These phones have big and beautiful screens with a cutout at the top for the front camera. And while most apps use the entire screen, some have black bars at the top and bottom. Or in landscape mode, the bars on both sides as you can see on YouTube.
Fortunately, you can easily zoom in and out on YouTube to use the entire 6.4-inch screen on your Galaxy S10+ while watching videos. Next, Samsung has a “full screen mode” where you can switch between certain apps that don’t work right in the settings and that’s it.
How to Enable Fullscreen Apps on Galaxy S10
- bring down the notification bar and go to (the gear-shaped icon in the top right)
- find and select
- Scroll down and tap on
- Find the app you want to change and tap on it, then
Any app you notice not using full screen is probably set to auto and the phone doesn’t recognize it or the developer needs to update their app. That said, simply tap on any app that’s giving you trouble and force it into fullscreen mode; You must be good.
Most apps work just fine, as this isn’t the first year Samsung has used these larger, tall, tall but skinny screens. This is the 3rd year Samsung has introduced this type of design. However, we still had to force Snapchat, Clash Royale and a few other games to fullscreen mode.
You should do it?
Whether you force apps to use the whole screen is up to you. Personally, only a few apps had issues and when I replaced them everything was fine. Note that if the app is really old or outdated, some features of the app or interface may be cut off when you go full screen. If so, just revert to the old setting.
Then, most videos have some sort of manual full-screen toggle mode. To use full screen with YouTube, just zoom in and Netflix has something similar you can change.
If our tip does not solve your problem, you can always contact the developer from the Google Play Store. Before you go, take a look at these common Galaxy S10 problems and how to fix them
