You just dropped nearly two grand on a foldable phone. It's beautiful. That massive inner display is supposed to be the future of mobile entertainment, yet the second you open a video, you're greeted by those massive, soul-crushing voids of empty space. Honestly, seeing the s8 fold youtube remove black bars and stretch screen struggle is one of the most frustrating rites of passage for new foldable owners. You want that immersive, edge-to-edge experience you were promised in the marketing renders, but instead, you're looking at a 16:9 box sitting inside a nearly square frame. It feels wasteful.
The Samsung Galaxy Z Fold series (and yes, we're looking ahead at the iterative refinements of the S-line integration) has always wrestled with aspect ratios. Most YouTube content is filmed in 16:9 or 21:9. The Fold's inner screen is closer to a 4:3 or 22.5:18 ratio. Mathematics is a cruel mistress here; you can't fit a wide rectangle into a square without either leaving gaps or cutting things off.
But you didn't buy a foldable to watch a tiny window. You want the screen filled.
The "Pinch to Zoom" Reality
The most immediate way to handle the s8 fold youtube remove black bars and stretch screen issue is the simplest: the pinch-to-zoom gesture. While you're in full-screen mode on the YouTube app, you literally just use two fingers to stretch the video outward.
It works. Mostly.
Samsung’s software is smart enough to recognize when you're trying to fill that "Letterboxing" (the bars on top and bottom) or "Pillarboxing" (the bars on the sides). When you stretch a standard YouTube video to fit the Fold's inner display, the app essentially crops the edges of the video to fill the vertical space.
Here is the trade-off. If you're watching a cinematic trailer, you might lose the tops of people's heads or the subtitles at the bottom. It’s a game of compromises. You're trading "the director's vision" for "using every pixel I paid for." Most people choose the pixels.
Forcing Apps to Behave via Labs
Sometimes the YouTube app feels stubborn. If the pinch-to-zoom isn't triggering, or if the UI elements are overlapping in weird ways, you have to dive into the Samsung "Labs" settings. This is where the real tinkering happens. Samsung knows their screen ratio is weird, so they gave us a backdoor to force apps into submission.
Navigate to Settings, then Advanced Features, and look for Labs. Inside, you'll find an option for Customize App Aspect Ratios. Find YouTube in that list. Usually, it's set to "App Default." Switch that to Full Screen.
This doesn't magically change the video's recorded dimensions, but it forces the YouTube interface to stretch to the absolute boundaries of the hinge and the outer bezel. It makes the transition to "Zoom to Fill" much smoother.
The Mystery of the Black Bars
Why are they even there? It’s not a bug. It’s actually the software being "correct."

Content creators on YouTube mostly upload in 1920x1080 or 3840x2160. These are wide formats. The Fold is tall and wide simultaneously. When you see black bars, you’re seeing the empty space where the video simply doesn't exist.
If YouTube "stretched" the image without cropping it, everyone would look seven feet tall and incredibly thin. It would look like a funhouse mirror. That’s why the "stretch" usually implies "zoom." You're magnifying the center of the image until the edges hit the sides of your screen.
Third-Party Solutions and Vanced Alternatives
Some power users get tired of the official app's limitations. In the past, apps like YouTube Vanced or its modern successors offered more granular control over forced aspect ratios. While the legality and safety of these can be a grey area, the enthusiast community often prefers them because they can "force" a stretch that ignores the crop-factor.
However, for most users, sticking to the official app is better for security. If your s8 fold youtube remove black bars and stretch screen quest feels stuck, check your system updates. Samsung frequently pushes "One UI" updates that specifically improve how the video player handles the "Under Display Camera" (UDC) area. Sometimes, the black bars are actually padded slightly more just to hide that camera hole, which is a choice you can occasionally override in the display settings under "Camera Cutout."
Real-World Usage: Cinematic vs. Creator Content
If you're watching a MKBHD video or a MrBeast vlog, zooming in is fine. Their framing is usually loose enough that losing 10% of the top and bottom doesn't ruin the experience. You get that "wow" factor of a massive screen.
But try watching a movie like Dune or The Batman. Directors like Denis Villeneuve use every inch of that wide frame. If you stretch and zoom on a Fold, you might lose a character standing on the far left of the shot. In these cases, those black bars are actually your friend. They ensure you're seeing everything.

How to Optimize Your Fold for Media
- Enable Video Brightness: Go to Settings > Advanced Features > Video Brightness and set it to "Bright." Select YouTube. This makes the colors pop so much that the black bars (which stay true black thanks to the OLED tech) tend to disappear into the bezel in a dark room.
- Check Your Resolution: Stretching a 1080p video onto a Fold's massive inner screen can make it look fuzzy. Always manually bump your YouTube settings to 2160p (4K) if available, even if your screen isn't 4K. The higher bitrate makes the "zoom to fill" look much sharper.
- Flex Mode: Don't forget that half-folding the phone (Flex Mode) changes the YouTube UI entirely. It puts the video on the top half and the comments/controls on the bottom. In this mode, the black bars are inevitable because the "screen" is effectively halved, but it's a great way to watch while eating or working.
Actionable Next Steps
To get the most out of your display right now, follow these steps:
- Open YouTube and start any video.
- Pinch outward with two fingers. If it says "Zoomed to fill," you've succeeded.
- If it doesn't work, go to Settings > Display > Full Screen Apps and ensure YouTube isn't being restricted.
- Turn off "Portrait Orientation Lock." Some stretch features only trigger when the phone senses it's in a specific landscape orientation.
- Experiment with the "Cover Screen" versus the "Main Screen." Sometimes the aspect ratio settings don't carry over between the two, and you have to set them individually while the phone is open or closed.
The "black bar" problem isn't going away as long as TVs are wide and foldables are square. But by mastering the pinch-to-zoom and the Labs aspect ratio settings, you can at least make sure you're using the hardware you paid for.
