Galaxy Z Fold 7 Bug Unlocks Powerful Three-App Multitasking

A newly discovered bug in Samsung’s Galaxy Z Fold 7, running One UI 8, allows users to run three apps simultaneously in split-screen mode, surpassing the device’s official two-app limit. This unexpected feature, resembling OnePlus’ Open Canvas, has sparked excitement among foldable phone enthusiasts but comes with quirks that highlight its unofficial status. This concise article details the bug, how to activate it, and its implications for Samsung’s multitasking future, tailored for tech fans eager to explore this powerful glitch.

The Bug: Three-App Multitasking Unlocked

The Galaxy Z Fold 7, powered by One UI 8 and Android 16, typically supports a 90:10 split-screen mode for two apps or two apps plus a floating window. The bug, first spotted by Reddit user u/traneric1 on August 11, 2025, enables three apps to run side by side on the main display. To activate it:

1. Open two apps in 90:10 split-screen mode.
2. Access and immediately exit the Edge Panel settings.
3. Drag a third app from the Edge Panel to the screen.

This confuses the system, allowing a third app to join without displacing the others, creating a layout similar to OnePlus’ Open Canvas.

How It Works and Limitations

The bug exploits a glitch in One UI 8’s multitasking framework, letting three apps share the 8.2-inch display. However, it’s not polished:

• Resizing Issues: Adjusting app windows, especially the bottom two, can cause the top app to lock or glitch visually.
• Inconsistent Controls: Saving app pairs or switching split orientations is unreliable.
• Stability: The feature isn’t optimized, leading to occasional crashes or lag.

Despite these flaws, users on X, like @thatjoshguy69, have called it “hilarious” and “game-changing,” sharing demos of its potential.

Implications for Samsung and Users

• Future Feature?: The bug suggests Samsung is testing a robust three-app multitasking system, potentially for a future One UI update, as it mirrors OnePlus’ praised Open Canvas.
• User Impact: Power users, like professionals juggling email, notes, and browsers, gain productivity, but casual users may find it clunky without refinement.
• Samsung’s Response: The company hasn’t commented, but a patch could remove the bug, or user feedback might prompt its development into a full feature.

Why It Matters

The Galaxy Z Fold 7, with its Snapdragon 8 Elite chip and 8.2-inch AMOLED display, is built for productivity. This bug pushes its multitasking capabilities further, offering a glimpse of what foldables could achieve. As competitors like OnePlus lead in multitasking innovation, Samsung may use this accidental feature to close the gap, enhancing its edge in the foldable market.

The Galaxy Z Fold 7’s three-app multitasking bug is a thrilling, if imperfect, discovery that showcases the device’s potential. While not ready for prime time, it hints at Samsung’s plans for advanced multitasking in future updates. Users can try it for a productivity boost, but expect quirks until Samsung refines or patches it.
