MultiStar forces active multi-window multitasking on Samsung Galaxy
Forces apps into active multi-window modes, keeping both windows running and adding a swipe-to-pop-up floating window gesture. Made by Samsung Electronics Co., Ltd., this Good Lock module extends Android window management on Galaxy devices. Key controls include forced multi-window support, multi-window without pausing, screen zoom for split views, and DeX enhancements for external displays. It targets Galaxy power users, productivity-focused tablet and foldable owners who need tighter control of app behavior in split and pop-up modes.
How MultiStar changes everyday multitasking
MultiStar forces apps that normally refuse split-screen into multi-window mode and keeps both apps active, which alters the default Android pause behavior. The module provides a pop-up view action, activated by swiping from the top corners, and a multi-window screen zoom to increase usable content area in each pane. These controls let power users run concurrent tasks without the usual background-pausing constraint imposed by many apps.
How it integrates with foldables and external displays
The module includes foldable-specific options labelled "I Galaxy Foldable" and adds a Launcher Widget for cover screens on Flip devices, reflecting features tailored to Z Fold and Z Flip hardware. MultiStar also enhances Samsung DeX output with higher-resolution support for external monitors, which moves a phone or tablet toward a desktop-like session when connected to an external display.
Platform limits and deployment requirements
MultiStar is exclusive to Samsung Galaxy devices running One UI on Android 8.1 or higher and is distributed through Good Lock, so it cannot run on generic Android phones. Optimal behavior is noted on devices supporting One UI 5.0 and above. Because it operates inside the One UI customization framework, its availability and behavior depend on the device’s system version and the Good Lock installation state.
Who should enable MultiStar on their Galaxy device
MultiStar is a functional option for Galaxy power users and foldable owners who need active, forced multi-window sessions and DeX improvements. Expect a module that depends on One UI and Good Lock for installation and device-level compatibility. Consider it when you need persistent simultaneous app activity or cover-screen widgets; casual users who rely on stock Android window behavior may find its scope unnecessary.
