NavStar for Android

NavStar replaces the standard navigation layout by letting you swap icons, add extra buttons, and tweak gesture handles and bar transparency in One UI. SE Co Ltd supplies this Good Lock module in the social-communication category, integrating with system settings to change navigation visuals. Key controls include custom icons, up to two added functional buttons, and gesture handle sizing. It fits Samsung Galaxy owners who want deep visual and interaction tweaks on phones and tablets.

NavStar reworks One UI navigation beyond stock limits

NavStar changes how you interact with the navigation bar. The app gives direct control over Back, Home and Recents icons, lets you set pre-made stickers or user images, and permits background color and transparency adjustments. It also shows or hides the navigation bar dynamically. Key capabilities:

• Custom icons and images
• Adds up to two additional functional buttons
• Background color and transparency

System-level integration preserves device configuration without rooting

Developed under Good Lock Labs by Samsung, NavStar integrates at system level with One UI and provides custom ROM-like navigation features without rooting devices. The developer's official module design means users don't need root access to add extra buttons or alter system navigation visuals, and the tool is optimized for One UI to keep system stability while applying visual changes.

Gesture and accessibility controls suit large-screen use

NavStar exposes granular gesture and accessibility settings that target one-handed and large-screen navigation. Controls include gesture handle length, handle color, and sensitivity adjustments, plus options to show or hide the bar dynamically. Community feedback highlights that adding custom buttons and resizing gesture handles makes big displays easier to reach. These controls focus on interaction placement and contrast, letting users adjust visibility and tap targets to match their preferred reach.

Availability is limited to Galaxy devices and requires Good Lock

NavStar is exclusive to Samsung Galaxy devices and needs the Good Lock app or a compatible launcher to function. The module requires Android 8.1 or later, so it cannot run on older devices. It is the official method Samsung provides to add extra functional buttons into the system navigation bar, which keeps integrations tight with One UI but limits availability outside the Galaxy ecosystem.

Targeted choice for customization-focused Galaxy power users

NavStar is a targeted option for Samsung Galaxy power users who want system-level navigation control; its integration with Good Lock and One UI gives stable, official customization. Consideration: it runs only on devices with Android 8.1 or higher, so older hardware can't install the module. Choose NavStar if you prioritize deep, per-device navigation customization over cross-device portability.
