What Custom Phone Gestures Are and Why They Matter
Custom phone gestures are personalized swipe actions you assign to the edges of your screen so common tasks, apps, and tools are triggered from your thumb’s natural resting area instead of relying on fixed system buttons or default navigation gestures.
On larger Samsung phones, standard navigation can feel like a thumb workout: reaching the notification shade, taking screenshots, or opening split screen often means shifting your grip or using a second hand. Custom phone gestures solve that by turning the sides of your display into screen edge shortcuts that match how you already use your phone. With Good Lock settings, you can place invisible handles along both edges, then map different swipe directions and lengths to the actions you care about most, from screenshots and flashlight to split screen and quick tools panels. If you often repeat the same gestures all day, building your own edge controls can make your phone feel faster without upgrading its hardware.
Prerequisites: What You Need Before You Start
Before you try to replace your default controls with edge‑based gestures, there are a couple of important caveats. First, custom phone gestures in this guide rely on Samsung’s Good Lock suite. Good Lock does not come preinstalled; you have to download it from the Galaxy Store, then install its modules from inside the app. Second, Good Lock only runs on devices with the full version of One UI, while many budget A and M series phones ship with One UI Core, which does not support these modules. If your phone uses One UI Core, you will need to look for third‑party gesture apps instead of Good Lock.
If you are on full One UI, you will use two pieces: One Hand Operation+ for Samsung edge controls and screen edge shortcuts, and NavStar for fine‑tuning navigation gestures. One Hand Operation+ lives inside Good Lock and lets you place invisible handles on the sides of your screen. NavStar is another plugin that adds deeper control over back gesture sensitivity than the built‑in settings provide, including separate sliders for left and right edges. Having these installed is your real prerequisite before you start rebuilding your gestures.
Step-by-Step: Build Your Edge-Based Gesture System
Think of this section as setting up a control center under your thumb. We’ll walk through one sequence that takes you from default gestures to a full set of custom phone gestures using Samsung edge controls, plus some fine‑tuning so they behave the way you expect.
- Install Good Lock from the Galaxy Store, open it, and download the One Hand Operation+ module from inside the app.
- Open One Hand Operation+ and enable the left and right edge handles so both sides of your screen are active for gestures.
- In the handle settings, assign actions to the three swipe directions for each handle (straight, diagonal up, diagonal down) and set short vs. long swipes for up to twelve gesture slots.
- Turn on long swipes in the Gesture settings to unlock the full twelve actions; this doubles your available slots compared to short swipes alone.
- Enable the Quick action option so long-swipe actions trigger as soon as your thumb crosses the distance threshold instead of waiting for you to lift your finger.
- Map everyday tasks to these screen edge shortcuts, such as screenshots, notification panel, Quick Settings, flashlight, and split screen, focusing on what your thumb naturally reaches.
- Install the NavStar plugin from Good Lock, open it, and toggle it on, then scroll to Back gesture sensitivity to adjust left and right edges independently.
- Reduce the sensitivity of the right-side back gesture to the lowest level while leaving the left side at your preferred setting so accidental back swipes are less likely.
The real gotcha in this process is forgetting about long swipes and Quick action. When you first install One Hand Operation+, long swipes are switched off, so each handle only responds to short swipes and you end up with six gesture slots. Turning on long swipes and Quick action effectively unlocks a second layer for each direction, making those same edges feel like a compact control grid. Another common mistake is leaving the back gesture sensitivity untouched. Because Android’s back gesture works from both edges, it is easy to trigger by accident when you swipe near the sides. NavStar fixes that by letting you make one edge far less sensitive so it only reacts when you want to go back.
Power Up Your Screen Edges With Shortcuts and Panels
Once your basic gestures are in place, you can treat the edges of your display as launch pads rather than simple navigation zones. Each One Hand Operation+ handle responds to three directions and two swipe lengths, giving you twelve potential actions without adding visible buttons to the screen. A short diagonal swipe from the right can take a screenshot, a long diagonal swipe from the left can open the notification panel, and another short swipe near it can jump straight to Quick Settings. Mapping the flashlight to a long straight swipe makes it feel like a physical switch at the side of your phone.
You can also plug in more advanced tools and third‑party panels. Quick Tools opens a floating control center with brightness and volume sliders, media controls, and toggles for Wi‑Fi, Bluetooth, flashlight, and screen recording, all from a single edge swipe instead of dragging down from the top of the screen. Task Switcher and Quick Launcher follow the same idea: one pulls up a floating list of recent apps with search, the other shows a pinned grid of apps you can open without going home. One quotable result from this kind of setup is that split screen goes from a four‑step process to “a single diagonal swipe” located exactly under your thumb.
What You Gain and What to Watch For
When you finish this, your phone stops feeling like it was designed around generic defaults and starts feeling like it was built for your workflow. According to one user source, jumping between recent apps with navigation gestures became much faster once they adopted the gesture bar and got used to swiping left or right along it. Likewise, reorganizing common actions into screen edge shortcuts cuts repeated four‑step routines down to single swipes where your thumb naturally rests. Custom gestures also remove much of the learning curve: instead of adapting to fixed system behavior, you arrange gestures to match what your brain expects, whether that is a diagonal swipe for multitasking or a straight pull for tools.
The main thing to watch for is accidental gestures. If you ignore back gesture sensitivity, you can trigger unintended back actions when swiping near the sides, especially when flicking through photos or call logs. Fine‑tuning the left and right sensitivity with NavStar so one side is less reactive solves most of this. It is also worth remembering that Good Lock modules, including One Hand Operation+, do not support One UI Core devices. If your phone qualifies, though, the payoff is clear: your Samsung edge controls evolve into a flexible control center, and everyday navigation feels measurably faster and more natural.
