I’ve played around with most Good Lock modules, and while they’re all good, a few stand out as truly exceptional. Some of these modules have even completely transformed how I use my phone, making me wish I had discovered them sooner.
1One Hand Operation+
Having used Android’s gesture navigation for years, I’ve become quite fond of it. The One Hand Operation+ module inGood Lockallows me to add even more of these to my Samsung phone.
With it, I can set up three different swipe gestures on the left and right edges of the screen: swipe out and up, swipe out and down, and the regular straight swipe. On my phone, I’ve configured these swipes to perform tasks like taking a screenshot, switching to the previous app, and turning off the screen.

What’s more, I can set up these same gestures to perform different actions when I tap and hold.
I’ve configured one of the tap-and-hold gestures to open the quick tools menu, giving me instant access to Wi-Fi, Bluetooth, auto-rotate, and other useful toggles. Another long swipe brings up the quick launcher, so I can access my most-used apps.

Home Up is all about personalizing the look and feel of the home screen, app drawer, and recent apps menu. It lets me adjust the grid size on both the home screen and the app drawer, so I can organize my apps exactly how I want.
I’ve also enabled the loop pages option, so scrolling through multiple app screens is seamless and smooth. But my favorite part of Home Up has to be the option to hide app labels. I prefer a minimalist look on my phone, and this simple tweak really cleans up the overall aesthetic.

I also use Home Up to customize the recent apps layout as I prefer the grid layout since it makes switching between apps quicker and more efficient.
3Theme Park
For anyone who loves customization as much as I do, Theme Park is a joy to use. Instead of searching the Galaxy Store for the perfect theme, I created one from scratch using Theme Park.
First you choose a wallpaper from your Gallery or the Galaxy Store. Once you’ve picked the perfect background, you can tweak the keyboard, Quick Settings panel, and icons to match it. You can even customize the volume panel colors, so it doesn’t stand out awkwardly.

Further, Theme Park lets mechange the shapes of app icons on my Samsung phone, making them all look uniform. It’s like having a personal design studio for my Galaxy device.
4Keys Cafe
Keys Cafe works similarly to Theme Park, but it focuses entirely on the keyboard. With it I can tweak every aspect of the Samsung Keyboard—from key colors and effects to typing sounds and layout.
My favorite thing about Keys Cafe is that I can create a custom keyboard from scratch. Instead of being stuck with the default layout, I can add, remove, and rearrange keys however I like. This has completely changed how I type. For example, I’ve set up a layout with my most-used emojis right above the number row, making them instantly accessible.

I’ll be honest, after switching from stock Android to One UI, I initially found the Settings app on my Galaxy phone a bit overwhelming. That’s when I discovered RegiStar, and I wish I knew about it sooner.
I’ve used RegiStar to completely reorganize the Settings menu. Now, I have my most-used settings grouped right at the top, so I don’t have to search for them.
But that’s not all. RegiStar also unlocks back tap gestures, similar to what you get on Pixel devices and iPhones. I’ve set a double-tap on the back of my phone to take a screenshot and a triple-tap to launch Gemini. There’s even an option to remap the side key’s press-and-hold function, which I’ve set to instantly mute and unmute all sounds.
Now, I’m convinced Samsung’sOneUI is better than stock Android, and I don’t think anything will change my mind.
I can’t count how many times I’ve accidentally dismissed an important notification, only to realize that I needed it later on. The NotiStar module serves as a personal archive for all your notifications, and you can choose to store them for anywhere from seven days to forever.
The best part? You can also add a shortcut to the lockscreen, so you don’t even have to open the app to see your notification history. I can also search my entire notification history to easily find that one message, alert, or update I thought I had lost, a feature you might find useful, too.
7Camera Assistant
TheCamera Assistant module helps you take better photos and videoson your Galaxy device. It brings extra functionality to the camera app, and while I don’t use every single feature it offers, a few of them have definitely helped.
Features likeAuto HDRensure the camera captures more detail in both bright and dark areas of a shot. Meanwhile,Auto Lens Switchingwill automatically select the best lens based on lighting and your chosen subject.
Another feature I’ve found quite useful isVideo recording in Photo mode. Once enabled, all I have to do is tap and hold the shutter button to start capturing a video—just like on Snapchat.
8Sound Assistant
One of the fewSound Assistant features that blew me awaywas the ability to adjust the volume of individual apps independently. This lets me fine-tune everything exactly how I like it—my music stays at my preferred high volume while games, social media, and other apps don’t blast at full volume unexpectedly.
I also use Sound Assistant to customize the volume panel. I can tweak the layout, change its position on the screen, and even add extra shortcuts for quick access to the equalizer, Bluetooth settings, and captions.
There’s even an option that lets me play sound from two apps simultaneously. This means I can listen to my favorite playlist while playing a game.
With so many useful modules, I’m honestly surprised that Good Lock doesn’t come pre-installed on Samsung phones. These modules add so much functionality and convenience that it’s hard for me to consider switching to another Android device—let alone an iPhone.
