S23 Ultra. Edge+ Style by Key Word. Finally figured out how to get the notifications to work properly for Google Messages and Fb Messenger. It would be nice is when you use customer style, it would default to the app icon unless you have it styled by key word or only use the style by key word settings. It would also be great to have the option to style for a specific contact instead of key word.

It's Good Lock. Samsung's users, do I need to say anything more? Everyone else, this is ultimate customization at the tips of your fingertips. Never had better! Also, no ads 🙌🥹😎🫪

★★★★☆ Chandler Schuldiner · Jul 14, 2026

Most tools are really good. A few, like Quick Star and Wonderland, are completely unusable because they repeatedly crash before you can do anything with them. My favorite modules are Routines+, Sound Assistant, Register, and One Hand Operation +. I genuinely couldn't live without them - and they never crash. If they ever fix the crashing issue, I'll update to 5 stars.

Found on Samsung forums about how you can use it to trigger game booster on apps that I custom define, and it's a game changer. Samsung releasing this app for you to customize how you want your phone to be as amazing. Definitely my top three reasons I would keep buying a Samsung phone

Samsung sucks. I wanted to change the color of my navigation bar. Samsung dumbed-down its One UI in version 8.5, effed up their dark mode, and I had to install Good Luck to customize the navigation bar the way I wanted. But Good Lock wouldn't work without NASTAR. So, Samsung now requires two separate apps to customize my navigation bar the way I want. I'm done. Google Pixel 10, here I come. Samsung just lost a near 20-year customer who spent $15K on their phones over two decades. Eff Samsung!

Whenever I download good lock, it never comes up with theme park for me. I see theme park for a split second, and then its gone! If I'm able to access theme park, I would be more than happy to use good lock.

★☆☆☆☆ Jon Woodbury · Jul 6, 2026

Doesn't really work. . Samsung removed standard features from their OS then created this app to put them back...only it doesn't actually work most of the time. Simple things that should be built-in, like looping the home screens and actually showing the Bluetooth connection status icon have toggles in this app but don't actually change anything. Pretty useless.

For the past few months, I have observed an issue where widgets on the inner screen are overlapping. This can be resolved by disabling and re-enabling the "Home Up" module within the Good Lock application.
