Lock Star causes the display brightness to spike high on the AOD. And After unlocking the phone, the brightness stays high for a moment and then drops with a slight delay. Please fix this brightness issue on the Fold 7!

"If you own a Samsung phone and aren't using this app, you are missing out on 80% of what your hardware can actually do. Good Lock isn't just a basic theme changer; it is an official, modular playground that lets you rewrite how the entire user interface behaves.

I'd love it if sound assistant was available for tablets. I have a Samsung Tab 11a. I want to run 2 live streams with sound at the same time.

Interesting and nice apps. It lets you customize your own based on your preference. So much to explore into interesting things
★★★★☆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.

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.

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!
