excellent Samsung app for customizing for customizing your device. it's lightweight and easy to navigate. low-impact on battery. I used it to install navstar which are just the height of my navigation bar. it was needed because the navigation bar was hiding a lot of other apps settings at the bottom of screen. highly recommended

S23 Ultra. Style by keyword feature is unreliable. Even with the generic style that should show up for every notification, it only works sometimes. Works for only certain contacts in Google Messages, never for Facebook Messanger. Support is not helpful. Love the concept but inconsistent. I thought maybe it was RCS vs SMS message but doesn't seem to be the issue. A fix would be greatly appreciated.

alright. I've downloaded the much talked about "Good lock" and I'm underwhelmed as some options I see on YouTube videos are not available. also the few that I tried to enable, when I try to open them, it doesn't take me to the menus that I thought I would see. is this some region-dependent App in terms of functionality. cos right now, I have no use for something that doesn't work as advertised.
