LOVE this app!! I've customized pretty much everything on my phone 😂 it's so easy and you can find step by step tutorials on Tiktok, YouTube, Google etc . there are a few things I can't do because my phone is older but it's no biggie. it also integrates some things with the phone settings so you don't always have to go to the app every time

I've seen many videos showing the good lock of having many different kinds of customisations. I've recently updated to UI 8.5 which could allow my options to expand, but I still have only 3 options, I'm not really sure what the issue is at the moment, but as far as I see the software and Samsung phone model really depends.

please do something about this UI update. It disabled my launcher widget and now multistar is no use. It was perfect with good lock and now I can't use it even though I uninstalled and installed it back. I don't need game widget, but I need launcher widget! And you guys are doung great work cause I desperately need it to use my phone more functionally and efficiently.
