★★★★☆ Alexander Balenoüs · Apr 21, 2026

Great app, used on all my Samsung's. However, on my S25, when I enable the task changer in Home Up, the screen flickers very often. When I disable Home Up, it stops. I hope you can fix this.

★★★★★ J. · May 16, 2026

Thank you for including the Fold back in having AOD control, that autobrightness is wild and albeit it took a while to add back Lock Star team... thank you. IDK why your colleagues make the AOD autobrightness so terrible even if you had autobrightness on, but IDK why they can't just make the autobrightness off should include the AOD, but hey, you all continue to fix things so kudos

★★★★★ Varie · Apr 25, 2026

Ixm not sure if this feature is already added on OneUi 8.5, but please let us rename the apps. Also let notif icon for each app reflect what has been changed in icon customization in Theme Park. I used another icon for a specific app so that nobody would know what it is but when it sends notif the original icon shows in notif bar. Please make it happen.

★★★★★ Ken · May 31, 2026

Thank you for bringing the option for manual AOD brightness for the Galaxy S25 Ultra, now I can see the clock properly at night.

★★★★★ Sean · May 4, 2026

Cool app, ALTHOUGH!, DEVS! When using the lock screen "lock star thing, I put the calendar as one widget then 'world clock below that. Even when I said the location to local city (because I just want a regular clock under my calendar) it only ever displays bloody London. I realize it's world clock and not just clock, would be good if I could just do regular clock edit, I see there's clock right-hand top corner of calendar, but still. World clock only ever shows London, regardless of city's added

★★☆☆☆ Rachel · Jun 5, 2026

Used to be great, loved this app but the new 8.5 update and good lock aren't compatible, so this is pretty pointless until fixed

★☆☆☆☆ Vasu gunnam · Jun 4, 2026

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!

★☆☆☆☆ Daniel Adeyinka · Apr 26, 2026

But why are most of the Good lock features not available for many regions across the world? In Nigeria, the only Good lock feature we have is Home Up. Quite unfair for s26 ultra users in Nigeria 🤦🏽‍♂️🤦🏽‍♂️🤦🏽‍♂️ Edit: Download Good lock and all other adons from Samsung stor instead. This is how to get the full experience
