Comments on Good Lock for Android

★★★★☆ Maxx W · Nov 5, 2026
Love this app for customizing my phone, however after the recent UI update on my Samsung 24Ultra, certain features aren't working anymore.
★★★★★ Michael E · Oct 8, 2026
Can you please make option to make volume and brightness buttons narrower? With the new update UI9 on Samsung it is huge
★★★★★ Joseph Janukatys · Oct 11, 2026
I've been using this app for about a year and it's great. It does exactly what it says, lets you customize your android.
★☆☆☆☆ Amy Chen (Mii-chan) · Nov 3, 2026
I shouldn't have installed this to show AM/PM on my phone. It doesn't even work on the lock screen.
★☆☆☆☆ Kaushik Sarkar · Nov 5, 2026
Only 4 plugins available!! what's this?!
★☆☆☆☆ SUMAI · Oct 10, 2026
WITH THIS APP & OTHER APPS INSIDE OF IT, I STILL CANNOT GET THE ORIGINAL CLOCK FACE I HAD BEFORE THE 9.0 UPDATE. How is this right to NOT let people control more of how they want THEIR PHONE to display?? UNINSTALLED!!!
★★☆☆☆ TiffanyDashell M · Oct 7, 2026
Doesn't work after recent software upgrade. I was using several of the apps in Good Lock until the recent software upgrade for my Samsung 26+ Ultra. I'm on an unlocked version of the device.
