Comments on Good Lock for Android

★★★★★ Larousson BAZIL · Oct 11, 2026

Amazing app! It gives me complete control over customizing my phone exactly the way I want it. Highly recommended for anyone who loves personalizing their device. #Samsung4ever🥳

★★★★☆ cornel van der westhuizen · Sep 3, 2026

I am disappointed with the fantastic app for removing the sticker option for the S Pen pointer. I liked that I could create stickers for my S pen pointer, that's exactly why I downloaded Good Lock in the first place, is to customize my S pen, I am not using an entire picture for a pointer it looks weird, sorry but please fix this problem.

★★★★☆ Çingiz · Oct 12, 2026

Giving users the ability to customize is amazing, I just think Samsung could add more to the certain modules. For example: home up module needs more options, like disabling app drawer gestures for people who want to use old-school button. Adding different animations for left-right swipes both in home and app drawer.

★★★★★ Lundyn Sepulveda · Sep 11, 2026

I wish I could post pictures of how cool this can make your home screen. The flexibility allows for a lot of creative freedom!

★☆☆☆☆ 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!!!

★☆☆☆☆ Denise Neely · Oct 7, 2026

My operating system was updated today and now good luck is not working. It says something to the effect that this version does not work with this operating system what the heck what am I supposed to do now

★☆☆☆☆ Dj A · Oct 1, 2026
