Comments on Good Lock for Android

★★★★☆ 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.

Found on Samsung forums about how you can use it to trigger game booster on apps that I custom define, and it's a game changer. Samsung releasing this app for you to customize how you want your phone to be as amazing. Definitely my top three reasons I would keep buying a Samsung phone

★★★★★ Vicki Brown · Sep 15, 2026

YES!!! I used to use ADW Launcher, but it doesn't run on my new phone. One UI isn't bad, but some things about it annoyed me - the app button stuck to the right end of the shortcuts "tray", the 3x3 teen bitty icons in folder previews. Now I can fix those issues, using the Home Up module in Good Lock. YEAY!!

★☆☆☆☆ maher shtat · Aug 7, 2026

For the past few months, I have observed an issue where widgets on the inner screen are overlapping. This can be resolved by disabling and re-enabling the "Home Up" module within the Good Lock application.

I liked it before I got a new phone for 20k at good lock isn't on it and some features isn't on the phone it's a galaxy a27 so like samsung just why

★☆☆☆☆ Malin Hansen · Sep 13, 2026

On the theme page you can't make an icon pack, you can make it separate to the theme but can't apply both at the same time, you used to be able to put together a whole theme but can't anymore

★☆☆☆☆ Robyn C · Sep 5, 2026

Always On Display Settings Don't Stay. I set brightness to 33% but almost immediately, the brightness is at 100 on the Always On Display. Very annoying as I don't want it full brightness draining the battery.

★☆☆☆☆ Huh · Aug 28, 2026

I genuinely don't know if it's my device but whenever I install a new extension and try on a new look (like my keyboard or apps) and i don't want it any more I try EVERYTHING to take the extension off (deleting the extension, clearing cache and data of the WHOLE app, force stopping the app) and my phone is STILL STUCK ON THAT NEW STYLE. I tried to change it on my keyboard to put it back to default but for some reason it says rhat it's the default?? And noe my phone is stuck like this.
