App Lock Master Customer Insights

1. Norton app lock offers those features and more...It is supposed to keep unwanted eyes from seeing certain things; when it takes awhile to kick in (when u open each app) there's enough time to see (i.e.) your message list and everyone who has sent/received them and a preview of the message..or your email inbox....this COMPLETELY defeats the ENTIRE PURPOSE of installing this app.

2. Except for its daily maintenance activity to ensure sustained good functionality which is sometimes boring, I still think it deserves a 5-Star rating for excellence.Look, this is a really good app!! I'm impressed! BUT... there is one small issue I have with it... I think it needs a switch to be able to deactivate the app if desired.

3. Whenever my phone is rebooted, nothing is required to get it... no pin, pattern, password or fingerprint and all the apps are accessible.

4. Why can't you do the same? I would also like to be able to add apps, which l have cloned, to my home screen, like you can do with Parallel Space.Not so great.

5. I checked everything including rebooting the phone to see will I be able to bypass and get into apps I have locked.

6. Problem is I was able to uninstall app without being required to enter password, so developer please look into that issue.

7. Only couple things that need to be fixed/added to it.***Clone won't work the cloned apps sit in a loading screen with the app icon and never stops loading.

8. Not sure if it's because the phone is old or what but not able to find a lock app with those options.

9. I would like to be able to stop someone from turning off mobile data, turning off the phone or even putting the phone in airplane mode.

10. They promote the app's other features (e.g. freeing up space, optimizing battery life), some of which my phone could do on its own.

11. Also, the fact that you can't use biometrics to unlock while screen sharing; the lock pattern can be seen by everyone and anyone looking at the TV.
