Thanks for letting us know your difficulty while using your Samsung Galaxy phone. I feel you, whenever there's something goes wrong on your device, you are worried. If it happens to my device, I will feel bothered too.
But before that, be sure to check if your device's software and related apps (Nice Lock) are updated to the latest version. To update your mobile device's software, follow these steps:
Step 1.Go toSettings>Software update.
Step 2.Tap onDownload and install.
Step 3.Follow the on-screen instructions.
Did you try closing the app and check if there is any update? or try clearing its cache and data will revert back to its normal working condition.
By the way, the Good Lock app is now available for you to download, you may want to try it.
If that doesn't fix the problem, you may submit an error report through the Samsung Members app as follows:
