Samsung please add an option to lock individual apps.

Doing this through secure folder is gimmicky and time consuming. FIX IT

Hi @AntonCyt! 

You can submit suggestions in two ways, both will require Samsung Members App. I'm not sure how it will look in English, but basically what you need to do is:

1. Tap the "Help" button

2. Search for something like "Sending a request" with a "Question" option

3. In "Question" tab choose category that is the closest to your request's subject.

4. Describe your suggestion and tap the "Send" button.

The second way of doing this is by going through Help, then finding the Chat option and texting with someone from technical support :]
