Install S secure App from Galaxy store. This app is useful for you to lock and mask your device App's
App lock is inbuilt in Samsung but didn't provided any launcher or settings for it. Ssecure is just a launcher for app lock. Even without ssecure you can use it by using any activity manager. You can uninstall manager but still use app lock. But if you uninstall ssecure app lock will be resetted.
And Be Carefull Bro anyone can uninstall the S Secure just like normal app so you Data will be simply exposed.... 🤦♂️🤦♂️🤦♂️... So for that only I downloaded another app from playstore which not uninstalble without our password... Why Samsung Why😓😓😓😓
