Not all smartphones that are produced today are waterproof. However, just because you have a mobile device that isn’t designed for underwater shooting, it doesn’t mean that you can’t take it to the pool, sea, or ocean with you. “How is it possible?” you ask. You just need a case made of polyethylene that will take you less than two minutes to make.
Setting up Face Unlock
Android provides a plethora of ways to unlock your phone: a PIN, a password, a pattern gesture, or a typical insecure swipe. But there is one more unlocking method that most users simply ignore. In fact, the Face Unlock feature is much more secure than a simple password. To set it up, just go to Settings, scroll down to Security, tap Screen lock, and select the option you need.
