7 Useful Features of Your Smartphone That You Don’t Use

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.

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.
