The Huawei Y7 sports two essential security features. Face Unlock and Fingerprint sensor. The Face Unlock has a facial recognition feature. All you need to do is set your face as the password to your phone. This feature will then grasp the parameters of your face and save in its database. So the next time you want to unlock your phone, you just need to take a glance at it, and the phone will automatically unlock. This convenient feature eliminates the need for textual passwords, and your worry to remember them. The fingerprint sensor is another security feature that helps you keep your phone secure.
