Typing a password into your smartphone is, like, so 2014. With support for fingerprint sensors in your Galaxy S7 and S7 Edge, it is easy to get spoiled by the ease of unlocking something with a touch of your finger. Your phone’s fingerprint scanner is quite literally always at your fingertips – so why not use it to improve your security and privacy?

The fingerprint recognition technology has moved on a lot from the early days too, becoming faster and more accurate in their readings. Here we will see how to effectively use Galaxy S7’s fingerprint scanner to improve the security of our device.

Fingerprint recognition

In order for fingerprint recognition to function, your fingerprint information needs to be registered and stored in your device. After registering, you can set the device to use your fingerprint for the features below:

• Screen lock
• Web sign-in
• Verify Samsung account
• Samsung Pay

• This feature may not be available depending on the region or service provider.
• Fingerprint recognition uses the unique characteristics of each fingerprint to enhance the security of your device. The likelihood of the fingerprint sensor confusing two different fingerprints is very low. However, in rare cases where separate fingerprints are very similar the sensor may recognize them as identical.
• If you use your fingerprint as a screen lock method, your fingerprint cannot be used to unlock the screen after restarting the device. You must unlock the device using a pattern, PIN, or password you set when registering the fingerprint.
• If your fingerprint is not recognized, you must take the device to a Samsung Service Center to have it reset. Then, you must re-register your fingerprints.

For better fingerprint recognition

When you scan your fingerprints on the device, be aware of the following conditions that may affect the feature’s performance:

• The Home key contains a fingerprint recognition sensor. Ensure that the Home key is not scratched or damaged by metal objects, such as coins, keys, and necklaces.
• The screen protector supplied with the device may cause the fingerprint recognition sensor to malfunction. Remove the screen protector to improve fingerprint sensitivity.
• Ensure that the fingerprint recognition area and your fingers are clean and dry.
• The device may not recognize fingerprints that are affected by wrinkles or scars.
• The device may not recognize fingerprints from small or thin fingers.
• If you bend your finger or use a fingertip, the device may not recognize your fingerprints. Make sure to cover the entire Home key with your finger.
• To improve recognition performance, register fingerprints of the hand used most often to perform tasks on the device.
• In dry environments, static electricity can build up in the device. Avoid using this feature in dry environments or before using the feature, discharge static electricity by touching a metal object.
