ZTE Grand S3 First Impressions: Ordinary Android With One Neat Trick

ZTE has a fairly large booth at the ongoing Mobile World Congress trade show this year. The Chinese manufacturer is one of the players launching affordable Android devices and offering serious competition to established brands in markets all around the world.

One of the models grabbing attention here is the ZTE Grand S3, mainly because of a unique biometric security feature. While other devices have employed various facial recognition techniques, the ZTE Grand S3 can scan the pattern of blood vessels in a user's eyes. All you have to do is glance at the front camera to unlock the phone, andZTE says this is safer and more reliable than reading fingerprints.

The feature seemed to work exactly as described. A booth attendant demonstrated it by first dipping into the phone's settings to set up recognition from scratch, and then repeatedly unlocking the phone from various angles. The setup process took about 30 seconds, but was as easy as staring into the front camera. The actual recognition was near-instantaneous. You do it exactly as you would set up a PIN code or dot pattern.
