On the sensor side, it includes a gyroscope, accelerometer, compass, GPS, and Galileo navigation, while a fingerprint scanner handles biometric authentication. Infrared sensor, barometer, heart rate monitor, ANT+, 3D facial recognition, iris scanner, HDMI output, satellite SOS, crash detection, DLNA, stylus, and built-in projector are all absent.

The device includes a video light for use during video recording. The display is flat rather than curved, and neither sapphire glass nor an e-paper panel is featured.
