Huawei Pura 70 Ultra Retractable Camera: Explained

The Huawei Pura 70 Ultra introduces a groundbreaking feature: a retractable main camera. While not the first phone to boast this innovation, the Tecno Phantom X2 Pro was its predecessor. This design tackles the challenge of blending large sensor capabilities with a slim phone profile.

Understanding Retractable Cameras

A retractable camera conceals its lens within the device when not in use, eliminating the typical camera bump found on smartphones. The lens extends when required for capturing photos or videos.

The Mechanism Behind Pura 70 Ultra's Camera

The main camera of the Pura 70 Ultra resides in a concealed compartment within the phone. Upon activating the camera app, a precisely engineered mechanism comes into play.

Technology Components

  • Stepper Motors: Two stepper motors power the camera's movement, extending or retracting the module smoothly through controlled electrical pulses.
  • Telescopic Lens Cover: A telescopic cover shields the lens when not in use, protecting it from dust and scratches.
  • Sensor Stabilization: Sensor-shift stabilization ensures image sharpness by compensating for hand movements, reducing blur.

Advantages of Retractable Cameras

The retractable design offers various advantages, including:

  • Larger Sensor: Huawei employs a 1-inch sensor in a compact space, enhancing light capture for sharper images, especially in low-light settings.
  • Compact Design: By integrating the retractable module, Huawei eliminates the hefty camera bump, enhancing ergonomics and comfort.

Additional Features and Concerns

  • Speed and Durability: The retraction mechanism operates swiftly, promising over 100,000 cycles of extension and retraction.
  • Water Resistance: Despite moving parts, the Pura 70 Ultra maintains an IP68 water and dust resistance rating.
  • Drawbacks: Potential points of failure exist with the moving parts, impacting long-term durability and possibly contributing to the phone's premium price.


The Huawei Pura 70 Ultra's retractable camera represents a significant advancement in mobile photography, emphasizing a larger sensor and sleek design. While longevity and reliability remain to be seen, this innovation paves the way for enhanced image quality and user experience in smartphone photography.
