## Sixth generation (2019)

In May 2019, Asus unveiled the ZenFone 6 (Asus 6Z) at a press event in Spain. The ZenFone 6 features a rotating camera in an attempt to reduce bezels and provide an all-screen front. There is a dual camera setup on the phone, which normally resides on the back, but rotates when needed to become a selfie shooter. Asus allows for the rotation of the Liquidmetal camera module to be controlled using a stepper motor. This allows users to stop the rotation midway to take photos at interesting angles and can take automatic panoramas. The company has also added fall-protection for the camera module, which will automatically retract the camera to its base position if the phone detects sudden movement.
The Asus ZenFone 6 prices starts at EUR 499 for the 6 GB + 64 GB variant, going up to 6 GB + 128 GB version will retail at EUR 559, and finally, the top-end 8 GB + 256 GB variant is priced at EUR 599. It was immediately available via the Asus eShop on that day and would start shipping from May 25. Asus has revealed that the phone will be offered in two colours – Midnight Black and Twilight Silver.
The ZenFone 6 was announced to be released in India on 19 June 2019 under the name Asus 6Z, due to a trademark ruling by the Delhi High Court against the sale of products branded "Zen" or "ZenFone" in conflict with Telecare Network India's Zen Mobile.
