Acer unveiled the first smartphone featuring 4K Ultra HD recording capability, which is driven by Qualcomm's new Snapdragon 800 processor. Users will need a 4K TV to benefit from the higher resolution as the Acer Liquid S2 offers a 6-inch IPS display with 1080 resolution.
LTE is supported at up to 150 Mbps. It also features the new 802.11ac Wi-Fi.
A Zero Air Gap Display removes the air between the touch panel and LCD module, thereby providing improved tactile sense and reduced reflection boosting readability even in sunlight.
