The back of Acer's Liquid Z4's surfaces repel fingerprints and grease.

Under the Liquid Z4's subcompact hood is a dual-core 1.3GHz processor linked to 4GB of internal storage.

To enhance music and movies, the Z4 relies on DTS Sound technology.

CNET's Reviews team was disappointed too by the screen's washed out colors and lack of lumens.

Also, the Liquid Z4's display's image quality drops dramatically when tilted off-angle, especially vertically.
