The Liquid Z5 runs a dated version of Android – 4.2 Jelly Bean – the latest being Android 4.4. Acer has customised Android with its own skin, which brings a few of its own features. These include floating widgets, such as a calculator which you can use while reading your emails. Overall, the phone's processor performs basic functions well, but the device is not striking as it is a dual-core MTK chip, similar to those used in previous Acer Android phones. It struggles against the top-end phones.
