The Xperia Z1 was initially shipped with Android 4.2 (Jelly Bean) with Sony's custom launcher on top. Some notable additions to the software include Sony's Media applications – Walkman, Album and Videos. NFC is also a core feature of the device, allowing 'one touch' to mirror what is on the smartphone to compatible TVs or play music on a NFC wireless speaker. Additionally, the device includes a battery stamina mode which increases the phone's standby time up to 4 times. Several Google applications (such as Google Chrome, Google Play, Google search (with voice), Google Maps and Google Talk) already come preloaded. Sony also radically changed its camera user-interface; it added new features, such as TimeShift and Augmented reality (AR) effects such as a walking dinosaur.
