The Sony Xperia Z Ultra is equipped with that aforementioned 6.4 inch screen with resolution of 1080 x 1920. That works out to a pixel density of 342ppi. A quad-core 2.2GHz Qualcomm Snapdragon 800 CPU is driving the phone, which also includes 2GB of RAM and 16GB of native storage (11GB of which can be accessed by the user). A 64GB microSD slot is also available if you need more storage. The back and front facing cameras weigh in at 8MP and 2MP respectively and a 3050mAh battery keeps the lights on. With IP58 certification, the phone can withstand a dunking in up to 3 feet of water for no longer than 30 minutes.
The update, which weighs in at a hefty 448MB, also eliminates that nasty bug that prevented users from uninstalling apps. Other bugs exterminated include one dealing with security settings, a clear data bug, and one that affected the performance of Google Now.
