Sony is in the process of rolling out a couple of new over-the-air updates for the Xperia Z1 and the Xperia Z Ultra. Neither will bring Android 4.3, but there are some significant maintenance updates that we would advise to download and install.
The Xperia Z1 was released last month, and features a 5-inch TFT capacitive touchscreen with a resolution of 1080 x 1920, a 2.2GHz quad-core Qualcomm Snapdragon 800 processor, an Adreno 330 GPU, 2GB of RAM, 16GB of internal storage, a 20.7-megapixel rear-facing camera and a non-removable Li-Ion 3,000 mAh battery.
Whereas, the Xperia Z Ultra was launched back in July, and packs a gigantic 6.4-inch capacitive touchscreen with a resolution of 1080 x 1920, a 2.2GHz quad-core Qualcomm Snapdragon 800 processor, an Adreno 330 GPU, 2GB of RAM, 16Gb of internal storage, a 8-megapixel rear-facing camera and a non-removable Li-Ion 3,050 mAh battery.
The upgrade brings several camera tweaks for the Xperia Z1, including new camera algorithms for “better all round performance.”
The Xperia Z Ultra update brings “optimized touchscreen sensitivity ” for fingers and styluses, therefore, effectively broadening the range of input methods, empowering the device to compete with the likes of Samsung’s flagship Galaxy Note III.
In addition, both the Z1 and Z Ultra will receive battery life enhancements, display calibration tweaks and significantly faster e-mail synchronisation over Microsoft Exchange.
