The Xperia Z1 has only been available to purchase for just over a week now, and Sony is already pushing out an over-the-air (OTA) update to the HSPA+ version of the Japanese company’s flagship smartphone for customers based in India.

The Z1 is a very respectable smartphone, packing a 5-inch TFT capacitive touchscreen with a resolution of 1080 x 1920 (441 ppi pixel density), a 2.2GHz quad-core Qualcomm Snapdragon 800 processor, an Adreno 330 GPU, 2GB of RAM, 16GB of internal storage (expandable up to 64GB via microSD), a 20.7-megapixel rear-facing camera and a 3,000 mAh battery.

The handset ships running Android 4.2 Jelly Bean, skinned with the latest version of Sony’s Xperia UI, and will be upgradable to 4.3 in the not-to-distant future.

This update brings a multitude of bug fixes, speed optimizations and minor tweaks to the kernel source code, which all contributes to improving the stability of the device.

Like most OTA upgrades, version 1.4.1.G.1.531 is being pushed out in stages. So if you haven’t received a notification for the update, you can head into “Settings,” then “About Device,” and select “Check for Updates” to manually scan for the new firmware version.
