Sony has announced that it's started pushing out maintenance updates for two of its newest high-end phones, the 5-inch Xperia Z1 and the 6.4-inch Xperia Z Ultra — and there are some noteworthy fixes for both devices.
First up, the Xperia Z1 gets camera tweaks — new camera algorithms for "better all round performance." There have also been changes to Sony's smart camera platform, the manufacturer says, allowing built-in mini-apps like sweep panorama and the various AR capabilities to run more smoothly.
Meanwhile, the Xperia Z Ultra gets "optimized touchscreen sensitivity" for fingers, pens and styluses. And both the Z1 and the Ultra will receive battery life enhancements, display recalibration tweaks and faster email sync over MS Exchange. Both new sets of firmware are still based on Android 4.2 Jelly Bean, so we're not dealing with a major update here. Nevertheless, it looks like there's some good stuff for Xperia Z1 and Ultra owners to get stuck into.
