Sony Xperia Z Android update takes away Wi-Fi when Smartwatch 2 is connected

Sony has been left red-face after an update for its Xperia Z smartphone caused it to switch off Wi-Fi or withdraw support for the Smartwatch 2.

The firm’s Xperia Care website has been inundated with customer complaints that after upgrading the Xperia Z to Android 4.3 it loses its connection to Wi-Fi that only comes back once the Smartwatch 2 has been switched off.

“After upgrading to android 4.3, I lost my connection to Wi-Fi. Only solution I found is to turn off my smartwatch 2, after that my Wi-Fi connection came back. Please solve this issue, I don't want to throw away my Smw2,” stated one forum user.

Sony has so far been silent over the reports and is likely to release an update for the bug as and when it has developed a fix. It is also worth considering that the Xperia Z is one of the Sony devices that will be getting Android 4.4 although when it will receive it is a well-guarded secret.

The company unveiled the Xperia Z smartphone at CES 2013 in Las Vegas this time last year with the phone eventually released in the UK in March 2013. The device has a 5in screen with a full HD 1,920 x 1,080 resolution and is packed with a Qualcomm quad-core processor clocked at 1.5GHz and supplemented by 2GB of RAM as well as 16GB of onboard memory that can be expanded using a microSD card.

It has an impressive 13-megapixel camera on the back as well as a 2-megapixel snapper on the front with the added bonus that the device is both dust- and water-resistant.

Since the release of the Xperia Z the company has also released the Xperia Z Ultra that has a larger 6.4in screen and a faster processor to boot.
