Sony Xperia Z Ultra gets Hong Kong pricing, launches end July
Sony has revealed the devices that will are set to receive the new Android 4.3 'Jelly Bean' update. The Xperia Z, ZL, ZR, Tablet Z, SP and forthcoming Xperia Z Ultra are all in line to receive the latest flavor of Jelly Bean. Older devices may also be compatible with compatible with the update, including those still stuck on Android 4.1. Devices like the Xperia ZR and the Tablet Z will both get updates to Android 4.2 in August before getting the update to Android 4.3.
Unusually, in an effort to explain the length of time that it takes from the time Google releases the source code to the arrival of the update, it has also outlined the whole process. Sony has also explained how it has worked to streamline this process compared to its efforts in the past, as it works to get the update to compatible devices as soon as it can. Historically, Sony had been slow to get updates to devices in part because its early devices ran much more heavily customized versions of Android.
Sony's blog explains that the update process can be divided broadly into two phases -- the "Bring up phase" and the "Test, certification and approval phase." The first phase is now quicker, according to Sony, because of better collaboration between Google and Qualcomm. Sony adds that it can get through Bring up phase more quickly, because its work with the Android Open Source Project means that it run the feature upgrade program in parallel with the initial bring up work.
