Which devices?
Sony indicates that the Sony Xperia Tablet S and Sony Xperia ZR in August will receive. an update to Android 4.2 Subsequently, an Android 4.3 update will be released, just like the Xperia S, Xperia ZL, SP Xperia and Xperia S Ultra.
for the appliancesaddition, Sony also says to investigate to update. several devices directly from Android 4.1 to Android 4.3 the possibilities Presumably it to devices like the Xperia T and V and possibly the Xperia S. In a blog post Sony indicates that the update process to Android 4.1 is not running smoothly and that it is all very long.
Faster updates
a single post on Sony Developer World let Sony know how to make an update in works. The update to Android 4.3 Sony can at least work a lot faster. The picture shows how making updates previously in his work was compared to how it is below.
Previously there were three phases that were one by one. Was first, once the source code for the new Androdversie became available, ensured that the new version of Android running on a device. Then the Sony own applications improved and tested in this new Android version and then follow the testing, certification and approval phase. Incidentally, according to Sony takes that last part, especially be approved by different countries and providers, the most time.
with Android 4.3 two changes. First, Google called Platform Development Kit (PDK) released. This package contains information about an upcoming version of Android and is given to a number of partners about two months before the release of a new Android version. This Sony can already start before the new version comes with the preparation of the system.
The second change in Android 4.3 is that Sony is working on an open source version of the system software of the Xperia S and Xperia Tablet Z. This software system is based entirely on standard Android and ensures that it is easy to create a new Android version for a handset: Sony changes in the system need to make a new version ie not first fit. This ensures that Sony can develop parallel: once the open source version of the new Android version is ready, you can start with the preparation of its own software like the Walkman app and home screen. When Sony make changes to the system eventually ready, is developing its own apps already come a long way.
So it seems that the update to Android will get the update to Android 4.2, 4.3 faster but we do not expect the update within a few weeks is perfect: it takes the test project for far too long. Generally, Sony updates for a particular device in ‘one time’, whereby all devices receive the update within a few weeks. This means that the update (almost) has been approved to be released. Anywhere When competitor Samsung takes this process generally longer: Samsung seems to bring the updates once approval for a particular provider or within a particular country.
