It seems that Sony is working hard to improve the speed with which it updates its terminals, especially the most recent ones. An example of this is that there is information that indicates that the Android 4.4 version could arrive this November at X.
In addition, it seems that there is even speculation with the possible day on which it would be deployed: the 7th of that month. If this occurs, there would be two very important details: the first is that 4.4 Android KitKat It would be announced before that date (and we must not forget that it is expected with the new Nexus 5) and, the second, that surely the Sony Xperia Z1 would be one of the first models to receive this version of the system. Google operative (yesterday already we indicate some information about Samsung terminals).
Regarding what this new version of Android can include, very little is known for sure ... apart from the name it has. Obviously, certain improvements and some additional functionalities are included (those specific to the camera are the most commented on), but the truth is that if it is confirmed that the Xperia Z1 gets the update so quickly, we are talking about an excellent hit of effect Sony regarding their work in providing this after-sales service.
As is usual with Sony firmwares, and in this case it is not expected to work in a different way, a "layer" customized by the manufacturer will be included above the operating system with its own applications, such as multimedia players or access to PlayStation Mobile. The good thing is that the one developed by the Japanese company is one of the less intrusive that exist and, furthermore, it does not require large resources to make it work.
Ultimately, if the information is true, it won't take long to get to know Android 4.4 KitKat and, by extension, the Nexus 5. In addition, users with an Xperia Z1 can quickly implement this version of the operating system on their terminals. I mean, good news no matter where you look.
