Although the latest version of the operating system, Android 6.0 Marshmallow was released last year, the truth is that there are still many, including high-level mobiles, that do not have firmware updated to this latest version, including the Sony Xperia. However, new information coming from the UK seems to confirm that the Sony Xperia will start updating to Android 6.0 Marshmallow on March 7th.
Specifically, the information comes from Sony Mobile in the UK, who claim that the Sony Xperia Z5 and Sony Xperia Z4 Tablet will begin to receive the update to Android 6.0 Marshmallow on March 7. Considering that they speak of a very precise date, it seems quite likely that it is a real date. However, some factors still need to be taken into account regarding this date. One of them is that it is simply a date for a specific region. If it is a release of the update in the United Kingdom, it is possible that the launch in Spain will not occur on that date but later.
In addition, we are talking about a high-level mobile and tablet, and recently launched. That means that older generation phones, such as the Sony Xperia Z3, or the Sony Xperia Z2, as well as lower-end phones, such as the Sony Xperia M5, for example, will also receive the update later.
Finally, it should be borne in mind that if we have acquired any of these smartphones through an operator, and the firmware has customization by the operator, the update will also take longer to arrive, so in the end, although we start March 7, we can only use this date as a reference. This is good news for users of the Sony Xperia Z5 and Sony Xperia Z4 Tablet, although we will see how long it takes for the rest of the updates to arrive for the rest of the Sony Xperia smartphones. Recall that in the releases of other updates, Sony has released the update for the entire range of smartphones at the same time, so it is possible that both the high-end of previous years and the mid-range of this year will also begin to receive an update on 7 of March. In this case, it remains to be confirmed when the update will arrive on smartphones in Spain.
