Sony today promised to update several of its devices to Android 4.3, though it didn’t say when the update might become available.
Sony said it is already making good progress with updating the Xperia Z and ZL from Android 4.1 to Android 4.2. Down the road, it will update both the Z and ZL, as well as the Xperia ZR, SP, Z Ultra, and Tablet Z to Android 4.3. Sony also said that it might update a few phones from Android 4.1 directly to Android 4.3, but it didn’t name those devices.
The timing for the updates will vary by region, carrier, and device.
