Sony Xperia Z2 and Z3 are getting an update in their firmware to fix some tiny issues and requests. They will keep 5.0 Lollipop, which expresses that these are mostly optimizations rather than general alterations. The most significant feature is possibly the fact that the application switcher has a close all key, and some other goodies as well.
Making the LED light autonomous of the sounds is another feature alteration. Before, setting the device on silence mode also turn off the LED indicator. Which it was possibly annoying, because the light is what you want in place of audio. This update will permit that have security policies imposed by services as Microsoft Exchange to see notification content on the lock screen, which was not allowed for security in the previous version.
Also, the locik screen gets a bug fix, erasing a problem where it would mistakenly state the phone had no service at the instant. Sony has made a backend alterations to repair some troubles that users had in moving documents between the internal and external SD cards. The mode ultra stamina was producing some problems for messaging in the prior version but that was fixed too.
The company advises that your location and carrier may affect when you see the update, but the rollout starts today.
