Official Change log of 23.1.A.1.28 firmware update for Xperia “Z2″ & Xperia “Z3″ series

Besides software improvement and enhancement, following features are included in the 23.1.A.1.28 firmware update:

• Ensured the lock screen/notification bar doesn’t indicate “no service” when the device has coverage
• Added a Sony feature; bringing back the “close-all-button” in the activity menu, so you can easily close all apps at once
• Unblocked devices with server policies (such as Exchange Active Sync for e-mail), to enable the new Lollipop lock-screen notifications
• Ensured the LED light is lit across all sound modes – and no longer offset by “silent”
• Made the necessary fixes to enable the easy movement of content from internal memory to external microSD card (something we saw affecting a few devices)
• Improved messaging functionality in Ultra stamina mode – some conversations could not be opened before in Ultra stamina mode

Sony Xperia Z3. What to do after major upgrade?

Wiping the Phone's Cache Partition:

NOTE: Assuming that your smartphone is not working as intended and you're thinking about master resetting it, then you might want to try and wipe the phone's cache partition first. Wiping the phone's cache can solve numerous issues without having to factory reset and lose all your personal data. To wipe the cache partition:

1. With the smartphone turned ON, press and hold the "Power" and "Volume Up" buttons
2. Wait for the display to turn off and for the smartphone to vibrate three times
3. When the smartphone's screen shuts off, release all the buttons
4. The cache partition should now be wiped. Press the "Power" button to reboot your Xperia Z3 as you normally would

NOTE: If wiping the cache partition hasn't solved your issues then you might want to consider factory resetting it.
