A few images of Lollipop running on an Xperia phone have hit the web, and the most noticeable takeaway is what Sony has done to the navigation buttons.
The full-size screenshots can be found over in the original XperiaBlog post. All we care about is what's visible at the bottom of each. To put things simply, Sony has changed the icons, and not necessarily for the better.
Here are the on-screen navigation buttons on a Nexus device.
Sony promised it would bring Android 5.0 to all its Z series phones, and now it's starting to live up to that. The newest generation Xperia Z3 and Z3 Compact are first up. The OTA is rolling out now to devices in Nordic and Baltic countries, but other markets should follow within two weeks. There's a nifty demo video to go along with the announcement.
The one Nexus-style smartphone that's even bigger than the N6 is getting its Android 5.0 update today. At least a few owners of Sony's Z Ultra (nee Xperia) Google Play Edition are getting over-the-air updates to Lollipop, as evidenced by this XDA thread. Conveniently, one of those fine folks has found the link to OTA ZIP file, so you can download and flash it manually to your own phone if you don't want to wait for the rollout.
Sony's mobile division may be spiraling into oblivion, but that isn't stopping the company from dropping new hardware at Mobile World Congress. First up is the really hot Xperia Z4 Tablet, a very light and thin 10.1" tablet.
Some of Sony's older hardware (well, relatively speaking, anyway) is getting updated to Lollipop today. If you own an Xperia Z (LTE model), Xperia ZR (LTE model), Xperia ZL, or Xperia Tablet Z, all released in 2013, check your status bar for an over-the-air update. According to Xperia Blog and the always-reliable XDA, all four of these devices are being upgraded as of now. As usual, it may take a few days or even a week or two for the rollout to reach you.
Sony is ready to take its Android phones to the next Lollipop level. The company is sticking to its previous word that the Z series devices will start getting Android 5.1 in July and is starting the roll-out today with the Z3 and Z2 series. So consider yourself lucky if you have an Xperia Z3, Z3 Compact, Z3 Tablet Compact, Z2, or Z2 Tablet, because you're among the first Sony owners to get Android 5.1... well, if we don't count the GPE Z Ultra.
You'll obviously get all the benefits of Android 5.1, like better volume control and plenty of design and usability tweaks, but Sony has also added a few improvements to its own software.
Sony began pushing out an update to the Xperia Z3 on December 11th, but we didn't know exactly what it contained. Well, we do now. Sony has graciously added a changelog to the page. The Z3 and Z3 compact are getting the same features, but it's a nice little update.
