Xperia Z1

Performance tweaks and camera improvements for Z Ultra among changes in latest Sony firmware

Sony had previously promised that the Android 4.3 rollout for certain Xperia phones would begin this month, and now the first two devices on the list are being updated. Android 4.3 for the Sony Xperia Z1 and Xperia Z Ultra has started rolling out today, bringing an update from 4.2.2 and some Sony software improvements.

Among the changes are enhanced performance and updates to Sony's suite of built-in apps, such as Messaging, My Xperia, Smart Connect, Small apps, Track ID, Sony Select and the media apps, including Walkman, Album and Movies. As of this release the Xperia Z Ultra also gets access to Sony's "Smart Social Camera" feature from the Z1, which lets the rear camera use Sony's downloadable camera apps. The new firmware also supports downloadable themes through the Xperia Themes system, a feature Sony says it'll expand upon in the future.

Update: Xperiablog also reports that the Z1 camera issues for bootloader-unlocked phones has also been fixed.

The update should be available now for some Z1 and Z Ultra devices, though Sony points out that as with all updates it'll take time to roll out to all regions and carriers. (We're not yet seeing anything on our unlocked UK Z1, for what it's worth.) If you're updating your Xperia Z1 or Z Ultra today, hit the comments and let us know how you're getting on.

Sony Xperia Z1 and Z Ultra Android 4.3 updates rolling out


This is great for those that have the phone. I got my 4.3 update on my tmobile xperia z couple weeks ago. I would have probably kept it if it was the 4.4 update but I am going back to my Note 2 that is rooted and has a kitkat rom on it. I wish the z1 was in the states already.

How did u get. 4.3. I still don't have it and have tried both PC companion and ota and nothing I check every day

Updating now on my unlocked US Z1. No update when I checked on the phone, but connected to PC companion and it popped right up.

This is true, but I couldn't get it OTA. It makes sense in a way, assuming OTA updates actually happen later down the track, somewhat like Google's updates being "WiFi only until ". I think they do, because my Xperia T got Jelly Bean OTA (I was late to the party)

if you update via pc:


That should solve the error

Damn, don't say that in the forums. You will get banned, beaten up, burned at the stake and throw to the darkest depths of mordor

In no particular order

Dammit man, I am a commenter not a clairvoyant!

Pretty much.

People don't realize the Nexus devices aren't built to be speed demons. They're rarely optimized as well as a non-nexus device.

Why? They're just there to demonstrate the new OS.

That's why you see people loading the dalvik lib from the Moto X onto the Nexus 5.

Moto optimized and tuned that thing.

Nexus devices are awesome for the money, and people should remember that fact. They're not the end all device for everyone, nor are they ever perfect.

Sony's blog post says they'll announce the rest (T, TX, V, Z and Tablet Z(?), and whichever else) as they come soon.

Can't edit comments from the app. Darn. It also seems that the Small Apps panel is one sliding row, rather than being paginated.

After waiting a week for the over the air update to become avavailable on my Z Ultra, I decided to look for another way to update. I thought that maybe by using the Sony PC Companion program I could update early, and it worked perfectly. If you're still waiting on an update due to carrier and location, try downloading the Sony PC Companion!

How do I disable the "update via WiFi only" on my Xperia Z1 phone? I don't have a WiFi connection and would like to update using mobile data. I keep getting the messages "Pending network" or "Download is only available via WiFi"

I got a new Xperia Z1 in Germany two weeks ago. Even though Sony rolled-out 4.3 and it says on their website that it is available I still can't get the 4.3 update. Even with PC Companion it updates to 4.2.2. My roommate has the same phone and already running 4.3 - mine is still stuck at 4.2.2. HELP!
