Xperia arc S firmwareA new firmware version (4.0.2.A.0.42) for 2011 Sony Ericsson Xperia devices was certified around 10 days ago. We were recently speculating what this update may be, but it looks like it only offers some minor bug changes.

We just loaded up this firmware onto an Xperia arc S and it is still running Android 2.3.4 rather than a newer version of Android. From what we can tell, there are no tangible differences to the older Android 2.3.4 firmware. If we do find anything different we’ll update this post, but for now, there’s nothing to see here.

    Well in your case your lucky, that’s expected since the arc has been in the market for several months now, but in my case, i have the ray, and it’s still on 2.3.3! I’m waiting like hell for the 2.3.4, then suddenly this news pops out. Ugh! how frustrating could SE be???

    What do you mean no sound when unlocking phone? Are you referring to the selection/touch tones on your xperia? On what particular unit is this exactly? I’m having issues with my Ray too…. an almost unnoticeable sound whenever i’m navigating through menus/sub-menus.

  • It’s available in Philippines. If your Update App says you have the latest software, try connecting via PC Companion.  Mine worked that way.

  • Kevin

    Right. However, if someone as inexperienced as I am to revert to the previous firmware to update it on the official, how could I go about doing this if you know?

    Thanks for the input.

  • Ptizamarabu

    Neo in Ukraine, still have 2.3.3 (

    In my opinion, the update did not do anything but have done damage to my POP3 Email.  My incoming email is being deleted as soon as it has been read  in a split second.  Say, if I wanted to reply, I was not given enough time to reply the email that just arrrived. It is frustrating for me to experience such a problem. All functioned smoothly before  the update and after updating everything went belly-up.  What a tragedy?

    Xperia ARC upgraded right now here in Spain but it seems that nothing was changed ¿?
