Zgodnie z zapowiedziami, firmware Android 4.1.2 Jelly Bean dla modeli Xperia P LT22 oraz Xperia go ST27 (naturalnie dla niektórych regionów) jest już dostępne. Numer kompilacji: 6.2.A.0.400, firmware posiada jądro w wersji 3.0.8. A to krótka relacja zmian według jednego z użytkowników Xperia Blog:
1. New animation! Boot-up and shutdown speeds are also significantly faster
2. New homescreen with Butter! Higher framerate than ICS build throughout the entire UI (not just homescreen). Also the new homescreen is similar to the one in Xperia Z. That's right -- you can add/remove homescreens and set which one to jump to when you press home!
3. New task switcher that is similar to Xperia Z/V/T, minus small apps.
4. New phone/dialer/messaging apps. White in background. Looks cool but a little out of place with the rest of the (darker) UI.
5. Notification bar pull down redesign. Now with toggles on top, just like Xperia Z.
6. App drawer redesign. Now resembles that of Xperia Z.
7. Stamina/Low-batt modes and Location based Wifi, just like Xperia Z.
8. The Album/Walkman/Movies apps look a little different. I can't tell where exactly as I don't use them a lot.
9. Camera looks identical. No idea about image quality or performance.
10. Clock/Alarm app ported from Xperia Z. Now Alarm, World Clock, Stop Watch, Timer all in one app with cool Sony styling. Awesome! Well actually I never really used this app before so I'm not 100% sure if this is new lol!
11. Both Android Browser and Chrome are available.
12. New FM Radio with very, very cool animations! Again, this is another app I don't really use (I use my Smart Bluetooth Headset for radio XD) so I'm not 100% sure if this is new.
13. Calculator looks a little different. Oh well. 1 + 1 is forever 10. In binary.
14. New "EA Games" app. You get to try a few EA games for free, including NFS and PvZ.
Thank you Sony! It's been worth the wait.
Edit:
15. New lockscreen! Identical to the one in Xperia Z!
Zmiany jak widać bardzo pozytywne. A Wam udało się już zaktualizować Wasze Xperie P, go lub E dual do Androida 4.1.2 Jelly Bean ?
