Last month an Android 4.1.2 Jelly Bean based ROM had leaked for the Xperia S. This month, the Xperia P joins the list with a JB base firmware leaking for the handset.
Like the Xperia S JB firmware, the Xperia P JB firmware is not good enough to be used a daily driver since it lacks basic connectivity features including mobile data and Wi-Fi. However, the firmware does provide a glimpse of all the features that Sony will be bringing to the handset with the update including Clear Audio+, its new enhanced suite of Media apps (Walkman, Album etc.), slight UI refresh, updated Camera app, a new lock screen and Xloud.
Sadly, Sony won’t be bringing its Small apps feature to the Xperia P, as originally seen on the Xperia T and Xperia Z. Sony will not be updating the kernel of the Xperia P with this update as well, which might not go down well with the developers.
Even then, the Android 4.1.2 update will bring quite a lot of new features to the Xperia P, which is not bad considering its a mid-range phone. Sony is expected to roll-out the Jelly Bean update for the Xperia P sometime in the next couple of months.
