The Sony Xperia P (LT22i) Android 4.1.2 Jelly Bean test firmware, designed for developer devices has leaked. DooMLoRD from xda-developers has managed to boot the firmware to consumer devices and has made it available to all. The test firmware has version number 6.2.A.0.399 with kernel version number 3.0.8 (DooMLoRD says that the kernel will not be updated to a newer version on release).
The firmware has GSM disabled so you won’t be able to make calls, but if you want to preview the firmware, you should be able to give it a test run with both Wi-Fi working and GAPPS installed. Further details can be found at the source link below.
We have included some screenshots from the update. You’ll notice that the camera app has been updated. Unfortunately Small Apps will not be included in the JB update, but Stamina mode will be present. On the audio side, Clear Audio+ is included along with Xloud, the equaliser and Clear Phase. The latest media apps are also present along with the new lock screen.
Thanks Ben, MScorpionZ and Saurabh!
