Sony Xperia SP is among few selected smartphones eligible for Android 4.4.2 KitKat. A new firmware spotted running Android 4.3 Jelly Bean to fix bugs while factors can impede Android KitKat update for the device.

Under Investigation

After being considered before for Android KitKat update, Sony Xperia SP got tagged as "under investigation." If you visit the Sony Support Web site for the smartphone, Android 4.1 is the factory OS, Android 4.3 as the current version and Android 4.4 KitKat future update subjected to investigation.

Xperia SP joined Xperia T, TX and V on the same status being investigated by Sony Mobile if eligible to get another major software update after Android 4.3. But Xperia SP is a lot fresher compared to T, TX and V for it was released in April last year and the update support will end by October 2014.

Delayed Firmware Update

Sony Mobile skipped Android 4.2.2 in favour of Android 4.3 for various Xperia smartphones including SP. However, the update rollout happened very late compared to the expected release which should have happened on December 2013. Android 4.3 firmware for Xperia SP underwent several changes, probably because of various bugs found.

PTCRB approved four different Android 4.3 firmware builds in several months from December 23rd to January 29th 2014. Sony pushed the firmware update during the mid-month of February 2014.

Apparently, some major bugs were found on the latest Android 4.3 Jelly Bean for Xperia SP. 12.1.A.0.266 is the current available software for the device and owners have found certain problems such as constant lighting up of the notification illumination bar during voice calls and occasional crashes from apps that can only be fixed by reinstalling them from the Play Store.

French network carrier SFR approved the new firmware 12.1.A.1.192 Android 4.3 Jelly Bean and said that it would be released a few days ago. Unfortunately, it hasn't been rolled out to fix several glitches on the initial Android 4.3 update.
