Sony had released a firmware for Xperia SP last month, to fix bugs which were reported after the device got updated with v4.3 Jelly Bean OS. And now, a new report has surfaced that the company is prepping to roll out another stability update to the 2013 mid-range smartphone.

A new firmware (build number: 12.1.A.1.205) slated for all three Xperia SP models - C5302, C5303, C5306 - has reportedly received certifications from PTCRB, a North American Cellular Operators forum.

Technology website XperiaBlog claims the software is expected to fix the flickering screen glitch, which was reported just after the phone got updated with software (build number: 12.1.A.1.201). The bug makes the screen flicker, quite distracting to really focus on the text or watch videos/images on the phone.

As of now, there is no word on when the new update might released but if the recently leaked Sony's internal documents are to be believed, the company is scheduled to roll out the v4.4.2 KitKat OS to Xperia SP and other devices (Xperia SP, E1, M2 and T2 Ultra) next month. So it is possible that the company would release stability software to Xperia SP, to tie all the loose ends before pushing the latest Android.

This year, Sony has been facing a lot of flak for releasing half-baked software update to flagship devices as well; In March, the company released KitKat OS to Xperia Z1, Z1 Compact and Z Ultra but soon, the smartphone owners began complaining about reduced audio quality in the phone's speaker, notifications sound, fast battery draining issues, weak Wi-Fi connection and other minor problems.

Then, Sony was forced to release a statement, acknowledging the issues in the OS update and vowed to push out a software patch to fix the bugs.

Earlier this week, Sony started rolling out KitKat update to a handful of devices - Xperia Z, ZL, ZR and Tablet Z.

The new software (build number: 10.5.A.0.230) brought in improvements to native apps like Messaging, Email, Smart Social Camera, battery STAMINA Mode and multi-media applications - such as WALKMAN, Album and Movies with Sony Entertainment Network cloud service integration and also PlayStation 4 compatibility - with same sleek launch animation and live wallpaper across the lock and home screens, as well as enhancements in security, user-interface, performance and more. There are no reports of bugs in the update so far.
