Besides releasing 4.4.4 KitKat to flagship devices, the company has also announced the roll-out of Android v4.3 Jelly Bean OS to 2012 smartphone Xperia V.

"minor #JellyBean 4.3 firmware rolling for #XperiaV – brings bug fixes, performance & stability improvements & more!" read the Sony twitter post.

According to the company, the new update brings in improved user experience, enhancement in battery life and software performance.

Sony, despite rolling out new software updates quickly (compared to rivals) to smartphones, got panned by device owners, due to bugs in the firmware.

In March, the company released KitKat OS to Xperia Z1, Z1 Compact and Z Ultra, but soon the smartphone owners began complaining of reduced audio quality in the phone speaker, notification tones, fast battery draining issues, weak Wi-Fi connection and other minor problems.

Later, Sony was forced to release a statement to acknowledge the issues in the OS update and owed to push out a software patch to fix the bugs, before releasing the stability update in April.
