The bug-fixing update for Sony Xperia SP smartphone, which was scheduled to be released by March end has reportedly been delayed for a month, says a new report from France.

French network carrier, SFR (Société française de radiotéléphone) has released a statement that smartphone maker, Sony found some anomalies in the FOTA (Firmware-Over-The-Air) stability update (build version: 12.1.A1.192) and would require some more time to rectify the code, hence the roll-out process has been postponed to 21 April.

The new software was supposed to improve performance, stability and UI optimization as well as enhance the entertainment centric apps (Walkman, Album and Movies). Now it remains to be seen, if Sony would just fix the issue and release the firmware with same code (12.1.A.1.192) or come up with a newer version, reported Xperia Blog.

Xperia SP received the new Android v4.3 Jelly Bean OS update last month and Sony had vowed that the company was working out ways to release new OS firmware v4.4.2 KitKat later this year.

Last week, Sony rolled out the chocolate-wafer flavored Android OS version to a handful of high-end devices- Xperia Z1, Z1 Compact and the phablet Z Ultra and the company has promised to push new updates to Xperia Z, Xperia ZL, Xperia Tablet Z - and Xperia ZR - from mid-Q2 and later to recently the launched - Xperia T2 Ultra, Xperia E2 and M2 series handsets.
