Sony just pushed out a new firmware update (build 11.3.A.3.1) for its Xperia E Dual C1604/C1605 smartphone, only a day after outing a similar update (11.3.A.2.33) for the original Xperia E. Apart from a bunch of minor bug-fixes and performance enhancements, this firmware doesn’t bring anything new – it still carries the same v4.1.1 JellyBean OS. Rest of the firmware details along with its direct download links are given below.
