A very small update may be heading to the LTE variants of the Xperia E3 (D2203, D2243, D2206). The PTCRB website shows new firmware build number 18.4.C.2.14 that has been certified, which compares to the current build number of 18.4.C.2.12. We’re most probably looking at small bug fixes. If the update does get released we’ll keep you posted.
Thanks dif wwh!
