Sony Xperia Z1, Z1 Compact and Z Ultra to get Android 4.4 KitKat in April?8
SFR doesn’t mention when the older Xperia Z will get KitKat, only saying that this handset has already received an update to Android 4.3 Jelly Bean. We heard that the Z, which is now more than one year old, may receive KitKat in March. However, nothing is official at this point.
SFR also says that LG’s G2 will get Android KitKat starting March 3 - which is in line with what we previously heard (some G2 versions are already running KitKat anyway).
