Sony Mobile has updated the Xperia L1 with a new firmware update that moves the build number from 43.0.A.5.79 to version 43.0.A.6.49. The latest firmware gives the handset the 6 November 2017 Android security patch (from August 2017 previously). There appear to be few other changes noticed. The Android build remains on version 7.0.
