Sony Mobile has released a new update with the build numbers 26.1.A.3.111 and 26.1.B.3.109 for Xperia M4 Aqua and Xperia M3 Aqua Dual respectively. Dont get too excited, this is not marshmallow and its just another bug fix update for initial Lollipop 5.0. So this will replace the previous build numbers 26.1.A.2.167 and 26.1.B.2.147 respectively. Update is avaiavle for many regions on many variants. So be patient. No change-log has been released yet. So feel free to share some info about the update if you've got it.
