Sony Xperia M2/Aqua need a update! Please Sony, update it... I've other problem! Change ISO value don't have effect.... Please Sony, fix camera of Xperia M2!

Edit: After a reset, if updated to *.181, will improve quality and ISO.. But never as kitkat! (ISO bug already have in Kitkat, but not notable..)

If Sony update Xperia's M2 to Marshmallow, I believe that these problems will disappear... I hope.
