every smartphones must be supported for atleast one year and more and within this period every  Android OS upgrade that realeased by google must officially realease by manufactures.  since xperia m was realeased in August 2013 this smartphone must get kitkat soon.

beside that there are some bugs such as GPS connection and LED notification Not functioning properly in STAMINA mode &... we expect to get fix in this update.

we are all the fans of sony and we want to taste kit kat in our smartphone...
