Hi friends I am share my experience on sony m5 dual. This is best phone presently I am using. This is best camera . It have best design glass with back glass coating. Sony xperia m5 have some problems such as battery backup, screen will not will seen in sunlight. Now I will tell about battery backup. In sony xperia m5 battery draining in 6 to 9 hours. But on the box of the 2days standby. I have asked to sony company members they said that andiod problem you can get corrected in the upcoming andiod version . The another problem is screen is not clearly in sunlight . It happens due to presence of water resistance program in the phone. Still no sony xperia m5 is not updated to android 7.0 .
