This the best phone which is presently I am using.This is best in camera.it have a best design with back glass coating.sony xperia m5 have some problems such as battery backup, screen will not well seen in sunlight.now I will say about battery backup.In sony xperia m5 battery is draining in 6-9hours.But on the box of the it is shown as 2 days standby.I had asked to the sony company members they said that it is the andriod version problem you can get corrected in the upcoming andriod version.the another problem is screen is not seen clearly in sunlight it happens due to the presence of water resistant program in the phone.still now in sony xperia m5 is not updated to andriod 7.0
