10Sony Xperia Z5.

The Xperia Z5 is Sony’s 2015 flagship and the last model of the Z series, replaced by the X series in February 2016. When it launched, it pushed changes in the camera, offering a new 23-megapixel sensor that is now seen in the newer Xperia X models. It’s a good performer, but it is hampered by slow software, making the experience a little lacklustre.
There is plenty of power in the Z5, the water resistance that Sony is known for and it’s a handset packed full of tech, as well as plenty of customisation from Sony. The design isn’t quite as premium as you’ll find elsewhere however, meaning the Xperia Z5 is overshadowed by more exciting rivals, and Sony’s software is the biggest bugbear.
