I can only find two problems with this otherwise wonderful phone; its poor camera and lack of frequencies.
This phone is easy to hold, is lightning fast, has no bloatware, a nice screen, good phone audio, reasonable battery life and very good wifi. It finds the GPS satellites very quickly
It is let down by a poor camera and its lack of frequencies mean in Australia at least, it cannot operate on our largest network nor on the 4G service.
Apart from its two shortcomings I am happy enough with the money I spent in getting a nice fast phone.
