Looks like a decent phone for the price, really good camera. The reviews are ok, not great as they deem the phone as not really aimed towards a particular genre of people. But the specs are good. Picked one up last night for the wifes birthday.
5 inch Full HD curved display
23MP camera with Predictive Hybrid Autofocus
13MP front camera for low-light selfies
Qualcomm Snapdragon 650, 64-bit processor
Android 6.0.1 Marshmallow operating system
From the questions in the Amazon site, looks to be the 3GB RAM 32GB storage model.
