I used this phone for almost six monts. Here are some pros and cons of the phone.
Pros:
Good display
Compact enough size
Snapdragon 615 is a quite capable processor
Awesome sounds output due to dolby atmos.
Decent build quality
Cons:
Pathetic battery. Does not last even 18 hours with moderate use.
Phone gets quite heated with a little heavy use.
Volte was not there at first but they provided a update and enabled hd calling. But there were problems in call a few times.
The UI was pathetic.
No regular updates were provided.
