I have been using this phone since 1 year and its been a mixed bag. Its a costly mid segment phone but the cons do not make this phone worth it.
Pros:
Big screen
Sleek(but for touch you need a hard back panel or a full cover to provide support)
It does not have any external memory slot. So all your data/apps are stored in a single internal memory. This makes it easier to function as there are no issues of internal memory being full
Cons:
Heats up instantly
Battery drains in seconds. If you are using facebook app or even just clicking around reading messages the battery drains 1% every 2-5 minutes. So the phone has to either be constantly charged or if you are on an app for an hour the battery will go down to 70-80%.
Camera crashes suddenly for no reason during or even when you are starting the app. You need to restart the phone and try again
You need to remove all notifications from the settings or else there is a lag of 5-10 minutes when you start your wifi/data. It takes a long time for all the apps to update themselves or provide notifications
