The phone is awesome. Its been 3 years and the phine hangs nowhere. Thanks to the stock android and its update to google. But the phone experience is mixed. Sometimes, the phone misbehaves while running any application.
The camera quality is pretty good. Talking about internals it has currently android 6.0, which runs quite good. The speed and vattery life has been increased after the update.
If you are planning to go for new androidphones, go nexis 5X or 6P. When I buy a phone, I never compromise with money.
