a phone with better specs than Nexus 5 for half the price, do you really have to ask that question?
i am paying considerably more for it because i have to import from china, and i'd say it is still worth every penny.
for that kind of money i would only get a low-midrange device in my country (except i would go for a subsidized one with provider lock)
as with all electronic devices, there are probably going to be duds, as even the best QC will not test every single device. happens to the best. should not be used to judge in my opinion, except there is a high number of failing devices.
you have local service centers, so even that would not be a problem.
i envy you people in India, and still there are some *peeep* complaining.
check your alternatives in that price range and then tell me if you found something better?
sorry for the ranty post... i certainly don't mean to offend anyone.
don't worry too much, just buy one and enjoy it.
