Okay I have been usinh this phone since 4 months and honestly I havent faced any problem yet.
As I mentioned useful for old aged because it is very simple and I think everyone can learn to use it if someone is a old aged person or newly using smartphones.
The camera is qualtiy is little bit low but as compared to its price.its worth it.
It also consumes very less data and can savw your money too.
But theres a problem that you cannot use other sim cards in it.I mean you can oy jio sim card in it as it is a jio phone.
I recomment this phone to everybody who wants a good phone in low price
