No doubt that this phone had brought a great revolution in mobile industry as it was the first mobile with fingerprint sensor but in 2018 this phone is outdated and it will also not support upcoming iOS versions.
The screen size is small and the processor is outdated so it may lag while using high-end applications or games.
this phone has a decent camera but some other phones have better cameras in the same price range.
It is overpriced and you will find better options In the same price range.
The battery backup of this phone is also not good.
So you better buy any other phone instead of buying Apple iPhone 5s
