If you are planning to buy a cheap secondary device then go for Redmi 5A 16GB varient not this one because you can get Redmi 4 16GB instead Redmi5A 32GB. Why?
Redmi 4 is got more promising hardware like snapdragon 435 instead 425
Redmi 4 has metal body instead Redmi 5As plastic body
Redmi 4 has Fingerprint but Redmi 5A doesnt.
Battery is 1000mAh extra in Redmi 4
Charging speed is too slow in Redmi 5A and it took almost 2hr20min to fully charge from 5% to 100% with the supplied charger.
So if you really want a good secondary device then buy Redmi 5A 16GB varient that costs around 5k, but if you have 7k budget dont buy Redmi 5A 32GB, instead go for Redmi 4 16GB version. It will serve you better.
