I most like a smartphone of Samsung near 25000 is Samsung Galaxy A8. It's the slimmest phone of Samsung. It's giving us 5.7inch display with gorilla glass 4.
It's also dual sim supported mobile. Also, support 128GB of external storage. And it's internal storage is 32GB.it's giving us 2GB of RAM and it's enough.
It supports OTG also. Its battery backup is awesome.it has 3050mAh of strong battery backup. Samsung Galaxy A8's one feature I don't like is that we can't use sim2 and sd card at a time.
So I am giving 4.5 stars out of 5 to this device.
