Hi jery welcome to pinstack, glad you joined us.
I use a $13 dumb phone due to its unmatched battery life and reliability, really don't need all the fancy stuff. Im old school. Though ive got a Lumia 520 and Samsung galaxy s2 that I almost hardly ever use.
Ive also got a nokia 301 ( a device with a numeric keyboard that runs on nokias asha or symbian software)
Ive also got an old Samsung star and htc snap locked away in my cupboard.
