Samsung galaxy s duas 2 is little old type phone this phone configuration is low means very low this phone have 746 MB Ram and 4 GB internal memory but you have to extend with 32 GB external memory this one has operating system is 4.2.2 Jelly Bean and its camera 5 megapixel back and 0.3 megapixel front.
I never suggest today’s generation is never buying this phone if you are fresher in Android so this phone is only for you
