I have been using a Samsung Galaxy Pocket Neo for the last 3 years. It is a good phone at cheap price, but the phone has probably been discontinued some time ago. The phone packs a 850MHz processor, with 512MB RAM and internal memory of 4GB.
The phone also has a 2MP camera, however the picture quality is not that great. The main problem with the phone is its small screen size(3 inch). Also, the phone starts becoming slow after a few months of factory reset.
Otherwise, the phone is okay for casual usage.
