I purchased this phone about 18 months before. Now I am using this phone from 18 th months. It has 2GB Ram, 16 GB internal Storage, 5.5 inch screen, 13 and 5 mp rear and front camera, and 5000 mah battery. By the specification I think when I baught the phone is very good but when I use it after 8 th months it seems problems. Network automatically disable, automatic switch off, and battery service going down. Speaker of this phone is medium. After using it 18 th months I suggest it not so good phone as it features.
