This mobile is very worst compare to all mobiels.
Becouse donot have a extra internal memory.
And donot have a ram( random access memory) is very low that reson very slow in working and quickly hanging.but strong phone in india and samsung service centers are established in all cities .
At care to give a mobile to service is very slow process . This mobile dont get install all apps
And donot support for games
Any type of games once play mobile will be switch off
And performance will be slowly decreased.
