J7 is vary good phone . It looks very pretty . Battery is very good . J7 is very very good phone comparison its price . Adding of many new new updates the mobile use very easy . But j7 camera is very bad similarly Grand max . This mobile has many apps that are very importent but s bike mode has not importent for me . It is useless for me . The app which is useful and importent for me that is U power saving app . I like it very much . Because when on the u power saving app the mobile battery charge lefted many short . Otherwise , j7 is vary nice & good phone . Moreover j7 has many facilities . So , I like j7 very very much than Grand Max
