Samsung Galaxy J2 is a small budget good quality phone. But in this phone are many problem.First it’s system memory is very low.I can not install basic app neither I can update basic pre-loaded apps like Chrom, Googel App, Google Drive etc.I can’t instal games and other software because of very low storage. This device is not KNOX enable and not a theme store. But you can choose 3 pre installed themes except default touchwiz theme. The good thing is that it is not having the annoying filpboard briefing pane on the left screen.The Galaxy essential widget and quick connect on notifications panel.
