I got this v7+ as a gift of my brother and used almost 5 month and I just awkwardly astonished about this product, because it got 1.8Ghz processor and 4 Gb of RAM, and my phone only installed with 7 apps other than inbuilt and FIfa game too, and whenever I open and plays atleast 10 minutes mobile shows insufficient memory, close the app.! I just wondered about that because I played fifa game on 2GB RAM. Phone without any hesitation or problem, but this phone has 4GB RAM and hangsup. Why! ?
