I have oppo neo 7 mobile. I am using this Mobile handset last 4 or 5months. 5.1.1 Android version, 1 GB Ram, 1.03 GB rom total internal space is 16 GB. Qualcomm Quad processor. Lookwise mobile handset is very good. Camera of this phone is quiet good but only front camera not rare camera. Other functions like display, Sound quality, video quality, recording quality not very good. If I m saying about hanging problem yes the handset is hang a lots of time. Because of hanging problem mobile running very slow. I am frustrated about it’s hanging problem. Oppo neo 7 is not much good handset.
