Oppo f1s is one of the best mobile available in the market.its back camera and front camera are really awasome.battery back up is good.it run along with apps almost 1-2 days.it processor is great no hanging problem at all.the feature I like the most is to do chat while watching video it make video window precise as you want so that you can do other work like check fb, whatsapp, instragram etc.other unique feature is taking screenshot and hiden picture taking mode.minimal heating if you are using gps or playing games.4gb ram is sufficiant to use feel.dual network fairly working fine.all features of this phone are great.is you are a selfi lover then surely go for it.really it is a good mobile.
