I have used this mobile. After using this I have not good experience after using this mobile. It have 4 gb ram but hang also. It is not very good. It have dual camera and finger print sensor and 8 mp front camera. It has a one good thing that it called a mini dslr as pocket dslr. And in the phone this phone having nought 7.0 powered by Android. It also have a screen split feature. I think for a professional photographer this phone is best because it called mini dslr and also called pocket dslr
