Lumia 430 its having 1gb ram equivalent to 2gb in android and ram of 8 gb. fully protective mobile. what I love in lumia is they are not less than ios because they too having the same features of ios. ios casts above 30, 000 whiles lumia provides the same protection, personal assistant ( ios-siri) ( wp- cortana) . ios mostly dont hang such as wp dont hang.this is best only minus for lumia is heating of phone. please take care of heating for next releases by lumia
