Nowadays mobile phones are getting so hyped that need for proper knowledge of it is important. If your budget is below Rs.7000/- then you can buy an android or an windows phone.
Try Samsung Galaxy series or the Sony xperia mini version. If you can afford above Rs 15000/- then you can go for big screen phones like Samsung galaxy Note or duos.
If you want game ready phone, I suggest Sony phone’s since they have snapdragon processor. Samsung is powerful in terms of videos and images .The camera is flashy.
If you want very cheap phones in > Rs 2000/- but < Rs 5000/- then buy Micromax . Micromax has ability to topple smartphones.
If your budget is exceeding Rs 40000/-, then you can join the elite group of Iphones. If you want latest smartphone go for Iphone 6 or 6+ for Rs 70000/-. But Iphone has IOS operating system inbuilt and there is nothing an Iphone can’t do.
If your a businessman and looking for windows phone, I highly recommend Nokia. Nokia with its new amazing features is a complete package. Given the sales in India of Nokia is declining and Samsung taking over the android market.
Iphone has its own patented features, which itself makes it unique.
If you want a digi- camera type phone go for 41 Mp camera Nokia.
Although Samsung has same outlook body for most phones, they all differ by just 2 features. So be smart enough while you buy.
Don’t buy Motorola phones because their battery backup sucks. If you want long standing battery, take a low RAM phone like Samsung pocket.
Google is working towards updating the next version of operating system so as to maximise battery and layout but that will definitely in new phones.
Do research well before going.
