Earlier people used to buy Nokia mobile phones when Android operating system was not launched. But after the launch of Android operating system by Google, the purchase of mobile phones with Android operating system increased. Out of the three brands that you discussed above i.e. SAMSUNG, NOKIA and APPLE, only SAMSUNG uses Android operating system for its phones. Nokia runs on its own operating systems S40, S60 and Apple runs on its own operating system.
Also the product quality of Nokia mobile phones is better than Samsung therefore the price range of Nokia mobile phones is slightly greater than that of Samsung.
But nowadays the purchase of Samsung mobile phones is increased in India. Samsung is providing more features in less price range as compared to Nokia. And obviously Apple's product is best among the three but the price range of Apple mobile phones is very high as compared to Nokia and Samsung mobile phones. Therefore its selling is least among the three.
Today the most preferable mobile handset brand in India is Samsung. Most of the customers are preferring Samsung phones. If you need a good brand mobile phone with Android operating system then you should go with Samsung. If you are looking for a tough mobile phone with good battery backup and long life then you should go for Nokia. And if you can invest around 40k for your mobile phone then you should go for Apple. In Apple you will get all the features that a mobile phone can handle.
My suggestion is that if you want a mobile phone below a price range of 15k then you should go for Samsung, if your price range is between 15k to 35k then get a Nokia mobile phone and if you are having a budget of around 40k to invest on a mobile phone then go for Apple.
