Mobile phones are very useful to our day to day life, there are many companies are available for mobiles, but my favorite mobile company is Samsung mobile. The reason is they manufacture very nice and advance mobiles. It is the only mobile company that manufactures more touch mobiles, having all new features at affordable prices.
There are numerous mobile phone companies in the world right now and all the company models are good but to select proper mobile phone one need to understand our needs or requirements then see which mobile company fulfill your requirements and all aspects related to it then choose the best mobile company out of all.
I am currently using the Android OS. But I would like to switch to windows phone. As features of windows phone are unbeatable. And in windows phone I would prefer Nokia. It's Lumia range is the best in windows mobiles.
In today's market i think every android mobile company are good. However, i would suggest you to buy a Karbonn S5 titanium. It is cheap comparatively and yet has all the necessary functions that a android mobile should have.
