1. Think a little about design Design is the most important thing in the case of smart phones. There is nothing to seek advice from anyone in this regard. It is a matter of one's own taste. All the smart phones in the market have eye-catching designs. Again there are different cases to make the phone more attractive. So it is better to choose the design according to your personal needs and tastes. 2. Weight and Feelings No one bothers about this feature of the mobile phone set. There are so many types it's hard to say. The larger the mobile phone set, the heavier it usually is. But before looking at all this, you will notice whether the phone set has a battery. Because the weight of the battery is quite. 3. The size of the screen is not everything. Everyone sees the size of the screen when buying a new mobile. Now big screen mobiles are more popular. However, if you want to carry easily, small screen mobile should be taken. Mobile phones with four-inch or four-and-a-half-inch or five-inch screens are also in high demand. 4. The quality of the display The quality of the screen is a very important issue. The best quality display is 1080p (1920 x 1080 pixels). However, the price of this display phone will be quite high. You have to see if the picture can be seen clearly from different angles. The display of standard mobile phones is less than 720p. 5. Operating system There are several basic operating systems. Android is the most popular system today. Meanwhile, the iPhone has iOS, the latest version of which is iOS 7. Again, the number of fans of Windows operating is not less. Choose the one you like. Because all the activities of the whole phone are determined based on the operating system. . 3-G or 4-G 3G connection has just been introduced in our country. The speed of data connection depends on it. Four-G gives faster connection. Mobile phones that can take 3G connection are better for smart phones of this era. . Battery power Battery power is determined based on what the mobile phone looks like. However, mobiles with large screens consume more battery power. So a strong battery will be needed to keep the mobile running for a long time. 3000 mAh is now the most powerful battery in the market. . Keeping software updated The phone's software is constantly being updated. If you also keep the software of your phone updated then the device will work beautifully. Otherwise Nana will adulterate to do any work. No new apps will be supported and the phone will slow down. 9. Try to get 2 GB RAM. RAM will speed up the activities of the phone. If you spend a lot of money to buy a phone, one GB of RAM is enough. However, it is much better to arrange 2 GB with a little money or change of choice. Modern mobiles are coming in the market with up to 3 GB RAM. 10. Camera resolution is not very important. Camera resolution is not one of the most important issues. Because the job of taking good quality pictures is with the camera , not the mobile phone. High resolution mobile camera pictures are a bit better. But it's not like the camera. So it is foolish to look for camera resolution on the phone except for other things.
