You don't have to buy a smartphone all of a sudden. Phone should be bought only after seeing-hearing-understanding many things. Apart from that, the screen size , RAM and display will also depend on how you use the phone . Before buying a phone, keep in mind these tips: 1. If the budget is much higher , it is better to buy an iPhone. But not cheap secondhand or much older version. The updated version costs a lot. If you do not have money in your pocket, buy Android. 2. Needless to say, not buying a BlackBerry. Just think twice before buying a Windows Phone. First of all, there are not many apps in the Microsoft Store and if you have to buy a phone just to make a phone call and pick up the phone, then why buy an expensive smartphone , it is better to buy a normal phone. 3. The first thing you will see before buying a phone is the processor. A good processor means the phone will be superfast , the phone will not hang while playing games and photo editing will be quick. The Snapdragon 800 series processors are medium range phones but the best are the Qualcomm Snapdragon 620 and 610 processors. In the case of iPhone, 64 bit , A9 chip is the best that is in iPhone 6. 4. Now that the Forge data connection has arrived in India, it is wise to buy a phone that will support Forge if you buy a new phone. 5. RAM is another very important issue. If you have a strong pocket, it is better to buy a phone with 4 GB RAM. Otherwise at least 2 GB of RAM. Because now all medium range phones have 2 GB RAM even in iPhone 6. . After RAM , Forge , processor, you will see the display. Try to buy a phone with AMOLED display. Even if you stand in the hot sun, you will see the screen clearly. Quad HD 2560 x 1440 pixels phones are much more expensive. If you buy a medium range phone, the resolution should be at least 1280 x 720 pixels. . After that you will see how the storage is. Never buy a phone that does not have expandable storage. Those who can use the smartphone properly , they download a lot of apps. It takes a lot of storage space. If you need to use a micro-SD card , keep that option open. Buy a phone that has at least 16 GB of internal memory. . It is better not to buy a phone without front camera and LED flash. Now the medium range phone has a standard 13 megapixel rear camera. The camera of iPhone 6S Plus , Galaxy S8 , Galaxy S8 Edge , HTC 10 is very good. More fun LG G5. It has two types of rear camera settings. One for normal and the other for wide angle shoot. 9. Battery life is another important issue. One of the best Forge phones that can be used for 8 hours of continuous net surfing after a full charge . Better battery life is 3000 mAh. It is better not to buy a phone with a battery life of less than 2500 mAh in a medium range phone. 10. Wi-Fi is present in all smartphones. Try to buy a phone that has Bluetooth 3.0 because if you have this version, the mobile can be connected with the smartwatch. Apart from that, it is better to buy a phone that has GPS so that it is convenient to track the lost phone. And if you have a magnetometer sensor, the smartphone compass will also work. 11. Dolby Atmos Surround Sound is now one of the latest features of smartphones. Almost all of Lenovo's latest phones have this feature. People who watch videos , listen to music or watch movies on their phones should buy a phone set with Dolby speakers. 12. Fingerprint security , shutterproof , scratch-proof screen , gorilla glass , waterproof , NFC tag are all sophisticated smartphone features. As the budget increases , so will all these add to the features of the phone. If you can afford it, then buy a phone that has all these benefits. Many budget smartphones also have one or two of these available.
