Don’t fantasize too much about the ads
It is foolish to listen to the salesman’s offers. Because any of them want to sell a lot of products to race for sales, so winged advertising is inevitable.
The way to avoid this “magic maze” is to ask the consultant to provide parameters and technical details for your own reference. In addition, you should learn about the product carefully before buying to avoid the case of buying the wrong smartphone.

Do not race for configuration
Some young people who know technology often have the habit of racing to configure when buying a smartphone, in fact this is not necessary. Of course, the more powerful the device, the smoother and more efficient browsing the web as well as running some applications. However, do not ignore some machines with mid-range configuration, cheaper price but still very good speed.
Moreover, focusing on the configuration race will make you feel outdated, costing you a lot of money to invest in a new one.

Determine financial viability
This is the most important step when you decide to buy something. The amount you can afford to help you determine the segment and price range that you are aiming for. This will make you less confused when standing in front of too many smartphone brands with diverse prices.
There is a mistake that smartphone buyers often make that is the concept of “the more expensive the better”. The truth is not like that, to evaluate product quality, you have to rely on many other criteria such as durability, utility, reputation …

Consult an expert before buying
Doing this before deciding to “live” with a smartphone, you will have the basic knowledge to evaluate product quality. Experts here can be people who have used the product and have experience. It’s very simple, you just need to go online to search for reviews to get more opinions.
However, be wary of PR tricks with reviews of some mobile phone companies. Do not rely too much on a single review, read a lot and summarize the experience for yourself.

Battery life
Imagine you have the fastest car in the world, but it runs out of gas. That means you can’t go anywhere. Phones too, when the battery runs out, it’s like you’re holding their model.
So, choose a phone with a battery life of at least 2.000 mAh and can talk for 15 hours, just how much will help you use it comfortably for a day.

Camera
You can search for posts on the internet about the phone’s camera reviews. See the images captured by this camera as well as its video recording capabilities. It should be noted that reviewers often reduce the quality of images to facilitate posting.
As for the image, you should carefully check if the image is burned, wrong color, out of focus? How is the image produced in low light and bright enough? About the video recording ability of the device you can find on YouTube by entering the device name with the phrase “camera test”.

Memory storage
Now perhaps the standard for all memory capacity for all phones is 16 GB, as we can hardly do anything with a phone with only 8 GB.
Because with the current operating systems that have taken up 5 GB of internal memory, we have 3 GB left to store and install applications. So when buying a phone, choose one with at least 16 GB of memory.

Screen resolution and quality
When you turn on your phone, the first thing that communicates with you is the display. So companies are very interested in this area. There are two factors that determine the display quality of a monitor: resolution and screen technology.
Resolution is the set of pixels inside the screen. When you bring your eyes close to the TV or computer, you will see very small squares, called pixels. The more pixels the screen has, the clearer the display.
Apple has applied increasing the pixels of the screen to the point where users can’t see them for Retina displays, making text or images more vivid. When buying a phone, make sure your phone has a resolution of 1.280 x 720 pixels or higher.
You also don’t need to worry too much about screen technology. Because now companies are doing well in this area. And only the most obvious difference is the LCD and AMOLED screens.
If the two variants of LCD are IPS and S-LCD for accurate colors and great viewing angles, then in AMOLED screens are flattering, vibrant colors, showing deep blacks but sometimes does not give accurate color.

Design
From the removable back so that the battery can be replaced, companies have gradually switched to a monolithic metal design like Apple and made it the norm at the moment. Or the latest is the detachable and modular design of the LG G5. But design doesn’t seem so important to many people because they drop it all day and knock it over.
So the main advice is that if you are a picky person you can choose phones with luxurious looks, unibody aluminum design, iPhone is an example. And if you are not too careful, then a durable phone is a good choice.

Choose the right operating system
IOS, Window Phone, Androi or Symbian… these are all quite popular operating systems in Vietnam and around the world. Smartphone is a smart phone with many pre-programmed utilities, so choosing the right operating system is essential. If you are someone who has a lot of money and likes to experience famous brands from Apple, iOS is the smooth, quality operating system for you.
But if you can’t afford it, you can target many other brands like Windows Phone or Android. Beautiful interface, strong customization ability, extensive configuration and diverse price range are the advantages that make these two operating systems dominate many markets. Thus, depending on financial capacity, needs, and preferences, users will choose the appropriate operating system.
