Many happy owners of smartphones often face any problems after the purchase. It is not always possible to notice a factory defect during testing in a store. And many do not even know how to properly check a smartphone before buying and what you should pay special attention to.
Of course, the manufacturer gives a certain guarantee for many smartphones. However, it happens that it is short-lived or, in some cases, does not apply to everything. It is also rarely about any kind of guarantee when buying from hands or in some online stores.
In order to avoid many problems later when using a smartphone, it is worth checking it carefully before buying.
General smartphone operation and equipment
To get started, insert your SIM card into a new device and try to contact someone. This will test the quality of the connection, the spoken and "auditory" speaker. Then insert your memory card into the slot provided for it. And try, for example, to play a video from it. This way you can check the picture and sound quality. Then check how the headset and charger are working.
Check your smartphone camera
Get your new device, turn on your camera, and take a picture of a white piece of paper. Take a close look at the resulting image. If you notice that a green, blue, black or red dot appears on a white background, this indicates a knocked out pixel on the display itself. Do not worry too much, as this will not affect the performance of the phone. However, for the money spent, you always want to get a smartphone in perfect condition.
Check Wi-Fi signal
Turn on Wi-Fi on the new device and move 3-4 meters away from the modem. If the phone has lost the network, then you have no contact with the Wi-Fi antenna inside the smartphone. If there are no problems with the connection, go to the Internet and try to open something or even download there. It is also necessary to check the GPS function. The smartphone should determine your location as accurately as possible. If possible, run similar programs somewhere on the street for the most accurate result.
Battery check
Of course, if the smartphone is new, you shouldn't worry too much about the state of the battery - everything is in order with it. However, if the model is purchased from hands, it is worth taking a closer look at the battery. More often than not, the area next to the battery will receive a white sticker. If you notice that this area is red, then moisture has entered the interior of the device.
Check motion sensors
Each smartphone has many sensors that are responsible for movement. And when buying, you must definitely check them, because the degree of convenience of working with the device depends on this. To do this, launch the gallery and open any picture. After that, turn the smartphone in front of you in order to check how quickly and correctly it reacts to your commands.
