Full verification of the smartphone before buying

Sometimes it happens that in a store a user buys a completely new device, and at home it turns out that he is not so new. And well, if somewhere the film is not enough, but when the device is turned on and covered in prints, this is completely unpleasant. Below are tips on how to check a smartphone when buying and not to be mistaken. And you should check not only a new or not a smartphone, but also its performance, equipment.

Unpacking

It happens that in the description of the device or on the box they do not write that there are headphones included. If this is so, then even if they are there, they may not reach the buyer. Therefore, initially you need to ask that the purchase brought in a packed box with all factory films, stickers of authenticity. On the box of any phone there are special seals by which you can understand whether the phone was opened or not. Even if a proven store convinces that the film on the box was torn during transportation, and therefore it was removed, and the seals peeled off, it makes you wonder - how the device was carried and stored.

Most often in well-known stores there is a zone of issue, where a smartphone is shown to a customer. Sometimes the seller does not wait until the buyer comes to him after the cash register, and opens the box himself, and then says - just did it. Maybe this is true, but it will not work. Therefore, immediately ask that the box was opened in front of you. Shops have another trick - they ask to sign that there is no problem with the bundling and appearance. You never need to sign until the entire verification procedure is completed, even if they say that it is a formality, or you sign it, and then look. The painting is put at the end, when the device is fully tested for performance.

Even in the fully original packaging of the phone should be carefully check the contentshow the protective films are pasted on the smartphone, it can be seen that before that they had already been peeled off and glued anew. Everything must be very neat. It is necessary to look closely at the details - the film on the display and the back or only on one side. It can not be that two phones packed at the factory were sealed differently.

When buying a phone in an online store, where delivery is carried out directly to your home or mail, you should receive make a photo of packaging, especially if there is any damage. The best option is to videotape the immediate receipt of the parcel and the opening. If any defect is detected, it is possible to prove with the help of the video that it was before opening, and did not appear as a result of the actions of the buyer.

We read reviews and see reviews

If the user knows when buying, which model he will buy, then it makes sense to carefully read the reviews about the device.Meticulous users have studied specific models from all sides and can accurately describe what problems are encountered in the newly purchased device. Kind weaknesses that are characteristic of the party, but still not all. Somewhere, for example, the backlash button, someone has a poorly focused camera, the speaker may wheeze out of the box.

This does not mean that the model itself is unsuccessful. Just such a defect exists, and in its absence one should make sure in the shop with the seller, otherwise, after going home and returning back, one may encounter a lengthy procedure of quality control and other unpleasant things. It’s best to write these nuances on a piece of paper and walk through each item right away in the store - there are no problems, so you can safely buy the device and leave.

In addition to the problems that customers write about, there are a number of things that need to be checked at all times. Below are tips for each item that needs attention.

Authentication

After inspecting the box, picking and appearance of the smartphone, you need to make sure that the box corresponds to the device, and also verify the authenticity of the smartphone. To understand whether the box belongs to the phone or not, you should carefully check the serial numbers and IMEI. You need to check them on the box, on your smartphone, in the technical documentation for the device (not always there).

Important! It will not be superfluous to go into the settings of the device and in the item “about the device” also verify the IMEI and the serial number. All of them must match.

To check the device for originality, you can go to the manufacturer's website and find the item "check the phone." In some cases, the manufacturer asks for pre-registration, so it’s better to see at home how authenticity is checked on the site and go through the registration procedure if necessary. Then the store will just enter the serial number of the device on the site. The site will not only tell you if it is a genuine device or not, it will also provide information about whether the phone was in use. If there is a message that the device’s warranty has expired or is about to end, then this is a bell saying that someone has really tried to give it the appearance of a new product.

Apple

The included Apple smartphone has already started the countdown warranty, and it certainly must always be turned off and not activated when purchased.When buying from the hands of Apple technology, you should not believe in fables about a year or even longer warranty. The procedure is the same - we go to the site, enter the data, get full information about the device and its warranty service.

Samsung

Samsung has no special applications or forms for checking the device, but as one of the methods that are offered on the company's website - Enter the combination in the dialing number: * # 7353 #. A service menu will appear with a check of various items of the device, if all of them work, and the menu has started up, the probability of a fake is very low. Another option is to pre-create an account in the Samsung company services and enter it from a new device. If it worked, then it is not fake.

Xiaomi

Xiaomi Smartphone Check Official Website in chinese, but there you can choose English, so in order not to get into an awkward situation in the store, still study it in advance. The second option is to install on a new smartphone. pro application Mi Verification Tool. It is in the Play Market and will help to quickly check the device for originality, just do not forget that in some stores will install software only after purchase.

In general, there are a lot of signs of a fake - the lack of branded brand applications, poorly translated menu items, the presence of Chinese characters, a blurry picture. It is necessary to carefully examine all this.

Display check

After a visual inspection of the phone, you should check the screen. The test is to understand how well the sensor works, and whether there are any broken pixels on the display.

Sensor operation

Sensor testing is a fairly simple task. It is enough to press the buttons on the screen, look through the pages or enter typing and try typing a message. If all these actions do not cause difficulties, the device responds quickly and accurately to touch, then there is no problem with the sensor. When typing should not be pressed several letters at the same time.

Defective pixels

Checking for pixels is not a difficult task either. Can install one of the special applications, for example, DeadPixelTest, but most often sellers have a strict policy regarding the installation of software on a non-purchased phone. In addition, you need to enter an account in Google Play, which is not always convenient. The store may not have Wi-Fi, or will not want to give it a password. In this case, we proceed as follows.

1. At home we download to the USB flash drive monochrome pictures of different colors - black, white, blue, yellow, red, green.
2. Insert the memory card and run these images one by one.
3. A broken pixel is a bright dot that stands out against the general background. On white and black, you need to look closely at whether there are yellow stripes on the screen. This may also indicate a defect matrix.
4. If the device does not support memory cards, then just remove images from your device via Bluetooth on the checked equipment. Of course, you need to download them in advance to your own device.

Camera check

It is important when buying to check the camera. It is advisable to take a few pictures in the store and, if possible, on the street. Of course, it is difficult to see the defects of a matrix on a bright picture, so the easiest way is to ask the sellers to have a white sheet of paper and remove it.. If the picture is stained, for example, a yellow or purple spot, then something is wrong with the camera. This is not necessarily a defect, perhaps it is simply not the best quality shooting. This point should be pre-read in the reviews. If no one mentions that the camera has problems with photos, then the problem is in the specific device.For comparison, you can ask for a device from the storefront and carry out a similar procedure, and then just compare the pictures. Also not over film a videoand then see how it plays. The picture should not twitch, but the sound should be clear. Again, in the case of cheap devices, nuances are possible, so this point should be studied beforehand.

Sound in speakers and headphones

To test the sound of the device, it’s best to bring memory card with your favorite music and your own headphones. First we check how the music sounds from the speakers. Should not be wheezing, squeaks and other strange moments. Next, insert the headphones and run the songs again. This will help check the headset jack.

Work of communication modules

The verification of the mobile communication module is carried out according to the principle described above. It remains to check Wi-Fi, GPS, NFC, Bluetooth.

Wi-Fi

The first node is checked internet connection. If the store does not have Wi-Fi, then simply distribute it from your smartphone. The purchased device should not only find the network, but also keep the signal at a distance of 10-15 meters.

GPS

GPS can be checked going to google maps. They are pre-installed on almost any smartphone. It is enough to enable the definition of your own location to check this node.

NFC

Contactless payment using NFC is difficult, because you first need to tie up the card. But through this module can transfer file.

1. We take the second smartphone with such a module, it is possible from the storefront, and simply transfer a small file.
2. The second option is to connect via NFC to some equipment in the store. If this is a large store, then there will definitely find a music center with the ability to synchronize via NFC.

Bluetooth

Check Bluetooth is very simple - just transfer the file from one device to another, but better connect a wireless headset and listen to some music. In this case, you should check the stability of the connection. The range of Bluetooth is about 15 meters, so it will not be superfluous to move away from the headphones from the phone and check if the connection is lost.

Battery check

If the device battery is removedthen when opening the box should be placed separately in the package. A special protective label is glued to the contacts, which must be removed before installing the battery.

Important! The removable battery has a white indicator. If it is red, then moisture gets into the battery. Obviously, the battery should not be swollen or otherwise deformed.

Modern smartphones for the most part equipped with a non-removable batterytherefore it is impossible to look at it. In this case, you can check the smartphone battery in several ways.

1. We put the device on charging. We are waiting for 10-15 minutes and see if the battery capacity has changed. Here, in addition to the battery itself, the power connector is checked. Capacity should increase, even slightly.
2. On the device you can run video or call somewhere without dropping the call for 5-10 minutes. If the battery does not dramatically sit down, then it is fine.
3. In the phone settings there Item "Battery Information", There is prescribed information about the battery. His condition, how much he already works and other useful information.
4. there is special software on Google Playwhich gives information about the battery, for example, Nova Battery Tester or BatteryCare.

When buying a device you should not be afraid that the battery is already charged or, conversely, discharged to zero - this is normal. Sometimes when buying a device, it may not charge for some time, but only after some time, a percentage of charging appears. This is also not scary, because if the battery has been completely discharged for a long time, then it takes time to gain at least the minimum capacity.

Special software for testing smartphones

In app stores there are special programs that can drive the entire device according to different parameters. If the seller has nothing against their installation, then download Test Your Phone, Phone Doctor Plus and similar software. And then run them on your smartphone. In this software, there is usually a check of all items - sound, camera, sensor, smartphone, battery. This can be used, but not always the seller will allow to do this before payment.

Another option is use the utility of the manufacturer. They open after the introduction of a special service code. It is individual for each manufacturer, so you need to look for it in advance, and it is advisable to check it on another brand device.Suddenly the information on the Internet was incorrect, and the code itself was not working, and the buyer would decide that this phone was not original. Similar utilities work by analogy with third-party.
