This method can basically determine whether the standard of a brand-new machine is accurate. Find more machines and try it! How do I know what it smells like? Is there any other way? And I’m a MM, so it’s weird to smell the machine like this! Okay, okay, let’s continue with other ways to check whether the machine is brand new. First, pick up the machine and look carefully at the appearance. It’s best to look at a place with a light source to see if the outer shell is shiny or not. It’s a normal brand new machine. There are no scratches! Of course, the original design is another matter. Secondly, you should carefully observe the screws of the mobile phone to see if there are any traces of being tightened. The color of the screws will be very uniform. If you are afraid that JS will fill in the color with ink, (it is possible) then bring a cotton swab to wipe it. After that, carefully observe every gap of the phone to see if there is any dust or dirt inside, because a brand-new machine will not have dust in the corners. No matter how careful you are in refurbishing a new one, there will be some blind spots that you can't deal with. Another thing to pay attention to is the degree of wear of the metal contacts of the SIM card slot and the battery compartment. They should not be very bright, but should be muted and have no traces of use. If it is a mobile phone with a touch screen and a stylus, take out the stylus of the phone and look at the pen tip and the pen groove to see if there is any dirt or wear. Then there should be an original protective sticker on the screen of the mobile phone. It is oily, not sticky, so it is easier to tear off. If you see a mobile phone with a protective sticker bought from outside, there is usually something wrong with it. ! The appearance of the mobile phone has been checked and there is no problem. The next step is to turn it on and check it. The first thing you do when you turn on your phone is to open an all-white, red, green, blue, and black picture to see if there are any dead pixels or bright spots on the screen. Finally, save the picture to your phone in advance. Use Bluetooth or infrared to transmit it, and try the Bluetooth functions by the way. After the screen are the buttons of the machine. Press them all. Usually the new ones are very crisp and not greasy. They feel very good. Then try putting it on your phone. And taking photos. What needs to be noted is that you should look at the file name saved when taking the first picture. Usually it should be XXX-001.jpg on a new machine. Of course, it’s best to do this later. Then try making a phone call, both parties must be talking! Instead of just making free voice calls, call a friend or your mobile provider's customer service. For example, 10086, haha! ! If there are no problems, congratulations, you are very close to buying a new mobile phone! ! All that's left is to try to see if the accessories are normal, and check whether they are original and used. Not much to say here. Today I will share with you so much experience in buying a machine. I hope it will be helpful to you!
