How to check XT70 1 motorcycle?

Hello, the landlord, what I gave you is the general method of checking the machine, which I think will also help your mobile phone:

1. First of all, the new machine smells of sandalwood as soon as it is opened. When renovating, the taste will be different due to material problems, and the data cable interface will be worn, oxidized and dusty. If it is a slide phone, check whether the slide is loose. At the same time, the shell of the refurbished machine is not original and meticulous, the gap is uneven and burr, and the shell feels poor.

2. Disassemble the back cover of the mobile phone and check whether the screws are worn, but note that the European version of the mobile phone needs to be disassembled to replace the stroke keyboard. Whether the Sim card is worn out by electric shock, but since parallel imports are generally boot tests, the problem is not great only if the wear is not obvious.

3. Boot test, we mainly test whether the signal is stable and there is noise during the call; When writing short messages, are the keys sensitive and how do you feel? Block the camera with your hand to see if there are bright spots in the all-black picture and whether the picture can be stored in the expansion card normally.

4. There are many ways to check by looking at various software parameters of mobile phones. Because the serial number, code, MAC address and other data of mobile phones can be modified by software now, it is of little practical significance.

At present, the competition in the parallel mobile phone market is very fierce, and the profit of the mobile phone itself is already very small, but many businesses still focus on accessories. For a very simple example, an original Nokia mobile phone battery costs at least 100 yuan, and a high imitation knockoff product only needs 20 yuan. If you count accessories such as headphones, the profit of accessories is even higher than the mobile phone itself, so you must check the accessories in detail after checking the mobile phone.

6. The last point is the warranty. Now merchants will provide a certain degree of warranty service, such as one-week replacement and one-year warranty. Everyone should carefully look at the specific warranty terms, which issues are guaranteed and which are not guaranteed. Maintenance points are generally separated from sales points. It is best to consult in detail and keep the receipt or other proof of purchase.

Thank you for your adoption.
