Matters needing attention in purchasing contract machines:
1, you need to pay attention to the place to buy, and try to go to some regular big places to buy. Generally, when we buy a mobile phone, we should be able to provide a formal purchase invoice. If we can't provide it, please buy it carefully.
If you want to buy a mobile phone, please explain the purchase in advance. Then, after buying a mobile phone, you should open the settings of the mobile phone and turn it on to see if it is the model you want to buy.
When buying a mobile phone, pay attention to the CPU of the mobile phone, which is the brain of the whole mobile phone. If you don't understand it when you buy it, first understand that you are not in a hurry to buy it, and then come back to understand the performance of the CPU through the network or other means. They are all CPUs of a certain brand, some high and some low.
