Select tablet to pay attention to these

Tablets are becoming more and more popular. Although they are acceptable in terms of price, they always want to spend money on things to buy and value for money. In addition, outsiders do not want to be made a fortune. There is, the most troubling problem: renovation. Follow the following points to select a satisfied, non-refurbished tablet.

1, text part Many products are printed on the back of the fuselage including the product logo, including graphic text. This type of text is generally printed on it using special techniques and is therefore not integral with the backplane. After using the product, the surface of these pictures and graphics will appear different degrees of wear, the most typical is their own color darkening, or with other products of the same color of their own. Because in the renovation process, because the abrasive replacement is more troublesome, many black heart merchants have adopted the method of polishing. As a result, many worn LOGO surfaces will appear relatively unusually shiny and appear to be very uncoordinated.

2, the interface part of the interface part We usually mainly look at the application of more USB interface and headphone jack. The TF expansion interface and the HDMI interface do not care much because the application frequency is less.

First we have to look at the edge of the headset and the USB interface. The frequency of these two interfaces is very high, so the edge of the interface is easy to leave traces of wear. Especially the USB interface, because of the sharper interface corners, Fan new products will have obvious processing traces. Moreover, the internal metal parts of these two interfaces can also be observed with the eyes. Because of these refurbished products, these metal parts will be weakened due to wear and tear on the surface of the oxidation part, the slight discoloration is still very easy to observe.

3, most of the audio part of the Tablet PC has put the sound. Since most of the sound surfaces used are bee-like designs, the acoustic parts of these products are contaminated with dust, whether used or not, and are not easily cleaned. And we all know that many good sounders will have similar filamentous substances after listening. Some relatively high-end enthusiasts know that this is a special kind of material produced by certain headphones after the “Shu headphones”. The cleaning is also not easy, it will be attached to the sound surface.

4, shell screws Early tablet products in the design of the appearance and did not use screw-free design. Even today, due to cost considerations, many small brands still use this old-fashioned appearance grinder. With this kind of design, we can judge the new and old products by looking at the screw condition. Because the surface of the screw will use some anti-rust treatment. The rust-proof layer of the used product will be damaged in any way. In particular, some products with black shells, the screws are generally the same black treatment, even if not removed, there will be some traces remain.

5, shell edge In addition to some low-cost products, many products are now using a shell-less grinder with a screw-free design. This type of housing requires tools to move the joints during maintenance. Therefore, after the refurbished product may appear some obvious traces. In addition, many tablet computers use plastic materials even if they have not been disassembled and repaired. The current technology of this kind of shell is not very mature, so the used products will appear more or less "alice" situation. This is due to the hot nature of Android. In addition, I would like to remind everyone that some scratches will appear on the edge of the product, but it does not mean that the product is a refurbished product. Because the products are all mass-produced in the assembly line, some tools are used to place and fix the products in the batch placement process. And some scratches were formally created during the process of placing and fixing. Therefore, when comparing scars and scratches, we should be careful to use two identical machines for comparison. If more than two machines have the same scratches, it means that the scratches on this machine originate from production, and vice versa. Refurbished.

6, recessed screen Tablet PC screen is now divided into concave or overall coverage of the two. If it is a concave screen, then we have to carefully observe the position of the upper right corner of the product screen and the lower left corner of the product screen when selecting. Because these positions are the main corresponding positions of touch buttons on Android screens, if they are used products, then even if they are used with great care, how carefully the refurbishment, then there will be more or less on the product. Other edge positions are different.

7, cameras and mobile phones, digital cameras and other locations. Tablet PC HD cameras are also more prone to dust accumulation. The new machine's lens frame is very clean, no stains and scratches, and the surface can also see the obvious metallic luster. The retreader's lens frame has obvious signs of use, there are a layer of gray black stains at the four corners, but also can see the shape of the back cover lens hole.

8, the screen often press parts of some tablets, especially soft-screen tablet. During the refurbishment process, although the workers cleaned up some traces of retreading, some traces could still be identified by trial. For example, where the screen is often touched. We can find it by watching it from multiple angles. For example, if there is a frequently pressed point in the middle of the screen, then perhaps we will not be able to tell from the front, but if we put the tablet sideways and reach an angle of 30 degrees or more under the light, then this point will There are significant differences in the other locations on the product screen.

Above, we shared with you several major easy-to-find matters. All these precautions are based on the appearance, and they are all visible to both eyes. These methods are not too esoteric, but they are just some of the details discovered by people who have used the product. It is precisely because of this that these methods are more suitable for our ordinary consumers. I hope that everyone can watch the above items and apply them to the purchase of products to help consumers purchase genuine new products. They are not fooled by poor refurbished machines and unscrupulous merchants.
