Generally, the screen replaced by an Android machine is very poor. Once it is broken, it is also better. The skill of distinguishing is to pay attention to the smoothness of 2.5D radian of the screen edge and the amount of oil drainage layer.

The good screen is smooth and smooth, The oil layer is thick, but the price will not exceed 300 yuan. If a profiteer asks you to ask for RMB 4500, you can leave immediately.

Nowadays, many mobile phones are OLED screens, which cost a lot of money. Of course, the price of changing the screen is also high. However, there are a lot of very vicious profiteers who do not want to replace the original screen for you, but also replace it with one LCD this cheap material screen, because this can be said to be profiteering, a screen can even earn 500 or 600 yuan, outside is not visible, if we encounter this, we can take a magnifying glass to identify.


Adjust the screen to a white screen with no text or pattern as far as possible, and observe the pixel arrangement of the screen with a magnifying glass. Like the iPhone X and above series, many domestic flagship are Samsung’s diamond pentale sub-pixel arrangement, like the one above.

The Replacement LCD is quite different. Most of them are arranged in rectangular standard RGB arrangement. As shown in the above figure, if you find that your mobile phone is originally an OLED screen and replaced by an LCD by a profiteer, you can use this method to immediately go to him to lose money.


Another method is to identify whether the external screen of this assembly is original, just like the method above. In addition, the screen can not be significantly higher than the border after changing the screen. Generally, the screen assembly that is not the original one will be thicker than the original one. So there will be prominence.
