I believe that any Android mobile phone user has broken the screen once or multiple times. Once the screen is damaged, you can only change the screen assembly in the early stage. Later, with the improvement of mobile phone maintenance technology, it only costs 200 yuan to change the external screen separately.

The purchase price of an external screen is about 50 yuan, and it costs at least 200 yuan to replace the external screen. Changing the external screen seems simple, but it actually tests the maintenance master's skills. What the master earns is manual money. Generally speaking, better quality external screens will have more sensitive touch, but they are almost impossible to be the same as original screens, especially for models with original screen touch sampling rates above 360Hz.

In addition to changing the external screen for 200 yuan, you can also choose to changing the assembly for 600 yuan, but usually this assembly does not necessarily have the original inner screen, but may be a third-party inner screen. This is suitable for models where the inner screen has also broken. Generally, users with good inner screen do not recommend changing the assembly.

For users, whether to spend 200 yuan to replace the external screen or 600 yuan to replace the assembly depends on the degree of damage to the mobile phone screen. But there is one situation that everyone should pay attention to, that is, the inner screen is obviously not cracked, and the merchant also advises you to change the assembly, which is a bit of a "slaughter".
