The screen of the mobile phone is broken, and changing the screen has an impact on the mobile phone.

1, the touch sensitivity is not as good as before.

If the touch sensitivity is not as good as before, it is likely that the quality of the replaced parts is not enough and not all of them are original.

2. There is something wrong with the cell phone signal.

Generally, the signal detection in the later stage of maintenance is to dial the alarm number for an empty card. If it can be typed, it means that the signal is ok. In extreme cases, there will be no signal after inserting the card. If this happens, it may be that the signal antenna is improperly installed during maintenance, and the signal part of the motherboard is artificially damaged, resulting in poor contact of the chassis antenna during maintenance.

3. The screen and the border are not firmly bonded.

Mobile phone screens are particularly afraid of liquids, so when the screen and the frame are glued together, a professional glass glue is usually used around the screen. The characteristic of this glue is that the longer it is used, the stronger its viscosity will be. It is not very sticky when it is first dipped, and it takes a long time to keep warm and maintain pressure. And informal repair shops often save trouble or the quality of glue is not enough, which leads to the screen degumming of consumers' mobile phones just after they are repaired.

There are small bubbles on the screen.

This situation will occur in a few cases when the external screen is changed, which may be the problem of pressing the integrated screen, or it may be related to the machine performance. Of course, obvious bubbles must be repaired immediately.

To be sure, changing the screen will not affect the operation of the system, and there will be no problems such as machine jamming and slow operation after changing the screen.

Extended data:

To measure the display accuracy of a screen, the resolution can only be regarded as one aspect, because we have to consider the screen size. We use ppi to represent pixels per inch, and ppi value indicates how many pixels are contained per inch. The 4.7-inch iPhone has 326ppi pixels per inch, which is also the retina screen defined by Apple. It means that at a certain viewing distance, the human eye cannot distinguish the pixels on the screen. Although this figure is not accurate, it is enough for users who are not demanding. The 5.5-inch 1080p screen pixel is 40 1ppi per inch, which is clear enough for non-critical users.

So is it necessary to have a 5.5-inch screen resolution of 2K or higher? In fact, there is not much difference between the accuracy of human eye resolution 1080p and 2K at a viewing distance of 20cm. Simply give a small screen size of 1080p or 2K, it's hard to say what the resolution is. Moreover, high resolution means high power consumption and high processor load, which is why many manufacturers are reluctant to go to the 2K screen. After all, it is a test of endurance and heat control.

The screen resolution of mobile phone is not as high as possible, and the choice of mobile phone depends on the demand. For ordinary users, the accuracy of 1080p is enough, and it saves electricity and CPU load.
