Make sure your device is rooted first. If you want to update the rooted device, you can update it after flashing the original version. If you have an unrooted device, you can try to unplug the memory card and reboot it.

As we all know, the screen of a mobile phone is divided into two parts, one is the touch outside; The other is the inner screen. After we accidentally drop the phone, the first thing we need to do when we pick it up is to see if the screen of the phone is broken. See if the outer screen is broken, or if the screen is not displayed at all.

Usually, if we find that the outer screen of the mobile phone falls on one or two small lines, we generally will not repair it, because it does not affect the use, and we are too lazy to repair it. Unless the phone is dropped and does not display, we will repair and replace the screen.

In fact, the outer screen of the mobile phone is the touch screen, which is not very expensive. The purchase of their mobile phone store is about 20-30 yuan, and the rest of the money is their manual fee. Of course, people rely on this kind of technology to eat, and it is understandable to charge you a little manual fee.

However, if you ask for a price in bad faith, it will be excessive. This friend who repairs mobile phones has been in this business for many years, and because of his excellent technology, he is most affordable. It has won the recognition of many old customers.

He said that I usually change the outer screen of a mobile phone, ** is generally about 70-80 yuan, and the cost is removed, that is, the manual cost of transferring 40 yuan. Of course, there are also mobile phones that are more difficult to disassemble, such as vivo X6, which is difficult to disassemble and risky, ** are also around 120 yuan. I said what to do if it is broken, and he said that before the repair, he will report the risk to the customer, so that the problem will be solved.

The outer screen is like this, the maintenance is complicated, it is not as simple as changing the assembly, and it makes more money.

What is a change assembly?That is, when our mobile phone is dropped to the screen and does not display, it can be replaced. Because, the inner screen of the mobile phone is the core of the whole screen, once he is dropped or flooded, it is impossible to repair it, only to replace it.

The ** of the assembly is much more expensive than the outer screen, after all, it is the main course. The screen assembly is divided into the original screen and the assembled screen;The original screen** is very expensive, and some even exceed the current mobile phone**. This kind of reference to the customer service maintenance point can be seen.

There is also an assembly screen, which is a mobile phone screen manufactured by some peripheral small manufacturers through a certain method. This kind of screen is cheap and profitable. Although it is not as popular as the original screen, it also has a certain market.

These two kinds of screens, unless the maintenance personnel tell you whether it is the original screen, you will know. If they don't say it, treat them all as original parts. Ordinary people generally can't see anything boring.

As a result, many black-hearted merchants use assembled screens for customers under the banner of the original factory. What's more, they charge you the ** of the assembly when they change the external screen for profit, and this situation is no longer rare.
