There is an old iPad on hand, which should be the fifth generation of 17 models. Most of the time, it is used in office. I touched the upper right corner of the screen when I first got there. The iPad itself is fine because it is a metal edge model, but the screen has three cracks. Although the screen is cracked, I can scratch the cracks with my finger without any scratch, and it does not affect the use of the touch screen, so I did not want to replace it.
One thing to say, the quality of the iPad is really good. I shut down the positioning, notification, and background refresh. After several years of use, the battery is still powerful. But recently, I don't know what's going on with the touch screen. It started to be out of control and even clicked randomly. At this time, I had to lock the screen immediately, press the screen and unlock it again, so that the touch screen could return to normal. Could it be that with the passage of time, moist air passed through the outer screen and entered the internal touch screen, causing a "short circuit"?
To save money, lock the screen every time the touch screen is out of control, press the screen and unlock it again, which is also useful. But inevitably, when there are many people, the screen suddenly starts to click randomly, which is embarrassing. In addition, small pieces of glass slag began to fall from the touched place in the upper right corner of the screen, and it was no longer safe to scratch. Therefore, screen change was put on the agenda.
At the beginning, I went to a store, which only sold products and did not provide maintenance. Fortunately, the clerk could contact me and asked about the parts, so I went straight to the store. After arriving at the store, the maintenance guy took the iPad and played with it. Then he called someone to send the outer screen to him. At the same time, he turned off the machine, heated the edge of the screen with a hair dryer, and peeled off the screen with a dial. Less than an hour later, the iPad has regained its youth.
The external screen costs 480 yuan, which is acceptable.
