用磁铁在屏幕上吸一遍。使用USB数据线将手机与电脑连接，看看是否可以解决。

1、静电极容易击穿电容屏，虽然手机屏幕表面的玻璃都是经过一定的抗静电处理，但不代表能能承受人体的静电，有很多米粉朋友习惯在手机表面帖一些装饰品或者容易产生静电的劣质屏膜，导致屏幕发生失灵，所以希望有条件可以给手机配一个外壳或皮套等。

2、远离高温。这个大家都应该知道，手机很怕高温的，尤其是安卓类智能手机，当然，小米是高配置手机，为发烧而生，本身就有一定的热量了，所以要再加上其他的高温，那就是雪上加霜。遇到高温也会触屏失灵。

3、虽然电容屏一般是不需要测试的，但是也有例外情况，屏幕乱跳，暂时失灵，或许我们简单的校准测试下是有效果。在拨号界面输入“*#*#64663#*#*”进去后，选择触摸屏测试。

Do it on the screen with a magnet. Connect your phone to your computer using a USB cable and see if you can fix it.

1, static electrode easily breakdown capacitance screen, while screen on the surface of the glass is through certain antistatic processing, but do not represent can withstand the human body electrostatic, there are a lot of rice friends habits in mobile phone surface decorations or prone to electrostatic inferior screen film, cause a failure of the screen, so I hope conditional for match a shell or the mobile phone holster, etc.

2. Stay away from the heat. This we all should know that mobile phones are very afraid of high temperature, especially android smart phones, of course, Xiaomi is a high-configuration mobile phone, born for fever, itself has a certain amount of heat, so to add other high temperature, that is worse. The touchscreen also fails at high temperatures.

3. Although capacitive screens generally do not need to be tested, there are exceptions, such as screen jumping and temporary failure. Maybe our simple calibration test is effective. Enter "*#*#64663#*#*" in the dial interface and select touch screen test.
