Everyone's mobile phone use habits are different in everyday life. Some people cherish it very much, while others are just a telephone tool. Next, let's take a look at some common examples and how to deal with them after they meet.

1. I believe that most people have encountered the water, many people come out of the water and want to start the phone properly, and then press the POWER key and HOME key desperately. In fact, this is a wrong or even fatal practice. When the mobile phone is in the state of startup, the good luck may only be the short circuit of the positive pole line. This kind of fault is that the mobile phone does not turn on, the damage is small and the maintenance difficulty is low. The bad luck will cause the short circuit of other lines, and then the mobile phone will be very hot until the battery is exhausted. In this case, it needs to shut down immediately (when the battery is exhausted). However, if the screen touch is available, the longer the boot time, the more serious the damage, or even unable to repair.

To sum up, press the HOME button in advance of the water intake machine. If the screen is not bright, it is basically shut down, so there is no more operation. If the screen is lit, shut down immediately and send it to repair as soon as possible. In this way, the damage degree of part of the influent can be reduced to a greater extent.

.The degree of damage caused by external force impact on mobile phones can not be underestimated. The lighter one is virtual chip welding. Serious one will lead to layer breakage and can not be repaired. So if your cell phone often falls down, it's better to bring a soft cover or something to protect it from unnecessary damage.

3. There are some types of faults in the maintenance order: in normal use, there is no signal suddenly, reboot is useless, and then according to the online tutorials to brush the machine, the result is wrong, boot is the interface of data line mode, and can not enter the main interface any more.

This failure is caused by failure of the baseband part to run properly. The big problem with this operation is that once you brush the machine, it will be very difficult to repair, because the fault point is in the baseband part, and the starting baseband of the machine after the brush error is not started, so all the voltage can not be measured. It takes time to measure the edge of the brush.

So how can we avoid this problem? When you have a signal-related malfunction on your mobile phone, first look at the settings - Generic - about the local machine, see if the modem firmware in it is behind the version number, if it is blank, do not brush the machine. Send it to repair on time.

4. Suddenly there is no reaction from the black screen in normal use. At this time, you can hold down the POWER and HOME buttons for 10 seconds at the same time. If you don't turn on the computer, try to connect to the computer, open iTunes, and start the DFU mode brush without information display. If you don't turn on the machine, you can only repair it.

5. The time of the iPhone will be back to 1970 when it is completely powered off. When you charge and turn on, you need to connect Wi-Fi to automatically adjust the time to the current Beijing time. Otherwise, you can't insert SIM card and turn on the camera without using the flash status option.
