Solutions to common problems of mobile phones

Details are as follows:

First, the phone automatically shuts down when answering or making a call.

Everything is normal when the mobile phone is on standby, but it will automatically turn off as long as you answer the phone or make a phone call. In addition to software reasons, most of them are due to the problem of power amplifier IC. Because when transmitting and receiving signals, the power of the mobile phone is relatively large. This problem will occur if the performance of the power amplifier IC is poor.

Second, the direct charging of the mobile phone cannot be directly charged.

It is mainly the fault of the charging circuit of the mobile phone, and it is generally enough to replace small components. You can also take a direct short circuit to remove this function and charge it with a seat punch.

3. The prompt "Please insert the SIM card" will appear on the mobile phone.

This prompt is generally caused by poor contact between the mobile phone contact and the SIM card, and can be operated in the following ways.

1. Take out the battery and SIM card, carefully pry the contact up a little with tweezers, and then carefully wipe the SIM card with a rubber, which is generally ok.

2. If the above methods are not effective, it means that there may be a problem with the connecting wire between the SIM card holder and the processor, and it is best to send it for repair.

Finally, the possibility that the processor chip is broken is not ruled out.
