1. If there is no signal or the signal is relatively poor in your location, it may be due to other objective conditions. Because the signal will be affected by various factors such as topography, landform, and tall buildings during propagation, if you are in a relatively closed place, the signal will be affected. Here's how to deal with it:

Turn the phone back on and off and try again;

Swap the SIM card to a family member's or friend's phone and try again;

Check whether the signals of other Unicom users around you are normal.

2. If it still cannot be used normally after self-service troubleshooting, it is recommended that you contact the local manual customer service for verification and processing.

There is no signal, and it is no problem to change to another mobile phone and try the card.

Professional mobile phone repairer replied that the chip is broken If it is licensed for less than a year, it can be repaired The chip is broken In my house, the mobile phone store has not replaced it I can only change the motherboard, which is about 2/3 of the mobile phone** Most likely it is an antenna problem.

Hello, my mobile phone repairman, the mobile phone signal is unstable, specifically to check, you first compare it with other mobile phones, in the same place other mobile phones are good, your mobile phone is not good if it is not a matter of the network, there are many problems with the mobile phone motherboard will cause signal instability, software problems will also cause signal diving, the upgrade team thank you for adopting I hope to solve your problem, if you are satisfied, please select "adopt" on my answer, a gesture will encourage us to continue to solve the problems of more QQ netizens, thank you. If the reply is inaccurate, you can add a question so that we can better answer your question, thank you.

Regardless of whether the warranty period has passed, it is recommended to take the machine to customer service for maintenance, it will not be too expensive, I have encountered it before, but mine is within the warranty period, but I didn't tell him that he was in the water (who is so honest), hehe.

1.Water ingress into the mobile phone is a very serious problem, and the signal is not good after the water ingress, indicating that the relevant components of the mobile phone signal are short-circuited and burned by water.

2.In this case, it is generally impossible to repair, and can only be restored by replacing the motherboard, but this method is more costly, and it is recommended to weigh whether there is a need for repair.

3.After the mobile phone gets into the water, it should be turned off immediately or the battery should be deducted, and then it should be thoroughly dried in a dry and ventilated place before trying to turn it on.

The circuit board is damaged and there is a short circuit, resulting in a bad signal.

Blow it with a hair dryer. And be careful in the future, generally the mobile phone will malfunction after water in the future.

If the signal is poor, you can directly weld a longer copper wire on the foot of the antenna switch of the power amp, and turn on the machine to see if the signal is better? If it's still the same, it's only a power amplifier!

It may be that the signal rod is damaged, and it is recommended to consult customer service for repair.

It must be that there are some places that can't be functioned due to water ingress.

I need to fix it.

Otherwise, it's very troublesome to keep doing this.

If your mobile phone is flooded with water or liquid, it is recommended that you do not try to turn it on to prevent damage to the internal components due to a short circuit inside the machine (if the machine battery is removable, it is recommended to remove the battery). It is recommended that you bring the machine to the local Samsung after-sales service center, and the engineer will help you test, and the specific cost is subject to the test results of the service center.

It may be that there is a problem with the power amplifier, and the general ** can be replaced with the power amplifier.

The general ** would just replace the power amplifier!!
