What happened to the recent disconnection of Apple's 4s mobile phone?

What happened to the recent disconnection of Apple's 4s mobile phone? One is the signal problem, or the antenna of your mobile phone is damaged, or it may be that you upgrade too fast, just brush it off.

There are two reasons why Apple 6 always gets disconnected on the phone. On the one hand, the signal is not good, on the other hand, the baseband problem of the mobile phone itself.

1. In the scenario of dialing 10086 or other operators (excluding the bad signal of the other party) and disconnecting. See if your cell phone signal is a grid or-100 db. If so, the signal is not good (especially high level). We can't use mobile phone 4G to surf the Internet to judge the signal strength. At present, 4G services are mainly data services, not voice services, and voice services are 2G.

2. If both parties can confirm that there will be a high drop rate when the signal is good, please call the operator (China Mobile Unicom) to confirm that there is no base station to maintain your position, because the uplink signal is not good and the downlink signal is good, and there will be a signal but you can't talk.

3. If all the problems are eliminated, please contact Apple's official genius and ask the engineer to run the hardware analysis remotely to eliminate the problem of determining the baseband module of the mobile phone (services include the US version of the mobile phone, the Hong Kong version and any version of the Bank of China). If it is determined that it is a hardware problem, it can only be repaired.

IPhone 5S has been disconnected recently. What happened? 1. First of all, Apple 5s uses small cards, and some people's cards have been cut, which may cause problems.

Secondly, it may be the signal problem of the telephone company.

3. It may be that the signal in the area is not good, such as subway, hospital, mountain area and so on.

4. Maybe the other party hung up.

What's the matter that Apple 5 always can't get through on the phone? 1. First, connect the mobile phone to the computer with a data cable, and follow the prompts to install iTunes on the computer.

2. Download and install a 9 1 assistant. Connect the data cable to the mobile phone and use your brain. Open the upper left corner of 9 1 assistant and select' Enter Recovery Mode' to restart the phone naturally. After restarting the phone, itunes will connect.

3. Open itunes on the computer, and it will appear after the connection: Restore, select Restore, and the recovery time is about 40 minutes.

About the maintenance of OPPO mobile phone:

1. Avoid exposing the mobile phone to the hot sun or rain, and avoid bumping. If the phone is soaked in water or rain, please dry the shell as soon as possible. If the water is seriously flooded, do not start the machine immediately, so as to avoid internal parts being burnt by conduction. Please send it for repair as soon as possible.

2. If you don't use your mobile phone for a long time, you need special moistureproof treatment. In southern areas such as South China, the weather is rainy and humid, and the moisture inside the mobile phone will cause damage to the parts.

3. Using your mobile phone correctly will generate a certain temperature inside the mobile phone, which will evaporate the water vapor accumulated at ordinary times.

4. Avoid touching the antenna.

5. To avoid damaging your mobile phone and affecting its call quality, please don't install unqualified antennas or modified parts.

6. Keep the phone dry. Rain, moisture and liquid contain minerals, which will corrode electronic circuit boards.

The mobile card for iphone4 will be disconnected in the last few minutes. What happened? Try changing a mobile card.

What happened when Apple 4s called the other party and there was an echo in the iphone4s call? The other party heard him, but he had no influence at all.

Try to cover the small hole next to the earphone with your finger when you speak. That's a microphone, too. It's for hands-free use.

Or try to turn down the volume and ask the other person if the echo is small.

According to the test, it was found that the hole next to the earphone was the cause. It may be that the earphone is too loud and the sound is transmitted to the microphone, so the solution without disassembling the machine is to stick something there.

This is the simplest and most convenient solution. Some beautiful stickers look more beautiful.
