4. The Bluetooth of the mobile phone and the computer shows that they have been paired, and the computer shows that the mobile phone is connected, but the mobile phone cannot connect to the computer. What is the situation?

It’s probably like this. The Bluetooth of the mobile phone cannot be connected to the computer. It means that it is paired but cannot be connected all the time (as mentioned in the title). It is probably because the computer level is higher than that of the mobile phone, but the mobile phone cannot be used as a pair of headphones. pieces.

However, file transfer will not be affected (currently I have only used file transfer, and there are probably no other functions). If you want to transfer from the mobile phone to the computer, you must first turn on Bluetooth on the computer, choose to receive files, and then send the files from the mobile phone to the computer via Bluetooth. On the contrary, if you want to send it to the mobile phone, you only need to send it from the mobile phone first, and then choose to accept it from the mobile phone. For large files, it is faster to use a data cable or QQ, but Bluetooth is slower and prone to errors and interruptions. (The question is a question I asked a few months ago. It seems that no one has really solved it yet. This is a question and answer for myself...)

5. The mobile phone cannot connect to the computer via Bluetooth. The mobile phone shows that the connection failed, but the computer shows that it has been connected. What should I do if I get a mobile phone?

Can you just turn off your computer’s Bluetooth?

6. Why can’t the Apple phone connect to the computer?

Why can’t the Apple phone connect to the computer?

The Apple phone is one of the most popular smartphones on the market. However, Sometimes we may encounter a common problem: unable to connect the Apple phone to the computer. This issue may cause a lot of trouble for users, unable to transfer files, backup data, or perform other operations. So, why do Apple phones have problems connecting to computers? Next, we'll explore a few possible causes and solutions.

1. The USB cable is loose or damaged

First of all, a common reason why the Apple phone cannot be connected to the computer is that the USB cable is loose or damaged. Due to long-term use or frequent plugging and unplugging, the USB cable may become worn, deformed, or damaged, causing connection problems. To resolve this issue, you can try using a different USB cable and make sure it is connected tightly. In addition, it is also important to check the status of the USB cable regularly.

7. Why can’t the mobile phone and the computer be connected?

Why can’t the mobile phone and the computer be connected?

With the continuous development of technology, mobile phones and computers have become an indispensable part of our lives. But sometimes we find that the mobile phone and computer cannot be connected, which may cause us a lot of trouble. So, why can’t the phone and computer connect?

Network Problem

First of all, we need to check whether the network connection is normal. Sometimes, due to unstable network or incorrect network settings, the mobile phone and computer may not be able to connect properly. At this time, we can try to restart the network device, check whether the network settings are correct, and try to reconnect.

Driver issues

Secondly, we need to check whether the device’s driver is installed correctly. The driver is the interface software between the computer and the hardware. If the driver is not installed correctly, the device may not work properly. At this time, we can try to reinstall the driver, or use the driver update tool to update the driver.

Safety Issues

In addition, we need to consider security issues. Sometimes, your phone and computer may not be able to connect properly due to incorrect security settings or malware attacks. At this time, we need to check whether the security settings are correct and update the operating system and applications regularly to prevent malware attacks.

8. When the mobile phone is connected to the computer, it shows that the USB cannot be connected?

Meizu mobile phones use the latest MTP protocol (a new technology for USB interface). The use of this new technology makes the phone copy files much faster than previous products. I tested it. It only takes 60-75 seconds to copy a file of about 1.0G.

However, this new protocol requires you to update the driver under the XP computer operating system, so that you can enjoy the pleasure of copying files at high speed.

The specific method is as follows (taking MX3 as an example):

1. Software requirements ensure that the firmware version of your MX3 is (A9865) or above, and windows media player11 is installed in the XP system of the computer (if not, download it online What should I do if I don’t know how to download and install it in the future? ? I’m not a kindergarten teacher and I won’t teach you this step);

2. Connect the MX3 to the USB port of your computer (preferably the rear one) ;

3. Open the system on MX3--About phone--Storage--USB computer connection, then turn on USB connection notification and media device (MTP). Do not turn on USB debugging (many Mei friends make this mistake)

4. Open My Computer (right-click) on the computer, properties - Hardware - Device Manager

5. Find the M353 device in the list and choose to update the driver. The computer will prompt you to automatically search for updates. Just follow the computer prompts and proceed to the next step. Wait until the computer prompts that the MTP device is successfully installed. (After many verifications, it is found that many Mei friends cannot find MX353, or MX351, MX040 at this step. The reason is that the XP system is a simplified one-click restore version, and some functions are incomplete, so they cannot continue to the next step. I cannot solve this, please Reinstall the full version of XP or WIN7 or above operating system)

6. In this way, you will find in the system display that the computer recognizes that your phone is MX3.

7. At this time, when you connect your phone to the computer, a prompt box will pop up asking you how to open the device. Some of them are folder methods. If you choose to open, you will see a display of a memory device. Just open it. Copy files like a USB flash drive. (You can also see the MX3 icon when you open it in my computer)

That’s it for now. If you have any questions and you don’t understand, you can ask me again. The contact information is to reply to this post or text me on the site.

PS: If you use the U disk function in an Internet cafe, you can only turn on USB binding, and then use 360 or Wandoujia to connect the phone. The computer will automatically install the driver, and then transfer files through 360 or Wandoujia.

MTP protocol does not require ejecting the USB flash drive, just unplug the phone after use. I've been using it this way without any problems.

Repost:

Tips on using the disk function normally under the It has become an integral part of our daily life. And when we want to use the computer to perform some operations on the mobile phone, we find that the computer can only charge the mobile phone and cannot perform other operations, which can't help but make people feel confused.
