What to do if the computer does not see the device connected via Bluetooth
Faced with visibility problems when connected via Bluetooth, try the following measures. Follow these steps in turn, and perhaps one of them will help you.
1. Make sure that both devices have Bluetooth turned on, and in the settings on each of them the visibility mode is activated for all other devices. On iOS, these settings are included in the AirDrop service, available at the Control Point.
2. Place the tablet or smartphone closer to the computer.
3. Restart the computer and mobile device.
4. If before the devices were successfully connected to each other, delete the saved pair in the Bluetooth settings and try reconnecting.

Alternative Connection Methods
You always have a backup option - services with which you can transfer files between your computer and mobile device via the Internet. This AirDroid, Pushbullet, as well as cloud storage such as Google Drive, OneDrive and Dropbox. They will allow you to do without Bluetooth and USB, if these options do not work or do not fit.
Why does a laptop or computer working on XP, windows 7, windows 8, windows 10 not see usa xiaomi redmi phone, samsung galaxy, lg, htc, huawei, lenovo, meizu, sony xperia, asus, nokia, bq, fly, honor, honor, alcatel one touch, mtp, dexp or mts with android 7.0, android 6.0, android 5.0, android 4.4 2 and so on.
In fact, there are various ways to connect a mobile device with a computer to share files remotely, for example, through the clouds, we can also connect via Wi-Fi, bluetooth, the corresponding application, or do it the classic way with a USB cable.
Only in spite of simplicity, the latter method (through us) is sometimes the most problematic. When you connect a computer or laptop, or rather the Windows system, you need to find the appropriate drivers.
If they are not found, then the connected usb phone on usb will not be visible to them, but this is not the only reason. There may also be another error that prevents the connection. Let's look at the main reasons why this happens.
NOTE: the pictures are made on Samsung Galaxy A3 with android 7.0, but on others like a5, s3, a3, s4, j1, s5, xiaomi redmi 4x, 3, mi5, 4a, and all the other differences are not big.
If your computer does not see photos, files, folders, music after flash, the microsd flash drive is not visible or does not recognize it as a device, as a drive, as a modem, then the problem may be in unsuccessful firmware, but most likely you did not turn on the required protocol (how to enable about him below).
The main reasons why a computer or laptop does not see an Android phone connected via usb and what to do
Samsung Galaxy Phone, Lenovo, Nokia Lumiya, Asus Zenfon, Meize, Sony, Xiaomi, Huavey, Alcatel, Xiomi, Fly, Honor, Micromax, Sony Ixperia, Philips, Prestige, like any other equipped with a USB port can not be recognized if The device has been exposed to water. Make sure the USB port is completely dry before plugging in the USB cable.
For a smartphone or tablet to be visible to a computer or laptop, the device screen must be unlocked, and the USB connection is turned on for transferring files. Connection mode is always set to charging only by default.
So that the computer can detect the cell phone, choose the connection mode for transferring files every time you connect the device to the PC.
Also make sure that you use the original USB cable specifically designed for this device, and it is properly connected to the computer.
If Windows does not see the phone anymore, try using a different USB port on your computer, just do not use a hub or USB extension cable. Try using a different cable to make sure the one you are using is not damaged.
If the phone has a micro SD card, turn it off, remove the USB flash drive and reinsert it. Reboot the computer. Turn on your smartphone or tablet and connect it to your computer using a USB cable.
Problem still exists? Try using another computer or look for the USB driver for the device you are using; see in Device Manager if there is a yellow sign.
If you are using Windows N or KN, download the Media Feature Pack to allow file transfer. These versions of Windows do not support file transfer using MTP. For XP, you need to install the MTP (Media Transfer Protocol) protocol from the Microsoft website.
Five brief reasons why a computer / laptop does not see a smartphone / tablet when connected via a cord

What to do to properly connect your smartphone via USB so that it is visible to a computer or laptop
Photos, videos, installing multiple applications or downloading music from the Internet - all these activities effectively exhaust the memory of your mobile phone.
In order to increase the capabilities of your smartphone, you must periodically transfer the most important data to the hard disk of your computer.
Archiving files, contribute to improving the security of files (as backup) and allow virtually no limit the memory of the smartphone.
Below you will find three simple steps on how to connect your phone to a personal computer.
Step 1 What to do - connect a smartphone or tablet
When you connect a smartphone or tablet to your computer with a usb cable, Windows will automatically detect the new hardware and install the most necessary drivers.
Only with older versions of software from Microsoft, for example, Windows XP, problems may arise. You will need to update windows to the latest version or download MTP protocol.
Step 2 what to do - setting up your phone
When connecting, you need to choose the right communication protocol - this is the key to access different types of files and programs. Below I will explain two options:
Media Device (MTP) allows you to access all multimedia files, such as photos, videos, or music. MTP allows you to download and delete all the contents of your mobile phone.
Camera (PTP) - this option recognizes the phone as a camera and allows you to directly overwrite files in specialized programs that process graphics in the form of RAW. If you connect correctly, the phone will require permission - allow.
NOTE: Do NOT delete important Android system files located in folders labeled “Android”.
Step 3 What to do - transfer files from phone to computer
To view your device, launch My Computer. Among the discs, you should see your phone, and file transfer is very simple - you can simply drag and drop files or copy and paste.
Usually the computer asks what you want to do. You can choose one of the options, but not necessarily.
NOTE: in older versions of android, there are more modes of connecting via USB - the optimal USB Mass Storage in use. You can switch to it by clicking on the connection message in the notification area.
Why the phone does not connect via USB to the computer - it only charges
The first thing you need to do is set the settings correctly in the “Developer Parameters” How to get there -.
If the phone is only charging, then try to connect to another USB port. If you have 3.0 and 2.0, then try 2.0 first.
If you find other similar USB cables in the house from other devices at home, try connecting with them.
Connect to another computer. If they also do not see the phone, then the problem is in the phone or cable. If he sees - the problem is on your computer. Open Device Manager and turn off power saving for Generic USB Hub.
IMPORTANT: the new android versions are configured by default so that when connected via USB to a computer, the phone will only charge. You need to change the USB mode from USB charging to another.
In conclusion, I repeat. If it is very important for you to transfer files to your computer, but he doesn’t see the phone by yusb, you can use other methods: synchronization via Google Drive, OneDrive, Dropbox, Yandex Disk, AirDroid application, and also transfer them via wifi or bluetooth.
This concludes, but remember - I am always happy to quickly answer your questions in the comments below. Successes.
The modern level of development of smartphones, personal computers and tablets is amazing. However, a set of various functions and options does not guarantee the gadget one hundred percent serviceability. Quite often, users are faced with a problem when the computer does not see the phone via usb. Before you rush and rashly troubleshoot a fault, you should deal with its cause. Below will be considered the main ones.
The main reasons for the lack of contact between the phone and the computer
One of the main reasons for this malfunction may be a mismatch of software that is installed on the computer and the phone. Ideally, if you connect a gadget to a computer, you first install a program on it that matches your phone.
Many users of personal computers neglect the additional settings, not considering them to a proper degree necessary. However, you should understand that they greatly facilitate the interaction between the computer and the phone, without exposing the one and the other gadget to unforeseen risks. Therefore, it is always better to spend the extra half hour to install software that corresponds to the phone than to subsequently contact expensive specialists, or not be able to set up contact between the devices at all.
In the event that the smartphone manager is installed on the computer, but you still cannot see the connection, try restarting both gadgets at the same time.
Faulty usb wire or connector
Another fairly common reason why a connection between two devices cannot be established is a faulty connector.
If the connector on the computer is in working condition, then pay attention to the usb-cord. It is difficult to find a breakdown with the naked eye, even if there is one. Therefore, try to connect any other device to the computer. If the connection is not established, then the reason for the lack of contact between your phone and computer is a defective cord. In this case, you just need to buy a new one.
Another option is possible. You connected your smartphone to any other device, and the connection was established. In this case, things are much worse, because you need the help of a professional, without proper education, you can hardly fix the problem yourself.
Computer viruses
A strong virus can disable the whole system. The virus can spread to drivers - programs that are responsible for the functional connection. Accordingly, another reason that the computer does not see the phone via usb may be a viral lesion.
Better prevention of this kind of difficulty can be antivirus programs that are systematically updated and treat viruses, if any. Therefore, if there is no contact connection between the equipment, then check for the presence of viruses and that of the other equipment.
When viruses are detected, they should be immediately eliminated and then the gadgets should be restarted.
Firmware or driver malfunction
In most cases, the problem that the computer does not see the phone via usb can be solved by the drivers. There is a possibility that during the installation of the drivers any mistakes were made which caused such consequences.
Making sure that the drivers are in good condition, study the firmware of your phone for relevance. Perhaps it is outdated and requires a corresponding update. Do it yourself or consult a specialist.
How to prevent malfunction
Above were listed the main cases in which the connection may fail. In fact, they are much more, and conditionally they are divided into those with which you can cope on your own and those that only professionals can eliminate.
By taking certain measures in advance, you will be able to prevent a similar situation:
- Check your computer and phone for viruses in a timely manner and, if necessary, treat them. If you are not able to cope with this problem on your own, take the gadget to a service, preferably a company one.
- Avoid possible ingress of water into the connector or on the usb-cord. Otherwise, dry the equipment thoroughly with a hairdryer. Also protect your mobile devices from direct sunlight, they contribute to the imminent damage to your property.
- Make sure that a fresh update is always installed on your computer or smartphone.
- Before you connect a new phone to your computer, first install the software on it that corresponds to the smartphone company.
- Install drivers that match your work equipment.
What to do if the computer does not see the phone
No matter how trite it may sound, the very first thing that needs to be done in the event of such a situation is to restart both devices, having previously disconnected one from the other.
If your PC does not have branded software that matches the manufacturer of the smartphone, then take the trouble to install it. As mentioned earlier, this can greatly facilitate the interaction of devices.
If you found that the reason why the phone does not interact with the computer is in the usb-wire, then change it. Quite often, wanting to save some amount of money, users acquire Chinese wires. Their main characteristic is that they simultaneously fit all computers and do not fit either. If you have purchased such a wire, and it does not “come in contact” with your computer, then you can hardly do something with it.
It is likely that the reason for the lack of contact between devices lies in something more complicated, with which you can not cope on their own. It is likely that the case in a global computer crash, and here you just need a professional.
