How to Connect M3 to Phone

Knowing how to connect the phone to a computer, you can use this opportunity to transfer data directly from one device to another.

And without the help of the Internet, and at a fairly high speed.

How to Connect M3 to Phone

This is necessary, for example, for transferring photos from a smartphone camera or multimedia files from a computer to a mobile device to a PC.

For most modern phones, there are several ways to connect.

Existing Connection Options

If you need to connect your phone to a computer, several solutions are possible.

The main options are:

  • Connection via USB port of a computer using a cable;
  • Wireless connection via WiFi;
  • Bluetooth connection.

The choice of a particular option depends on the reason why all this is done.

If, for example, you need to transfer a large amount of data (film,, or even a game application), the easiest way is to use a cable and a connection via a USB port.

The same method is best suited for using your smartphone as a webcam or modem.

Cord for connecting a smartphone to a PC via USB

Wireless connections allow you to connect faster, although they provide a lower information transfer speed.

They are also used if the PC or laptop has a Wi-Fi or bluetooth module, and the cord is not available at the moment.

Using WiFi

Connection via Wi-Fi can be called the most convenient and fastest in connection time.

At the same time, data transfer is slower, and for its implementation you will need either a WiFi router or an appropriate adapter.

There are several ways to connect a mobile phone to a PC, but the quickest and easiest of them is to install a special application.

There are variants of such programs for all operating systems, including iOS, and the principle of operation is almost the same.

One of them is a free FTP server application, which is freely available on PlayMarket.

After installing on a smartphone, the program requires starting, after which it shows the address that you want to write in the address bar of the “Explorer” on the computer.

This provides the ability to access the data of the mobile device as a regular folder.

Over, the user can change, delete and add new files on a removable disk, and in internal and external memory.

USB connection

When connecting via USB, the user gets the maximum of possibilities:

  1. Transfer data at high speed;
  2. Use a mobile phone to access the Internet using a GPRS connection or 4G network;
  3. Turn on your smartphone as a webcam and communicate using it, for example, in Skype. This option will be best for users on whose PC there is no camera.
    This is especially convenient, given that modern phones have image resolution at the level of the most expensive recording devices.

The disadvantage of this method is the binding of a mobile device to a computer.

At the same time, it will not be possible to call or go to another room from him at the same time as the data is being transferred.

All that is required to connect is a cord (usually microUSB / USB) and a free port on the computer.

In most cases, you do not even need to install any drivers. Just select the drive, modem or webcam mode on your phone.

It is even possible to use a computer as a charger.

Options for connecting a phone with Android OS to a PC via USB

When connecting the phone via USB with a cable, you can see a notification about connecting a new device at the bottom.

After installing the appropriate drivers (usually requires a PC connection to the Internet), synchronization ends automatically.

Bluetooth connection

If you have Bluetooth on your laptop or, which is now much less common on your PC, you can synchronize two devices using such a wireless connection.

To do this, both modules are activated and compatible devices are searched on the computer.

When the smartphone is found, it is connected via Bluetooth, choosing the option without using a passkey.

Helpful information:

To work with many devices with Bluetooth, we recommend using the program Blueoleil. This is a professional tool for pairing a computer or laptop with mobile and peripheral devices via a Bluetooth interface. Supports all versions of Windows, most smartphones, microphones, printers, TVs.

Possible problems

Sometimes when you connect or try, the computer starts installing devices and drivers. All that is required of the user is to wait until the process is completed.

If it was not possible to automatically install the control program, this is done manually.

Typically, the driver is located on the website of the smartphone manufacturer.

Sometimes there are situations when, for proper synchronization, you have to enable debugging on the phone. For this, the developer’s menu is usually used.

After debugging, problems with connecting to a computer disappear.

Some models of mobile devices with less common operating systems (for example, older versions of Windows Mobile or BlackBerry OS) may not immediately connect to a PC.

To fix the problem, the option can be helped in which the phone is turned off first, and then it is turned on, causing the computer to first determine the smartphone, and then automatically or manually install the drivers.

What if the connection failed?

There is another option for data transfer, which can be used as a last resort. For example, when there are no special applications, the cable is also there, and there is no access to the Internet from the PC or from the phone.

However, for this option you will need the presence of:

  • Removable flash cards (usually a microSD) on a smartphone;
  • Card reader on a computer or laptop (in the latter case, this probability is greater, because most even budget models have a reader for drives of different formats).

External microSD card slot on a smartphone

All you need to do is copy the data from the phone’s memory to a flash card, remove it from the device and insert it into the computer’s card reader.
