Samsung galaxy s4 mini computer connection. Why can't my computer see my Samsung Galaxy phone via USB? What to look for

Without a doubt, the new flagship smartphone Galaxy S 4 of the famous South Korean giant Samsung opens an amazing window to the world of advanced technologies for users. However, you can make this window even more spacious and visual by connecting your gadget to a high-definition HDTV TV.

Of course, it is by far the largest smartphone of the company with an impressive 5-inch HD 1080p screen. Its display parameters satisfy almost all the requirements of fans of high-quality mobile video, lovers of web content, and even highly sophisticated gamers.

However, sometimes even such a large screen is not enough, especially when you have a modern 60-inch HDTV in your living room. Fortunately, today there are several convenient ways to connect your Galaxy S 4 to a TV that we will kindly share with you.

Using a wired MHL adapter

The most convenient and reliable way to connect your fourth generation flagship Galaxy S to your TV is to use the so-called Mobile High-Definition Link (MHL) adapter, which allows you to transfer all the information you see on your smartphone display losslessly to the huge screen of your home TV.

For about $ 40, you can get a Samsung branded adapter from the company's online store, or you can buy a similar device made by a third-party manufacturer for much less.

The main advantage of the MHL adapter is clear and uninterrupted transmission of high-quality video signal and multi-channel stereo sound. A relatively small drawback of this technology is the limited size of the connecting cable, so you have to get up from the couch periodically to control your smartphone connected to the HDTV.

Of course, not everyone may like this, especially if you want to show your relatives your favorite photos or short video reports about your vacation. However, for watching full-length films or listening to long musical compositions, this kind of connection is quite convenient and acceptable.

To connect a gadget to a TV, you will need an MHL-HDMI adapter, as well as an HDMI cable itself. The longer the HDMI cable you purchased, the more freedom you get to move around the room.

The MHL adapter connects to the micro USB port of your smartphone using the built-in cable. On the same side of the adapter there is a socket for connecting the gadget to it through a standard charger connected to an outlet. It's no secret that the mode of viewing high-definition video content is the most burdensome for the smartphone's battery.

By the way, not so long ago Samsung released a new adapter that supports the most advanced MHL-HDMI 2.0 standard, thanks to which the device does not require an external power source. Now you can connect the HDMI cable to the MHL adapter and connect the other end to the corresponding jack on the TV receiver.

To provide high quality transmission of an audio signal, you should do some manipulations in the phone settings. Sequentially enter the "Settings" - "Accessories" menu and select the "Audio output" section. In it, the "Surround Sound" tab should be activated.

Using the Samsung AllShare Cast Wireless Adapter

If you have been delving into the settings of your Samsung Galaxy S 4 smartphone for some time, you might have noticed the presence of the original Screen mirroring function in the gadget. It allows you to duplicate the information that appears on the display of your gadget on any large external screen. This ability can be useful for you if you are an avid gamer or like to watch exciting videos posted on YouTube with friends. This function does not restrict your freedom of movement within the room, and also provides convenience in viewing content on a large screen.

Among the obvious disadvantages of this technology, one can note the periodic loss of sound and image, as well as the discomfort associated with the sometimes occurring mismatch between the audio and video signals. In the case of using a smartphone as a game console, there are sometimes distinct image artifacts. It can also be more troublesome and expensive if you are trying to connect your Samsung Galaxy S 4 to third-party TVs.

The simplest and most reliable is to wirelessly connect your smartphone to a modern Smart TV from Samsung. You can also connect to the gadget of a branded South Korean Blu-ray player using Wi-Fi adapter AllShare Cast. However, this adapter allows you to wirelessly connect to your smartphone with almost any HD-TV. Note that this feature works well with Galaxy S III, Galaxy Note II and Galaxy Note 10.1 tablets.

To establish a wireless connection between your gadget and an external device, you must first connect the AllShare Cast Wi-Fi adapter to the TV. Then you need to go to the smartphone settings, go to the "Connections" section, in which to activate the "Screen mirroring" function. After AllShare Cast appears in the list of compatible devices, you just have to click on it so that the information displayed on the smartphone display is automatically displayed on the large screen of the HD TV.

As you can see, there is nothing complicated. It remains only to choose the type of connection that suits you in terms of convenience and price, and then fully enjoy the high-quality display of multimedia content.

It's no secret that the Samsung Galaxy has a microSD card slot for more storage. However, some users still additionally transfer pictures, music and videos to a computer or laptop. But what if the computer does not see the Samsung Galaxy via USB?

First, in order to recognize a smartphone like the Galaxy S, the computer needs all the necessary drivers. Usually, when a device is connected to a computer, it immediately finds it, but if the correct drivers are not installed, this may not happen.

Drivers are special programs that help you communicate between your phone and your computer. Most often they can be downloaded from the manufacturer's website. If the computer does not recognize your Galaxy S7, immediately go to the Samsung website and download the drivers. Here is the link to the Galaxy S7 / Edge. Mac owners will have to install in order for your Mac to interact with your phone.

There is an alternative: you can simply download and install the program on your computer, thus making file sharing easier. It comes with all the necessary drivers, so after installation you can rest assured that your computer will recognize your device and file sharing will no longer be a problem.

Those Windows users who have just installed Samsung drivers may find it necessary to uninstall the device before it is detected. You need to follow these steps:

Hold the button Windows and press R to invoke the command Execute.
Type “ devmgmt. msc" and press " Enter“.
Select “ Other devices" or " Portable devices”.
If the list contains “ SAMSUNG_ Android" or " Unknown device”With a yellow icon (!), Right-click and select“ Uninstall “.
Right-click on the " Device Manager"And select" Scan for hardware changes“.

Basically, after installing the necessary drivers or programs, everything should work. But if the problem is not that the device is not recognized by the computer, you need to look for another way.

Why can't my computer see Samsung Galaxy via USB?

If your computer does not see the Samsung Galaxy when connected using the supplied USB cable, then you will have to troubleshoot the computer itself. If you know that other computers can see the phone, it might be the USB port.

If this is not the problem, then the problem may be with the cable or the port for charging the phone has become loose. With all of this in mind, here are a few steps to help fix this issue:

Step 1: Connect your phone to other USB ports on your computer

Just connect your phone to your computer with a charging or data cable. If the phone remains invisible, try plugging it into a different port. Try one port after another to see if this was the problem.

Step 2: Reboot your computer if no USB ports are working

It is also possible that your computer has system problems that prevent it from detecting connected devices. While it is not known for sure whether this is a problem, you should restart your computer and see what happens. If the problem persists after rebooting, then something is wrong not with the computer, but with the cable or phone.

Nevertheless, I advise you to try other devices, such as a USB flash drive, that are connected via a USB port. If the computer sees all devices except the phone, proceed to the next step.

Step 3: Make sure the USB cable is not damaged

By inspecting the cable, you can check for visible damage. If not, try charging your phone with it. Inside the cable are wires that are responsible for both charging and data transfer.

By charging your phone with it, you can figure out if it works or not. If there is damage, the phone may not charge, especially if some wire has come off.

Another way to check is to use a different cable. If the phone works with it, then the native cable is simply broken. If this is really the problem, then you need to replace the old cable with a working one.

Step 4: Make sure to connect the device as a "storage device"

This is very important, as most phones are connected to a computer for recharging. If so, the computer may not see it as the melon transfer is temporarily unavailable. Go to notifications and see if there is a selection icon for USB. If so, consider that the problem has already been resolved.

All you need to do is click on it and select "Storage Device". If this is the first connection, then the installation of the drivers will take some time. But if you do not have such an icon, try the following:

Disconnect USB from Samsung.
Turn off your phone.
Wait 20 seconds.
Turn it on.
Reconnect the cable.
Check if the icon appears with options.

If not, proceed to the next step.

Step 5: check the charger socket

At a minimum, you need two cables to clarify if the problem is with it. If the computer still can't see the Samsung, it's time to check the charger port.

The connection may not be possible, or some debris, fiber, or dust has gotten into the connector. A flow of compressed air will help get rid of the latter, but if the connection is loose, you need to go further.

If the contacts of the charging socket are in order and there is no dirt, connect the cable and check if the contact has come off. If the cable goes in properly and the connection is not interrupted when it moves, then everything is in order.

Otherwise, you will have to purchase a cable that fits the port perfectly. If a new cable doesn't help, then your device is in much more serious trouble.

Step 3: Reset your phone if the problem persists after installing KIES or Smart Switch

The second step is aimed at solving the problem with the drivers, but if this does not help, you need to back up all files and information and reset the settings to a working state.

Turn off your Samsung Galaxy.
Press and hold the Home, Volume Up and Power buttons
When Samsung Galaxy appears on the screen, release Power, but continue to hold the other two.
When the Android logo appears, release all buttons and wait 30-60 seconds.
Use the Sound Down button to toggle between options and select ‘wipe data / factory reset.’
Press "Power" to confirm.
Then select ‘Yes - delete all user data’ with Volume Down and confirm with Power.
Wait until the end of the process. Then select ‘Reboot system now’ and click “Power”.
The phone will take a little longer to reboot than usual.

If after this the problem is not solved, the help of a specialist is required. I hope this tutorial will help you one way or another. If you feel you need more help, please contact us.

Last year, the flagship Samsung Galaxy S4 practically opened a window into the world of new possibilities for smartphones and many were new to see everything that Samsung's top smartphone can do. Galaxy S4 also knows how to connect to an HDTV TV if you have one of the more modern models. So you can enjoy games and movies not only on the juicy 5-inch screen of your smartphone, but also display the picture on your TV so that everyone can watch media content. If you still do not know all the features of the Galaxy S4 and do not know how to properly connect it to your TV, then we suggest you 2 easy ways that are available to almost everyone.

The first and easiest option: using the MHL adapter.

This is the most reliable and most convenient option for connecting the Galaxy S4 to a TV, however, you need to have a wired MHL adapter on hand that allows you to transfer the picture from your smartphone screen to the screen of your home HDTV TV.

The approximate price of a wired MHL adapter is $ 40, but that's if you decide to buy an official accessory. Third party manufacturers offer exactly the same adapters at lower prices.

The MHL adapter does an excellent job of streaming video and multichannel audio in excellent quality, which is its main advantage, however, the disadvantage of this method is the banal limitation of the adapter wire length, and therefore you have to come to your TV and the Galaxy S4 connected to it from time to time and manually switch videos or music.

I am sure that few will like this way of switching, especially if you are showing photos on the TV screen and you have to constantly sit next to it. If you want to watch a movie or just listen to music, then the MHL option of connecting the Galaxy S4 to a TV will be convenient and there will be no problems.

If you want a little more freedom, you can make it even easier - take an MHL-HDMI adapter and use an HDMI cable of the correct length. The longer the cable, the further you can move away from the TV.

A distinctive feature of the MHL adapter is the ability not only to view content from a smartphone on the TV screen, but at the same time to recharge the smartphone's battery, as high definition drains the S4 battery very quickly. You can connect the charger from the back of the adapter to a special connector.

However, the problem with recharging the battery while watching content on the TV screen disappeared after the appearance of the MHL-HDMI 2.0 adapter and additional source you no longer have to look for food.

When connecting the Galaxy S4 to a TV using any of the MHL adapters, we advise you to immediately go to the smartphone settings and set the high quality audio signal: Settings / Accessories / Audio Out / Surround Sound.

Method two: Using the Samsung AllShare Cast Wireless Adapter.

If you have had time to thoroughly study all the settings of your smartphone, you probably noticed that the Galaxy S4 has a "Screen mirrorring" option. It is specially designed to duplicate a picture from a smartphone display on an external screen, that is, on a TV screen. This will really appeal to game lovers or just to showcase videos to a large number of people on the big screen. At the same time, you are not limited by anything and can be almost anywhere (within the same room) and manage content from the smartphone screen with maximum convenience and simplicity.

But there are also disadvantages of this technology, which consists in periodic signal loss, loss of sound and picture, and sometimes the picture and sound may not coincide in timing, and even if you play on the Galaxy S4 and transfer the image to the TV screen using Samsung AllShare Cast or monitor, you will often notice strange image artifacts.

By the way, it will be a problem to connect Galaxy S4 using Samsung AllShare Cast to TVs of other manufacturers.

In general, we advise you to use the Samsung AllShare Cast option when connecting the Galaxy S4 to modern Samsung Smart TVs that already have built-in support for this service. You can also use the AllShare Cast adapter and connect your smartphone to a Blu-ray player, but again, it must be made by Samsung. Although, if you can already buy an AllShare Cast adapter, you can already connect the Galaxy S4 to any HD TV. This option has long been proven with the Galaxy S3, Note 2, and the Galaxy Note 10.1 tablet.

In advance, you should configure the Galaxy S4 Wi-Fi connection with an external device using AllShare Cast, then go to the "Connections" subsection in the phone settings and activate the "AllShare mirroring" option. After that, you will see a list of compatible devices on the screen, and all that remains is to select the one on the screen of which you want to duplicate the image from the Galaxy S4 display.

You see for yourself that there is nothing difficult, and there is a choice, and it depends on your capabilities.

Continuing the elimination of "android illiteracy", we decided to analyze one more question - how to set up the Internet on the Galaxy S4 S5 Note 3 Ace 3 and indeed all other Samsung Galaxy smartphones. It turns out that many users very often ask a similar question on our website, especially for "gray" devices, because the certified ones usually already have Internet profiles.

But let's take a look at what's what. Some simple information for beginners (noobs and dummies). So, you can go online from your phone in several ways: via Wi-Fi or a 3G operator's network (GPRS, EDGE, LTE, LTE-A).

1. Internet on Galaxy via Wi-Fi

This is the simplest and least expensive option. It can be said that it is not expensive at all, but it will not be entirely correct, since there are paid ones everywhere. Wi-Fi networks but there are many free ones as well. The easiest and most convenient way is to have your own access point at home. To do this, you need to go to a store or market and buy a router there, the cost of which will be 600 rubles. Then you need to contact your Internet provider and ask them to configure it for you.

But there is an even easier way - you can use Wi-Fi for free in shopping centers, cafe, and simply from a neighbor, asking for a password from his network. The advantages of such an Internet are free and high speed, stability.

2. How to set up 3G Internet

Everything is much more interesting here. First of all, it should be noted that in most cases 3G Internet is paid. Of course, there are unlimited tariffs, there are special offers with included megabytes (for example, Internet XS from Megafon) and others. For the correct operation of such an Internet, you need to check the data transfer settings, according to your OSS (operator cellular communication). To do this, you need to open "settings - other networks - mobile networks - access points" and see if there are any Internet profiles.

If they are, then all that remains is to turn on the data transfer in the "shutter". If not, you can configure it yourself or order network settings from the operator by calling him. In most cases, it is important to fill in only the "profile name" and "access point" fields.

The latter is decisive for most operators. Below we have given the value of this field (APN) for some of them:

Megaphone - internet
MTS - internet (there are different values)
Tele2 - internet.tele2.ru
Beeline - internet.beeline.ru and internet.beeline.ua (Beeline Ukraine)
Kyivstar - www.ab.kyivstar.net (for the Internet for 1 UAH per day) and xl.kyivstar.net (XL Internet)
Life - internet

3. What to look for

If you have completely set up internet on your Samsung Galaxy but it refuses to work:

Check account balance
Call the operator and find out which Internet service package is optimal for your tariff plan
Take advantage of online services, for example MegaFon Online to activate the data transfer service
Check the network coverage and if the GSM / WCDMA mode is enabled in the smartphone settings
Check your internet profiles again for item 2 above.

It is also worth noting that in order to save money and packet megabytes, it is advisable to turn off data transfer at night. It is very easy to do this by clicking on the switch:

The current flagship of the South Korean company Samsung is loved by many users for its support of high-speed 4G networks. However, some buyers are not even aware of this support, leaving the default settings untouched. As a result, complaints about low data rates and poor connections start. Below we will tell you how to use 4G on your Samsung Galaxy S4.

Separately, we note that a model under the code name i9500 is on sale in some markets. It does not support 4G, so nothing can be done about it. If you have purchased just such a model, then you can only sympathize. Only Galaxy C4 i9505 has support for fourth-generation networks.

If you are convinced that it is the i9505 that is in your hands (to do this, go to "Settings" - "About phone", and see what it says in the subsection "Model number"), then it's time to start taking action. After that, you will gain access to networks in which data transfer rates reach incredible values.

To enable 4G you need:

Go to the "Settings" section.
There is a subsection "Other networks" in which you should go.
Now click on the "Network Type" item. You will be presented with a list of available mobile networks. Among them there is also the item LTE / CDMA, which is needed in this case.
After that, all that remains is to click "OK", and the device will need to be rebooted.

As a result of the above actions, the settings will take effect, and you will be surprised by the increase in data transfer speed.
