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 intact. 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 have access to networks where data transfer rates reach incredible values.
To enable 4G you need:
- Go to the "Settings" section.
- There is a subsection "Other networks", which you should go to.
- 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 you will need to reboot the device.
As a result of performing the above actions, the settings will take effect, and you will be surprised by the increase in data transfer speed.

Fault description and remedies:
Have you noticed that does not see the Samsung Galaxy S4 network or the network constantly disappears and reappears - perhaps the following malicious factors and reasons are to blame:
1. The transmitter power amplifier is out of order (it must be replaced with a new original analogue);
2. The network on the mobile phone has disappeared because the radio path is faulty (you must first diagnose the cellular one, since many elements enter the path and it is difficult to understand which one is broken);
3. The gadget does not find the network due to a damaged antenna (it is advisable to replace the antenna with a new one);
4. If a liquid has penetrated into the apparatus (corrosion has begun) or some mechanical damage has occurred (strong shock, fall), then it is unrealistic to make a diagnosis without the results of the initial examination;

The other day, a friend of mine was faced with the fact that his brand new phone Samsung Galaxy J5 loses the network after a few hours of inactivity. For example, after lying down the night in the morning, the device has no network. Only a reboot helps, and then not for long, the edge - until the next night. The phone was handed over to the service for testing and, after a couple of weeks, returned as fully functional. I rummaged on the Internet and came across one similar case where the Samsung Galaxy S7 loses the network in about the same conditions. Thanks to him, we managed to find a solution to the problem! And now I will share it with you.
As it turned out, the LTE / 4G standard is to blame for everything. Or rather, not even so much he as the base stations of the telecom operator. In our case, it was Beeline. For some reason, probably only the manufacturer knows, the Samsung Galaxy phone loses the network if 4G / LTE mode is active. One has only to turn it off, leaving only 3G - the problem disappears and the message "No network" no longer appears, everything works like a clock.
How to turn off 4G Internet on Samsung
Perhaps later, with the release of a new firmware, the problem will be solved, but for now we have to look for such workarounds. So, to turn off 4G Internet on Samsung Galaxy, you need to go to the phone settings and select the "Mobile networks" section:
By default, all available modes are active there - LTE (aka 4G), 3G and 2G. If your Samsung Galaxy loses the network - try to put the option 3G / 2G:
After that, restart your phone and check. In our case, it helped and the problem went away.
Note: If the high-speed 4G standard is vitally necessary for you, then you should think about changing the operator. Moreover, now it is possible to do this while maintaining the number.
The flagship Galaxy S4 from Samsung, despite the fact that it is the best "life companion" (life companion in the sense), is technically very good, and there is a lot of good software in it, but the flagship also, as it turned out, breaks down, and quite often.
However, we will not talk about how often, but we will talk about the most common Galaxy S4 breakdowns. Fortunately, the relevant information and reviews on the forums and in service centers are now full, therefore, some conclusions can be drawn.
Overheat
In fact, overheating is, let's say, a common smartphone problem. Moreover, some of them even explode from overheating and injure their owners, but this happens, fortunately, infrequently. In general, it is definitely not worth considering this bug as a "sore" from which they only suffer.
However, it is known that most often cases of overheating were recorded on Galaxy S4 I9500 with XXUAMDE firmware. Symptoms in all cases are approximately the same: intense heat generation when charging the smartphone from the network or with prolonged continuous use, while, as a rule, reddening of the display is observed (i.e., the image on the screen has a reddish tint) and an increased body, which does not allow you to comfortably hold the device in hand. This is the kind of medicine.
As a first aid measure, experts recommend turning off the overheating Galaxy S4 and cooling it down by simply placing it on a table in a well-ventilated area, for example. If possible, you should also remove the back cover of the case for better ventilation. After the smartphone has cooled down, you need to check the firmware version and update it if necessary. This is done either wirelessly - through the settings menu (the "About device" tab and then "Software update"), or through the Samsung Kies PC program. If, after upgrading the firmware, the smartphone still overheats, then it is better to contact a service center or call a computer wizard at home.
Camera is buggy
The main camera of the Samsung Galaxy S4 is equipped with a very high-quality lens with a wide field of view, has many functions and allows you to take very decent (like for a smartphone) photos in different conditions and in different ambient lighting. But many Galaxy S4 owners complain that just high-quality pictures they do not get because of the incomprehensible "fringe" around the edges or blur.
In most cases, this problem is due to the fact that the camera lens is covered by a transparent protective film, which is actually not transparent enough and prevents the camera from working properly. Those. the film needs to be removed and several pictures taken, if it turns out to be of high quality, then the reason is in it. Otherwise, you will have to double-check the camera firmware version and update it. Again, if it was not possible to solve the problem with the quality of the images by using the camera, then this is another reason to contact the service center or call the wizard.
Suddenly slows down and / or freezes
The Galaxy S4, however, like any other smartphone, is not perfect, so it also knows how to lag and hang. The reasons for this may be different, but very often the TouchWiz shell and other Samsung software are to blame. Such bugs are also treated in different ways. Here are some of the most common ways:
- simple disabling of some Samsung applications or the entire TouchWiz shell at once : Settings -\u003e More -\u003e Application manager -\u003e All -\u003e Select all applications -\u003e Disable (or Settings\u003e More\u003e Applications\u003e Manager\u003e All\u003e Select the app\u003e Disable);
- clearing cache : you can delete unused and residual files, web search history, unused applications, unload the smartphone's RAM either through the same Application Manager (Settings -\u003e Application Manager -\u003e All -\u003e Select application -\u003e Clear cache, or Settings\u003e Application Manager\u003e All \u003e Select app\u003e Clear cache), or using a specialized program like Clean Master;
- restart Galaxy S4 : This procedure is recommended to be performed regularly, it allows you to update applications, "refreshes" the state of memory and improves performance.
Keyboard and auto-correct text
Taking into account the fact that many users are accustomed to the system of automatic correction of errors and typos and regularly use it when typing from the virtual keyboard, Samsung removed the standard Android 4.2.2 Jelly Bean OS keyboard from the Galaxy S4. But if the quality of the test auto-correction in TouchWiz does not suit you, then you just have to download other virtual keyboards from other developers (Go Keyboard or Swift, for example) and then check for updates to them without fail, since these applications also have their own bugs.
Signal quality
The Galaxy S4 sometimes gets in trouble with network searches and signal quality, just like any other smartphone. If such a problem manifests itself or manifests itself regularly, then you can first try to solve it yourself:
- better first re-check if Airplane mode is activated , since it is in this mode that the smartphone does not connect to communication networks, regardless of the signal quality (the offline mode of the Galaxy S4 is activated with the power on / off button);
- further necessary check signal quality ... Dense urban areas, thick walls, etc. will reduce signal quality, no matter how powerful your smartphone is. It is also worth making sure that at this particular place and at the moment the mobile operator's network is functioning normally. To deal with this, you can turn off the smartphone for 1 minute and, if possible, remove the SIM card and battery from it, then insert them back and turn on the device again;
- if this did not work to improve the connection quality on your Galaxy S4, then to solve the problem you will need consultation of a qualified specialist , i.e. the smartphone must be delivered to the service center or call the wizard at home. The built-in antenna may need to be repaired.
