The other day, one of my friends was faced with the fact that his brand new phone Samsung Galaxy J5 loses network after several hours of inactivity. For example, after lying down the night before 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 known to the manufacturer, Samsung phone Galaxy loses 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 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 telecom operator. Moreover, now it is possible to do this while maintaining the number.
Recently, periodically does not catch the network Samsung Galaxy S4 i9500? What to do in such unpleasant situations, who to turn to for qualified, professional help, support or at least advice? How to find out why the incorrect behavior of the considered high-quality portable communication device began? Bring your cell phone to our dedicated service center where:
Troubleshooting Samsung Galaxy S4 Network
Below you will find several useful instructions on how to improve the signal on your device, if you really need to. The more users a network transmitter has, the worse the signal. This is called "cellular respiration" - it decreases the radio coverage inside the cell as the amount of traffic increases. Operators also warn us about blind spots. Signal problems can also occur in the mountains, forests - trees can indeed be a very good signal blocker. When you hit the “blank spot,” it usually helps when you slightly change your position.
Highly qualified, professional craftsmen know how to fix a breakdown;
Quickly and at the same time completely inexpensively eliminate damage of varying complexity;
With the help of free computer diagnostics, they will see why there is no network on the Samsung Galaxy S4 i9500;
For installation, only original spare parts from the manufacturer's factory will be selected;
But what to do when you go looking for a signal that doesn't bring any positive results? Sometimes the easiest option is the best option. On the first network, you can still surf the Internet, although the connection may be smaller. Then tap Mobile Networks. Another more advanced option is to use a special device called a repeater, and its purpose is to amplify the signal. An external antenna picks up the signal, which is then transmitted over a communication cable to a device that is located inside the building.
The price of such a device varies and depends on the size of the building. It is usually quite small and you can place it anywhere in the room. Remember that the higher the antenna, the better the signal. If you need an antenna for a larger building, we would recommend hiring a company that specializes in this area.
They will provide a one-year warranty for the result of repairs and the quality of spare parts.
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:
The previously mentioned solutions are not guaranteed to be 100% effective. If you still have big problems finding a signal, we recommend changing the operator - maybe the cause of your problems lies there. It is normal that the message "No internet connection" is written in orange. If a blue checkmark appears next to your camera name, you are signed in.
For which environment?
Following are the basic steps to troubleshoot connection problems. Make sure you have the latest software for your device, app, and mobile device. Apply the camera as a new device.
- Select Forget This Device.
- Delete any camera registered in the app.
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);
Select the pencil icon on the left upper corner to delete the camera.
- Only the password can be reset.
- The camera informs you that the reset is complete and then turns off.
- Follow the pairing instructions.
- During the mapping process, you will create a new name and a new password.
- To reconnect, follow these steps to reset the camera password.
If all else fails, bring the camera to the service center to correct the cause. We specialize in all types of damage and remove them quickly. Touch screen, or, as it is called, touch screen is arguably one of the most important parts of a phone. Violation of this element is a real loss for the owners of these devices.
4. If a liquid has penetrated into the apparatus (corrosion has begun) or some mechanical damage has occurred (strong blow, fall), then it is unrealistic to make a diagnosis without the results of the initial examination;
5. There was a software failure, for some reason the operating system crashed (changing the firmware, installing a new version of the licensed OS will help).
Try restarting your device and turning it off. Nevertheless, it is recommended to contact the service center, where we solve the connection problem once and for all by placing a high-quality module in the phone.

Last year, Samsung listened to customers and began rolling out all-metal Android smartphones. However, the first pancake came out lumpy - tests showed that in the GALAXY A3 and A5 models, not everything is smooth with signal reception. It seems that Samsung has indirectly acknowledged this problem as it uses a new type of antenna in the GALAXY S6. Thanks to this change, the new Korean flagship is expected to be on par with other metal smartphones in reception.
According to Phonearena with reference to Korean media, Samsung is using a new type of antenna in its flagship GALAXY S6, which will solve the problem of unstable signal reception in a smartphone with an all-metal body. The GALAXY A3 and A5 models are equipped with LDS antennas, which, on the one hand, made it possible to reduce the thickness of the devices, and on the other hand, they could not make friends with the metal casing that was shielding, i.e. suppressed the signal of the cellular network and Wi-Fi. Samsung decided to get out of the situation by using flexible FPCB antennas, which will eliminate the influence of the metal housing on the signal strength and maximize the reception level.
Recall that earlier Hi-Tech.Mail.Ru conducted its own communication quality testing Samsung smartphones GALAXY A3 and A5. It turned out that the signal reception in the new metal smartphones is significantly worse than in the plastic devices of the Korean giant. This problem relevant both for the mobile network and embedded wireless modules... Under the same conditions with a SIM card of the same operator, Samsung metal smartphones show network reception on average 16-19 percent worse than the flagship GALAXY S5.
According to Nikolai Brandt, physicist and associate professor of the Department of General Physics and Wave Processes at the Faculty of Physics of Moscow State University, metal phone cases weaken external electromagnetic fields, and therefore phone manufacturers have to invent different ways to minimize the negative impact of the case on the call quality.
The Samsung GALAXY S6 will be shown at a separate event in Barcelona on March 1, ahead of MWC 2015. However, the as-yet-unannounced GALAXY S6 and S Edge are priced comparable to the Note line of tablets.
It is expected that the Samsung GALAXY S6 will receive a metal case, a 5.1-inch display with a resolution of 2560x1440 pixels, a new eight-core 64-bit proprietary Exynos 7420 processor with a Mali-T760 graphics accelerator and 3 GB of RAM, versions with 32, 64 and 128 GB built-in memory UFS 2.0. Unfortunately, Samsung has decided to ditch the expansion slot and removable battery. The latter will have a capacity of 2600 mAh, which is 200 mAh less than the S5 - the costs of a thin case. Also, the new Korean flagship will be deprived of moisture protection (in the S5 it is).
What are the networks for mobile communication
There are three generations of the network, the main difference is in the speed of the Internet. The higher the generation, the faster the Internet works:
2G (GSM, on the device is designated by the letter G or E) - the slowest Internet and the most low power consumption;
3G (WCDMA, designated as 3G, H or H + on the device) - average speed internet and average power consumption;
4G (LTE, referred to as 4G on the device) - Highest internet speed and average power consumption.
What are the network modes
Network mode is a rule (algorithm) according to which mobile device will connect to cellular network... By default, the device works in automatic mode:
If the device supports 4G and there is such a signal, the device will connect to it;
If the device does not support 4G or there is no such signal, the device will connect to 3G;
If the device does not support 3G or there is no such signal, the device will connect to 2G.
The ability to connect to one or another generation of the network depends on the device: if the device only supports 2G, then it will not work to connect to 3G or 4G. You can find out what network generations your device supports by contacting support.
In addition to the automatic mode, there are others:
3G only - the device will only search for the 3G network. If the 3G signal is weak or not there, the device will not catch the network.
2G only - the device will only search for the 2G network. If the 2G signal is weak or not there, the device will not catch the network.
There is no 4G only mode.
Some operators (Tele2) do not have a 2G network in certain regions (Moscow). Consider this when buying a phone - for example, Galaxy Star Advance only supports 2G and with Tele2 it simply won't work.
When is the network mode changed?
If you do not use the Internet, turn on the "Only 2G" mode - the device will drain more slowly.
If there are no 3G or 4G networks in the place where you are using the device, or the signal is very weak, turn on the "2G only" mode - the device will drain more slowly and the connection will be better.
In all other cases, it makes no sense to change the network mode.
How to change the network mode
Before changing, take a look Android version on your device.
If your Android 9
If your device is Android 8, 7, 6, 5
No "Network Mode" setting
The device only supports 2G, so this setting is not needed;
The device does not have a SIM card installed.
On a smartphone with two SIM cards, one always works only on the 2G network
This is normal operation of the device and cannot be changed.
A smartphone bought in another country does not work with my SIM card
V different countries operators use different frequencies for the same network generations. Before buying a device, check that the frequencies at which the communication works are the same. If the frequencies are different, then the communication will not work.
The Samsung Galaxy S4 is recognized as one of the most popular phones ever made. However, his popularity does not mean that he has no problems.

One of the methods to check the current state of the battery is to remove it from the smartphone and lay it out on a flat surface.
If it spins freely, if you rotate it around an axis (try to rotate the battery on both sides), then the bulge, which ensures the twisting, is the cause of the problem.
The easiest way, of course, is to replace the damaged battery with a new one, but it will not be superfluous to hand over the smartphone to a service center so that specialists can thoroughly check it and find out what caused the violation of its integrity.
Installation latest updates can solve many problems. If the battery physically looks intact and free from faults, then you should make sure that the phone and all applications installed on it have the latest updates.

Unexpected system reboot
Cases of self-rebooting of the phone indicate that there are some problems.
They can be associated with a violation of the physical integrity of the battery, for example, it can loose contacts.
Also, the reason for such reboots may lie in the software of the smartphone.
As already described above, checking and installing updates for applications can be a wonderful and fairly simple way out of this situation, or confirmation that non-updated applications have nothing to do with restarting a mobile device.
A memory card can also lead to development various problems related to the health of the smartphone. If you decide that you need to increase the amount of memory using a memory card, then be prepared for the fact that this can also become a source of problems.
