We often encounter various problems in using a smartphone: after some regular update, glitches of some of the functions occur or some individual modules completely fail. In this article, we will tell you what you can do if after android updates Bluetooth is not working.
Finding out the problem
First you need to make sure that the wireless module is really not working. To do this, you need to enable it. This is done in the following way:
- You need to go to the settings of your smartphone.
- Select "Bluetooth".
In some versions of Android, you first need to go to the "Wireless & Networks" item, and then select the "Bluetooth" option.
- After that, in the window that opens, activate the rocker, which is located on the top right.
After these steps, the wireless radio module should turn on and start automatic search available devices for further connection.
- To pair, you just need to select the desired device, click on its name.
- If you are pairing with this device for the first time, agree to connect.
- driver setup failure;
- malfunctions in the functioning of mechanical switches;
- reinstalling the OS, for example, XP on Windows 7/8/10;
- all sorts of software failures.
But if this module does not turn on, further actions should be considered.
If Bluetooth does not turn on
We would like to note that the Android OS has practically no settings for the radio module in question. All the necessary parameters responsible for the correct operation have already been entered into the system and there is no need to change them, since they are hidden from the user. This is done for system security purposes so that inexperienced users cannot harm their device. Therefore, in this case You can't configure the module itself.
To solve this problem, you should consider 3 reasons due to which this problem could happen.
Rebooting the machine
The first step is to restart the device. This procedure can fix minor crashes or loops in the system due to clogged cache memory, as a result of which Bluetooth began to work incorrectly. This procedure will clean up temporary files and possibly fix malfunctioning features.
After restarting, try to activate the blue tooth. If the desired result is not achieved, proceed to the next step.
Reset to factory settings
This method, as a rule, can fix any failures in the system by resetting absolutely all parameters, deleting all installed application, which could affect the operation of the module, or by deleting changes in file system that could introduce viruses.
Depending on the manufacturer and android versions, given parameter may be on different paths. Using the example of LG with version 4.4, you must do the following.
If this method also did not help, and you have the official firmware installed, most likely, the module itself could fail. In this case, you should contact service center for further clarification and troubleshooting.
If you have updated your device to an unofficial (custom) firmware, then you should look for a problem in it at the developer level, which requires special knowledge in programming; it is easier to replace it with a similar one or upgrade (or roll back) to any other official firmware for your model.
Bluetooth not working after Android update: Video
In this article, we will understand the reasons for the lack of communication (pairing) of the iPhone X/8/7/6 with BlueTooth accessories and what to do in such a situation.
Herself bluetooth technology is constantly evolving and there are more and more conflicts between devices. Those. in the same new iPhone versions the latest developments are used and there may be conflicts with accessories that work on older versions of Bluetooth, as a result of which they do not connect (no pairing).

And now let's look at the reasons why the iPhone is not looking for bluetooth.
Why the iPhone does not see Bluetooth
There can be many reasons for bluetooth not working. If the phone sees, tries to connect, but after some time you get a message that a failure has occurred - check if the device you are connecting to is active.
If it is active, it is most likely a system problem and then it will need to be corrected or complete reinstallation iOS. You can do this from yuekap (if any) or seek professional help from a service center.
In addition, if the iPhone does not connect via Bluetooth, you need to look at the signal range of the technology. If at a short distance (a few centimeters) the phone normally catches the signal and the transmission goes on, then the bluetooth coverage radius is very small. There are also cases of the opposite type, when Bluetooth on the phone connects and transmits normally at a distance of 5 meters, but refuses near it. This can be either a system problem or a problem with the module's emitter itself.
If such operation of the technology is inconvenient for you, you can visit our service center and fix this problem in a few hours.
The second reason an iPhone can't find another phone's Bluetooth is Apple's copyright policy. To make sure there is a file transfer blocking, connect a third-party bluetooth accessory (speakers, headphones). If the phone works fine with this equipment, then the copyright policy has affected your phone. But do not despair! The service center has the ability to install additional software, such as AirDrop, which works at the system level and allows you to bypass Apple's protection.
However, if Bluetooth iPhone does not find devices such as headphones and a headset, then the problem is already at the hardware level. Perhaps you have poor contact between the emitter and the board, or it turned out to be inoperative at all. Here you will need a full repair and opening the phone for hardware diagnostics.
Consider the situation when the laptop does not see the bluetooth device. There are many reasons, but we will consider the main ones.
If you need professional help - the masters of our service center in St. Petersburg are at your service.
Particular reasons for the lack of Bluetooth:
If bluetooth does not work, most often it helps to check the system settings, diagnose the operation of the drivers. From time to time, any equipment breaks down, in need of repair, adjustment or replacement. Programs as well as drivers should be updated periodically. Similar work should be carried out in a timely manner in relation to wireless networks transfer of information. Let's look at the basic causes of Bluetooth problems and how to fix them.
Is Bluetooth physically enabled?
To complete this task, you will need to check the buttons for sticking. If the switch is mechanical, the condition on the body of the device is checked. Modern computers have specialized indicators. When the Bluetooth mode is on, the indicator turns on in blue, while the switched off mode signals itself in red.
Bluetooth is on but not working
With Bluetooth on and off, you will need to check to see if the device is installed. To do this, visit the "Control Panel" located in the "Start" menu. Next, select "Hardware and Sound", "Add a Bluetooth Device". However, before you make this work, make the Bluetooth function on the third party device available. If you get a message that no devices are found, you will need to install the Bluetooth device one more time. If the device is found and Bluetooth is not working, try reinstalling the driver.
Reinstalling hardware drivers
In order to reinstall bluetooth drivers on a laptop, visit the "Device Manager" section, and then go to the "Bluetooth devices. The next step is to remove the integrated module. Then the laptop restarts, the system restores the drivers.
Installing or reinstalling drivers on a laptop
Often laptop manufacturers supply all required drivers complete with computer. In the event that such disks are not available, do not fall into despair: visit the pages of the official website of your laptop manufacturer, where you can download all the required drivers. You can also find drivers on third-party sites by entering a search query into your browser's search bar. Be sure to indicate in search query information about which variant is installed on the computer operating system Windows.
If nothing helps?
If the methods of troubleshooting problems with the visibility of devices on a laptop did not bring a positive result upon completion, it is recommended to contact a specialized service center. It is strongly not recommended to intervene in the repair process yourself by opening the lid of the laptop, trying to repair the equipment. Don't count on yourself if you can't set up Bluetooth on your own.
