Bluetooth does not see the device? How to solve a connection problem. Why Bluetooth doesn't work on Android

First, it’s worth clarifying what exactly is wrong with the module’s operation. Does it turn on and then there is a problem or does it not work at all? Depending on the original problem, there are several possible solutions.

Problem #1: turns on, but does not see devices

Go to your smartphone settings and check bluetooth connection, enable visible mode or look at the Discovery Timeout setting. Disable the timeout and after that your Bluetooth headset will become visible and the search will work.

Problem #2: turns on, but does not transfer files

Solution: update your Android version or install a special application.

If you have outdated version OS, then the BT module does not have a file transfer function. If system updates are available for your gadget, update. If there are no updates available, find bluetooth app Fle Transfer to Play Market and it will allow you to transfer files without problems.

Problem #3: won’t turn on at all

If the module does not turn on at all, but shows eternal loading, this may be due to a virus, a conflicting program, problems in the system or hardware failure. First, try rebooting. If the problem was a memory clogged with temporary files or a system glitch, a reboot will help.

If the reboot does not help, you will have to act more harshly and reset the settings to factory settings (hard reset). Pay attention! This will erase all data (photos, videos, audio) from the phone’s memory, so copy them to another location in advance. Do full reset possible in the settings. Depending on the device, the name of the folder may vary, but more often “Backup and reset”.

If this measure does not help, then the radio module is simply broken and only service repair will help. But if a Bluetooth headset, for example wireless headphones with a microphone Partner Soul, does not turn on on a completely new phone, it is better to replace the gadget under warranty.

We often encounter different problems in using a smartphone: after some regular update, glitches occur in some of the functions or some individual modules completely fail. In this article we will tell you what can be done if after Android updates Bluetooth doesn't work.

Finding out the problem

First you need to make sure that wireless module doesn't really work. To do this, you need to turn it on. This is done in the following way:

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 virtually no settings for the radio module in question. All required parameters responsible for correct work, 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 could not harm your device. Therefore in in this case It is not possible to configure the module itself.

To solve this problem, you should consider 3 reasons why this problem could happen.

Rebooting the device

The first step is to restart the device. This procedure can fix minor glitches or loops in the system due to clogged cache memory, as a result of which Bluetooth began to work incorrectly. This procedure will clear temporary files and possibly fix incorrectly working functions.

After restarting, try activating bluetooth. If the desired result is not achieved, you should move on to the next step.

Factory reset

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 removing changes to file system, which could introduce viruses.

Depending on the manufacturer and Android versions, this parameter may be located along different paths. Using LG with version 4.4 as an example, you need to do the following.

If this method also did not help, and you have official firmware installed, most likely the module itself could have failed. In this case, you should contact the service center for further clarification and correction of the problem.

If you updated your device to unofficial (custom) firmware, then you should look for a problem in it at the developer level, which requires special programming knowledge; it’s 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

The Bluetooth module starts, but after that an error appears and it stops working? Or can Bluetooth not even be turned on? Before you can solve the problem, you need to identify the underlying problem. We will build on this in our instructions. In this article, we'll look at three problems and see if you can fix them yourself.

First problem: the Bluetooth module starts without errors, but the tablet does not see other devices

Solution. Perhaps the reason for this behavior is the visibility settings. Let's go to the main Options your tablet, find the section with Communication, where the Bluetooth settings are located. Here we need to pay attention to two parameters: Other Device Discovery Timeout And Visible mode.

In the timeout settings, you can set the time during which your device will be available for communication with other gadgets via Bluetooth. Against Visible mode there should be a check mark - this means that the tablet is available for other devices.

Second problem: Bluetooth starts but does not transfer files

Solution. If you have old version OS, you can find a separate Bluetooth application or update Android to a more recent version. Most likely, the module is working, it just does not have a data transfer function. There is no way to update your gadget? Then let's go to Google Play (or its equivalent) and find the application Bluetooth Fle Transfer– after this you will be able to fully work with Bluetooth.

Third problem: can't turn on

Solution. First of all, try rebooting your device. Didn't help? Let's move on to a hard reset. If even after a complete reset the module does not work, then the tablet should be taken in for repair. Bluetooth may not turn on due to malware, conflicting software, a problem in the system or a breakdown.

After a complete reset, all files will disappear from your gadget’s memory, so don’t forget to save important information before reset. If Bluetooth does not work on a new tablet, then you should return it to the store - they will exchange it for a working device.

Let's look at the reasons why the Bluetooth module does not work on Android and try to solve the problem.

Bluetooth is rarely used to transfer files, but if it doesn't work on Android, then other problems arise - for example, you can't connect wireless headphones. If the icon remains unlit when you try to turn on the module, the cause may be physical damage or software errors.

Turning on Bluetooth

Before complaining about errors or damage, you should make sure that you turn on the module correctly. If Bluetooth does not transfer files or says that there is no pairing, look at its status in the Android settings.

3. Turn it to the "On" position.

The module will begin searching for devices available for connection. To pair, turn on Bluetooth on the second device. If you are trying to connect two smartphones, make sure that the Bluetooth status on the second phone is set to “Display for other devices”.

If you have previously paired, the device will be in the list. To add new pairing points, press the Search button when Bluetooth is turned on. After the first connection with confirmation, the device will appear in the list, so in the future you will not have to pair it again - you just need to turn on the module.

Bluetooth won't turn on

If Bluetooth doesn't turn on, shows error messages when trying to connect, or doesn't see devices when correct setting pairing, then look for a problem in the operation of the system and device.

But first try to solve the Bluetooth connection problem using one of special programs:

• Bluetooth Auto Connect.
• Bluetooth connect & play.
• Bluetooth Fix Repair.

These programs replace system tools using the Bluetooth module to establish a connection with other devices. If they do not help, then pay attention to the general condition of the system. There are no special ones on Android Bluetooth settings, therefore, measures to correct module malfunctions will be the most general:

On some devices, the problem with connecting via Bluetooth is becoming widespread. In such cases, the manufacturer releases a system update, after installation of which errors stop appearing.
