Bluetooth does not work on Android - what to do

Many device owners are wondering how to set up a Bluetooth headset on an Android smartphone and other gadgets that use wireless communication.

General settings

General setup instructions:

1. To turn on Bluetooth, you need to call up the quick access panel and activate the wireless connection.
2. Then start searching for visible devices and connect to the desired device.
3. Next, in the pop-up window, give your smartphone access to files and multimedia.
4. Go to the “Connected Devices” section and activate the “Internet Access” profiles to create a connection to the Network or “Contact Exchange” to transfer information about the phone book.
5. To disconnect the headset, just click on the “Unpair” tab.
6. You can also rename your smartphone and give it a different name.
7. The Received Files section will store items that were previously transferred. The “Previously Connected” tab will contain information about which devices were paired with. If you go to the “Advanced Settings” section, you can synchronize with peripheral devices.

Settings for controlling connected headsets and other devices

The “Advanced settings” item allows you to synchronize with the headset and other devices:

Additional functionality for managing the wireless protocol is contained in the “For Developers” menu. To call it, just follow a simple procedure:

1. Go to the “About phone” section in settings.
2. Then tap on the “Build Number” tab 5-10 times to activate the mode. After that, you can go to the “Bluetooth” settings for developers.

The “For Developers” option allows you to configure the connected wireless headset:

1. Go to “System” and “For Developers”.
2. Find the "Turn off Bluetooth volume control" option. This function will only be relevant if there are problems on remote devices, for example, the volume is too high.

Note! The “Select priority codec” parameter is responsible for the audio sampling frequency. The better the codec, the higher the quality of the transmitted sound. It is recommended to use this function when a headset is connected to the device.

“Audio channel mode” is responsible for transmitting audio in mono or stereo format, and “Bit depth” is for sampling the bit depth of the “A2DP” codec.

If necessary, the settings can be reset by clicking the “Reset settings” button at the end of the list.

Why do they resort to this procedure?

1. One of the reasons to use this option is to remove confidential information, for example, if you are selling your phone to another person and do not want any information about you to remain. In case of theft, this method will not work, but you can use the option to remotely control your device to erase data immediately after turning on the phone.
2. Another reason why settings are reset is the appearance of errors and problems of a systemic and software nature.

How to reset to factory settings on Android

There are three ways in total, and they differ significantly from each other. Let's look at each of them in detail:

1. Reset in phone settings
2. Resetting with service codes

All operations will be carried out from the main menu of Android OS. You need to go to the “Settings” item, select the tab called “Privacy” there, and then click on the “Reset Settings” tab.

As you can see in the photo above, here you can activate the following items:

Method 2. Reset with service codes

In the Android system, like in any other system (Java, Symbian), there are special codes with which you can activate the restore operation to factory settings.

Attention! Codes may change and may not be suitable for your model or version of Android, so perform all operations carefully! We are not responsible for all actions, and we provide information with codes for review.

The second way to find out which Bluetooth is built into the gadget is to use the “Settings” of the gadget. In many devices, developers add information about all the hardware installed in the smartphone or tablet.

Go to the Settings application, go to the very end of the list and turn on the Help menu. After that, open “Hardware Information”. This paragraph contains the following characteristics:

If you have any questions, please let us know

Ask a Question

• CPU;
• GPS version;
• RAM;
• Battery version;
• Version

So the most pragmatic way is to search for information on the Internet: by device processor or by the technical characteristics of a product in an online store.

Bluetooth settings in developer mode

This mode contains several functions that may be useful.

1. Show Bluetooth devices without names. This feature speaks for itself. If we turn off device names, we will only see their MAC addresses.

3. Launch the audio codec via Bluetooth. Allows you to select a specific audio codec from the list.

4. Selecting the sampling frequency for transmission via Bluetooth.

5. Select the audio encoding depth.

6. Audio channel mode (mono or stereo)

How to find out the Bluetooth version on an Android phone?

If you haven’t found such information, no problem, an application from the Google Play Market will help you. We will show an example using the CPU-Z utility, one of the simplest and most popular applications among other applications.

Install the application, launch it and in the first SoC tab you will see data on your processor. In our case, the MediaTek MT6582 processor is used:

Not a very convenient method, but it works. If you have other ideas to find the Bluetooth version, you can share them with us in the comments.

Google Phone app update breaks Bluetooth on Android

The main advantage of Android's modular structure is the ability to update key system applications without having to update the entire system. If Apple needs to update iOS completely to make any minor change to pre-installed applications, then Google can simply release a new version of the application on Google Play, from where users will install it.

This approach has many advantages, but there is one important drawback - this update scheme allows developers not to worry too much about testing new versions of programs. If there is some critical bug in iOS or in Apple's pre-installed applications, it will be impossible to fix it quickly, which is why Apple conducts such lengthy testing of its firmware, releasing many beta versions of iOS, which are tested by enthusiasts and developers. Google does not test as thoroughly, which leads to unpleasant consequences for users of its products.

The latest update to the stock Phone app, available for Nexus and Pixel devices, breaks Bluetooth. Google released this update on February 10, redesigning contacts, adding precise call duration, and a number of other minor changes. Not all users liked this update, as evidenced by negative reviews on Google Play.

Any design change always causes a negative reaction from a certain number of users, so such reviews should not be taken seriously, but, as Androidpolice pointed out, the new version of the application has a much more serious problem than the changed appearance of the application - the updated “Phone” simply does not work with Bluetooth connections.

More on the topic: How to access the service menu on Android?

If you use a wireless headset or connect your phone to your car system to make hands-free calls, it simply won't work at the moment. When I try to answer a call or dial a number by voice, the application does not respond. The most interesting thing is that installing an old version will not solve this problem. The update breaks something at the system level, so only Google can fix it. If you do not have automatic application updates, then we highly recommend not updating “Phone” if the operation of Bluetooth headsets is important to you.

If the application has already updated itself, then there is no need to panic. Bluetooth itself on the device will continue to function normally, wireless headphones will transmit sound, and other peripherals will work normally. The problem only affects the interaction of headsets with the standard Phone application from Google, which can be temporarily replaced with any other similar application from the Google Play catalog until the problem is fixed.
