What to do if Bluetooth does not work after updating Android

Every modern smartphone or tablet is equipped with a Bluetooth adapter that allows you to quickly connect devices to transfer data over a wireless network. In addition, Bluetooth allows you to use a wireless headset and connect to car speakers without using wires, which is very convenient. We described how to connect and use a wireless headset in a previous article. However, a fairly common question is why Bluetooth doesn’t turn on on Android?

It is worth noting that this radio communication is used quite often in everyday life. For example, to connect to a printer, audio equipment, to connect a phone and a computer, and so on. First you need to understand how to enable it.

How to enable Bluetooth on Android

To do this, you need to go to settings and select the Bluetooth category. On some models, you need to open the settings and go to the “Wireless Networks” section. Next, go to Bluetooth settings. To enable the adapter, check the appropriate box.

After this, the radio module will turn on and automatically begin searching for available connections. All you have to do is simply select the desired device from the list and click “Connect”.

All that remains is to confirm the connection. In this case, synchronization is only needed once. With further connections everything will happen automatically. As you can see, everything is extremely simple. But what to do if the Bluetooth adapter on Android does not turn on? Also see information on this issue here.

The problem “there was an error in the com.android.phone application” is still there

If the previous method did not help, you should try something else. For example, cancel date and time synchronization with the Internet. Very often this method really helps. This is done as follows: go to Settings, find the “Date and Time” section, in which you need to uncheck the “Network Date and Time” item. As before, we reboot the phone and try to access contacts again. I hope the com.android.phone error is gone this time (fly or any other smartphone brand has finally returned its top feature). If not, then we act like this.

What to do if the radio module does not turn on

First of all, it is worth noting that on the Android platform there are practically no radio module settings. In other words, you won't be able to configure anything. There is only one reason why the adapter does not turn on - a failure in the device’s firmware.

This means that there are only three options to solve this problem:

• Reboot the equipment.
• Reset to factory settings.
• The radio module has failed.

The fact is that all the settings that are necessary for radio communication on Android have already been entered and saved and you do not need to change them. Moreover, in order to improve security, such functions are hidden from users. This is necessary so that inexperienced tablet owners cannot damage the system.

So, first of all, before going to extreme measures, you should try rebooting the device. Very often, the reason why Bluetooth does not work on Android is due to minor glitches or system freezes. This can happen as a result of a clogged cache. A reboot is required for the temporary files to be deleted and the system to return to normal operating mode.

After this, try turning on the radio again. If this does not help, then you can move on to the next step - reset the settings to factory settings.

How to do a general reset on Android

On different versions of the Android platform, the data reset function may be located in different places. For example, on Android 4.4.2 you will need to go into settings. After that, open the “Accounts” category. At the very bottom of the menu you will see the words “Backup and reset”. Open this item and follow the prompts on the screen.

On earlier versions of this operating system, you will need to enter the settings, and then select “Privacy”. Here you will see the “Reset Data” option. Click on it. Next, read the hint. During the reset process, the device will reboot. This function may also be located in the “Restore and reset” section. The fact is that there are quite a large number of different versions of Android platforms. Moreover, each developer can change the interface at his own discretion.

As a rule, this procedure allows you to correct any problems, since all parameters are reset. Even if the reason is that you installed an application that disrupted the system or a virus entered the memory. If this does not help you, then it is quite possible that the Bluetooth adapter has simply failed. In this case, all that remains is to contact the service.

Results

Bluetooth still continues to be actively used, due to the increasingly frequent use of wireless headsets, headphones and speakers. Therefore, the developers of the Android operating system have made enabling and configuring it as easy as possible. In the latest versions of the Android OS, Bluetooth practically has only one setting - turn it on and off.

Why Bluetooth doesn't work on a Samsung phone

, if the owners have not recently experienced any crashes or failures of the operating system? Is it possible that the cell phone will now not work at full capacity, and some of its functions will become unavailable? Who will help you cope with a sudden disaster? How much time and money will be spent on restoring the previous, familiar, flawless functionality of a Samsung mobile phone? Why do such troubles occur that block the functionality of a communication device? The answer is below.

There may be one of the following malfunctions in the mobile:

1. Bluetooth does not work on Samsung because the Bluetooth module has failed. The situation is not critical, it can be easily corrected by resorting to the services of highly qualified employees of our telemama service center;
2. Samsung can't find Bluetooth because the antenna is broken. Only after a computer examination will the technicians understand what to do - repair a cell phone or restore it, change components;
3. Mechanical damage causes multiple breakdowns, including the appearance of cracks, rupture of contact groups, and other defects that need to be quickly eliminated with the help of professional repairs;
4. Cell phones are especially susceptible to getting wet. Naturally, the contact of liquid on the metal elements of the board is harmful, because even from school, everyone remembers where corrosion, rust, and oxidation come from.



So, Bluetooth is not working and you, as a responsible owner of a mobile phone, want to know why this unpleasant situation has arisen and how to get out of it. The main advice from the masters of our Telemama service center: while the reasons that provoked the incorrect behavior of the communication device are not known, do not try to interfere with the internal mechanisms yourself. The fact is that only free computer diagnostics show the real picture, which is not visible without testing equipment. The cell phone inspection procedure takes about thirty minutes and is not paid by clients.

After restoration procedures of any complexity, a long-term guarantee is certainly provided. Certification of the quality of work of our specialists is issued for a period of approximately one year, depending on the condition of the equipment and services provided. The cost of repairing Samsung products is so low that no other repair shop can compete with us.



Bluetooth is a wireless connection.

The purpose of the device is to connect different devices, as well as transfer and exchange files.

The adapter functions as a regular radio receiver, which is configured to send a signal and to receive it. Simply enabling the function will not be enough to work.

For the highest level of security, device detection is turned off. That is, in order for other opponents to see you, it must also be “activated”. Only after this the equipment is ready for use.

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.

1. Open settings.
2. Find the Bluetooth switch under Wireless & Networks.
3. Turn it to the "On" position.

Increase

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 on the second phone the Bluetooth status 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.

Finding out the cause

For example, if Bluetooth worked properly for a long time and then disappeared, then there may be several reasons for this: reinstallation of the operating system, failure or incorrect configuration of the drivers of this device, malfunction of mechanical switches, as well as malfunctions of the laptop itself, etc. To identify the specific cause of the problem and then eliminate it, you need to find out whether Bluetooth is turned on. You need to see if the Bluetooth indicator on the device is lit.

If the indicator is on and Bluetooth is running, but it still does not work, then you need to check the drivers. Go to the Start menu and open Control Panel. Here you need to find the “Bluetooth Devices” item. If the system shows that "Bluetooth Device" is not found or is not working, then a new driver installation will be required. Usually a driver disc comes with a laptop or external adapter. If such a disk is missing, then the drivers can be found on the manufacturer’s website, downloaded and installed from there. If the installation did not help, then most likely the problem lies directly in the Bluetooth adapter and this problem can only be solved by purchasing a new one.

Bluetooth won't turn on

If Bluetooth does not turn on, shows error messages when trying to establish a connection, or does not see the device when pairing is configured correctly, then look for a problem in the operation of the system and device.

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

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

• Complete reboot.
• Removing a folder with a MAC address from the /data/misc/bluedro directory >

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.

The most serious problem that a user may encounter is physical damage to the module due to mechanical stress or moisture. If connection problems occur after an impact, fall or swimming, contact a service center for diagnosis and possible replacement of the module.

On Android phones quite often there is a problem with Bluetooth. Most often, it is easy to fix. To do this, it is important to understand what kind of difficulty has arisen: the wireless connection does not turn on at all or problems arise during the process. I will tell you why Bluetooth does not turn on on Android and how to fix it, as well as what to do in case of other errors.

More options to fix com.android.phone

Although the android phone process and the Phone program are system ones by default, they can easily be replaced with third-party applications. They often change the appearance of the phone book and the screensaver for incoming and outgoing calls. Open the Play Market on your device and type “Phone” or “Dialer” into the search bar - based on pictures and reviews, you can find an application to suit your taste. After installation, we reboot the smartphone and check the operation of the application itself and our device. Personally, I installed ExDialer - Dialer & Contacts - this application has a nice interface and it copes well with the functions assigned to it. In addition, it has several design themes:

ExDialer - Dialer & Contacts

You can also clear cache data using the Aroma

. This option is suitable for users with unfinished and modified firmware, because “healthy” phone firmware using the second method described above.

Advice: do not forget to install anti-virus programs on your device; today, phones are much more susceptible to virus attacks than computers.

What causes the problem?

To know what to do when Bluetooth does not work on Android, follow all the steps from the very beginning:

1. Go to settings and turn on Bluetooth.
2. Select the device you want to connect.
3. If necessary, enter the pairing code.
4. Wait for the device to connect.
5. Use the device to transfer music, files, etc.

If a problem occurred at the first stage, for example, an endless process started, this just means that your Bluetooth does not turn on. There are no deep wireless settings on Android. You can only turn the module on or off. Therefore, you can correct the situation using fairly simple methods.

Device Compatibility

Among all the reasons, it is worth highlighting the use of different versions of Bluetooth, as a result of which pairing may be impossible. For example, a wireless device is equipped with bluetooth v.5, and your cell phone supports a set of protocols for version 3.

If you purchased regular wired headphones for talking and listening to music, the problems may lie in them:

• The wire is damaged. Visually this is not noticeable, but at a certain position of the cord the sound will appear, which will indicate a problem with it.
• Contacts are clogged. To diagnose, it is enough to shine a beam of light there and see if there is plaque there. If there is one, it can be cleaned with alcohol and a piece of cotton wool placed on a needle, but you need to be careful.

When it seems like the problem is with your headphones' wires, try connecting them to another gadget. If the sound is playing, you need to look for flaws in your smartphone.

Try special apps

If Bluetooth on Android stops working for you, the problem can be solved with special programs that correct compatibility, clean files or the system cache. These are apps like Bluetooth Fix Repair. The program copes well with the task, but there is a nuance: it only works with root rights. If your smartphone has not been flashed for this purpose, then you can try another application, such as Quick Fix.

1. Find it on the Play Store.
2. Download and install.
3. Restart your smartphone.

After these steps, the problem can be resolved.

Update system

The manufacturer may have already corrected this problem with your system. To achieve this, updates are released regularly. You can check this in Settings - System - Software Update. This will not delete data from your smartphone or void your warranty.

Another option is to reflash the device. In this case, you need to be able to flash devices or contact service methods

You can restore the functionality of your wireless connection by deleting folders with MAC addresses or clearing Cache and Dalvik Cache. You must perform this operation if you have root rights or custom Recovery. A malfunction is more likely to occur in such firmware than on standard Android. The folder with the MAC address that needs to be deleted is located in the /data/misc/bluedroid directory.

Reset

If other methods on how to turn on Bluetooth on Android did not work, and it still does not turn on, then the error is deeper. You will have to use a general system reset. This will delete all data on your smartphone, so be sure to make a backup copy and write down your Google account logins and passwords.

There are two methods to perform a reset:

• Using the menu: “Restore and reset” – reset settings.

• Through the recovery menu: turn off the gadget, press the power off + volume down button at the same time. The activation order may vary on individual models. A menu will appear in which you need to select “factory reset” using the volume buttons.

After the reset, the phone will return to its original state as it was when purchased. Most likely, the wireless connection will work.

Other possible problems

Sometimes the module turns on, but does not work correctly. If he does not see the device, or gadgets do not see the smartphone, or files are not transferred, then you can solve the problem using the following methods:

1. Enable visibility mode. To do this, you need to mark the appropriate position in the Bluetooth settings.
2. Disable connection timeout. Click on properties in Bluetooth connection. Usually these are three vertical dots. In the menu that appears, select a timeout and mark the desired time. If you cancel this option, the device will always be connected.
3. Check the gadget you are trying to connect to your smartphone. It must be put into pairing mode. This usually happens after a long press on a special button or the power button.
4. In older versions of Android, files cannot be transferred via Bluetooth. You have several ways to fix this: update the system, reflash the gadget yourself or at a service center, install an additional application. For example, the Bluetooth File Transfer program or similar ones will help to transfer files. You need to check which one will work on your device.

So, if Bluetooth is not working well for you on Android, don’t despair. There are many ways to correct the situation. First of all, make sure that you are doing everything correctly: Bluetooth is turned on, the device is in pairing mode. Then outline the problem for yourself and follow the steps indicated above. Your problem will definitely be solved.
