All Android phones come with built-in Bluetooth, but the specific version of Bluetooth that each mobile phone includes depends on the model and the date it was released. This leads many users to wonder if they can update that version to a more recent one and how to do it from your own device.
In this article, You'll see step-by-step how to update Bluetooth on AndroidYou'll learn exactly what can be updated and what limitations exist. You'll also learn how to Check the Bluetooth version that your mobile phone has, to understand the difference between Bluetooth hardware y firmware or driversand you will discover several advanced tricks for solving problems common connections with headphones, watches, cars and other accessories.
Warning! The Bluetooth version supported by the integrated hardware modem (BT 4.0, BT 5.0, etc.) is not the same as the Bluetooth driver or firmware version, which can be updated. For example, you might see a Bluetooth v5.0 version with a software version of v12; they are not the same. Updating the firmware can improve performanceto fix problems, and even eliminate vulnerabilities. That's why it's important to keep Bluetooth updated.
With all this clear, you can assess whether your device can take advantage of the latest Bluetooth improvements And what real options do you have if your mobile phone no longer receives system updates?
How to know the version of the Bluetooth of my mobile
El Bluetooth is still very important on Android devices. Although many connections are now made via Wi-Fi or cable, Bluetooth remains key for connect wireless headphonesSpeakers, smartwatches, fitness trackers, game controllers, computers, or your car's multimedia system. That's why knowing which version you have helps you understand What features and performance improvements You can take advantage.
There are different versions of this technology (Bluetooth 4.0, 4.1, 4.2, 5.0, 5.1, 5.2, etc.) and each one introduces improvements in energy consumption, greater reach, faster transmission speed or advanced features like low-latency audio or simultaneous connection to multiple devices. Before considering an upgrade, it's essential Identify the Bluetooth version that comes with your smartphone from the factory.
On Android, you have several ways to view this information: from the system settings, using specialized applications such as AIDA64 or by directly consulting the manufacturer's technical specifications.
View the Bluetooth version in the system settings
Some Android phones allow you to view Bluetooth information directly within the system itself, without installing anything. Not all models include this feature, but if your custom interface allows it, it's a very quick way to find out.
On many mobile phones, you can follow these steps to check the Bluetooth version using system processes:
- Opens Settings from your Android.
- Then go into the section Applications.
- Select option All apps or similar.
- Click on the three points from the right side and choose Show system processes o Show system apps.
- Search and select Share via Bluetooth or simply Bluetooth.
- In your record, locate the information field where the self associated.
In some models, the version shown corresponds to the driver or app versionand doesn't always directly reflect the Bluetooth hardware version (4.2, 5.0, etc.). Even so, it's a useful first indicator of whether your system is compatible. relatively updated or if you can have a very old version.
Use apps to view the Bluetooth version
Unfortunately, not all Android users will be able to take advantage of the above method, as it depends on how the manufacturer displays internal system information. For these cases, there are other options. specialized applications for displaying hardware data which are very useful for knowing what version of Bluetooth you actually have.
One of the most complete tools is AIDA64It's a very old and popular app that many users know because it allows you to see detailed processor informationmemory, sensors, battery, screen and also the device's connectivity.
With AIDA64 you can clearly see the Bluetooth version supported by your mobile phone following these steps:
- Download and install AIDA64 from the Google Play Store on your Android phone.
- Open the application after installation.
- In the main menu, tap on the section System.
- Within that section, look for the field Bluetooth version.
- You will see the supported standard indicated (for example, Bluetooth 4.2, Bluetooth 5.0, etc.).
The app gives us a lot of information about the phone, and among that data is... the Bluetooth version we haveThis way, you get the information you need without having to navigate through hidden menus or resort to strange codes.
If you want to know more about your phone and quickly check this information, you can download AIDA64 for free from the Google Play Store. Here is the link:
Check the official specifications of the mobile phone
Another very simple method to find out if your mobile phone is compatible with one version of Bluetooth or another is to Check the device's technical specifications.This information is usually available both in the manufacturer's official website as in technical specifications on specialized portals.
In this case, all you need to do is search the internet for full name of your mobile followed by the word “specifications” or “technical data sheet”. Once inside the product data sheet, scroll down to the connectivity section, where you will usually find a field called Bluetooth which will indicate something like “Bluetooth 4.2”, “Bluetooth 5.0 LE”, “Bluetooth 5.2”, etc.
Some points to keep in mind when consulting this information:
- It is preferable to use the manufacturer's official websitewhere the data is usually more up-to-date and more reliable.
- You can also use trusted third-party pagesprovided they have a good reputation and update their listings frequently.
- If your mobile has received major system updatesIt is possible that some external websites may not reflect minor firmware changes or additional features, so this method may be somewhat less accurate than using an app like AIDA64.
This method is very useful if you don't want to install anything on your phone and simply want a quick reference to the Bluetooth version that includes the hardware.
What is the difference between a hardware version and a firmware version?
It's important to understand that when we talk about Bluetooth on a mobile phone, we're actually talking about two different levels:
- La Bluetooth version of the hardware (for example, 4.0, 4.2, 5.0, 5.2), which depends on the physical chip integrated into the device.
- La driver or firmware version Bluetooth, which is the software that manages that chip and can receive updates through the operating system.
El hardware determines the maximum limit of what your Bluetooth can do (range, maximum speed, supported technologies), while the firmware allows refine performance, improve stability, correct errors, optimize consumption and close security vulnerabilitiesWhen you update your mobile phone, what changes is mainly this software part, not the physical chip.
This means that even if your device has Bluetooth 4.2 hardware, for example, you won't be able to convert it to Bluetooth 5.2 via software. What you will be able to do is improve their behavior within the limits of that specific standard.
How to update the Bluetooth of my mobile
Many users want to know how to update Bluetooth on their Android devices to get the most out of them. wireless headphonesSmartwatches, speakers, or the car's hands-free system. It's only natural to always want to have the latest possible version of the driver to avoid audio cuts, pairing problems, or sudden disconnections.
To update Bluetooth on Android, what you really need is Update Bluetooth drivers These drivers are included in your system. They are part of the operating system, so they cannot be installed independently as they can on a Windows PC.
In Android, controllers are not managed separately from a user interface. There is no official “Bluetooth driver updater” There is no option in the settings to manually install a driver for this connectivity. Driver updates are always linked to a operating system update or, sometimes, to a security or maintenance patch distributed by the manufacturer.
Therefore, if you want to update your mobile phone's Bluetooth, the first thing you must assume is that the only official and safe way To do this, go through keep Android updated with the latest versions released by your device manufacturer.
Check for available system updates
In this scenario, the most important thing is check frequently If you have an Android update available for your phone. Each new version usually includes stability improvements, kernel changes, security patches, and very often, hardware driver updates, including Bluetooth.
Your Bluetooth driver will update automatically. along with the rest of the system components, without you having to do anything extra. To check if your phone has an operating system update available, you can follow these general steps (the names may vary slightly depending on the brand):
- Opens Settings on your Android.
- Go to section Systemalthough its location and name may vary (sometimes it appears as About of the phone o System information).
- Look for the option Upgrade system o Software updates.
- Tap on Search for updates o Check for updates.
- If you detect a new version, click on Download and install or the equivalent option.
- Wait for the download and installation to finish. The device will restart and The entire system will be updated, including Bluetooth drivers.
In some customization layers, you can also enable options such as automatic search for updates and scheduled installation when the phone is charging. This helps keep critical components like the Bluetooth module without you having to worry about checking it manually.
What happens if my phone no longer receives updates?
One of the major drawbacks of the Android update model is that Many phones stop receiving official updates After a certain time, as soon as the manufacturer stops providing new system versions or security patches, your phone will... freezes with the Android version and drivers you have at that time.
This means that Android phones that don't receive updates They also won't have new versions of the Bluetooth firmware.This is a significant limitation, especially for users who:
- They have a low-end mobile phone which barely receives updates.
- They use a phone several years old whose official support has ended.
- They depend on very specific Bluetooth functions, such as low latency audio for games or stable connectivity with the car.
In some cases, Google or the manufacturer itself publishes intermediate updates (security patches, maintenance updates or bug fixes) which also include Bluetooth controller improvementsThese updates do not change the main version of Android, but they do adjust low-level components that can fix problems such as disconnections, noise, audio dropouts, or incompatibilities with new accessories.
However, this isn't always the case. Many devices that have been on the market for a while stop receiving even these updates. minor updatesIn those cases, even if you continue using the phone without problems, the Bluetooth module will remain on the same firmware version forever, with the limitations and potential failures that I have at that moment.
Safely update Bluetooth and other system components
In addition to installing system updates when they are available, it's a good idea to adopt some habits to ensure that the The Bluetooth module and the rest of the system are updated successfully and without errors:
- Keep enough free space in internal memory before installing an update, as system packages usually take up a lot of space.
- Try to perform the installation with the mobile charged or connected to the charger, to prevent it from turning off in the middle of the process.
- Do not turn off your phone while it is updating, as this could cause system errors that affect components such as Bluetooth, WiFi or the mobile network.
- After a major update, it's a good idea restart the device one more time When everything is finished, to make sure the new drivers load correctly.
If after an update you notice serious Bluetooth problems (for example, constant disconnections with all devices), you can try to do a reset network settings From the system settings, which resets WiFi, mobile data, and Bluetooth settings without deleting your personal files.
Check the update schedule
One of the most significant limitations The reason Bluetooth updates on Android are linked to operating system updates is that You may have to wait quite a while. until a new version is released. And it might never arrive, if the manufacturer decides not to update your specific model.
When a new version of Android is released, most brands publish a update schedule for your devices. That calendar indicates which models will receive the new version And, in many cases, a reference is given to the month or quarter in which the update is planned to be released. OTA (Over The Air).
If you check this calendar and see your mobile phone listed, you'll know that You will receive an update at some point. which most likely includes Improvements to the Bluetooth moduleHowever, if your model is not listed, it is most likely that your device is no longer supported and will not receive new official Android versions or driver updates.
To make the most of this information, it is recommended that you:
- Check the manufacturer's official website, in the news or support section, where the calendars are usually published.
- Review forums and user communities for your brand, where things are often shared actual deployment dates and experiences after the update.
- Check if your model has official commitment of years of supportThis is something many brands detail to inform you how many Android versions and security patches you will receive.
This way, you can know with reasonable accuracy whether your Android phone will be able to obtain and use it. new Bluetooth featuresOr, on the contrary, will you have to settle for the current version and its features?
In models with good support, holding the phone for longer also means enjoying the performance and security improvements that arrive via Bluetooth controllers. This can make a difference in the experience with your headphones, smartwatch, or car sound system.
Fix Bluetooth problems before thinking about changing your phone
Often, when a user notices that Bluetooth It works badly (choppy audio, noise, random disconnections, or difficulty pairing with the car), think that the problem is solved on its own Updating Bluetooth or by buying a new phone. However, many of these problems can be fixed with adjustments and maintenance steps before reaching that point.
A typical example is that of a somewhat old telephone that suddenly starts to have "raspy" audio or dropouts when using Bluetooth headphones, while those same headphones work perfectly on a newer mobile phone or PC. In these types of cases, the following may be involved: interference with the WiFi networkPairing problems, incorrectly configured audio profiles, or simply errors accumulated in the Bluetooth cache.
Before you give up, it is advisable try to stabilize the connection and improve audio quality, both with headphones and with car sound systems or other accessories.
Step 1: Delete paired devices from the phone's memory
Over time, many mobile phones accumulate a huge list of paired Bluetooth devices (Headphones you no longer use, cars you no longer own, old speakers, etc.). This list can cause conflicts, especially if some accessories try to connect automatically or if audio profiles are incorrectly saved.
To clear this list and start from scratch:
- Open the Settings from your Android device.
- Sign in Connected devices o Bluetooth.
- In the section Paired devices o Saved devicesFind the ones you don't use.
- Tap on each one and select Forget, Unlink or the similar option to remove them from memory.
Removing old devices reduces potential errors and helps the system manage more efficiently. cleans and stabilizes new connections.
Step 2: Remove the phone from the car's memory
If you're having problems connecting your phone to the car (audio cuts, frequent disconnections, hands-free that doesn't activate properly), it's also recommended delete the phone from the car's Bluetooth system memoryIn these cases, it is helpful to consult guides on Android Auto and audio problems to better understand how the mobile phone interacts with the multimedia system.
To do this, you must follow the specific instructions of the your vehicle manualHowever, in most cases the process includes:
- Access bluetooth menu from the car screen.
- Open the list of linked phones o paired devices.
- Delete all phones that are not being used.
- If your current phone was already linked, delete that record as well to force a new clean link.
Doing this on both devices (mobile and car) avoids conflicts because old matchmaking information that may be interfering with the current connection.
Step 3: Update the device list and re-pair
Once you've cleared the list on both your mobile and car (or any other device you're having trouble connecting to), it's time to perform a new pairingThis also applies to speakers, headphones, watches, or any accessory that is malfunctioning.
To find out whether you should pair from your phone or from your car (or from the accessory), consult the your device's manualIn general, the steps are usually similar:
- Activate pairing mode in the accessory (in the car, usually from the Bluetooth menu).
- On mobile, go to Settings> Bluetooth o Connected devices.
- Tap on Pair new device or search the list of Available devices.
- Select the accessory name and follow the on-screen instructions (sometimes this includes entering or confirming a PIN, such as 0000 or 1234).
This will create the connection from scratch, using the current system configuration and reducing the likelihood that problems are due to remnants of ancient pairings.
Check for device and accessory updates
In some cases, Bluetooth problems don't just come from the phone, but also from the accessory itself: headphones, watch, speaker, etc. If the accessory manufacturer offers a official app (for example, for headphones or a wearable device), it's a good idea to check if There are firmware updates available for the Bluetooth device.
Similarly, make sure your mobile phone and accessory have the latest software availableMany accessory manufacturers release updates that improve the compatibility with newer versions of Android and correct connection errors.
For mobile phones of certain brands, it is also advisable to visit the support pages where it is explained How to update your phone to the latest software versionsince in many cases these steps include specific recommendations to improve Bluetooth performance.
How to properly activate, deactivate, and manage Bluetooth on Android
Although it may seem basic, properly managing Bluetooth settings also helps to avoid errors and better understand how this connectivity works in your daily life.
From the application of Settings On Android you can:
- Turn Bluetooth on or off by swiping down the notification bar and tapping the Bluetooth icon.
- Save money battery Turn off Bluetooth when you're not using it, because even though its power consumption isn't very high, it adds up along with that of other connections.
- View and manage the paired devicesdisconnect them, rename them, or define the type of device (headphones, car, speaker, hearing aid, others). To learn how change the name of your mobile To ensure it appears correctly on other devices, follow the guide provided.
Some Android devices also allow you to select the type of audio device associated device (speaker, headphones, car, hearing aid, other). Defining it correctly can enable improvements such as spatial audio or functions of measurement of hearing health and loudness, depending on the combination of mobile phone and accessory.
When you pair an accessory compatible with technologies such as Quick pairingRemember that this can be associated with your Google accountThis makes it easier for other Android devices linked to that account to connect. automatically recognize the accessory and offer to pair it without repeating the entire manual process.
If you don't want to receive constant notifications from nearby devices, you can go to your account settings and disable options such as Find nearby devices or limit Quick Pair notifications, without affecting the basic operation of traditional Bluetooth.
Even if your phone's Bluetooth hardware version doesn't change, keeping the system up to date and applying all these best practices will allow you to get the most out of wireless connectivity of your device and minimize pairing or audio quality failures, even on phones that no longer receive major Android updates.
