How to find out what Bluetooth version your Android phone or tablet has
Knowing the exact Bluetooth version installed on your phone is a critical step before considering any type of update. There are several methods to find out:
Check the version from settings and developer mode
On some Android models, it is possible to check the Bluetooth version directly from the system settings.The process may vary slightly depending on the brand and customization level of each manufacturer, but it typically goes as follows:
- Open the app Settings on your Android device (gear icon).
- Go to section Applications and select All applications.
- Click on the three dots in the upper right corner and select Show system processes.
- Look for the option called Share via Bluetooth or similar.
- Inside you will see detailed information, including the bluetooth version supported by the phone.
This procedure may not be available on all Android devices or systems, as some brands hide these options or relocate them to other sections.
Use diagnostic applications such as AIDA64
If the previous option is not active on your mobile, you can use specialized apps such as AIDA64, which are capable of displaying the installed hardware and software without the need for root permissions or complicated processes.
- Download AIDA64 from the Google Play Store or external secure sources.
- Open the app and go to the section System.
- Scroll down until you find the section Bluetooth version.
- AIDA64 will display the exact version supported, along with other useful information about your hardware.
This option is highly recommended, as it also provides you with other relevant technical data (CPU, RAM, sensors, storage, etc.) without taking up much space or requiring advanced access.
Check the specifications on the manufacturer's website or databases
Another easy way to know the Bluetooth version of your device is look for the official technical specifications:
- Go to your mobile phone manufacturer's website.
- Find the exact model and check the technical sheet, which should indicate the Bluetooth type and version.
- There are also specialized websites (such as GSMArena, Kimovil, etc.) that compile specifications for all mobile devices on the market.
This method is useful if you don't have the phone in your hand yet or if you want to check before making a purchase, but it may not reflect improvements received via updates if they have been applied.
Why does the exact Bluetooth version matter?
The latest versions—such as Bluetooth 5.0, 5.1, 5.2, and 5.3—offer notable improvements compared to the previous ones (4.0, 4.2, etc.), such as:
- Greater capacity for data transfer speeds.
- Improvements in stability and signal range.
- Significant reduction in energy consumption, ideal for wearables and headphones.
- Support for more devices and new multi-connectivity features.
If your mobile already has Bluetooth 5.0 or higher, you'll likely enjoy all of these benefits, so you won't need to look into additional upgrade steps unless you experience issues.
Is it really possible to update the Bluetooth version on Android?
The most frequent doubt revolves around the possibility of Update the Bluetooth version of an already purchased phoneIt is important to clarify some key technical aspects:
- The Bluetooth version depends on the physical hardware installed in your mobile phone.The Bluetooth chip built into the device determines the maximum supported version.
- operating system updates (Android) and firmware updates may improve the stability, security and performance of the Bluetooth module, but will not change the supported physical version.
- It is only possible to "update" the Bluetooth version by purchasing a newer hardware device or, in some very specific cases, by using external USB/Bluetooth accessories (more common on PCs than on mobile phones).
- There are no apps or patches that can increase the Bluetooth version on the phone's original hardware.
This means that even if the system receives improvements in the driver or software, if your device has a Bluetooth 4.2 chip, it will not be possible to make it work as a Bluetooth 5.0 chip with just an Android update.
What can be updated?
What you can and should keep updated is the firmware and the operating system., as:
- Fixes potential Bluetooth connection, security, and performance issues.
- They provide patches to increase compatibility with newer devices and accessories.
- They can enable additional chip functions, if the hardware supports it (although without modifying the base version of Bluetooth).
Therefore, although the version update as such is not possible, Keeping your Android system and apps up to date is essential to avoid problems and take advantage of all possible improvements..
How to update Bluetooth on your Android phone (drivers and system)
To update the Bluetooth drivers and get the latest improvements provided by the manufacturer, you must perform a full Android system update. This update may include:
