I want to go over a very useful application for your phone. It is not always necessary to have all the newest features and improvements in the older version of the same mobile phone model.
The main question is whether it works fast enough and has enough memory left. What if you install an old version of a particular app? You will be able to check the Bluetooth version on Android with which you work. Let’s go!
what bluetooth version is my phone?
Let’s take for example a smartphone Samsung Galaxy J5 . Enter BLE Checker and look at the readings.
Approximate Bluetooth version: 4.1
The new version of the same phone: 5.0.2
Here we can see that it is not necessary to replace an old phone with a newer model just because you want to update your device’s functionality. You can safely use J5 without frustration.
You can also check which version of Bluetooth your headphones, keyboard or other device has. I checked my wireless mouse for work – the model is not very popular, but it supports version 3.0.
Approximate Bluetooth version: 3.0
Note that with BLE Checker you can find out exactly what version of Bluetooth your device has. You can find out whether you have version 4.0, 4.1 or 5.0+LE . With this information, you will be able to install the necessary app accompanying your device on your phone.
That’s it! with the help of BLE Checker , сheck Bluetooth Version On Android Phone is easy and quick.
the way it works and what we need
All you need is to download and install an application called BLE Checker . It uses the service of your phone’s Bluetooth adapter. The app itself runs in the background, reads data from it and sends it back to you via notifications. You can go about their business, read messages on social networks or just hide somewhere close by, but with your phone in hand and the screen locked. If you wish, you can also choose a more accurate version of the reading on the battery consumption page.
Checking the version of Bluetooth on Android:
The Bluetooth version installed in Android Lollipop 5.1 is 4.2 and supports both Classic and LE (low energy). Before this there was only the option of classic Bluetooth version, so old devices do not support low energy. By using a new device you can get better battery life because it does not require as much power to communicate with the phone.
If you want to check which version of Bluetooth your headphones, keyboard or other device has, you can use BLE Checker . Simply install the app and run it. As soon as it detects available devices, click “Start Service” and you will see all the necessary information about your devices in the notifications panel (version 4.0, 4.1 or 5.0+LE).
I am sure you have heard of Bluetooth and its uses. It’s a wireless connection that is used to transfer data or stream audio from one device to another without the need of any cable connection. And we all know what can happen if we try to connect incompatible devices (We know it by heart – The Blue and Red-Green flash).
Well, not all Bluetooth enabled devices are the same. They come with different capabilities and sometimes we need to find which one is yours? How do you do that? I will tell you how!
- Open Settings on your Android device
- Scroll down and tap on About Phone
- Now tap on Software Info and then tap Build Number repeatedly until you see a message – You are now a Developer! – Tap the Back key to enter Developer Options – Scroll down and look for Bluetooth version
- Optional: Tap on Bluetooth Share open all new window with bluetooth devices around you, How cool is that?!
Conclusion:
Since we can not determine the version of Bluetooth through software menu in our android phones, we need to download and install an app called BLE Checker . By using a new device you can get better battery life because it does not require as much power to communicate with the phone.
