Gone are the days when we used to transfer photos and more via Bluetooth. Although some people still use it for that purpose, it is being used for other useful purposes as well. Such as connecting with car infotainment systems or wireless earphones and headphones, etc. This is why the sight of the ZTE Blade A51 Bluetooth connection problem is daunting. Because this problem can prevent you from latching with any Bluetooth-powered device.
However, this isn’t the only Bluetooth issue you could face. There are other issues like your phone is unable to find other Bluetooth devices or the device got connected but there’s no audio or the connection keeps losing repeatedly, etc. If that sums up the Bluetooth connection problem on your ZTE Blade A51, here’s how you can actually fix it.
How To Fix ZTE Blade A51 Bluetooth Connection Problem?
Toggle Bluetooth option
It goes without saying, this is an easy-to-follow method that actually works in many cases. What’s happening here is that your ZTE Blade A51 didn’t engage Bluetooth when you asked it to and that is why you were able to connect automatically. Another explanation would be a minor software glitch that you can fix using this method.
- Bring down the Notification Pane.
- Tap on Bluetooth once to disable it (as it was enabled at first).
- Tap on it several times before engaging it and check whether your ZTE Blade A51 Bluetooth connection problem is gone or not.

- Tap on the “Airplane Mode” icon once to engage it and wait.
- After a few minutes, disengage it and turn on Bluetooth to pair with any Bluetooth device.
- Verify whether this troubleshooting method works or not.

Consider this situation, you connected to a Bluetooth TWS and called someone but there’s no audio. Alternatively, you have the audio but the built-in microphone doesn’t work. Perhaps both are working but you aren’t able to listen to any songs or audio from a video which seems odd. Perhaps, it isn’t odd but the settings made it do so. In your ZTE Blade A51 phone:
- Go to Settings >> Bluetooth >> Locate the Bluetooth device you connected to >> Settings (More Options).

Did you check for compatibility?
You should know that Bluetooth has different generations and based on which one your ZTE Blade A51 has and the device you are connected to, it may or may not connect. Latest Android phones are using Bluetooth v5.0 and so on while older devices might be using previous gen and the same goes for the Bluetooth device you are trying to connect to. Verify the generation and check for compatibility.
Apart from that, Bluetooth devices may have different ways to connect. Some would need a simple pairing, some would ask you to allow pairing while some would require a passcode flashed on one of the devices to enter on another one. Thus, you could be using the wrong method to connect so do check it out as well.
