The method of using a Bluetooth headset in a free call in LINE can switch to Bluetooth either in a free call in LINE or in a call using a "Bluetooth headset", but in the case of proximity to the sensor, if it is "Bluetooth", it is also easy to send an image while talking. The recommended Bluetooth headset LINE's free call has unexpected sound quality.

Even outbound 4G/5G lines can become very useful. So, this is a very useful LINE free call, and did you know that even a Bluetooth headset that can make hands-free calls without a phone can be used?

As an app, you can send images from the gallery while making a free call with LINE, so summarize the tricks of how to use it.

There is no Bluetooth setting button on the screen, so it is difficult to understand. In fact, as long as you use Bluetooth to connect the phone and the headset for a "voice call", you can use the Bluetooth headset to make a LINE call.

However, the incoming call answer, final call, redial and other functions on the Bluetooth headset call button cannot be used. At present, we can only "talk".

Even when LINE calls when Bluetooth is off

You can switch to a Bluetooth headset during a call.

However, if the hand keeps the call screen close to the smartphone's proximity sensor (there are more types of phones at the top of the screen), the picture will disappear, so it is sometimes difficult to operate.

It's not as sensitive as it used to be, but if it doesn't work well, it may be easier to connect the Bluetooth headset frankly and then hang it up again.

When you switch to the conversation screen in a LINE free call, you can also use LINE conversation in the call state.

You can send not only text, but also images and maps as usual.

While talking with Bluetooth, you can see the same thing, so it's very convenient.

Although there are ways to switch to video calls instead of photos, the drawback is the decline in picture quality.

The line is in bad condition and can barely make a phone call. The same thing can be seen in such a place, and the photos may be more simple and convenient.

Camera function cannot be used during voice calls

During a LINE voice call, when trying to turn on the camera on the conversation screen

There will be such a mistake.

Really? You cannot use a camera during a LINE voice call. During a voice call, you can only send images from the gallery.

Dialogue screen "how to return to the voice call screen"

There are two ways to return from a conversation screen to a voice call screen.

The first method is to click the icon in the upper right corner.

The second is to click "LINE call" in the notification area.

You can also end the call directly by pressing "call end" from the notification area.

That's the trick of using it.

As long as you know this, you can make good use of Bluetooth in LINE.

Wait, wait,

However, this company's products have a lot of fake goods in circulation, it is best to use trusted stores such as large home appliance malls and domestic authentic products to buy, and after becoming Poly, the status of single-ear headsets is almost not published on the Japanese website, so it will become other manufacturers. I recommend the following models.

People who already use fully wireless headphones will accidentally use the call function, so it's better to try it first.

Although LINE gives people a light impression, but the call quality is very simple, although the delay is very large, but the simple sound quality is quite good.

Because there are people who hate voice calls, you can't talk to anyone (it should be said that LINE is mainly chat). Anyone can use LINE, and it will be very convenient if you can use Bluetooth to make free calls in case of emergency.

Recently, the call quota plan of SIM card is very popular, and calls of more than 5 minutes are free if they are LINE voice calls, which is also helpful to reduce the cost of voice calls.

A long time ago, we used things like BTmono and BTHeadSet to force the use of Bluetooth in Bluetooth incompatible applications. It was a really good time.
