Is there an HD logo in the upper left corner of your phone like mine? Do you know what it means? Are there any features that charge a fee? And how should we turn it off? I wonder if you have considered these issues. Please feel free to write your answers in the comment area.
First of all, let’s first understand what HD is. h d refers to vote high-definition voice call technology. That is to say, when the h d icon appears in the upper left corner of our mobile phone, it means that the user has activated the boat high-definition voice call function. So this function is generally provided by communication operators, so what specific functions does it have? So the first thing is to connect the phone faster. In the past, when we made a call, it took five to six seconds to connect. With the vote activation function, the time to connect a call is directly shortened to about two seconds. Then the second advantage is that the video and voice are clearer. After the vote function is enabled, the picture is relatively clear when making video calls.
As for the third advantage, I believe many people also have a deep understanding of it. That is, it will no longer affect the Internet while we are on the phone. You can talk on the phone while browsing the web, WeChat, reply to Taobao shopping, etc. It won't delay your work at all, unlike before when a call came in, you couldn't do anything except hold your phone and chat. For some users who love to play games, they can make calls while playing games, and there will be no network disconnection. So after talking about the three major advantages of vote high-definition voice calls, let's find out whether there is any charge for this hd function? The answer is no, there is no charge.
But there is one thing worthy of our attention. We will find that after making a call, there will be a video call button here. There is an additional fee for this. Many people also suffered from this disadvantage and pressed this button out of curiosity. As a result, they were deducted ten or twenty yuan in vain. Because it is charged separately, a one-minute video call costs 29 cents. That’s because we basically use WeChat for video chat now, so it’s recommended that you don’t use this function easily to avoid incurring high call costs. So at this point, someone may ask, can this function be turned off? How to close it?
The answer is of course yes, we open the settings of our mobile phone, then click on mobile network, then click on mobile data. As you can see, there is an option to vote for high-definition calls in this place. It is enabled by default. If you want to turn it off, just click the switch at the back. After turning it off, there will no longer be the h d logo above our mobile phone. Okay, that’s it for today. I wonder if everyone understands it?
