However, many friends find in the process of using mobile phones, why do the 4G and 5G displayed in the mobile phone signal bar suddenly become "E", "HD" letters, and these letters pop up, what do they mean?
In fact, under normal circumstances, when we play mobile games, or brush short**, suddenly there is**dial in, then you will find that your own brush**, the game you play, will be disconnected from the network, stuck, but if you play**, the mobile phone signal bar shows "HD" such a letter symbol, then it will not be disconnected from the network.
In fact, "HD" means high-definition voice, and when the 4G network was first launched, many mobile phone manufacturers have already launched this feature!
HD is the mobile phone (VoLTE HD call) function, and the mobile phone ** is basically free and automatically opened, and can also be switched on and off in the mobile phone settings, if this function is turned on, then when we use the mobile phone to dial**, we can ensure that the sound quality is higher during the call, and the call is not interrupted during the network, and the user's experience is higher. And this voice call is free to open and receive calls, but if it is a high-definition ** call, then it needs 029 yuan for a minute.
So "HD" is clear to everyone, what is the meaning of the "e" in the mobile phone signal bar? When the mobile phone signal becomes the letter "E", the user can clearly feel the decrease in network speed, brushing**, loading**, will become very slow, so in the eyes of many netizens, "E" may be the network down to 3G or 2G network, but in fact, these are not accurate!
