Despite the fact that there is nothing and no one we spend more time with than our smartphone, the truth is that these devices are full of functions, tools, and sections that are completely unknown to their owners, or even if they have seen them on some occasion, they do not know very well what they are for.
Aspects such as shortcuts or widgets can make the phone usage experience more comfortable and faster, while there are other aspects that are more informative, but are equally useful because by understanding them we will know if the conditions in which we find ourselves are optimal for different uses.
For example, if you are expecting an important call in the morning, you know that it is necessary to have good coverage to receive it and have a clear conversation, and for that, you look at the section where they indicate the coverage in the form of bars where you know that if there are no bars, you are in trouble.
But, do you know what the up and down arrows next to the WiFi, mobile data, or Bluetooth icons at the top of your screen mean?
If you have ever noticed, or are looking at them right now, you will see that they are changing and sometimes appear and other times not.
What do the arrows next to the WiFi or mobile data icon mean?
In these cases, these two icons represent the two ways in which smartphones receive an internet connection. In case you didn’t know, the internet works based on the constant sending of data, and in these two cases, the arrows up or down show the path of the data.
When the arrows are pointing up it indicates the upload of data, while pointing down means that the data is being downloaded. For example, when you open TikTok and start watching content, it is normal for the down arrows to appear because the video data is being downloaded, and when we write a comment on that video, the up arrows will also appear because now we are the ones sending information to the internet.
And the arrows on Bluetooth?
But of course, Bluetooth has nothing to do with the internet connection, and therefore does not have the same meaning as in the previous examples. In this case, what these arrows represent is to show that there is a device connected to your mobile, this can be very useful to know if your headphones are still connected or not, although in terms of cybersecurity it can also alert us if someone has connected and it wasn’t us.
