What is the little hole at the top of your cell phone for?
In the last decade, mobile devices have become essential for people around the world, since through them people can connect with the beings closest to their lives, as well as carry out different day-to-day tasks, such as work, pay bills and make purchases, among many others.
In this sense, the companies that produce these devices add new technological functions, such as, for example, the famous hole found in the upper part of cell phones.
Now, the main function of this small hole is to receive the NanoSIM; However, another of its main characteristics, which is not so well known, is that it improves call quality, which is why you should not insert pins or a key to remove the tray.
Also, this hole works as an external sound insulator, that is, when the other person is listening, they will not hear too much noise around them, that is why calls are much clearer on smartphones, no matter if they have an Android or iOS operating system.
In the same way, there is the hole located at the bottom, which is known as the ‘Microphone Hole’ and is essential for the correct functioning of the phone, since it guarantees that the sound enters the cell phone, converting them into electrical signals. .
However, this hole can bring great complications to the cell phone. For example, the entry of dust and dirt into the mobile can lead to problems when capturing external sound. Similarly, it can happen that water enters the phone, causing serious internal damage.
How to clean this part of the cell phone?
To clean this part of the cell phone, the first thing to do is turn it off, then it is recommended to gently blow into the microphone hole, in order to remove the largest dust. Once the residue has been removed, the best option is to clean with a cotton swab soaked in a very minimal way with isopropyl alcohol. It is recommended to do this process once or twice.
Finally, once the cleaning process is finished, the most favorable thing to do is to let the alcohol dry completely and then turn on the cell phone. Also, this process should be done on a regular basis, in order to avoid serious audio problems in the future.
This is how you can block spam text messages on your cell phone
In recent months, phishing and data theft attempts, also known as phishing , along with other types of scams, have become commonplace in the text message format. Cybercriminals pretend to be a bank or some paid service through this format.
However, phone calls that are considered spam are already detected by mobile devices. However, text messages go directly to the mailbox without any inconvenience; However, the user can do something about it, no matter if he has Android or IOS operating system.
How to block spam in text messages on Android?

- Select the text message that you want to mark as spam.
- Click on the three dots icon located in the upper right.
- Click on ‘Block’.
- Next, press the ‘Report spam’ option and then select ‘OK’.
How to block spam in text messages on iOS?

Steps:
- Press on the device number as if you were going to make a call.
- Click on the contact information icon.
- Immediately afterwards, select the option ‘Block this contact’.
Likewise, the user can enter the ‘Settings’ and look for the ‘Messages’ option and activate the ‘Unknown numbers’ option. This function prevents the device from receiving messages from unknown numbers.
