Why phones no longer have the infrared with which you used to send photos and music?

Until a few years ago, the infrared sensor was one of the most striking features of the mobile phones. This functionality allowed one to share photos, videos or music in mp3 soon. However, it is an option that most smartphones modern ones no longer have it integrated and few know the reasons. Why were they withdrawn? Here we explain.

Finding the infrared sensor in current equipment is difficultsince most manufacturers consider it unnecessary and obsolete, since there are already options with which one can control all kinds of electronic devices thanks to the integration of the wi-fi connection.

Although years ago it was a very useful function for mobile telephony, it has disappeared from the strongest brands on the market. As such, its presence takes up a lot of space in the equipment design, so it is more convenient to use more modern systemswhich have smaller dimensions.

For this reason, if you are looking for a mobile device that has such a sensor, you will only find options that are outdated and they are no longer produced.

It is clear that companies stopped opting for this option in their products and that few users used it. The arrival of wi-fi and bluetooth optimized the interconnection between devices and the transfer of files in less time and with greater security.

In addition, it is a trend that will not change and the largest manufacturers prefer to devote their efforts to designing terminals with better autonomy, faster charging or better conditions for their cameras and screens.

Additionally, with wi-fi connectivity it is possible to have a universal remote to control devices and do it from the portability of the smartphone through an app that integrates all its capabilities. Without a doubt, it not only replaces the most popular infrared capabilities, but it goes a step further, in which it even relies on artificial intelligence to activate devices by voice command.

Why don’t modern phones come with FM radio anymore?

Before the advent of Spotify, YouTube Music and Apple Music, smartphone users listened to their favorite bands and artists through FM radio. However, over the years, this feature has stopped being included in modern mobiles, only some low-end models still have it. However, behind the manufacturers’ decision to disappear this component, which was previously considered essential, there is more than one reason. Which are? We tell you.

The fact that most of today’s cell phones no longer have FM radio is not only because the manufacturers consider it an obsolete feature, but there is more than one reason. Next, we detail it:

  • Better design: the design of mobile phones has changed, the devices are becoming more modern and thinner. Manufacturers consider the FM radio to be a clear obstacle for these purposes. For the FM radio chip to work it is necessary to have an internal antenna that takes up space that can be used for other features.
  • Outdated technology: Mobile manufacturers argue that times have changed and that FM radio is now an outdated technology that has been replaced by streaming music apps.
  • The business of streaming apps: streaming music apps like Spotify, YouTube Music and Apple Music have become the main alternatives for listening to music from a mobile phone. In them, users have greater control of the content they play, unlike FM radio. In addition, it generates economic benefits for manufacturers that are part of that market through its wireless headphones.

Why should you deactivate the bluetooth of your phone when you are on the street and you do not use it?

The bluetooth connection is a way that cybercriminals use to gain access to your smartphone. As such, you can be exposed to potential bluebugging, which occurs through gaps in the identification system. That way, they can read the content you send or modify the data.

Also, if you leave the feature running all day, you could inadvertently link to unknown computers and you won’t notice it right away. In those cases, you would be involved in a security and privacy problem, since your personal information would be shared with third parties.

Like any other function that is running, bluetooth, if you don’t use it, will consume your smartphone’s battery. If you don’t have a charger handy or want to preserve the autonomy of your device, try turning it off.

What is the quick settings panel on my phone and what functions does it have?

One of the most important features of our phones, whether Android or iPhone, is the quick settings panel that is usually located at the top of the cell phone screen. Although it is easily accessible, many users are unaware of its importance and all the tools it offers us. Through these, we can connect to wi-fi, mobile data, NFC and more. Do you want to know what functions it has? Here we detail it.

  • Wi-fi: it is the option of the quick settings panel that allows us to connect to the wi-fi network of our home or work.
  • Bluetooth – This has become a much-needed technology that is present in all modern smartphones. Through this alternative, we can link to other teams.
  • NFC: Short for Near Field Communication, this is a short-range, high-frequency wireless communication technology created for the exchange of data between two nearby devices.
  • Airplane mode: is a type of setting that, once activated on the mobile phone, causes all wireless connections on the device to be disabled.
  • Share screen: it is the option of the quick settings panel that is used to share what we are seeing on the cell phone on a larger screen, such as a smart TV.
  • Do Not Disturb: It is designed to turn off all mobile sounds, calls and notifications when you do not want to be disturbed. The difference is that, unlike airplane mode, in this one you will be able to set some exceptions.
  • Rotation: it is a functionality that, when activated, allows us to rotate the cell phone screen automatically.
  • Location: this option is related to the GPS of our team. Having it activated is very important for Google Maps and other apps that require geolocation.
  • Data: it is represented by two arrows, they are opposed and it is always necessary that it be activated to connect to the mobile data of our cell phone.
