For years, we used infrared emitters and receivers, but with the arrival of smartphones, they were replaced by IR "blasters" capable of operating devices with an IR remote control receiver. However, this feature suddenly became almost obsolete. It's a disappointing turn of events, and here's why.
The Mystery of Why IR Blasters Left Us
Unlike headphone jacks, which have valid arguments for their elimination, the reason behind the removal of IR blasters in smartphones remains unclear to me. It appeared that these blasters were present in one generation of phones and then suddenly, there was a general consensus that they were no longer necessary.
The Samsung Galaxy 6 was the last phone in the immensely popular mainstream series to include an IR blaster. Unfortunately, I could not find any official explanations or announcements regarding the discontinuation of this feature. However, I believe it could be attributed to a combination of factors.
Bluetooth and Wi-Fi are better for transmitting data.
Most users probably didn't take advantage of the feature.
The internal space was occupied by the hardware, limiting its potential for other purposes. Although these points appear valid, it is worth considering that incorporating this technology may not have significantly increased the cost for each phone. Furthermore, for users who utilized the IR blaster function, it proved to be highly advantageous.
While mainstream Samsung or Apple phones do not come with an IR blaster, certain modern phone brands still offer this feature. This is particularly true for phones designed for the Chinese market. The Redmi Note 12, for instance, is a 2022 phone that incorporates various attractive features, such as an IR blaster and a 3.5mm headphone jack.

IR Blasters Would Still Be Useful Today
The absence of IR blasters in popular smartphones, including flagship models, wouldn't be as bothersome if it weren't for the ubiquitous presence of appliances that continue to rely on IR remote controls. These appliances not only enjoy a longer lifespan compared to personal devices like smartphones, but even newly released devices such as TVs and home theater systems still incorporate IR receivers.
IR Blaster Mischief Was the Best
An instantly-programmable universal remote is not only useful for controlling your own home appliances in emergencies, but it also comes in handy when you encounter a hotel room with a missing air conditioner or TV remote.
The practical advantages of retaining IR blasters are evident, but I must confess something. One of the main reasons I miss this feature on my current smartphones is the ability to play harmless pranks.
I have utilized IR blasters to manipulate TV channels and volume, adjust the temperature on boardroom thermostats, and switch the channels in restaurants to something more captivating. Possessing an IR blaster made me feel like a hacker, without the need for a device like Flipper Zero. Now, you'll have to settle for engaging in such mischief using Bluetooth, NFC, or wireless casting. Additionally, coming up with amusing names for your Wi-Fi network never loses its charm.
