IR blaster on a smartphone allows you to control any device around you that can be controlled using a remote. This means that on a phone with an IR blaster, you can control the TVs, ACs, music systems and other such devices around you.
Want a confirmation? Have a look at the image below.
The hole at the far left is for the microphone, while the hole nearest in the picture is for the microSD and nanoSIM card slots.
Samsung had removed the IR blaster on the Galaxy Note 5 and Galaxy S6 edge+ last year itself, so its omission on the Galaxy S7 and S7 edge should not really be surprising.
The Korean company did not announce why it has removed the IR blasters — despite its usefulness — from its latest flagship Galaxy devices, but my theory is that the company noticed that not many consumers were using it. Sure, power users love having an IR blaster on their device, but the average joe out there has likely never used this feature on their phone.
Thus, Samsung decided it would be wise to drop this feature from their flagship phones for 2016 and reduce its BOM (bills of materials) slightly.
Oh, and if a phone with an IR blaster is an absolute must for you, have a look at the LG G5.
