Yes. CMOS image sensors are naturally sensitive to near IR. Early feature phones had no IR filters on their cameras - you could see an IR remote light up through them. But as people became more and more obsessed with smartphone camera quality, smartphones started to ship with those filters too. You get more "lifelike" colors that way. Although in some multi-camera smartphones, one of the secondary cameras may lack an IR filter. | ||||||||

One of mine definitely lacks such a filter because I was able to catch not only the remote, but also an electric stovetop while it was still heating up and its glow was barely visible with the naked eye. | ||||||||
