This is why Apple seems to be exploring the idea of maybe one day introducing an iPhone that has the ability to clean itself. This is based on a patent discovered by AppleInsider where they found that Apple is suggesting a system that could help clean the sensors of a device by using ultraviolet light.
According to the patent’s description in part, it reads, “The UV light rays can initiate a photo-oxidation process, which results in decomposition of squalene. Upon reaction with UV light, squalene, shown with its chemical formula, is decomposed into three byproducts… that may not be hazardous to environmental sensors.”
It sounds like quite a complicated setup and we’re not sure if it is particularly realistic or necessary. However, given the coronavirus pandemic which has really opened our eyes even wider to the need for proper hygiene and sanitization, perhaps it’s not a bad idea. Whether or not it will actually be implemented is anyone’s guess.
