Following the announcement that Apple (AAPL Quick QuoteAAPL - Free Report) removed the standard 3.5mm headphone jack from the iPhone 7 and 7 Plus, people mercilessly ridiculed the company and its new line of phones—and that was before it was even released. Now that users have finally gotten their hands on the iPhone 7, new criticism is coming as a result of several different functionality problems.

The main issue seems to revolve around an unusual hissing or buzzing noise coming from the phone while using processor-intensive applications. The problem has been dubbed “Hissgate,” and it’s currently making its rounds on Twitter.

It is currently unknown how many devices are affected by the hissing noise, and Apple has yet to comment on the problem.

Other iPhone 7 owners are complaining about issues that they are having with the Apple’s new EarPods:
