The new iPhone 7 models were released last week and the demand is reportedly so high that there's a shortage of all iPhone 7 Plus and jet black models.

However, some early adopters who managed to secure Apple's newest handsets are reporting issues that may be affecting more than a handful of units.

Hissing under load

The first issue reported was a strange hissing sound originating from the back of some iPhones, especially when under heavy processing load.

Stephen Hackett of Relay FM tweeted the issue on Saturday stating that his iPhone 7 "makes terrible noises when under load." As demonstrated by his accompanying audio clip (posted below), the hissing sound is said to be quite audible.

TechCrunch's Darrell Etherington replied to the tweet saying that his "brand new, just-unboxed" iPhone 7 was "doing the same thing."

According to the MacRumors forums, other iPhone 7 owners are confirming the hissing-under-load issue and were advised by AppleCare to bring the affected handsets to their respective Apple Store for replacement. The problem is that some of the iPhone 7 replacement handsets are exhibiting the same hissing issue.

It's unclear at this point if the noise is a general issue of all iPhone 7 models or if it is just a problem with defective batches.

The general theory going around now, as noted by this article from The Verge, is that this could be "coil noise," the sound an electronic part normally makes especially if it's not properly dampened. Although the phenomenon is commonly associated with desktop computer components, the iPhone 7's A10 processor is powerful enough to elicit worse coil noise than previous models.

Like most computers, there is apparently no fix for a hissing-under-load iPhone 7. If you hear anything of this sort and you can't stand the noise, it is recommended that you bring it to the Apple Store for a replacement.

No Service after Airplane Mode

Another iPhone 7 issue that emerged during the weekend is the loss of cellular service after switching from Airplane Mode back to its regular signal.

As demonstrated in the video below, an iPhone 7 is shown to lose its LTE signal after toggling Airplane Mode.

MacRumors says that Apple is investigating the issue and is advising service providers to tell iPhone 7 customers to restart their handsets if they encounter the issue. If the problem persists even after a restart, Apple advises to remove and re-insert the SIM card.

As with the hissing noise issue, if you're getting a persistent "No Service" notice after turning off Airplane Mode, you can visit your nearest Apple Store for a replacement iPhone 7.
