We've been getting a number of questions from readers about a mysterious "patch" on the edge of all of the iPhone 12 models introduced today. The patch is unlabeled on Apple's specs page, but The Verge has confirmed that it is a window for the mmWave 5G antenna.

mmWave 5G support is only included on U.S. models of the iPhone 12 lineup, and thus the window is only present on those devices, as seen in images shared on Apple's pages for various countries.

The mystery patch was first seen in leaked schematics dating back many months, and was initially speculated to potentially be a Smart Connector or docking site for a small Apple Pencil, given its similar appearance to the magnetic Apple Pencil attachment site on iPad Pro models. That speculation was, however, quickly dispelled as new rumors indicated it was for a 5G antenna.

I think you forgot about the overreaction of the iPhone 4 Antennagate event.

It most definitely was not an overraction on the iPhone 4. Just holding my launch day iPhone 4 like normal and I would drop calls or my internet speed would slow down to less than dial up. As soon as I added in the free bumper case that Apple provided all those issues went away.

mmWave is a gimmick in my book, and I have no intention of switching to Verizon. I have to have that “patch” on my phone either way since I’m in the US? That’s lame.

Plenty of people did not use a bumper and had no issues. Also issue was not specific to iPhones as many phones did the same thing when gripping in a specific way. Everyone I knew that did not use a case with their iPhone had 0 issues (same with me).

Completely overblown. If it was so bad, everyone would have returned the phone.

Actually was not an overreaction. Signal attenuation is real and the iPhone 4 did not have dual antennas for the affected bands. You could actually cause your call to drop so will this behave the same since it appears there’s only one mmWave antenna (assumes calls are routed over mmWave)?

Complete overreaction. Majority of customers did not return their phones and people who used the iPhone without case or bumper had no real issues.

Deliberately gripping in that area of course caused signal to drop, but most didn't encounter that issue on a practical day-to-day use. And iPhone wasn't the only phone that had that problem, yet they received 0 attention. Overreaction.
