The iPhone 7 is expected to be a pretty boring upgrade, at least on the outside. But a new report reveals a few minor external changes that could still be coming to Apple’s next smartphone.

Japanese site Macotakara claims that the iPhone 7 will feature a larger earpiece and a relocated ambient light sensor. The device could also include a new and more accurate proximity sensor. The report cites several firms that make or sell iPhone screen protectors and say they’ve stopped receiving orders due to these minor changes.

That means some cases and accessories for the iPhone 6 may not work with the iPhone 7, even if the two phones look pretty similar. Anything that covers the front of the device will likely have to be redesigned to match up with the new light sensor location and the bigger earpiece.

The iPhone 7 is also expected to lose the traditional headphone jack, forcing you to use Apple’s Lightning port or a Bluetooth connection instead. The iPhone 7 Plus could feature a dual rear camera as well, though recent reports suggest Apple may actually scrap that feature.

Like we said, the iPhone 7 probably won’t be a huge change from last year’s model. But it may still be a worthy update if Apple can squeeze in enough small changes.
