The coronavirus affecting Apple's overseas operations has caused a shortage of iPhone replacements, the company warned retail store employees.

According to Bloomberg, Apple store employees said that technical associates (aka Geniuses) were advised that replacements for damaged iPhones would be sparse for up to four weeks. A note sent to them suggested that, amidst the delays, they would be provided with a replacement unit until the replacement order could be completed by mail.

When a device is brought to the Genius bar and deemed unrepairable, Apple typically provides a refurbished replacement iPhone rather than offering a new model right out of the box.

However, the company often attempts to replace individual parts. For example, if the screen is cracked or one of the volume buttons is broken, there is no need to purchase an entirely new iPhone.

However, Apple employees told Bloomberg that these individual parts are also in low stock and that they are feeling the effects of shortages in stores.

The coronavirus has hit Apple particularly hard in recent weeks. However, the situation is showing signs of improvement. As of this writing, nearly all Apple store outlets in China have reopened, and the factory that manufactures the iPhone 9 is back at work.

It is too early to say whether the iPhone 9 launch is on schedule. We previously thought Apple planned to launch the budget iPhone at the end of this month.
