Cảnh báo “Phát hiện phụ kiện lạ” trên iPhone: Ý nghĩa và cách xử lý

While the “Unknown Accessory Detected” alert is supposed to be helpful, it might feel quite alarming. Especially if you’re traveling alone or are in a new city, country, etc. We suggest you do not panic and read along to understand what this alert means and what steps you can take to prevent anyone from tracking your location. 

What Does It Mean When I Get an “Unknown Accessory Detected” Alert?

Suppose you get an “Unknown Accessory Detected” alert on your iPhone. In that case, a device compatible with Apple’s Find My network is travelling with you, and the product’s owner can view its location. The purpose of the alert is to inform you that an unknown device – one that doesn’t belong to you – can convey your location to someone else.

The “Unknown Accessory Detected” alert is only displayed when a pair of AirPods or an accessory compatible with the Find My network is detected near you. If an AirTag is tracking you, there’s a different alert for it. Moreover, the reason the alert states “Unknown Accessory” is that the Find My app has issues connecting to the device or server and cannot identify the product. 

You need not panic the moment you see this alert. Because, there are chances that a friend or a family member has mistakenly left behind their AirPods, etc. However, it can be someone trying to deliberately track you too. Regardless, we will help you find this Unknown Accessory further in this guide. 

Which Devices Can Send Alerts?

The below listed Apple products are responsible for the location tracking alerts on your iPhone, iPod, or iPad 

• AirPods (3rd Gen)
• AirPods Pro 
• AirPods Max
• AirTags

Apart from these Apple products, some other third-party products support Apple’s Find My network. Some of the first products to support the Find My network are, VanMoof S3 and X3 e-bikes, Belkin SOUNDFORM Freedom True Wireless Earbuds, and Chipolo ONE Spot item finder. 

These products don’t send the same “Unknown Accessory Detected” alert. Let’s have a look at the different alerts for various Find My products and what they mean. 

1. AirTag Found Moving With You: This alert is displayed when an AirTag belonging to someone else moves with you over time. Or, if an AirTag belonging to someone else emits a sound to notify that it has moved, you will see this alert. 

2. AirPods Detected, AirPods Pro Detected, AirPods Max Detected: You will see one of these alerts when any of these products have been separated from their owner and are moving with you over time. 

3. “Product Name” Found Moving With You: You will see this alert when a Find My network accessory separated from its owner is moving with you over time. Also, “Product Name” is just a placeholder for the product’s actual name. 

As mentioned, the “Unknown Accessory Detected” alert is only displayed when Find My app has issues connecting to a device or the server. Also, apart from notifications, some of these products emit a sound when they’re separated from their owner and are moving over time. 

How To Prevent Unwanted Tracking by Enabling Alerts

Many people misuse AirTags and other Find My Network accessories. Therefore, Apple has implemented a system to prevent the misuse of the Find My network and discourage people from tracking others without their knowledge. Here, if a device separated from its owner is moving with you over a certain period, you will be informed about it. 

This Notification tracking feature is available on devices running on iOS and iPadOS 14.5 and above. Read along to learn how to enable device tracking alerts to receive notifications of unknown Find My network-enabled devices tracking your location without your consent.
