Synchronizing phone data can be useful, but it also poses a security risk if linked with someone else's device. Signs of unapproved linking include increased data usage and performance issues on both phones. You can check for this by reviewing your settings and Bluetooth connections; running malware scans to look out for suspicious software will also be effective ways of finding any potential issues.
1. Go to Settings
Device syncing can be an extremely convenient feature, yet also poses a potential security threat. If two devices are synced together, it becomes possible for any of them to access your personal information such as photos, apps and browser tabs without your knowledge - potentially installing hidden applications and changing phone settings without your knowledge.
To identify whether or not your phone is linked with another device, head into its Settings and search for unfamiliar devices. You can also keep an eye on app permission requests to see if any are seeking access from other devices. Moreover, running a malware scan may help detect and eliminate threats linked to your phone.
Digital Wellbeing or Screen Time can also help keep an eye on app usage and activity on Android or iOS devices, including notifying you if synchronized notifications or activity occurs that wasn't initiated by yourself - it could indicate your phone being linked with another device.
2. Go to Bluetooth
Bluetooth is an inexpensive, short-range radio communications technology that connects your phone to other devices. When two Bluetooth-enabled phones within range of each other are in proximity, they can pair and start exchanging data copies securely - each device has a unique ID number which requires approval by another phone (usually 0000 or 1234).
Warning signs that your phone might be connected to another device include unexpectedly high data usage and battery drain, which you can check by opening your Bluetooth settings and looking for a list or section that displays previously connected devices.
Unauthorized device syncing can expose sensitive information to attackers and incur unexpected wireless bill charges. Bluetooth connection also offers hackers a means of transmitting unwanted text messages or even spreading viruses and malware.
3. Go to Devices
Linking devices allows third parties to gain access to your personal data and messages, as well as control certain functions on your phone. They pose a security threat; if you notice increased data transfers, rapid battery drain, or slower performance this could be a telltale sign that your phone has become linked with another device.

If a device is connected to your phone, there will be an option to either add or unlink it from Sync chain. Select Add This Device if you would like the new mobile or desktop device added and scan a QR code or enter word code to complete linking process. To protect against malicious software connecting with devices without your knowledge or install a reliable anti-malware app and run full malware scan regularly as well as regularly reviewing Sync page for suspicious devices or activities.
4. Go to Unsync
Device syncing can be an efficient way of sharing data across devices, but it also presents a security threat if someone gains access to your phone. From confidential business files to embarrassing selfies, your information could be on display and stolen by hackers; knowing how to check if your phone is synced to another device allows you to protect yourself effectively.
One effective way to check for sync issues on your device is by accessing its settings or account section. Here, you will usually be provided with a list of accounts currently linked with it; simply log out from them on both devices to prevent further sync between devices.
This method may prove especially useful if your phone has been stolen, as it will cut all connections with any other devices associated with your account information. However, doing so could wreak havoc for other services or apps that depend on these accounts for functionality - so think carefully before proceeding.
