The address book on a smartphone is not just a list of phone numbers, but a real database that is synchronized with accounts, instant messengers and cloud services. Many users encounter the problem: where exactly is this information stored on the device? The question arises especially acutely when you need to transfer contacts to a new phone, restore deleted entries, or simply understand how the storage system works.

On Android the address book can be in several places at the same time - it all depends on the version of the operating system, the smartphone manufacturer (Samsung, Xiaomi, Google Pixel etc.) and synchronization settings. In this article we will analyze all possible options: from the standard application "Contacts" to hidden system folders and cloud services. You will also learn how to find backups and what to do if your contacts suddenly disappeared.

⚠️ Attention: If you are using a smartphone with custom firmware (for example, LineageOS or MIUI with root access), the location of the address book files may differ. In this case, check the synchronization settings manually or use specialized applications to manage contacts.
