Selling a smartphone on Android requires careful preparation of the device - especially when it comes to deleting linked accounts. Many users encounter problems after transferring a gadget to a new owner: from blocking FRP (Factory Reset Protection) to leaks of personal data from cloud services. This article will help you avoid common mistakes and properly clean your phone before selling it.

Just performing a factory reset is not enough! Even after hard reset traces of your accounts may remain on the device if they are not deleted in advance through the settings. This is especially true for accounts Google, Samsung, Mi Account (Xiaomi) and other manufacturers. In this instruction, we will look at how to completely unlink all profiles while maintaining access to your data on new devices.

The process of deleting accounts depends on the version Android and brand of the smartphone. For example, on Samsung Galaxy s One UI the path to account settings differs from pure Android on Pixel or Xiaomi with shell MIUI. We will look at universal methods and features of popular brands.

Why you can’t just reset the settings

Many users mistakenly believe that resetting to factory settings (Factory Data Reset) completely erases all data from the phone. In fact, this is not so:

  • ☁️ Data from cloud services (photos, contacts, notes) can be automatically downloaded to the device after a reset, if the account has not been unlinked.
  • 📱 Manufacturers (for example, Samsung or Xiaomi) bind additional services to the device that are not deleted during a standard reset.

Moreover, on some models (for example, Huawei c EMUI) after a reset you may need to enter password from the previous account Huawei ID, even if the phone has already been transferred to the new owner. This makes the device virtually unusable without your help.

⚠️ Attention: If you sell a phone with corporate profile installed (for example, through Android Enterprise or Samsung Knox), it must be removed through the IT administrator. Self-deletion may block the device.
