Selling a smartphone on Android requires careful preparation, especially when it comes to deleting linked accounts. Many users encounter problems after transferring the device to a new owner: from blocking through Factory Reset Protection (FRP) to leakage of personal data. Why does this happen?
The fact is that simply deleting an account through settings or resetting to factory settings is not always enough. Some services (for example, Google or Samsung Knox) leave โtracesโ in the system, which can lead to the phone being blocked for a new user. Moreover, if you forgot to unlink your account Mi Account on Xiaomi or Huawei ID, the new owner will not be able to activate the device without your data.
In this article we will analyze all methods of completely deleting accounts taking into account the characteristics of different manufacturers, and also tell you how to avoid typical errors. We will pay special attention to hidden bindings that remain even after resetting the settings โthey are often overlooked.
1. Why is it not enough to just reset the phone to factory settings
Many believe that the function Factory reset in the settings menu completely cleans the device. In practice this does not always work. Here's why:
Manufacturers of Androiddevices (especially Samsung, Xiaomi, Huawei) integrate additional protection mechanisms into the firmware. For example, Factory Reset Protection (FRP) is a security feature from Googlethat requires you to enter the details of the last linked account after a reset. If you have not deleted your account Google in advance, the new owner will not be able to use the phone.
In addition, some brands (for example, Xiaomi) link the device to the manufacturer's account (Mi Account). Even after a reset, the system may request the original unlock data. This applies to both Huawei s Huawei IDand Samsung s Samsung Account.
โ ๏ธ Attention: On devices with Android 12 and newer the FRP mechanism has become stricter. If your phone was protected with a PIN code or pattern, you may be required to enter your account information after the reset, even if you deleted it. Always check this manually!
- ๐ FRP lock: Activated if you do not delete the account Google before resetting.
- ๐ฑ Manufacturer accounts: Mi Account, Huawei ID, Samsung Account can block the device.

Settings โ Security). - ๐ถ No Internet connection (account can only be deleted online).
- ๐ The device is in Demo or mode Kiosk (found on branded phones).
โ ๏ธ Attention: On some devices (for example, Google Pixel, after deleting your account, you may need to reboot. Do not skip this step - otherwise the FRP lock will remain active.

account.xiaomi.comfrom another device. - In the menu
