Why does Huawei always enter the Harmony os interface when the mobile phone is turned on?

If your mobile phone is turned on and enters HarmonyOS system interface, EMUI interface and FASTBOOT interface, it may be caused by the following reasons:

(1) You may have accidentally pressed the combination of the power button and the volume button to enter the special mode. It is recommended that you press and hold the power button 15 seconds or more, and try to forcibly restart the mobile phone and enter the mobile phone desktop normally.

Warm reminder: Mate40 series and MateX2 phones are forced to restart their phones by holding down the volume down button and the power button for more than 10 second.

(2) In order to avoid this situation in the future, I suggest you check whether the key is easy to get stuck or the protective sleeve you are wearing squeezes the key.

(3) If the above methods can't be solved, please bring the relevant purchase voucher to the nearby Huawei customer service center for maintenance.

Warm reminder: If you have not backed up your data before, you may lose your data during maintenance.
