Half of the screen is on with time display while the other half is off

Problem:

The phone occasionally displays time on half of the screen while displays the other half in black.

Cause:

Your phone may have entered Smart cover mode.

Once enabled, Smart cover will be triggered when the Hall effect sensor detects that your phone's flip cover is closed. Your phone will then display the date and time on one half of the screen and turn off the other half. This issue may happen when there are magnetic objects (such as a speaker) or strong magnetic fields nearby (such as from an electromagnetic oven, microwave oven, or wireless charging base). (This issue will not occur in phones without a Hall effect sensor.)

Solution:

1. Keep your phone away from magnetic objects or strong magnetic fields (such as from an electromagnetic oven, microwave oven, or wireless charging base).
2. You can also open Settings, search for and assess Smart cover, then disable Smart cover.

3. If the issue remains unresolved, take your phone and proof of purchase to an authorized Huawei Customer Service Center for assistance.

Smart cover mode works based on the Hall effect sensor, which determines whether the flip cover is closed by sensing the magnetic field of the magnet on the cover.
