Set Date & Time Automatically auf Huawei
Huawei phones running EMUI pull the current time, date and time zone from the mobile network by default. This works reliably as long as the signal is stable and the carrier sends correct network time data. Weak reception, a foreign SIM card, or a locked network connection can cause the displayed time to drift or the time zone to stay stuck on the wrong region.
To set the values yourself, you first need to switch off the automatic sync. Once disabled, you can enter a specific date and time manually, which is useful when the network signal is unreliable or when you want a fixed time regardless of location changes.
Menu path
Open the settings ➔ Tap on System & updates ➔ Tap on Date & time ➔ Activate or deactivate Set automatically ➔ Tap on Date or Time to set date or time yourself
If you later reconnect to a stable network and want the phone to sync again, just turn Set automatically back on. The device will then overwrite any manual values with the network-provided time.
