If your device is displaying the wrong local time even though the time zone is set to "USA" or "China," please follow the steps below to manually correct it.
Solution 1: Manually Set Home Time Zone
On the home screen, click the time display to enter the "Clock Settings" page.
Tap the three dots (⋮) in the top-right corner and select "More Settings."
Scroll down to "Home Time zone" and manually select your current city/region.
Return to the home screen to check if the time is now correct.
Solution 2: Enable Automatic Time Update (Recommended)
If you prefer automatic time synchronization:
Go to Settings > System > Date & Time.
Turn on "GPS automatic update time" (or "Automatic date & time").
This should resolve the time zone issue. If the problem persists, please try restarting your device.
