How to Resolve vivo X300 Pro Always On Display Not Working

If the Always On Display on your vivo X300 Pro is not showing, the lock screen may stay completely dark when the phone is idle. This can make it harder to check the time or notifications quickly without waking the device.

The issue usually comes from simple settings, battery restrictions, or a display schedule that limits when the feature appears. A few quick checks can usually restore Always On Display.

Why the vivo X300 Pro Always On Display Is Not Working

• Always On Display is turned off in the display settings.
• Battery Saver mode is limiting background display features.
• The AOD schedule is set to specific hours only.
• Notifications are disabled for the lock screen display.
• A temporary software glitch is preventing the feature from activating.

Make Sure Always On Display Is Enabled

Always On Display must be turned on manually in the display settings. If it is disabled, the screen will stay black when the phone is locked.

1. Open Settings, and then tap Lock screen and wallpaper.
2. Tap Always On Display, and then toggle the feature on.

Lock the phone and wait a few seconds. The clock or AOD style should appear on the screen.

Disable Battery Saver Mode

Battery Saver limits certain visual features to extend battery life. This sometimes disables Always On Display automatically.

1. Open Settings, and then tap Battery.
2. Tap Battery Saver, and then turn it off.

After disabling it, lock the device and check if the Always On Display appears.

Check the Always On Display Schedule

Some users enable a schedule so the display only appears during certain hours. If the current time is outside that range, AOD will not activate.

1. Open Settings, and then tap Lock screen and wallpaper.
2. Tap Always On Display, and then tap Schedule.

If scheduling is enabled, adjust the time range or disable the schedule entirely.

Restart the Phone

A simple restart refreshes system services that control display behavior. It is a quick way to clear temporary glitches.

1. Press and hold the Power button, and then tap Restart.
2. Wait for the phone to reboot, and then lock the screen to test AOD.

This often restores features that stopped working after updates or background errors.

Reset Display Settings

If none of the previous steps work, a display configuration may be causing a conflict. Resetting display settings restores the default configuration without deleting your data.

1. Open Settings, and then tap Display and brightness.
2. Tap Reset display settings, and then confirm the reset.

Once completed, enable Always On Display again and test the lock screen.

Always On Display is designed to work automatically on the vivo X300 Pro. After checking the settings and removing battery restrictions, the feature should return to normal and show the time and notifications whenever the screen is locked.
