Lock screen notifications are important. They let you see messages, calls, and alerts without unlocking your phone. If they suddenly stop appearing on your vivo X300 Pro, it can make you miss important updates.
This issue is often caused by notification restrictions, display settings, or power-saving features. Fortunately, it’s easy to fix once you know where to look.
Why Your vivo X300 Pro Lock Screen Notifications Might Not Be Showing
- Lock screen notifications are disabled in settings.
- App notification permissions are restricted.
- Power saving or background limits are blocking notifications.
- Do Not Disturb mode is turned on.
- System software bugs or outdated firmware.
Enable Lock Screen Notifications.
Lock screen notifications may have been disabled. Turning them back on ensures you see alerts even when your phone is locked.
- Open Settings, and then tap Notifications and status bar.
- Tap Manage notifications, and then toggle on Lock screen notifications.
This allows messages and alerts to appear as banners or icons when the screen is off.
Allow Notifications for Specific Apps.
Even if system notifications are on, individual app settings may still block alerts. Checking them ensures all important apps can display messages.
- Open Settings, and then tap Notifications and status bar.
- Tap Manage notifications, and then select the app that is not showing notifications.
Toggle on Allow notifications, and then make sure Lock screen notifications are enabled for that app.
Check Lock Screen Display Style.
vivo phones allow you to customize how notifications appear on the lock screen. You may have chosen a style that hides details.
- Open Settings, and then tap Lock screen, home screen, and wallpaper.
- Tap Lock screen settings, and then choose Show notification content.
If you prefer privacy, you can choose Show notifications but hide content.
Turn Off Do Not Disturb.
Do Not Disturb mode blocks alerts, vibrations, and lock screen notifications. Disabling it ensures you receive all messages again.
- Open Settings, and then tap Sound and vibration.
- Tap Do Not Disturb, and then toggle it off.
Once disabled, try sending yourself a message to confirm notifications appear again.
Disable Battery Optimization for Apps.
Battery optimization can prevent apps from showing notifications while the phone is idle. Turning it off for key apps ensures they continue to alert you.
- Open Settings, and then tap Battery.
- Tap Battery optimization, and then select the app you want to exclude.
Choose Don’t optimize to let the app send notifications freely.
Update System Software.
An outdated version of Funtouch OS may cause notification bugs. Updating the system can restore normal notification behavior.
- Open Settings, and then tap System update.
- Tap Check for updates, and then install if available.
Restart your phone after updating to apply all fixes.
Lock screen notifications help you stay aware of important alerts without unlocking your phone. Once these steps are done, your vivo X300 Pro should display messages and app notifications properly again.
