If your vivo S50 screen refuses to turn off, the display may stay on longer than expected or never sleep at all. This can drain your battery quickly and make the phone feel unreliable. The problem usually comes from display settings, system permissions, or apps that keep the screen awake, and you can fix it with a few targeted checks.
Why Your vivo S50 Screen Timeout Is Not Working
- Screen timeout is set to a very long duration or never option.
- Battery saver or smart features are overriding display behavior.
- Certain apps are preventing the screen from sleeping.
- Accessibility or developer options are keeping the screen active.
- Temporary system glitches affecting display controls.
1. Check the Screen Timeout Setting
Screen timeout controls how long the display stays on when the phone is idle. If it is set too long, it can feel like the feature is not working at all.
Open Settings, and then tap Display and brightness.
Tap Screen timeout, and then select a shorter time like 30 seconds or 1 minute.
2. Turn Off Smart Screen Features
Some vivo devices keep the screen on when they detect movement or your face. These features can override the normal timeout setting.
Open Settings, and then tap Display and brightness.
Tap Smart screen or similar options, and then turn them off.
3. Disable Battery Saver Restrictions
Battery saving features sometimes interfere with how the screen behaves. This can cause delays or prevent the screen from turning off properly.
Open Settings, and then tap Battery.
Tap Battery saver, and then turn it off temporarily to test screen timeout.
4. Check Apps Keeping the Screen Awake
Certain apps like video players, navigation apps, or games can stop the screen from sleeping. If one of these runs in the background, screen timeout may fail.
Open Settings, and then tap Apps.
Tap App management, and then review recently used apps and close any suspicious ones.
5. Turn Off Accessibility Services
Accessibility features are designed to keep the screen active for easier interaction. If enabled, they can override screen timeout.
Open Settings, and then tap Accessibility.
Tap installed services, and then disable any features you do not actively use.
6. Restart the Phone
A restart refreshes system processes that control the display. This often fixes temporary bugs that affect screen timeout.
Swipe down from the top of the screen, and then tap the Power icon.
Tap Restart, and then wait for the device to boot fully.
7. Reset Display Settings
If the issue persists, resetting display settings can remove hidden conflicts. This restores default behavior without deleting your data.
Open Settings, and then tap System management.
Tap Reset options, and then reset display or system preferences if available.
Once screen timeout starts working again, your vivo S50 should behave normally and conserve battery more efficiently. Keeping display and battery settings balanced helps prevent the issue from returning.
FAQs
Why does my vivo S50 screen stay on while charging?
Some phones keep the screen awake when charging, especially if a setting or app allows it. Check display and battery options to disable this behavior.
Can apps really stop screen timeout from working?
Yes. Apps that play media, use navigation, or require constant interaction can keep the screen awake until they are closed.
Does screen timeout affect battery life?
Yes. A shorter screen timeout helps save battery by turning the display off sooner when the phone is not in use.
