How to Fix 'Screen Timeout Not Working' on Android: Complete Guide
TL;DR: If your Android screen timeout isn’t working, check for features like Screen Attention, Developer Options, or third-party apps interfering. Common fixes include toggling settings, restarting your launcher, updating apps, or performing a cache partition wipe. For persistent issues, boot in Safe Mode to isolate app conflicts.
I’ve been there—frustrated because my Android phone’s screen just won’t turn off, no matter what timeout I set. It’s a common issue, but thankfully, it’s usually fixable. In this guide, I’ll walk you through the most effective solutions, step by step, drawing from real user experiences and technical insights.
Why Does Screen Timeout Stop Working?
Screen timeout issues can stem from various sources: software glitches, conflicting settings, or even hardware problems. Often, it’s a misconfigured feature or an app holding the screen awake. For instance, some users found that Nova Launcher had an option to stop and restart, which resolved the issue^1. Others reported that car mode apps or Smart Stay features were the culprits^2. Understanding the root cause is the first step toward a fix.
Check These Settings First
Before diving into complex troubleshooting, start with these basic checks:
- Screen Timeout Setting: Go to Settings > Display > Screen timeout and ensure it’s set to your desired duration (e.g., 15 seconds, 1 minute).
- Screen Attention: On Pixel and some Samsung devices, Settings > Display > Screen timeout > Screen Attention might be enabled, keeping the screen on if it detects your face^4. Disable it if unnecessary.
- Developer Options: If enabled, Stay awake while charging in Developer Options can override timeout. Disable it via Settings > Developer options.
Step-by-Step Fixes for Screen Timeout Issues
1. Restart Your Device
A simple reboot can resolve temporary glitches. Hold the power button, tap Restart, and check if timeout works afterward.
2. Toggle Screen Timeout Setting
Sometimes, resetting the setting helps:
- Go to Settings > Display > Screen timeout.
- Change it to a different value, wait a few seconds, then revert.
3. Check for App Conflicts
Third-party apps, especially launchers or accessibility tools, can interfere:
- Restart your launcher: For Nova Launcher users, try its restart option^1.
- Update apps: Outdated apps may cause conflicts. Update all apps via Play Store.
- Boot in Safe Mode: Hold the power button, then long-press Power off to enter Safe Mode. If timeout works here, an app is causing the issue.
4. Inspect Smart Features
Features like Smart Stay (Samsung) or Screen Attention (Pixel) use sensors to keep the screen on:
- Disable them via Settings > Advanced features > Smart Stay or Display > Screen Attention.
5. Clear Cache Partition
A corrupted cache can cause system issues:
- Power off your device.
- Hold Volume Up + Power buttons to enter recovery mode.
- Use volume keys to select Wipe cache partition and confirm.
- Reboot and test timeout.
6. Check Accessibility Settings
Some accessibility services prevent screen timeout:
- Go to Settings > Accessibility > Installed services.
- Disable any recently enabled services and test.
7. Update Software
Outdated OS versions may have bugs:
- Navigate to Settings > Software update > Download and install.
8. Reset App Preferences
This resets app permissions without deleting data:
- Go to Settings > Apps > More options (three dots) > Reset app preferences.
When Screen Timeout is Grayed Out
If the timeout setting is unavailable, it’s often due to security policies or other settings:
- Device Admin Apps: Go to Settings > Security > Device admin apps and disable any unnecessary ones.
- Secure Lock Settings: On Samsung devices, Secure settings > Auto lock when screen turns off might be set to a high value, graying out timeout^3. Adjust it.
- Work Profile: If using a work profile, contact your IT admin for policy changes.

Remember, most timeout issues are software-related and fixable without drastic measures. If you’ve tried everything and still face problems, it might be time to consult professional support or consider a warranty claim[^9][^10].
My Step-by-Step Troubleshooting Process
When my screen timeout acts up, I follow a structured approach to isolate the cause without getting overwhelmed. Here’s my personal step-by-step method:
- Restart the device: It sounds basic, but a reboot often clears temporary glitches affecting system settings[^8].
- Verify timeout setting: I go to Settings > Display > Screen timeout and confirm it’s set correctly—sometimes it gets reset by updates or apps.
- Check for interfering features: I disable Screen attention or Smart stay if enabled, as these can prevent the screen from turning off^4.
- Review Device Admin apps: I navigate to Settings > Security > Device admin apps and ensure no app is enforcing its own timeout policy^3.
- Test in Safe Mode: Booting into Safe Mode helps me determine if a third-party app is the culprit. If timeout works normally there, I uninstall recently added apps one by one.
- Clear cache partition: For persistent issues, I wipe the cache partition from recovery mode—this doesn’t delete personal data but can resolve system-level bugs.
- Update software: I check for OS and app updates, as fixes for timeout bugs are often included in patches[^2][^9].
Pros and Cons of Common Fixes
- Native Settings Adjustment:
- Pros: Safe, battery-efficient, and reversible.

- Developer Options:
- Pros: Offers "Stay awake while charging" for hands-free use during tasks like navigation or presentations^5.
- Cons: Can drain battery quickly if left enabled; may introduce instability if other developer settings are altered.
- Third-Party Apps:
- Pros: Provide granular control, such as custom timeout per app or scenario.
- Cons: Risk of conflicts with system settings; some require accessibility permissions that could impact performance.
- Factory Reset:
- Pros: Resolves deep-seated software issues by restoring default settings.
- Cons: Time-consuming; requires backing up data; should be a last resort[^10].
Through this process, I’ve successfully resolved timeout issues on multiple devices, though patience is key—rushing can lead to unnecessary resets or missed solutions.
