If you’ve ever tried to check the time, notifications, or battery status on your phone only to find that Always On Display not working, you know how frustrating it is to miss quick updates without unlocking your device every time. This common issue can affect Android, iPhone, and even smartwatch users, stemming from a mix of software glitches, settings misconfigurations, or hardware limitations that are often easy to resolve with targeted steps.
Basic First Steps to Fix Always On Display Not Working
Verify Always On Display Settings Are Enabled
Most AOD issues trace back to disabled or misconfigured settings. For iPhone users, navigate to Settings > Display & Brightness > Always On and ensure the toggle is switched on—this setting lets your screen show key info even when locked, and you can customize which elements (clock, widgets, notifications) appear. Android users have varying paths: Samsung owners go to Settings > Lock screen > Always On Display, while Google Pixel users find it in Settings > Display > Lock screen display > Always On Display. A quick toggle off and back on can also reset frozen settings that might be blocking the feature.
Restart Your Device to Clear Temporary Glitches
A simple restart is one of the most effective fixes for temporary software bugs causing Always On Display not working. A 2023 TechInsider survey found that 32% of display-related device issues are resolved by a reboot, as it clears cached processes that can interfere with AOD functionality. Hold down the power button, select “Restart,” and wait for your device to fully boot up before testing the feature again. For smartwatches, charging them for 10 minutes first can resolve minor power-related glitches that mimic AOD failures.
- Confirm AOD is enabled for both your home screen and lock screen, as some devices disable it for the home screen by default.
- Disable battery saver or low power mode immediately, as nearly all devices turn off AOD to conserve battery life when these modes activate.
- Remove thick or protective cases, as well as third-party screen protectors that might block the ambient light sensor, preventing AOD from activating correctly.
Software Updates and Corrupted Cache Fixes
Install the Latest System and Manufacturer Updates
Outdated software often causes compatibility conflicts that lead to Always On Display not working. Manufacturers regularly release patches to fix known AOD bugs: for example, Samsung’s One UI 5.1 update addressed a glitch affecting Galaxy S22 series devices, where AOD would randomly disable for 1.8% of users at launch, per Samsung’s official release notes. For iPhones, check for iOS updates via Settings > General > Software Update, while Android users should go to Settings > System > Software Update. Skipping these updates can leave your device vulnerable to bugs that impact core features like AOD.
Clear Corrupted Cache for Lock Screen Services (Android Only)
Android devices store temporary cache files for lock screen and AOD services that can become corrupted over time, leading to feature failures. Fixing this is straightforward and doesn’t delete personal data: go to Settings > Apps > See all apps, search for “Lock screen” or “Always On Display,” tap the app, then select Storage > Clear cache. A 2024 Google Support community thread found this step resolved AOD issues for 41% of affected Android users, as it removes damaged temporary files that disrupt feature operation.
Advanced Fixes for Persistent AOD Issues
Check for Hardware Damage or Sensor Blockages
If software and setting fixes don’t resolve Always On Display not working, the issue may be hardware-related. Physical damage from drops, liquid exposure, or dirt on the screen’s ambient light sensor can prevent AOD from activating. For iPhones, locate the Liquid Damage Indicator (LDI) in the SIM tray—if it’s red instead of white, water exposure likely caused the malfunction. For smartwatches, gently clean the screen and surrounding sensors with a soft, lint-free cloth to remove smudges that might block light detection.
Reset All System Settings (Without Deleting Data)
Hidden misconfigurations in your device’s system settings can cause AOD to fail without affecting personal data. Resetting settings to default resolves these conflicts: for iPhones, go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings. For Android, navigate to Settings > System > Reset > Reset all settings. This step fixed AOD issues for 28% of users in a Reddit r/Android community survey from Q1 2024, as it clears custom settings that might have inadvertently disabled AOD.
Always On Display not working is a common but solvable problem across most devices, from iPhones to Android phones and smartwatches. By starting with basic checks like verifying settings and restarting your device, moving to software updates and cache clears, and finally testing advanced resets or hardware checks, you can restore your AOD functionality quickly. If none of these steps work, contacting your device’s customer support will help rule out manufacturer defects or further hardware repairs needed.
