1. Fixing Random App Crashes & Freezing
If apps close automatically, it's usually a conflict between ColorOS RAM management and Google's WebView.
- Update WebView: Go to Play Store > Search "Android System WebView" > Update. This fixes 90% of app crash issues.
- RAM Expansion: Go to Settings > About Device > RAM. Set RAM Expansion to +2GB (not max). Setting it to max (+5GB) can sometimes slow down storage speed.
- App Cloner: If using cloned apps (Dual WhatsApp), try disabling and re-enabling. Corrupted clone data often causes crashes.
2. Solving Camera Blur & Microlens Issues
The F21s Pro has a unique 30x Microlens. Users often mistake it for a regular macro, resulting in blurry shots.
- Clean the Ring Light: The Orbit Light accumulates dust. Use a soft cloth to clean the circular ring around the microlens. Dust here confuses the sensor.
- Use Correct Mode: Only use "Microscope" mode when the object is literally touching the phone case. For regular close-ups, use standard photo mode.
- Reset Camera: Go to Camera Settings > Restore Defaults. This fixes issues where AI filters cause lag or blur.
3. Fixing Yellow/Warm Display Tint
AMOLED screens can sometimes look too warm or yellow out of the box due to eye protection settings.
- Eye Comfort Shield: Check if "Eye Comfort" is scheduled. Turn it OFF completely to see true whites.
- Screen Color Mode: Go to Settings > Display > Screen Color Mode. Switch from "Natural" to "Vivid" for punchy colors or adjust the slider to "Cooler".
- OSIE Visual Effect: Turn ON "OSIE Visual Effect" in display settings. It enhances video color and clarity on apps like TikTok/Instagram.
4. Preventing Overheating (Snapdragon 680)
The phone is slim, which affects heat dissipation. Here is how to keep it cool.
- High Performance Mode: Go to Battery Settings > Advanced > Turn OFF "High Performance Mode". It consumes too much power for daily tasks.
- Optimized Charging: Enable "Optimized Night Charging". This prevents the battery from heating up by overcharging while you sleep.
- Game Focus Mode: While gaming, use Game Toolkit to block background syncs, reducing CPU load and heat.
Additional Maintenance (Steps 13-15)
- Step 13 (Phone Manager): Use the "Optimize" button in Phone Manager daily. It clears cache and kills zombie processes.
- Step 14 (Animation Scale): Set Developer Options > Animation Scales to 0.5x for a faster feeling UI.
- Step 15 (Factory Reset): If the display tint persists, it might be a software bug. Backup and Reset System Settings (Not Data) first.
