Adjusting Display Settings

• 💡 Open Settings and navigate to Display & Brightness & Eye Protection.
• 🎯 Adjust the brightness level to your preference, with a recommended setting slightly above 50%.

Using a Screen Dimmer App

• 📱 If flickering persists, download the Screen Dimmer / OLED Saver app from the Google Play Store.
• ⚙️ Grant the app necessary permissions, including Modify System Settings and Overlay.
• 🛠️ Enable the app's service within Downloaded Services and allow sensitive permissions and notification access.
• ✅ Test the app's overlay by toggling the service on and off to compare the display.

System Updates as a Last Resort
