How to Fix Auto Brightness Not Working on VIVO Y19s

Troubleshooting Auto Brightness on VIVO Y19s

• 💡 Auto brightness on your VIVO Y19s might not be enabled. Check the control center for the 'A' icon next to the brightness bar; if it's grayed out, tap it to enable automatic brightness.
• ⚡ When enabled, auto brightness adjusts screen luminosity based on ambient light levels detected by the phone's sensors.

Rebooting and Sensor Reset

• ⚠️ If auto brightness is enabled but not functioning correctly, a reboot of your device is recommended.
• 🧠 This process restarts the sensors responsible for detecting light levels, which can resolve temporary glitches.

Display Settings and Brightness Perception

• 🔍 Within settings, navigate to 'Display & Brightness' to check for other features that might affect brightness perception.
• 👁️ Eye Protection mode, which filters blue light and adds an orange hue, can sometimes be mistaken for faulty auto brightness.
• 🌡️ Additionally, color temperature adjustments can alter how you perceive the screen's brightness.
