Thank you for your support of the Redmi product. The phone has been inspected strictly before leaving the factory, so you can rest assured of use.
If the brightness of the Redmi Note 14 Pro 5G automatically decreases when it heats up, please refer to the following details:
1. High brightness levels generate more heat, especially on OLED screens. If the phone is already hot, reducing brightness helps minimize additional heat generation;
2. When the phone heats up, the system throttles performance to cool down. This includes reducing display brightness, processor speeds, and other power-intensive activities;
3. To improve the clarity of the displayed content, you can first try to manually increase the brightness of your phone screen or cancel the auto brightness and manually set an appropriate brightness level.
