What is Heated popup? (System UI & Settings)
Function
1. Previous models: If you adjust brightness when the device is heated to reach a certain temperature,
a pop up that says “Cannot brighten due to high temperature of phone.
Try again later” will appear, and brightness cannot be controlled.
2. G4 : Pop up does not appear as slider bar can be controlled. However, there is a maximum temperature for a phone,
therefore the settings will be modified again even though you force to control brightness settings.
Home → Indicator Setting → Display → Brightness
