Sunlight Readability Enhancement (SRE) mode is a technology that tunes the screen to show
content clearly under the sunlight. It was first seen on LG G4 for the first time in Korea.
How to use
SRE mode works when the outdoor illumination is 25000 lx or higher. It adjusts both the screen
brightness and color of each individual pixel.

1) Hallway / washroom : 50~80 lx
2) Office : 320 lx
3) Cloudy day : 100 lx
4) Day with clear skies : 1,000~25,000 lx
5) Direct sunlight : 30,000~130,000 lx
SRE mode enables you to see content on your phone screen under the bright sunlight.
