2.2.9 Why does my phone's screen look
bright/red/unclear/blurred?
Phones use different screens to improve the display quality with better contrast ratio and a
wider color gamut.
1. Your phone uses a negative LCD screen, providing a darker dark state, compared with
ordinary LCD screens; a brighter maximum brightness, brighter bright state, and a
contrast ratio of 1500:1. Your phone's screen will not look blurred with a negative LCD
screen.
2. Your phone uses a high color gamut screen with 95% color saturation, providing brighter
colors. This new technology makes your phone's screen very different from ordinary
phone screens. These are not technical faults. Please rest assured.
2.2.10 Why does my phone's screen turn off during a call?
This is normal. When your ear or another object blocks the proximity sensor near the receiver,
the screen automatically turns off to prevent misoperations. The screen will turn back on after
you remove the phone from your ears.
Please do not block the area around the receiver with a phone cover or other objects. When
attaching a screen protective film, please make sure the proximity sensor is not covered.
Protective films that are not very transparent may cause the proximity sensor to malfunction.
2.2.11 Why does my phone's screen look red the moment it turns
off?
Your phone uses a high color gamut backlight. When the screen turns off, the red spectrum of
the backlight turns off slightly later than the blue and green spectra do. That's why your
phone's screen looks red the moment it turns off. This is a normal phenomenon. Please rest
assured.
2.2.12 Why does my phone have a red frame on the screen?
Please check if you have enabled strict mode under Developer options. The menu path is as
follows: Settings > Developer options > Strict mode enabled. If strict mode is enabled, an
application performing long-running operations on the main thread will cause a red frame to
flicker on the screen.
2.2.13 Does the 2.5 D glass screen break easily? If the screen
breaks, can I replace just the cover glass?
1. Your phone uses Corning Gorilla Glass, which is very strong.
2. As your phone has an all-in-one modular design, if the screen breaks, you will have to
replace the entire front cover component, which includes the screen and front cover.
