Why does part of the LCD screen become yellow, and the bottom portion dim, while the screen
colours and brightness of different areas uneven?
All Huawei products undergo rigorous display testing to ensure that their colour and brightness
fluctuations are properly controlled. This is normal and does not indicate an issue with your
phone.
To meet the preferences of different users, colour temperature adjustment is available. Go to:
EMUI 5.X and earlier: Settings > Display > Colour temperature
EMUI 8.X: Settings > Display > Colour mode > Colour temperature
EMUI 9.0: Settings > Display > Colour & eye comfort > Colour mode & temperature
Magic UI 2.0.1: Settings > Display > Colour mode & temperature
then touch or drag the spot on the colour circle, or touch Warm or Cold to adjust the colour
temperature to comfort your eyes.
What should I do if the middle area of the screen is insensitive, intermittently responsive, or
unresponsive to touch commands?
Perform the following to troubleshoot:
1. Ensure that you perform screen operations correctly when you are using the virtual
navigation keys. Touch the keys or icons precisely and keep in fingertip in contact with
the screen when swiping.
To prevent touching an app icon by mistake when you are using a virtual key, a narrow touch
dead-zone is set between app icons and the navigation bar. In addition, a touch dead-zone is also
set in the middle of the three navigation keys (as shown in the following picture). Therefore,
make sure you touch the centre of the virtual navigation key. If this affects your normal use, try
switching to the front navigation button.
