Why Are There Black Bands At The Top And Bottom Of The Screen - Huawei P8 Faq

12.13 Why are there black bands at the top and bottom of
the screen?
There are 2 mm to 3 mm thick black bands above and below the phone's startup screen. This
is due to overlapping UI elements and is completely normal.
12.14 Why does the screen on my phone have a red tinge
or why is the screen blurred?
Some Huawei phones (such as the Honor 6 Plus and P8) use a new screen technology which
offers better contrast and color accuracy:
1.
2.
12.15 Why does my screen automatically change or why
does my phone automatically open software?
1. If the screen automatically changes when your phone is charging or connected to a
computer using a data cable, the voltage may be unstable or the data cable or charger is not
original. Over-high voltage causes interference on the touchscreen. The touchscreen may
incorrectly detect touching actions. Therefore, use original charger or data cable provided by
Huawei.
2. Connect your phone to a Wi-Fi network. Go to Settings > Updater > Check for updates.
Check whether any system update notification exists. If yes, update your phone to the latest
version.
12.16 Why is my phone's touchscreen inaccurate when
playing games?
If the touchscreen on your phone is inaccurate when playing games, please ensure that you
haven't hidden the virtual navigation bar at the bottom of the screen. If this is the case, you
simply need to swipe up from the bottom of the screen to restore the navigation bar. This
should address any problems with touchscreen accuracy.
These phones feature JDI displays which support local dimming and are brighter than
ordinary LCDs. The displays have a contrast ratio of 1500:1, compared to 1300:1 for the
iPhone 6 Plus and do not suffer from blurring.
JDI displays have a color saturation degree of 85%, compared to just 60% for the iPhone
6 Plus. This helps recreate vivid colors on your phone. This is a completely new display
technology which can't be compared simply with ordinary phones. Please rest assured
that there is nothing wrong with your phone.
