UI Q&A

Q1：How to understand UI display？

Contrast with dump fb buffer:

dd if=/dev/fb0 of=/mnt/fb0.bin /Path: mnt, which can be changed to the path you need, then use 7yuv or other tools to open buffer, choose the correct format (ARGB8888) and FB_WIDTH and FB_HEIGHT in fbdev.ini.

Q2: How to hide the UI to check if the problem is caused by VIDOE or UI?

Command to hide/show UI:

echo GUI_SHOW 0 off > /proc/mi_modules/fb/mi_fb0

echo GUI_SHOW 0 on > /proc/mi_modules/fb/mi_fb0
