Hi Leonardo,
This ANDROID text is display by the init process when booting up. You can see the source code here for Marshmallow:
Cross Reference: /system/core/init/init.cpp
Here is the equivalent for KitKat (not sure which version you use):
Cross Reference: /system/core/init/init.c
Here is an example of how you can skip it:
init: allow to skip the ANDROID text at bootup · boundarydevices/android_system_core@b5f0f48 · GitHu...
The above requires to add the following to your init.freescale.rc:
on early-init
setprop ro.init.skip.text 1
Regards,
Gary
