Hey dude can you send me the info also? Thank you!This is done by the SystemUI.apk which has been compiled by FYT for these units in combination with the other software.
You can't use another SystemUI.apk on these systems. Modifying this one would require "reverse engineering" the code in smali.
But you might be lucky: Booroondook of 4pda had modifiied the SystemUI of the uis7862 to display notifications, but I don't know whether that is in a pull-down or by simply displaying it in the notification bar by simply overwriting previous ones.
