Do you have any system logs?

To turn on the light, an applet has to be selected (tap on icon).

A quick glance in the log files in my Android phones (gingerbread to jelly bean), turning on the lights triggers a graphics to change the image on the screen. In my case, OpenGL ES Shader is triggered. If, (big if) you have the system log, you may (big may) find the entry for this graphics activity.

Find a near-identical phone, and experiment with it.

jhub thank you,
i have not system logs.
do you know log file name or extention?
where is log file on phone internal memory, which path?
i'm using XRY and UFED physical analyzer for mobile forensic, i dont see a log file in report.
maybe, i must find a event viewer software for phone, i like windows )

You can access the logs via adb by doing "adb logcat"

However the logs are not stored in the file system but in virtual files under /dev/log/. So they are cleared if the device has been rebooted. Also, if the device has not been shut down, the logs will be overwritten after a while.

I've tried "adb logcat" command, but software was alert "no log file"
Hovever i tried "adb bugreport", occured a long and complicated process results report
I do not know how to review the results
