Hello All,

I need some help, checked the android documentation and related area, did not get a solution. This is on screen size for tablet devices during the boot stage.

Problem statement:
The device is a 7" LCD device (H=480, W=800 device), when Android boots "SYSTEM UI is not loaded" message pops up and the navigation/notification bar does NOT appear/display. However all operations like screen navigation etc are all working and we are able to navigate through a mouse!!!

I am using a customised version which is a slight offset of SNOWBALL LINARO ICS.

I understand the issue that it is a matter of setting the screen and device resolution. I had set the "ro.build.characteristics=tablet" in build.prop and rebooted, did not see any effect. Please note the lines in bold, blue.

Can you please help me to solve this problem.

Thanks and Regards,
Venkat.
