Partial touch is not working in android kitkat

[archanaharish]

 As I'm new to android ,please correct me if I'm wrong. We are porting android kitkat to SAMA5D3 development board which is of size 480*272  (pixel), only partial touch input is happening like drop down and Setting page when I keep giving inputs randomly and nothing else. But touch works very nice with  Evaluation Kit which is of size 800*600 (pixel length).

Please help me fix this.Is it a density issue ??

            One more thing is ,porting is in forced landscape mode .But as our application is in portait mode , rotation has become upside down(270) which is one step anticlockwise to landscape mode. Is this causing touch issue?? Please help fix this.

Hi Igor,

                The cause of touch issue is, it is taking requested height as 19 instead of 480 in WindowManagerService.

I/WindowManagerService( 1418): relayoutWindow  win.mRequestedWidth272
I/WindowManagerService( 1418): relayoutWindow  win.mRequestedHeight19
I/WindowManagerService( 1418): AOSP:::updateFocusedWindowLocked
I/WindowManagerService( 1418): AOSP:::computeFocusedWindowLocked

Hi Igor,

I 'm confused whether it's an issue in Linux or Android part. Please

clarify me.

Hi Igor,

I tried to change in edt-ftx06.c file. Still it's not working. One more

thing is, touch inputs are working perfectly in evaluation kit which is of

size 800*600 but not in development board. What might be the cause?
