ITS theme changed after kernel upgrade 742

Hi Team,

we recently upgraded kernel in Development and Quality from 741 200 to 742 400.

and noticed that its mobile theme layout changed in development ,quality system and fine in Production. we would like to revert theme changes to old in development.

what could be the solution.(attached screen shots)- we are using Motorola WT4100 bar code scanner 

Thanks in Advance
