[Samsung Galaxy Mini] nadiren:
nope... i didn't...

btw the file we need to edit is incallscreen.xml under res/layout in phone.apk... all the sizes are taken from the "parent" meaning taken from the caller file.. i've tried to change it to static numbers but it didn't work.. take a look at it, may be you can do it..

this is original:
