So if you want to answer a call from the sview cover you need an app from market.
Well...my mod give you the chance to do it using the stock system app (SecPhone).
What I made was edit some lines in the code (Thanks to @tkari4 for the help) so the answer slider goes to the top of the screen...and you can use the window to answer with out open the cover.
I have to edit the app to get a better look....but the first version I make works great.
I only test this on DNv4RC KITKAT rom...so...I dont know if this mod works on others tw roms.
my test Sview mod by you.. Great
Just flash the zip.
