Hello every1. i have the same blackening of screen & gave it to the service centre, they put me on a hold for a month and half and said this was a IC problem & they ordered it and after geting the IC they wil fix it and let me inform. so after 1.5mnths they called me back and said the IC was replaced and test it before me, my phon was working ok. But while i came hom & after recharging the same problm persisted. again i went to servc centr and they coud not find the prob and again put me on hold for another one month without any resolution. so i intentionally borought my phon back. but miraculously now the phon starts working and al the aplications are now working properly.
