My Note 8 is having problems with touch screen responsiveness in some areas it's completely dead to touch input. Ive contacted Samsung and as phone is under warranty, they said send it in as free repair. I've never dealt with Samsung for any service or warranty repairs. my concern is the screen has the tiniest hairline crack across it, generally cannot even notice it when using phone. Question is will Samsung try to charge me a cracked or broken screen fee after receiving it?
