When my husband's Samsung phone screen crackled, I contacted several repair shops and they said that it was cheaper to replace the phone. It was going to be something like $145.00 ... it's been several months now so I don't remember exactly.
I Googled it and found that the Samsung phones have a double glass which makes it difficult to replace.
I found the next phone up on Amazon.com for $180, refurbished, like new, with charger. 4951
