what is this black dot on my phone screen after screen replacement ?

[Android Central Question]

HI,

My samsung phone display has been broken. After enquiring with samsung customer service they quoted me a hefty amount of money for entire LCD replacement. So i went to local shop . They quoted me reasonable amount to change glass instead of LCD but after repair there is a strange black dot on the screen which looks like dead pixels. He said it is something because of heat during replacement. He told me that it would go away in 3 days otherwise he would change it free of cost. Should i not worried ?. Did he just screwed up my phone

Welcome to Android Central! Dead pixels can sometimes go away. Since the display was broken in the first place, you were probably looking at a replacement screen anyway. If he's offering to replace it free, then wait 3 days and accept his offer.
