I broke my S4 screen while celebrating my team scoring! I looked up the local phone shops but they are too expensive. Anyone know what I should do? Maybe buy a screen off eBay? I have been told S4's are a nightmare to fix yourself, is that true?
Is your whole screen assembly not working or did the screen glass just fracture?
A quick google search. Replacing the whole assembly is indeed some work.
If just the glass is broken you may remove the broken glass with a heating and replace it with a new one with a relatively low price to it.
I've never performed either of it, but both procedures do look risky. There are some good YouTube videos about the glass replacement. But as always you could render your phone unusable.
