Display started off with one (1) single horizontal line in the middle. it increased on a daily basis until after about 10 days, the screen was completely blank.
As a first timer at phone repairs, it took me about an hour to take apart and re-assemble phone. Smartphone repair kit was excellent, no regrets buying this whatsoever. I was abit scared to use the suction cup cuz i wasnt sure what would happen when i started pulling it apart, but it worked quite well (will get an iSlack soon enough) The most trouble i got was connecting some of the cables and the front camera/sensor bit. Other than that, easy as pie !!
I have a 4s cracked display and home button to fix in the near future....
I shall return for parts !!! Might even add this to my list of services that i offer (feeling like a pro)
Just follow the step by step guide and have patience when re-connecting cables. If you have the Smartphone repair kit, use the tray slots for screws and small parts going from left to right with steps 1, 2, 3 etc.
