Iphone 4 broken screen and cracked front facing camera

I dropped my ATT Iphone 4 a few weeks ago and most of the upper third of the screen on the front cracked. This left a crack over the front facing camera. If I buy a replacement kit online, will that fix the problem (blurry picture), or will I need to buy additional parts to fix the camera? Also - are there any reliable, but affordable places to buy a screen replacement kit? Or any places I should avoid getting it from too, as well I suppose…

I've bought a kit from iFixit that worked on an older model. The iPhone 4 display repair kit they sell currently goes for about $70. The repair process is rated as "Difficult", and indeed involves temporarily removing many of the other components.

  • White dots on iPhone X front facing camera? I accidentally dropped something on my new X and now I'm paranoid about these two small white dots on my front camera? They don't show up when I take a picture, they're on th actual front camera itself. Is this normal?
  • What is wrong with my front facing camera? I went to take a picture using my front facing camera on my iPhone 4s and I noticed there were redish Orange spots all over it. What is it and how do I fix it?
  • My Iphone front facing camera won't work? I have tried resetting my settings and I don't know what to do? The shutters close and if you look closely at the option to switch to video it glitches.
  • Make app store think i have a front facing camera? I want to run the vectone app on my iphone 3gs but when i try to install it an error occurs saying that it is not compatible as i do not have a front facing camera. Is there any way this around other than changing phones as it is driving me crazy. my 3gs is on 6.1.3 with a redsn0w untethered jailbreak (as it is old boot rom model, early 2009) and cydia installed. i have the app on another device and it does not use the front facing camera at all. are there not any cydia tweaks to fix this?
