IPhone 4 Camera is very blurry?

So I broke the back glass and then noticed later that the camera will not focus and is very blurry. I took the back off and found out that if I push in the lens, the picture becomes clear. Can I fix this?

Problem in camera need to change

Highly unlikely that you can fix that problem, or that even a good workshop could fix it. Those optical devices are precision made to within hundredths of a millimetre. Nobody can re-assemble such items perfectly.

I think you just did!

  • Why is my outer iPhone camera so blurry? I've tried cleaning with my lens stuff(and made sure its not a finger print). I've tries turning hdr on and off. What should I try now? What could it be)
  • Why do I do this? I'm very very very tired yet I don't want to sleep? I want to sleep because I'm practically blinking and bobbing my head side to side like a drunken man but I just don't want to sleep. I watch tv or go on Facebook or play on my iPhone. And I'm starting to get dark circles. And as a guy I don't wear. Concealer or whatever
  • My iphone screen is very dark, but if I look very close, I see the apps slightly? My iphone screen is very dark but I still see the buttons slightly, but I have to look very closely in order to. It is definitely not the brightness, because the brightness is set to 100% and its way too dark anyway. I tried restoring my phone and turning it on and off, but nothing is working. Please help. What do I do? I literally threw it out of anger and its fixed.
  • My iphone 4s is charging very very slowly? I let my phone charge for about three hourse and it only charged from 3% to 5% and its really really slow; i'm not sure if its the battery or not. Also; i had finally charged it to 10% and i took it off the plug for a second the. It went back to 1%.
