My iphone 4 camera shutter was stuck so i bought a new one online from amazon.com and replaced it. the problem with this is that the camera does not focus especially on text. If i purchase a camera from ifixit, will it focus on text? ( I use my phone camera for notes so it’s really important)

Hi mate, Sounds like you have purchased a poor quality camera. When purchasing ANY replacement parts, only buy from reputable suppliers and ensure the goods state they are original iphone parts. A lot of the parts floating round the ether are very low quality fakes produced in Asia for peanuts. You would be safe with this part from iFixit. Hope I helped.

i think it, normally is the new camera good as it not a logicboard problem is.
