Blurry photos are usually not the lens you think
When photos come out soft, the cause is either scratched or cracked lens cover glass, or a camera module whose optical image stabilization has failed after a drop. A rattling sound from the camera area when you shake the phone gently is the classic sign of a failed OIS assembly. Both are straightforward replacements.
Before you pay for anything, clean the lens cover with a microfiber cloth and try again in good light. A smudge from sunscreen or a fingerprint accounts for a surprising number of "broken camera" visits.
