I did the same thing 2 months ago with uBreakIFix. Worked well for 8 weeks and then the problem has come back. I don't drop my phone and don't load weird apps onto my phone.
There's something wrong w/ the design of the camera and compatibility w/ this phone....once we're outside of the warranty, we will no longer have coverage...Samsung needs to own this.
I am facing the same issue with my Note 9. The live focus and the x2 zoom are giving blurry image and the phone is producing a buzzing sound everytime I zoom or open live focus. I did all the recommended steps (clearing cache, safe mode, etc.) And the issue is still there. What was the solution for this issue?
I have this issue as well with the optical zoom. I have tried clearing the cache and going into safe mode to no avail. As a matter of fact it's gone from an occasional nuisance to an all the time thing. The phone is only a few months old and the camera is crippled.
