Hi there,
I bought a mini 0805 camera on ebay and right out the box I found it has a out of focus problem. I decided to try to fix it by myself because I didn't want to send it back to china (and pay the shipment) and wait one or two months for the replacement, so this is what I did.
1. open the camera using a knife or other sharp object from the side of the camera, where the power button is located
2. Put the knife on the side, the cover is slightly glued so it's very easy to open
3. after remove the cover, you will see 4 phillips screws, remove them all.
4. Becareful when remove this ring with the holder because it has a very tiny small metal ball with a spring and it's really easy to fall and get lost
6. open the camera for the side with a flat screwdriver
7. locate the glue on the focus lens ring and remove it. I think it was very easy to remove because it was something like hot glue and not super glue.
8. plug a mini hdmi / hdmi cable to a computer monitor and start to rotate the lens, first clockwise and then counter clockwise until you see the objects more clearly and not blurry. I focused on a wall clock at 5 or 6 meters from me and adjusted the lens until I saw the numbers clearly
Finally, the results.
Before:
After:
I uploaded two sample videos with the before and after.

I'm very happy with the change, now I have to play with the exposure because some videos are really dark (when the sky is to bright):
