[!NOTE: extreme care measures are taken just to avoid damage to the autofocus mechanism..]
i've heard a lot of complaints with the w810 camera..
i've experienced the problem myself. so i did it the old fashion way. fixed it myself.
pros:
- no more spots on your picture
cons:
- you could damage your sensor
- you could damage your autofocus sistem, like i've seen in other tutorials (no offense
)- etc.. thus very risky
what you need:
- 2 compatible screwdrivers
- a tweezer
- a cutter
- de/soldering equipment (gun or iron)
- extremly (dry) soft tissue
- non pointy toothpick
1'st step:
dissasemble you phone using this video
or refer to other tutorials on this site or the service manual..
2'nd step: camera module disassembly
-put a sheet of white paper on your dust free working table
-remove the connection strip from the camera module using the tweezers

-remove the camera module from the housing.. and place it on the white paper
(i use white paper to build more contrast to see better)

-take the cutter and force it gently between the two parts of the camera module (see pic)
-and gently rotate the cutter until the glue holding the 2 sides, snapes.

-do the same in the other corner
-gently remove the cap from the camera module

-warning: do not bend the copper film..

-now take a screwdriver, and place it between the plastic case and the circular magnet
-gently move the screwdriver to break the glue, and force off the magnet
-do this in each corner..
-warning: do not insert the screwdriver too deep, it might damage the autofocus coil

-now gently take the circular magnet out with your hand
-it's important you take it out simetrically upwards, not to damage the coil

-next step, desolder the coil connections to the pcb

-using a blower, mealt the glue from the other side
-if not available, peal it of carefully and don't bend the copper film
-and then remove it from it's holding points

-remove the coil and lense from the module casing using your hand
-try to repair with your tweezers the damage (bending, if any) to the copper
Click to view attachment
-now clean the sensor
-take the tissue, wrap it around the toothpick and gently clean the sensor
-meanwhile, blow some air on the sensor, from a safe distance (about 20cm) to avoid condensation
-visually inspect the sensor up closely, with a lens if any, for any dust particles remaining

if desired, same cleansing procedure with the lens.
that's about it.. clean pictures from now on
assembly is simply reverse engineering
3'rd step: assembly:
-mount the coil an lens corectly
-place it into it's holders on the casing
-solder back the coil to the pcb [or pba, whatever]
-gently mount back the magnet

-no glue required.. maybe some tape around the casing to assure that it holds.
hope it's usefull.
ps: i don't assume responsability for damaged camera modules, that is stricly your problem.
