Hi, in every image are the same problem, left side specially left lower corner are blurry, lens is clean no problem there...
This is a new drone just got it about a week ago, images been like this from the start.

Same thing here..

I think the problem is worse on still images, video is at least ok.

What temperature are you operating in. You may get some focal shift if you are below 0 celsius.
The operating temperature is 0-40c

I might be wrong, but I think the issues is your lens is fogging up due to the weather.
One simple trick to see if that is the issue is Liquid Dish Soap – Some people use a small drop of (mild) dish soap on a soft cloth and apply it to the inside of the lens, then let it dry and buff just enough of it off to provide clear vision.

Well I have been shooting few times and temperature has been around -5 to +1 celsius, i think I need to take some pictures inside the house and if the problem is still there, then it is not about the temperature. I will add sample picture after I have done this.

picture taken inside, no fog on the lens... lens is clean, but still the left lower corner blurry, not good not at all

My first P3P that  I got replaced due cracks in the hull had a camera that video and picture was crisp and sharp.
Now I have sent in the replacement drone for the second time to have the camera fixed.
Picture are unsharp and blurry compared to the first drone. Overall lower quality on the whole picture and some spot like yours with serious unsharp areas.
Seem that they have a batch of cameras out here that are crap.
So raise a support ticket and send it in or take to your dealer. This time a send it back with some printed picture so they really can see the problem.
Their test at the repair shop in Holland seem to be limited .

See if you can get a high resolution copy of a resolution test chart.  They are designed to test camera resolution and lenses.  Point the camera at the chart in good even light so that the chart fills the camera view, and the edges of the chart touch the edge of the camera image.  If you look at the "corners" of this one, you will see four shapes, roughly like a +.  They will have parallel black and white lines, converging closer as they approach the middle.  What you are looking for is the point where the lines change from distinct black/white lines to a grey blur.   Next to it is a number.  In the example picture it shows that the transition point is next to 4, meaning 400 TV lines of resolution.   The number is approximately the same in the vertical and horizontal, and in the 4 corners.  There is a similar set of lines in the center of the image which does the middle of the camera/lens.   It shows this camera/lens has a consistent resolution across the whole range.  You may find the center of the picture is slightly better due to the way lenses are made, which is normal.

If you test your camera and there is a "soft" area, it will show up as one corner will have a lower result than the rest.  This will indicate a fault, it could be something a simple as a thumbprint on the glass, through to condensation, mould or other contaminants behind the glass.  It is an optical problem and is highly unlikely to be an electronic problem.  I'd suggest it is time for a warranty support ticket.

I tried to find a suitable chart doing a Google search but they do not seem to be big enough with enough resolution to test our cameras.  You might have better luck.  They still might be good enough to show the difference between the bottom left and the rest of the picture.

OK, I will contact the dealer and let's see how it goes from there...

That is a good way to test the camera.

Yes, I tried to do that but test pics are really bad... P3A camera are not suitable for close ups ;)
and I can't print bigger than A4 test charts, well maybe that camera just are really bad, have to learn to live with it

The camera on a P3 will not be in focus if the chart is so close you can fill the frame (unless you have a 20ft printer!).  The target needs to be around 4 metres away.

The only way to do it is to take several photos with the target chart in a different place each time (but the same distance), keeping all the settings the same in manual mode.

Try  drawing something like this in Photoshop or whatever at high  resolution, and print it out as large as you can. Then place it at a  distance where it is in focus, and the lines converge and blur somewhere  along the scale.   Keeping the distance from the chart the same try  testing various points in your camera image.  As long as the same area  is in focus, the whole face of the lens is the same.  If it works out  the bottom left is a different letter from the rest of the picture, it  will demonstrate a problem that you can take still photos of, to support  your claim for a faulty camera.
