Hi,
I'm running Sailfish 3.0.1.11 on my Xperia XA2. The colors of the photos sometimes have a blue tint if I use the flash 20190108_202706.jpg and they are not very accurate.
The autofocus works sometimes not very accurate, too.
Greetings, Frank

I have also experienced this problem.
Whenever I really have to use a flash for my pictures (I try to avoid flash whenever possible), then I simply manually adjust the white balance from "AWB" (automatic white balance) to the "light bulb". This normally fixes the weird colours and lets me take acceptable photos with flash.
However, the camera software needs some reiterations. Especially autofocus and white balance are off in roughly 1/4 of the pictures I take.

In my case i noticed that the AWB balance not solve the issue.
I remarked that mostly if i make a photo with flash, the AF use the flash too.
Quite at the start of the AF process, the flash light on 1st with a blue light, which goes in warm white then.
At the end of the AF process the color of the scene on display is quite good.
But the photo is then destroyed with the blue taint, because of the short light on by shooting.
that you can take any type of balance.
The taint goes in blue if you have the iso smaller or = to 800iso.
Especially if contrast is or below 0,5.
And most of the time in combination to the flashlight usage.
I don't know what i've done and how, but i had a picture with yellow/green (lemon?) taint.
Seems to me that by AF process and taking photo, a process bring some wrong colors. Is that a compression process? the balance filter?
Duration is too long because the eye is aware of it too.
Maybe there is an other balance correction for the flashlight. And the combination with the UX one, or the cancelling of the UX one is buggy.
I would suggest to the dev team to put the flash light something longer before shooting.
Or combine the AF with shooting if flash light is desired...
What weird is, try to take a photo of a scene which is completely yellow. best case as macro photo. just target of the scene with camera app closed or in background, and open it in front of the scene. Then directly the camera app display the scene with a green lemon taint. taking a photo at this moment let the green taint on the photo. Moving don't change it, until that an other color comes on the scene (then it displays the correct colors).

Err. The XA2 has one flash led. There is no variation in color temperature.

I don't know what i've doen and how, but i had a picture with yellow/green (lemon?) taint. Seems to me that by AF process and taking photo, a process bring some wrong colors.

Hello, I have also observed this problem. It seems to be related to the camera flash. If I disable the flash, I do not have the blue in the picture
MichaelS ( 2019-01-08 21:52:52 +0300 )editI also suffer from this problem. When you take pictures of humans with flash, they often look veeeeery ill on the pictures and will never allow you to photograph them again ;)
Daniel.T ( 2019-01-08 22:20:59 +0300 )editI have same problems. And AWB doesn't work properly and it turns black when i put +2. Especially front camera shows now many tiny little colored dots when I try to take a photo.
Comparing to Android-version camera and video camera are now much worse at the moment.
My device: Sony Xperia XA2, H4113
