Hey there,
I'm trying to figure out what is wrong with my phone (Zenfone8).
As you can see, the picture is alright but when I use the zoom the picture goes all pixelated (uploaded in a comment)
I change the camera module but it still does the same :(
Any clue/help please...?
EDIT I rebooted the phone to stock settings and the camera is acting the way it ought to...very weird.
I guess there was some apps the camera didn't like...
It seems like the phone is applying wayy too much of some kind of sharpening filter. Are you zooming in very far? Cuz it may be trying to compensate for digital zoom by sharpening the image afterwards. If you've got a Pro mode setting on the camera app, maybe try using that instead and get closer to your subject, if possible. Pro mode should hopefully stop the app from applying any touch-ups to the image it thinks it needs.
As a workaround you could also just take the pictures without zooming and then zoom in afterwards with any image manipulation program. It's technically the same thing. Minus whatever "enhancements" your camera app is applying.
The downside is that you're then zooming in on the compression artifacts and all the "enhancements" we've all learned to "love" over the past decade (thanks, Google!), while the in-app zoom probably works with raw image data before zooming in.
That image has a lot of non repeating textural detail. My guess is that the error is caused by some compression setting or file type conversion. You might look to see if you can change the file type and compression level somewhere in the settings.
Just because the picture is larger does it mean necessarily that it's clearer. Although it does seem that you've solved the problem in the in this case that isn't the case. But in real life there is no zoom and enhance - You're not getting a license plate number off of a reflection in a screw's head.
I have Zenfone 10 too, and I would say it isn't worse than iPhone in sharpening. But anyway you could always use pro mode, where there is no such problem.
