Third-party apps and lower picture quality

Hi all,

I have been trying various document scanning apps, but the results are always very blurry. On the contrary, photos taken with the default camera app are overall good.

I think this might be related to the following issues reported with camera use in third-party apps Bad quality photos when taking them through messaging app Blurry pictures when taking through apps (bank app, messaging app, etc)
Does anyone know how to solve this?

I am running /e/ OS 2.3 on a Murena Fairphone 5.

Thanks!
