Hello, @traian.lorent
We discussed this with our team and they noted that different sizes of files from the phone, because the photo is not processed in the same way from the phone and desktop, and is not compressed in the same way.
If you enable image processing from the phone, there could be some bugs with images downloaded from the phone, for example, they will be flipped. Unfortunately, it is not something our plugin can influence on.
Thus, on phone devices were made faster uploading without image processing, to reduce the time and resources for phones.
Sorry for the inconvenience.
Best regards,
Zeroqode Support Team
