JPG Pictures exported with affinity photo not showing on android phone

[Aquaria]

Hello and greetings.

I got a strange problem, when I finish editing my pictures in affinity photo and export them, to forward them to friends on my android phone, I can't see them on my phone. (Galaxy A3, Android 8.0)

I use the JPG format for exporting, since this seems to be the usual format for this kind of device. I tried different resolutions, DPI settings, changed the pixel format and the ICC profile, but nothing seems to work.

The profiles which I used, where Adobe RGB (1998), Pro Photo RGB and srgb iec61966-2.1. The last one is displayed in the info from the pictures of my phone cam, so I hoped it will work, yet it didn't.

Final workaround for now was to use a JPG picture from my phone and to copy and paste the desired picture in to that file, just too few and send it with my phone. It worked but this can't be a solution!

Another point which may be vital, was the transfer from Adobe Lightroom. I used the “external editing” option in Lightroom to send the RAW files to affinity photo. The settings which I used for the formatting process where: tiff, ProPhoto RGB, 16 bit depth, 300 dpi, no compression.

Question is, how do I make these exported JPG pictures visible and usable in my android phone gallery?

I hope someone understands my problem and has a better solution.

Try out and use an ICC profile which is supported by the phones display (color gamut), the overall common denominator should be the sRGB color space here. - Thus use a sRGB profile.

Try insert this JPEG file, if it will display on other devices.

Can't have a file extension problem? Affinity uses JPEG, and your phone may be able to accept only JPG.

Thanks for your help. Yes, i was using the sRGB settings but I figured out what went wrong.  When exporting the pictures the metadata / picture properties are displayed with the export date, still my phone sorts them by the date the original image was shot.

Because of that the images were pretty low in my folder and gallery structure, that's why I didn't find them. Didn't know that, thought they are always displayed by creation date.

So everything seems all right with the export settings.
