jpeg don't pass on mac android 5,1 on soyes 6,1, photos on SD card (FAT32), not on the phone storage;
when connected the jpeg don't open on mac's aperçu, announce corrupted (missing meta dates); on the phone (android) it appears normally.
what's wrong ?
Problem solved...:
I started directly using the phone choosing SD for memory, including of course photos.
And that problem came out. Untill I changed tothe phone memory, then photos are normally available on mac. Going back then using again SD as memory, the problem is gone, photos available also on mac. It looks like it was necessary to start photographing at leaast once with phone memory, BEFORE switching to SD memory. Now it works.
Hope this will be usefull to other soyes users...
