Seems to be x1
Reading the App blurb it refers to possible use of the wide angle lens by using the ‘settings’ app- don’t know what that means**
**you go to list of apps, select XP4N and the options for 48 mb picture and using wide angle are there
Btw …. Another bug is that you have to exit the xp4n app to see your image - there is a tiny preview but doesn’t last long and seems only to confirm that you have taken an image
When i skimmed the app blurb last evening I recall it referred to ‘for those who have got this far ‘ and then something about a setting but can’t remember what that was
