For some reason my camera version is different to my wife's, i cant remember the exact version number of her camera but it is newer than mine that is for sure.
My camera version is:
Her Nokia 8 is only about 3 weeks old where as mine is a year old, i cant see it but it does make you wonder if there are also hardware revisions.
So based on a not very representative of the whole user base 3 people, 3 people are all running a different camera app, how odd.
I got all 3 of the released updates since the pro camera app was released and somehow i have ended up without a single update lol
I have thought about getting the APK but surely to god at some point HMD are going to release another update that is actually meant to be and puts us all on a level playing field.
