I’ve just got a new phone and am setting up some pre-existing sync folders to be shared with it. These folders were the ones I used on my previous phone and my laptop without any odd behaviour.
When I add my new phone to the share list, it downloads all the files without fault onto the new phone, but then something weird happens - a (seemingly) random selection of those files get ‘modified’ by the new phone and the modifications are synced back to the originating computer. I can’t detect any modifications at all, the files look the same, have the same permissions and seem to have the same timestamps (I can’t check but the timestamps are all well in the past, not updated to today or anything like that).
Can anyone explain this odd behaviour? Nothing seems to be wrong with any of the files, but it’s a bit disconcerting to have an otherwise blank (factory reset) device apparently ‘modifying’ my files without my permission!
