My Google+ Photos seen on Phone is different from that seen on Web
My Samsung Note II phone died and I have just replaced it with a new Asus ZenFone 2.
The Google Photos app on my Lollipop ZenFone2 phone says "Auto Backup up to date 5,953 photos", and it shows all the photos in my Gallery app, and also all the old photos backed up from my Samsung phone.plus.google.com
on my PC under All Photos also says 5,953 photos. However, I can see only photos taken from the ZenFone's camera. Missing are WhatsApp photos and screenshots in the ZenFone's Gallery app. Thinking it could be a synchronization delay, I waited for a couple of days but it's still the same. (Anyway, photos taken by the phone camera can be seen from plus.google.com
almost immediately if my phone is on wifi.)
What could be wrong? Are my other Gallery pictures really safely transferred to the cloud?
If it is of any help, on my ZenFone I have configured the camera pictures to be stored on an external microSD card.
