[theyoungstone]

Describe the bug

I have just updated contacts to 3.4.0 version.
In the Web GUI, I upload an new picture for a contact.
When I synchronize the contract on my Android 10 smarphone with DAVx5 3.3.1-ose, the old picture is deleted but the new one does not appear. So the contact has not picture anymore.

3. Choose an picture
4. On Android device, synchronize contacts with DAVx5

6. There is no picture anymore

Actual behavior
The is no picture as if it was deleted

Could you share the contact with the picture please?
[email protected]

[theyoungstone]

I don't know how to share a contact.
But to try it, I have generated a new contact with only a name and a picture and when I synchronized it, the picture is on my phone. But if I update the picture and synchronize again, the picture disappear and the new one is not on my phone.
The contacts where there is no picture anymore are the one who I have updated the picture after the update of the application to 3.4.0.

[theyoungstone]

If I want to update the picture and synchronize it with my Android Smartphone, instead of updating it into the Web GUI of Nextcloud, I have to delete it and import a new one. If I import a new picture on the old one without deleting it before, the new picture is not synchronized on my smartphone and the old one disapear.

[skjnldsv]

So, to sum it up:

1. Have a contact with a picture
2. Sync it to android with Davx
3. Update contacts to 3.4.0
4. Change picture
5. Sync contact
6. Still sees old picture

Questions

1. Is the update to 3.4.0 necessary, if you do all of this on 3.4.0, does it still behave the same?
2. If you edit other fields, are they still synced?
3. What vcard version is your contact? 3 or 4?

Please export the contacts before and after it doesn't sync anymore so I can compare.
You can download them from the Nextcloud app or export them from your Android device

You can attach them here as `.txt. if yuo want or send them as attachements to my mail above :rocket:

No: So, to sum it up:

1. Have a contact with a picture
2. Sync it to android with Davx
3. Update contacts to 3.4.0
4. Change picture
5. Sync contact
6. There is no picture anymore into Android

And:

1. Have a contact with a picture
2. Sync it to android with Davx
3. Update contacts to 3.4.0
4. Delete picture
5. Upload a new picture
6. Sync contact
7. The picture is OK, the new one

But If I do all this after the migration, it is the same:

1. Update contacts to 3.4.0
2. Create a contact with picture
3. Sync it to android with Davx
4. The new contact with the picture is on Android
5. Change picture
6. Sync contact
7. There is no picture anymore into Android

And if instead of update the picture, I delete it and upload a new one, the sync is OK and the new picture is on the phone.

I tried to update the phone number or the email address of an existing contact and this modification is synchronized on the phone with no issue.

I don't know the vcard version. I am using Nextcloud 19.0.3, Contacts 3.4.0, Davx5 3.3.2-ose now and Android 10 with Google contacts 1.7.31

Export after picture delete and import.vcf.txt
Export after picture update.vcf.txt
Export before picture update.vcf.txt

"Export before picture update.vcf.txt"
--> I have the picture on my phone after sync

I upload a new picture instead of the existing one without deleting it before:
"Export after picture update.vcf.txt"
--> The is no picture anymore on my phone after sync

I delete the picture and upload the same one:
"Export after picture delete and import.vcf.txt"
--> The new picture is on my phone.

I hope my explanations are clear.

i can't replicate this when uploading an image manually, however, when syncing an image from twitter (or any available social network) what i have found is that two PHOTO fields are created.

one with the encoded image, and one empty field.

this empty field is causing images to not render in one of my address book clients.

[eleith]

if you later delete the photo, the empty PHOTO fields remain.

thus adding an image (even manually) later will not resolve the problem

i am able to get it working with a few small changes. this seems to only affect vcard 3.0. will put up a PR shortly.
