Images transferred with nextcloud are loosing GPS info in metadata.
The exact same image on smartphone transferred with any other app (e.g. Solid Explorer) show the GPS information.
For some reason the GPS info is removed when synching the data with nextcloud.
How to solve the issue in order to keep the GPS data in the metadata from the image?
Nextcloud version: 27.1.2
Operating system and version: Docker @ Unraid
Smartphone: Samsung Galaxy S23 (Android 13)
Nextcloud version (Android app): 3.26.0
I am almost sure that this is a bug in the nextcloud android app.
Because when i am using the Solid Explorer app on the smartphone (which supports also nextcloud) and transfer the image to nextcloud server then the GPS data remains in the image. Unfortunately Solid Explorer does not support auto upload of new images.
How to involve nextcloud android app developer to fix the problem?
Quite similar issue was also reported here in the forum from iPhone user.
I think it is feature on android app. It is for privacy purposes. It could be seen by bigger uploads. But I do not like that due to that I WANT exif data in uploaded images on server. I think user must have a choice about that data, not a programer. If there is need for hiding that data, it should be done on server, but via setting.
From more than >100 apps on my phone only 2-3 apps (including nextcloud) did not automatically fetch this needed permission.
Meanwhile i have stopped the use of nextcloud completelty because it’s by far to complicated to setup for regular backup of images and videos from my smartphone and some tablets. The installation (Maria DB + Nextcloud) is already the first hurdle then the setup on the nextcloud app. Regular updates of nextcloud have been also a nightmare based on my experience. Even leading to required complete new installation. Not to mention security warning popups and database conflicts.
For people who love to work with console nextcloud might be really great sync tool. Finally i decied to use android app FolderSync to transfer all images and videos via SMB share on Unraid. Installation, features, updates and transfer speed 100x times faster and no issues with loss of exif data.
I can confirm that all data is not retained. After the sync has completed, I tested by downloading an image from the NextCloud data directory to my PC using FTP. Also using FTP, I downloaded the original image from my phone. The original image from my phone contains the GPS data, while the copy that came from the NextCloud server had the fields still there, but they were all zeroed out.
The fact that all the information fields are still there makes me think the phone sync software is deliberately doing that, rather than simply not uploading it. A backup solution like nextcloud should never alter the original file.
You say that all your data is retained? Could you post your setup info - version you are using, and maybe, if possible, the GPS Exif data from one of your images? It is possible that the sync client is removing particular tags, and yours is different to mine.
