Hey @Thomas, this is from Huawei's American site FAQ:
What is the default saving path of pictures or videos? How do I change the path? 1. When the SD card is available: -- The default saving path for pictures is sdcard/DCIM/Camera. -- The default saving path for videos is sdcard/DCIM/Camera. 2. The path can’t be changed.
You might be able to get an app to change the path or root your phone and change it that way, but I don't have any experience with either of these options.
