Camera opening custom viewer app


Sep 18, 2021
Hi, a question about the Camera on xiaomi.eu_multi_MI11Pro_MI11Ultra_V12.5.12.0, the version should be 4.3:
Is this the right sub forum to ask?

On the preview picture, the Camera app always opens the MIUI gallery viewer. How can I make that opening my custom app F-Stop? I already have set this app as default for .jpg files in the MIUI file manager. So the file manager does open F-Stop as default now, but the Camera still uses the MIUI app.
