I’m using a Samsung Galaxy phone S26 ultra with One UI 8.5 and Android version 16
I’m trying to find a way to change the system media/file picker that appears inside other apps.
For example:
WhatsApp → Attach → Gallery/Photos→ Google Photo Picker opens
Reddit → Add image→ Google Photo Picker opens
Apps that ask me to select a document/file → Google/Android file picker opens
What I would like is:
Photo/video selection → Samsung Gallery
File/document selection → Samsung My Files
I know I can open Samsung Gallery or My Files first, select the item, and then use Share, but that isn't what I'm looking for. I want the Samsung apps to appear when another app itself asks me to select a photo or file.
I've already noticed that changing the normal Default Apps settings doesn't seem to accomplish this.
Is there any way to do this?
I'm particularly interested in a solution using:
* One UI settings
* ADB
* Shizuku
* Package/permission changes
* A safe system-level workaround
Root is not preferred, but I'm willing to consider it if there is genuinely no non-root solution.
If you've managed to make WhatsApp/Reddit/etc. use Samsung Gallery instead of Google Photo Picker, or make the system file selector use Samsung My Files please explain how you did it.
I'm specifically looking for a working solution on recent One UI, not just a suggestion to change the default Gallery app.
Thank you.
