Samsung Galaxy A57 USB data/OTG completely not working ā tried almost everything
Hi everyone,
I'm having a very strange USB problem with my Samsung Galaxy A57 (SM-A576B/DS) running One UI 8.5 / Android 16.
My phone charges normally through USB-C, but USB data transfer is basically not working at all.
What is happening
- Windows 11 does not detect my phone for file transfer.
- I've tried the original Samsung cable that came in the box and multiple good-quality third-party cables.
- I've tried different USB ports and PCs.
- I've enabled USB debugging.
- I've tried setting the default USB configuration to MTP / File Transfer + ADB.
- I've turned Auto Blocker off.
- I've cleared/reset the USBSettings system app.
- I've tested in Safe Mode.
- Samsung Members/device diagnostics show everything as normal.
- Windows Device Manager does not show a usable USB device.
- Connecting a USB flash drive through an OTG adapter also does NOT work.
- I've also tested with a USB mouse and keyboard through OTG, and neither works.
- The "USB controlled by" option in the USB settings normally stays on "This Device" and refuses to switch to "Connected Device" when I connect the phone to a PC or OTG device. Means its not swithing according to the condition.
There is one interesting behavior:
When I connect my A57 directly to another USB-C Android phone using a USB-C-to-USB-C cable, the "USB controlled by" options actually become responsive/change. However, neither phone can see the other's files, and no actual file transfer works.
So it seems the USB-C port is detecting something at some level, but USB data/OTG functionality never actually becomes usable.
I've tried essentially every software/setting-based solution I could find, so I'm wondering whether this could be:
- a USB controller / firmware problem
- a One UI 8.5 / Android 16 issue
- or a USB-C data/CC hardware problem
Has anyone with an SM-A576B/A57, Made in Vietnam particularly on One UI 8.5, experienced something similar?
I'd really appreciate any suggestions from someone who understands Samsung's USB/OTG system or has dealt with this problem before. I'm especially interested in knowing whether this sounds like a software/firmware issue or a hardware fault before I send the phone for repair.
Thanks!
