Comes up with USB Blocked Connection when putting headphones in

[Nath9430]

Hello, 

I recently bought Samsung in ear phones and they've worked well but tonight the phone says USB Blocked Connection and I've tried sorting it via autoblocker but it just turns in to charging (obviously doesn't charge) 

But when you do use the charger it's fine and works. So just a little confused, any help or advice be great thanks!

Hello @Nath9430 and may I extend a Warm Welcome to the Samsung Community Forum 👋 

Can you try the headphones 🎧 with another Samsung phone as a process of elimination 🤔 

Perhaps try > Usb reset.

Settings > Apps > Tap the 3 lines with the downward facing arrow, to the right of 'Your apps' > Show system apps (toggle this on) > OK > Scroll down, and tap on 'USBSettings' > Storage > Clear cache > Clear data, then restart your device. 

• Clear Cache Files from the phone's System Partition Section  > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop or use a Tv's USB Port to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too { Possibly excluding the s²⁴ Series of phone's }

Unable the autoblocker if you have it set to maximum protection in the settings is one work around according to various sources.

@Nath9430 assuming your "Samsung in ear phones" are wired through USB-3 or dongle;

1-check if you can find them in the "settings > connected devices"

2- activate the developer mode and check that "Disable USB audio routing" is not checked

3-in developer mode, try to choose a different option for "default USB configuration" and see if any makes it work

4-Of course the "Autoblocker settings" make sure you do not activate the strict option, you may need to turn the Autoblocker off altogether.

5-Try what @BandOfBrothers recommended regarding clearing the cache.

@BandOfBrothers Hello there 😊 I tried checking "USBSettings" and couldn't find it on the list of settings apps. There is something called "settings" on the list but not specific to the USB. kindly note that I am using the most recent One-UI6.1.1 update on S24 series.

Thank you all for your help and advice I really appreciate it, however sadly none of these options worked. I'm guessing it's just that these headphones are now faulty after a week purchasing

Highly appreciate all your help though once again!

Final thing to test try them on a laptop and see if they are functional
