The computer doesn't detect my Samsung S21

[Andrzej_PL]

I have a Samsung S21. Around this summer, an update arrived that caused my computer to no longer recognize the phone as a USB drive.

As a result, the phone's memory got filled with photos, and I can't transfer them to the computer.

When I connect the USB cable, the phone only starts charging. I've tried 3-4 different cables. I've attempted to reset the cache and data in the USB settings, but it didn't help. I also tried downloading the Samsung Kies program, but it didn't allow data transfer either.

I want to emphasize that I am an advanced computer user.

Under developer settings there is an option to configure which default you would like.

Not sure if it will help your cause

For developer options go settings> about phone > software info and keep taping the build number till it says developer mode is enabled
Then go back to settings page it will appear asthe Last option.

Also make sure nothing is changed on your PC

Install smartwatch, which will install the latest usb drivers. Also, make sure the phone is unlocked when you connect it.

GoanGeek, thank you, it worked! You've made my day!

Please can you try heading to 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.
Next time you connect to your PC using the USB cable that came packaged with the phone, please try swiping from the top of the screen to the bottom, and check the notification panel to see if the connection has been recognised, and tap the notification to explore your available options. Let me know how you get on.

Are you still having this problem, iam able to solve it.

After 6.1 update on my samsung s21 plus on 22 sept 2024, my phone was showing slow charging, not detecting on laptop and my toyota rav4 is stopped detecting it at all, i went to phone repair shop thinking i got fried usb port but after changing the port it still didnt worked. I tried all usb debugging default usb setting cache clear nothing worked and i tried something funny which worked and every thing starts to work.

I took a usb c to usb c cable and connect my phone to my son old Samsung Tab A7 and as expected my phone showed no notification but my son tab start to charge but no data transfer. From that tab notification i clicked usb control from other device to this device and selected file transfer. Suddenly phone s21 shouted what should i do with this incoming connection(i havent seen this notification since the update 20 days ago) i selected mtp on my phone and selected always(asked just once or always) after this the Tab ask storage sharing permission which i gave it. I restarted my phone as it starts to freeze keeping the cable intact and voila, now i can connect my car, charger head phone every thing. Thankyou samsung for the buggy update.

Check the attached photo of TAB and make sure to select MTP as always on your phone after doing what you see in the picture. And restart your phone if options greyed out while keeping the cable connected to each other

Hello GoanGeek,

Thank you for the clue, but this did not work for me.

Please, suggest any other options, which may help.

Hi.
Please create a new post explaining what issue you are having.

Other option I would suggest is try resetting your settings only under Reset if it was working before.

Hi,

This doesn't work for me either.

It's urgent to transfer legal stuff from phone to PC.

My IT is in French but I found all that you mentioned and tried to no avail.

I even bought a new cable us now just in case.

Freaking out - I have my Dell since 2022 and my A4 phone since 2023, never had these problems before.

CAN YOU PLEASE HELP?

Cheers,
