SUMMARY On two computers, both running up to date KDE Neon 19.08.0, we have this situation. STEPS TO REPRODUCE 1. With one or more Dolphin windows opened, plug your Android smartphone via USB (Samsung Galaxy S7 in our case). 2. Allow access on the device and click "Browse Files with File Manager" in the popup window. 3. Dolphin opens, but shows an error like "No media found. Check if the device is unlocked and MTP is enabled." OTOH, if I close *all* Dolphin windows before plugging the USB cable in the smartphone and then plug it in and allow access *before* opening the next Dolphin window, access works fine and I can browse the SD card and the internal memory of the phone. This may be libmtp related too, but I think the fact that Dolphin must not be running before plugging in the USB cable is a Dolphin issue, thus reporting to Dolphin.
Yep, can confirm.
I have similar issue with 20.12.2 on Fedora 34, although it shows error about 'udi=/org/kde/solid/udev/...' file not existing instead.
I can confirm this issue using todays git-master versions of frameworks, plasma and gears under openSUSE Tumbleweed snapshot 20210816.
I can no longer mount the MTP device even after restarting Dolphin. SOFTWARE/OS VERSIONS Operating System: openSUSE Tumbleweed 20210820 KDE Plasma Version: 5.22.4 KDE Frameworks Version: 5.85.0 KDE Applications Version: 21.08.0 Qt Version: 5.15.2 Graphics Platform: X11

(In reply to popov895 from comment #5) > openSUSE only? Yep, already fixed (https://bugzilla.opensuse.org/show_bug.cgi?id=1189687).
Fixed recently
Which commit?
This bug is still present as described by OP in Plasma 5.24.2 (frameworks 5.91.0, Qt 5.15.3). Two months ago, Harold Sitter said there was a fix, but no mention of which Plasma version.

In my experience, this bug is present on KDE Neon based on Ubuntu 20.04 but doesn't occur on latest Fedora version.
Yes, I am having the bug on KDE neon.

Issue still present in Kubuntu 22.04 : KDE Plasma 5.24.4 KDE Frameworks 5.92.2 Qt 5.15.3 Kernel 5.15.0-33
When dolphin is opened , after which you connect the device (for me Samsung Galaxy M32) , it shows "Could not access device. Make sure it is unlocked, and tap Allow on the popup on its screen. If that does not work, make sure MTP is enabled in its USB connection settings." . And after that even closing dolphin and reconnecting usb will not work , you have to restart the system , then connect usb then open dolphin to access android storage. Bug still persist for : Operating System: Arch Linux KDE Plasma Version: 5.26.4 KDE Frameworks Version: 5.101.0 Qt Version: 5.15.7 Kernel Version: 5.15.85-1-lts (64-bit)

Bug remains in kio-extras 22.08.2, Kubuntu 22.10, Plasma 5.25.5
The bug perisists. I am trying to access GrapheneOS on a Pixel 6 from Ubuntu 22.04 KDE/Plasma. During the troubleshooting process, at different times I've gotten both of the errors > No storage media found. Make sure your device is unblocked and has MTP enabled in its USB connection settings.` and > The file or folder udi=/org/kde/solid/udev/sys/devices/pci0000:00/0000:00:14.0/usb1/1-2 does not exist in Dolphin. I can confirm that if I close all running instances of Dolphin and wait for the system tray pop-up that appears when I plug the phone in, then the instance of Dolphin that starts when I click that pop-up is able to access the filesystem of the phone. That's not a long-term workaround, though. I have many ongoing projects at all times, and I need to have Dolphin windows open for most of them. It is not reasonable to have to go multiple workspaces to close and later re-open and re-navigate each window every time I need to exchange files with my phone. The `libusb` bug referenced in this [KDE bug](https://bugs.kde.org/show_bug.cgi?id=430606) on the topic and this [Mageia bug](https://bugs.mageia.org/show_bug.cgi?id=28216) was fixed in `libusb` v1.0.24; since my system (Ubuntu 22.04) has v1.0.25, it's most likely that the `libusb` bug is not the issue. Can anything be done? Ubuntu 22.04 KDE Plasma version: 5.24.7 KDE Frameworks version: 5.92.0 Qt version: 5.15.3 Kernel version: 6.2.0-37-generic (64-bit) Graphics Platform: X11 `kio-extras`: 4:21.12.3-0ubuntu1 `libusb-1.0_0`: 2:1.0.25-1ubuntu2 `libmtp9`: 1.1.19-1build1 `mtp-tools`: 1.1.19-1build1 `jmptfs`: 0.5-3
My workaround this bug:- When bug appear giving error message "Could not access device. Make sure it is unlocked, and tap Allow on the popup on its screen. If that does not work, make sure MTP is enabled in its USB connection settings." , first I open different folder in dolphin other than your MTP device folder, so I open click Home in Places of Dolphin. After that I open System Activity pressing Ctrl+esc , which shows System Activity window. Where I end the process called 'kiod5' , wait few seconds like 5 seconds or more. Then again click on the MTP device in dolphin , and I can easily access the storage of my smartphone.
Still appears in KDE 6. The workaround is if you have this error in Dolphin, on your Android phone popup change from "File transfer" to "Tethering" and back to "File transfer". It should appear in Dolphin
