Created attachment 135565 [details] A GPX file copied over KDE Connect SUMMARY Files copied from Android device to PC using Dolphin → devices → <devicename> → place in directory tree, have their file contents mashed up. The file starts normal, then after 32KiB restarts, and the last 32KiB is missing. This seems to be highly reproducible. STEPS TO REPRODUCE I have KDE Connect set up on my pc, phone, and tablet. 1. On my pc, I open Dolphin, and under "Devices" go to "IIVQphone", or "kdeconnect://6148fde336752e14/". 2. I then navigate to the appropriate folder, in this case "/run/user/1000/6148fde336752e14/SD card/Android/data/net.osmand.plus/files/tracks/rec/" 3. I copy a GPX file over to my PC OBSERVED RESULT 4. Any GPX-accepting application complains GPX is malformed 5. Upon opening, I see the GPX looks like attached "2021-01-26_14-06_Tue_copied_over_KDE_Connect.gpx". The file content is exactly the same size as on device, but "restarts" after 32KiB. The last 32KiB of the source file are missing. 6. This happens with other files copied too, both on SD card and on device itself. EXPECTED RESULT Files copied are copied byte-for-byte as on device SOFTWARE/OS VERSIONS Computer Linux/KDE Plasma: Kubuntu 20.04 KDE Plasma Version: 5.18.5 KDE Frameworks Version: 5.68.0 Qt Version: 5.12.8 KDEconnect-app: v1.0 KDEconnect-cli: v1.4.0 KDEconnect-handler: v1.4.0 Phone: Moto G5 Plus (XT1685) Android 8.1.0 Kernel 3.18.71-perf-g7b625a0 KDE connect 1.16.0 Tablet: Lenovo TB-8504X Android 8.1.0 Kernel 3.18.71 KDE connect 1.14.2 (originally) ADDITIONAL INFORMATION I tried the same, copying files from my tablet which had KDE connect 1.14.2. Here the files did not restart. When I updated this to KDE connect 1.16.0, it had the same bug. It seems to have appeared between 1.14.2 and 1.16.0.
Someone else has a problem that might or might not have been the same bug, see https://forum.kde.org/viewtopic.php?f=18&t=169649&p=442762#p442762
To clarify: I tested this with a few GPX files, a few JPG files and a few .3GP files. They all had the same problem, repeating the start after exactly 32768 byte and having their last 32768 byte truncated.
