Droid Explorer cannot find device As the title implies, Droid Explorer cannot detect my Samsung Galaxy Tab A.
I've enabled USB debugging and set up Droid Explorer with Android SDK Platform-Tools 28.0.1.
I can detect the device with adb devices which shows:

5200dfccec4a940d    device


I can send commands to it as well, running adb reboot will cause the device to reboot, but Droid Explorer still cannot detect it.
Droid Explorer is pretty old and unmaintained for years.

Some years ago Google changed the API of adb. If you are using a recent version of adb together with Droid Explorer which was developed for the old adb version this may end up in several non-functional features.

You should better check for an adb based tool that is still actively developed and maintained.
