Hi I want to screencopy Samsung J7(that flashed custom rom before and enabled usb debugging before screen crack)

However It keeps showing ADB device with blank result. Troubleshooting a lot, search and reverse search what is ADB and even install these

Results I get when I connect OPPO A31 with USB DEBUGGING ON. I even uninstall one drive as youtube mention path variable/environment variable messed up programming background.

Sorry to say if I missed out anything please let me know I am willing to even record a video.

Start with the linked scrcpy FAQ section on device detection and compare it with the reported ADB results for the Samsung J7 and OPPO A31. Reproduce the connection symptoms and determine whether the issue is specific to scrcpy or to ADB/device setup; done means the cause and next troubleshooting step are documented.
