Hello, i had the same problem, my device (Fujitsu F01J) cant connect to PC, the app in PC detect my device as (FO1J). I have activate the usb debugging, but the apps in pc says “Failed to connect” every the loading bar reach 27%. any solutions? Thanks. PS. In the other apps (Android Studio) my device is detected as “Unknown Device” is the problem is in my phone?
My problem is as follows, when I plug the usb cable from the phone to the PC, the window does not appear on the screen of the phone to allow USB debugging that you allow the digital RSA printing of the computer, making usb connectivity impossible.Note, I’ve already enabled USB debugging in Developer mode.does anyone have any solution for this ???.
