My phone screen is broken but I managed to finally tap the allow button for ADB authorization so I can access the device via ADB.

My question:
Is there a way to do this once and never be asked again or backup the RSA which I can then push to the device via ADB if it happens to need re-authorization again (since I have a broken screen I just can't tap allow again).

I have enabled do not ask again on this device, but that does not seem to work from past experience and it keeps asking me to authorize if I reboot the phone.

    Does this answer your question? "Allow USB debugging" keeps on popping evene when "Always allow from this computer" is checked in automation testing

  • @alecxs But scrcpy depends on adb for uploading the file that is executed. Hence it can't be used to control the phone before adb authorization has been set. But afterwards it would be also by preferred way to control a phone with a broken screen.

  • @alecxs Hey thanks for the links, the second one kinda helped but not really, I managed to backup the keys and use scrcpy but then it just disconnected in a second and now we are back to adb authorization prompt even though I had authorised it an hour ago. :(

  • Though I had managed to get apowermirror/tea,viewer working but none of those let me unlock the device, it just shows a black screen sadly.
