Button to allow ADB backup not working I have a Oneplus One running CyanogenMod 12.0. (Based on Lollipop 5.0) I'm trying to create a backup using ADB. I executed the command, and it gave me the usual prompt to unlock my phone and allow the backup. On my phone, the screen comes up asking me if I want to encrypt the backup with a password, and with the "Do not back up" and "Back up my data" buttons. So far so good.

The "Do not back up" button works fine: When I click it, the command on my computer stops running. But the Confirm button just does nothing. When I tap the button, nothing happens; the button doesn't even "light up" like buttons normally do.


The button is not "grayed out" or disabled: It looks exactly like the other, functioning, cancel button.
I tried inputting a password, thinking maybe it would not allow me to back up my data unencrypted, but it still behaved exactly the same
I tried running the "adb backup" command with literally every combination of arguments, with the same results
"adb devices" does show my phone properly connected


How can I either


Fix this, and make an ADB backup
Make a complete backup in some other way, without root access. (I want to unlock my bootloader, which wipes all data)
For me force stopping the Facebook Messenger seemed to fix the problem.
In your case it might be related to a different app.

Go to Settings->Apps->Select the application you suspect->Press "FORCE STOP"

Possibly this is related to the "draw over other apps" privilege.
