Changing android password remotely I have Nexus 4 with Android 5.1.1, lock with a PIN code.
Somehow the right 3 vertical dots don't response for touch, therefore I can't unlock my phone.

I want to cancel / change the password.


I don't have root
I don't remember if the Debug Mode is turn on or not, but my computer usually recognize the phone just after I unlock it - just connecting the USB do nothing.
In addition, the command "adb devices" show nothing.
Inserting 5 times the wrong password just locking me out, without giving me the "Forgot Password" option.
Using the "Lock" option of the Android Device Manager put black shade on the screen with a chosen lock message, but I can't find the place to enter the new lock password I chose. I only see the 2 soft keys (circle and triangle) and when I touch them the screen move to the regular lock screen with the PIN code... [See Edit]


I'll appreciate any help!

Thanks in advance.

EDIT:
When I try to set new password through the Android Device Manager (ADM), after 2 seconds the website says: "Since Google has verified that a screen lock is already set, the password you entered won't be needed.", it's mean that my new password that I chose will not set, and that the reason I couldn't use it from the first place. Still looking for help!
It might be a bit late but I had a similar issue and found a genius idea that might help others.

If you have an OTG cable, you can plug in a mouse and use that to unlock the phone, then cancel / change it as you normally would.

Hope this helps!
