Forgotten the pattern and phone not showing the "forgot pattern" button. I upgraded my Moto G2 to Android Lollipop using over-the-air upgrade. It was awesome but I set a pattern lock which I forgot. Usually after 5 wrong attempts it shows the "forgot password" button but it is not showing that button even after 100 wrong attempts. How to unlock the phone?
Well, I would say I don’t think you can’t do anything about it because the forgot password button isn’t available with the Lollipop , now what you are left with is you can try unlocking your device with the help of your Google account i.e. Log yourself over the Google account you are using over Laptop/PC once done head over to the Android device manager  and using it try unlocking your device remotely, also in order to do that your device must be connected to the Mobile  Data or Wi-Fi network. And if you don't have the access then I guess you are locked out and the only thing you can do now is factory resetting your device by holding the Power+Volume down button.
