Blackberry phones, like any other phones, may start having issues after using them for a while.
When your bb Z20 stops working properly and you need to use it urgently, then it becomes necessary to hard reset the phone.
Hard resetting is a term used to mean erasing all information and data from a mobile device.
As a result, you could lose your necessary data. It is hence necessary that you back up any important data in your laptop, cloud backup, or google drive before hard resetting your BlackBerry Z20.
If you can remove the battery in your Z20 do it first. Some user says after that phone works well again.
Open the battery cover of your smartphone and remove its battery.
Press and hold the Power key for no more than ten seconds.
Put the battery back, close the cover and turn the phone back on.

How to soft reset blackberry Z20 by button combination
Press and hold together Vol- and Vol+ and Power buttons.
If this combination is not working try Vol- + Power or Vol+ and Power or Vol- + Vol + at least for 10 seconds or some change.
This reset does not remove any data it’s like restarting and using it when your phone freeze or is unresponsive.
If you forgot your password On BB Z20 some users say that you need to type the wrong password “blackberry” a few times and your phone will be reset. (I am not sure if this will work with the new BB OS)
