Vivo mobile phone is safe. What if the pedometer turns on the black screen and there is no response?

Hello, I'm sorry for the trouble. It can be handled in the following ways: 1. When there is a problem that the running program is blank and unresponsive, you can first press the Home button to try to return to the desktop, then pull up/down the shortcut bar and click again to speed up the cleaning and closing of the background program; 2. Then go to Settings-More Settings-Application-Installed-find the pedometer software of Dr. Ping An, and clear the data before using it; 3. If this happens while running the repair software, it is recommended that you uninstall the software and reinstall it, or replace it with another version.
