the block list.

pharmacies that use robocalls to communicate important information 
to you. Robocall uses an autodialer to deliver pre-recorded messages. 
By entering the name of the organizations into the star name list, it 
ensures these calls will ring through when you only know the caller 
names but not their numbers.

Notes:
 Once you have activated the remote voice control feature, you are using 
your cell phone’s voice app to operate your cell phone.
  Please check the cell phone user’s manual and the voice app’s help 
topics to nd out what commands you can use and any limitations of 
the voice app.
  Some cell phone manufacturers or network carriers may customize the 
phone’s operating system and implement their own voice app. If you 
want to use Google Now, you need to manually set it as your default 
voice app. For detailed instructions, refer to your cell phone user’s 
manual, or contact your cell phone’s manufacturer or network carrier. 
You may also go to “Google Product Forums” on the Internet and check 
the corresponding help topics.
  Due to the settings of certain cell phones and voice apps, your cell 
phone may not support the remote voice control feature. Contact your 
cell phone’s manufacturer or network carrier, or check the voice app’s 
help topics if you encounter any problems.
  During the remote voice control activation, if your Android cell phone 
comes with both a dedicated voice app and Google Now, it may prompt 
you to select which voice app to use, and whether use it for just once 
or always. Select the desired options. If you do not respond to your cell 
phone’s prompt in time, the handset screen will return to idle, and the 
 icon will disappear. You can restart by following Steps 1-3 mentioned 
above.
  If you receive a landline or cell line incoming call when you have 
activated remote voice control on a connected cell phone, the remote 
voice control operation will be ended.
  The feature may be ended automatically by your cell phone. For 
example, a cell call has been established via the remote voice control 
feature and the call has just ended.
 If you need to press dialing keys (0-9, TONE , QUIET#) during a cell 
call, please make the call using the cell lines of your telephone system 
instead of using the voice app via the remote voice control feature.
