So, today in this post I will be telling you about a way with the help of which you will be able to clock any of the user available in your Google GMail contacts from the chat feature right from your iPhone. Obviously this can be done using the web application service of Google Talk available on the browser on iPhone but let me tell you that you can do this with the help of Hangout application on your iPhone. Steps are really simple and I will be telling you how to do this, step-by-step.
Now open any chat on the Hangout application and tap the highlighted option on the screen to see further list of options.
On this screen you will see the option in red color button to block the particular user. Once you block any user from here, he/she will not bother you even on Google Talk application and Google Chat available on the left of GMail Inbox.
The blocked users will be synced throughout your Google Account whether it is Google Hangout Google Talk or GMail. Similarly as mentioned above in the screenshot you will also have the option to switch off the chat history so anytime when you will chat with this particular user it will always be off the record. Please let us know if you want to know more about the feature related to Google Hangout or any other application on iPhone.
