Apple does not want us to use other browsers, for this reason Safari works as default app on iOS devices when opening any link. But Google has decided to put Apple in check and in its new update of the Google + application for iOS it has moved from Safari and allows its users to open links in Google Chrome.
Of course, this option only works if we have downloaded the google browser on our device. This is indicated in the information published in the App Store:
"Post web links now open in Chrome (if installed)."
This could be the first step for Google, since it could apply the same option to all its applications for iOS. What if the other developers followed in your footsteps? How will Apple take this action that could end its browser dominance?
