A new way of user interacting with the phone I just change from my old Samsung S7 phone to the new Google Pixel 5 phone. The fingerprint recognizer is placed behind the phone instead of the front home button. It is so much convenient, as I donât need to use another hand to turn it on. However, to use it, I still need to use another finger to touch and swipe it. This defeats the purpose of a single hand to unlock the phone. But you can use your thumb to swipe it⦠Yes, some user use their thumb to scroll up and down some news content. A single hand is possible with the thumb. â¦
