Back in 1986, Huey Lewis released his hit “Hip To Be Square.” But Google believes that it is now hip to be round, as in a circle. That is why it has changed some of the elements on the Gboard QWERTY keyboard app from squares to circles in Android 12.
And now, according to 9to5Google, the Alphabet subsidiary has made another change. With the “Popup on keypress” setting enabled, pressing on a letter will extend it out in a rectangular box. That is unless you’re running on Android 12 which changes the rectangle to a circle.
