I sure didn’t, but it seems that many Android phones have built-in solutions instead of awkwardly trying to hold the phone and trying to hit the white dot at the same time.
Many phones have the capability to take voice commands, so if you fancy that, go into the camera app and play with the settings. But if you ever held a real camera in your life (which means you are old), you might like shooting with the volume down button better.
Go ahead, try it. Go into the camera app and press the volume down button. Did it work? If not, I feel your pain. But if it did, from now on you can aim with your phone like with a camera and probably taking selfies will be much easier too.
