Do you have to use two hands to send text messages on a touch-screen mobile phone?

It depends on what kind of touch-screen mobile phone and what kind of input method are used. I have played many touch-screen machines, and I feel that typing is not slower than that with buttons, and certainly slower than qwerty keyboard. The virtual keyboard of the touch screen is also the same as the ordinary nine squares, and abc is together, such as the built-in input method of the Nokia Fifth Edition machine, and so is the point message. There are also full keyboards, and I don't think it's convenient to write by hand. If it's a nine-square keyboard, you can play it with one hand. After all, each key is relatively large. The touch era is coming. Go and buy a full touch screen with capacitors. Personally, I like touch screens very much. Thank you.
