Ease of pushing the upper button on the screen using one hand

Ease of typing in letters using the keybord funtion

If you aren't being careful it is really easy to mistype when using the "vivo X21i (2018) 128GB" with two hands since the buttons are so small. In addition, typing at high speeds is pretty difficult and I can't say its very suited for it.
