Which is better, a square mobile phone or a round mobile phone?

It is recommended that it be round and feel good, unlike the square hand, which is easy to separate.

It is very helpful for the protection of mobile phones from bumping and falling. The contact area of rounded cell phone in the corner is much larger than that of right-angle cell phone, which is safer for the protection of cell phone frame and screen. Just like this, portable devices rarely have right angles. For example, Apple phones have always been round.
