Seems like something that would do well in China, if for no other reason than that mobile games are super prevalent and Tencent and Timi already manage a hugely popular one--still, I already find MOBAs like Honour of Kings unpleasant to control on a phone, a shooter like PUBG is definitely not something I want to play on a screen that small or with controls that bad.
Without knowing how it actually works, the biggest problems are pretty clear:
-Awareness is fairly important in PUBG, whether it be sound or sight. Seeing far off into the distance, let alone aiming, is going to be hard unless there's just heavy aim assist or something.
-If your fingers are all over the screen to aim and to control the character, it's not going to be super easy to see what you're doing anyway.
Put on top of this the fact that it's on a big map with 100 people and I just can't imagine it, unless you were to do as someone posted above and set the phone down with a mouse and keyboard peripheral, but that kind of defeats the point of playing on a phone in the first place.
