Razer Junglecat tries to solve the mobile controller problem
It uses a Joy Con-like split design to attach to phones.

I've been reviewing hardware and software, devising testing methodology and handed out buying advice for what seems like forever; I'm currently absorbed by computers and gaming hardware, but previously spent many years concentrating on cameras. I've also volunteered with a cat rescue for over 15 years doing adoptions, designing marketing materials, managing volunteers and, of course, photographing cats.
The Junglecat puts control pads on either side of your phone and connects via Bluetooth. Initially, at least, it will only attach to specific models since it requires a special case that comes bundled with it: the Razer Phone 2 (natch), Samsung Galaxy S10 Plus and Galaxy Note 9 (plus the Huawei P30 Pro, which sells outside the US).
