Only Android devices will do. iOS allows neither opening an extra display nor installing the same application twice.
2. Prepare the phone
1. Unlock the developer options
Tap seven times in a row on “Build number”. A message confirms that you are a developer. The exact path for your brand is further down.
2. Turn on debugging
Turn on “USB debugging”. To play without a cable, turn on “Wireless debugging”.
3. Connect the phone
By cable
Plug in the cable, then accept the request on the phone and tick “Always allow”. It then shows up in DT Hub on its own.
It does not work?
Unlock the phone: the request only shows on an unlocked screen.
Try another cable: many only charge.
In the phone's USB notification, try “File transfer”.
Developer options: “Revoke USB debugging authorisations”, then plug it back in.
Wireless
Wireless debugging › Pair device with pairing code. Type the six-digit code it shows into DT Hub. The PC and the phone must be on the same Wi-Fi, with Android 11 at least.
In DT Hub: “Pair a new device”, then follow the window.
It does not work?
To pair, keep the code screen open on the phone: it only shows itself to the PC meanwhile.
After a restart, turn “Wireless debugging” back on: the pairing is kept.
Box with two Wi-Fi networks (2.4 and 5 GHz): keep the phone on one, wireless debugging turns off when it switches.
The PC and the phone on the same Wi-Fi, not on the router's guest Wi-Fi.
Windows: the network set to “Private” (Settings › Network & internet).
Windows firewall: allow “Android Debug Bridge” on Private and Public.
Turn off the PC's VPN, if there is one.
As a last resort: “Type the address by hand”, in the pairing window.
4. A second account on the same phone
Each account lives in its own Android profile, with its own copy of the game. Two ways to add one:
From DT Hub: the + button on the phone's row, then “Clone the game”. Creates a new Android profile on the phone, with its own copy of the game, for one more account. The game will ask again for its resources and the login.
From the phone: its brand's cloning feature, detailed below.
