How do I turn my phone into a Steam Deck for my PC games?

You want a handheld for the games you already own, without buying a second machine to install them all again. The phone in your pocket has a better screen than most handhelds; what it lacks is a way to play your PC library on it properly.

The apps you try get close and then miss: black bars because the PC does not render the phone’s shape, a clip-on pad that turns into a generic controller, a stream that only works on your own Wi-Fi, and a session that dies when you walk from one room to another.

And every one of them asks for something — a router rule, an account, a PIN typed on the PC each time.

A handheld experience is four things at once: a full-screen picture at the phone’s exact resolution, controls the game recognises, a link that works wherever the phone is, and a session that survives the phone changing networks. Most streaming clients solve one or two of them and leave the rest to you.

Under the hood the picture is an H.264 or HEVC stream decoded by the phone’s hardware decoder, the pad is a USB device plugged into the phone, and the link is either your home network or a direct path opened through a meeting point. Getting all four right is what separates a toy from a handheld.

1. 01

   Install ChimpDeck on the phone and the host on the PC

   Android 8.0 or later with a hardware H.264/HEVC decoder on the phone; Windows 10/11 with an NVIDIA graphics card for the host. One installer on the PC, no admin prompts afterwards.

2. 02

   Pair once, at home, without a PIN

   Open the PC page on the phone while both are on the home network; confirm the six-digit number the PC shows. Mark the phone as trusted so it can reach the PC from anywhere later.

3. 03

   Clip the pad on over USB

   A USB clip-on pad reaches Windows as the real device, rumble included. A Bluetooth pad works too, as a virtual Xbox 360 controller, though today it does not vibrate (Bluetooth rumble is coming soon). Not sure the sticks are healthy? Run the drift test first.

4. 04

   Let the PC take the phone’s shape

   At pairing the host learned your phone’s size — 3216×1440, 2412×1080, whatever it is — and serves it on a virtual display, so no black bars and nothing stretched. Your monitor comes back when you stop.

5. 05

   Add your games

   On the PC, add games or launchers with box art and they appear in the phone’s list; the Desktop is always there. Games can be closed when the session ends.

6. 06

   Take it out of the house

   On 4G, 5G or hotel Wi-Fi the app finds the PC through the meeting point and opens a direct path — no port forwarding, no VPN, no account. Quality adapts live, and a drop pauses the session instead of ending it.

• Your whole library, not a subset

  It is your PC: every launcher, every mod, every save, at PC settings.

• The phone’s native resolution

  Learned at pairing, served the same session, edge to edge.

• A pad the game recognises

  Over USB, the actual device with its official driver and four rumble motors.

• Play anywhere

  Home Wi-Fi, 4G, 5G or a hotel, with a session that reconnects by itself.
