The DroidDeck Android app lets a recent Snapdragon phone run Steam in Big Picture mode and play Windows PC games locally, with no cloud streaming and no root. It’s free, it’s early, and it only works on certain chips.
Here’s the short version before the details:
- It’s a free, open-source project you install from GitHub, not from the Play Store.
- You need an Adreno 730 GPU or newer (Snapdragon 8 Gen 1 class and up).
- 9to5Google recommends 12GB of RAM or more and UFS 4.0 storage.
- Pixels, Exynos Galaxy phones and other Mali-based phones aren’t supported.
- Heat and battery drain are the biggest limits, so plan on a controller.
What DroidDeck Android actually does
DroidDeck boots Valve’s Big Picture interface on your phone and runs games through ARM64 Proton, with FEX translating x86 code. Games install to your phone’s storage and run offline.
According to 9to5Google’s hands-on, cloud saves, backups and Workshop content carry over from your Steam account. Per PCGuide, you can also add GOG, Epic and Amazon games as non-Steam titles. Version 0.3.2 lets Steam downloads keep going while the phone sleeps.
Which phones can run it
The GPU decides everything here. This table sums up what the two reports say about chip support.
| GPU / Phone type | Status | Notes |
|---|---|---|
| Adreno 730 or newer (including 8xx) | Supported | Newer chips run smoother |
| Adreno 6xx | Experimental | Expect problems |
| Adreno 710, Mali, Xclipse, PowerVR | Not supported | Covers many mid-range and Exynos phones |
| Recent Google Pixels | Not listed | 9to5Google found none on the compatible list |
Android 9 or newer is the software floor. In practice, your hardware is the real gate. The 9to5Google reviewer tested on a Galaxy S25 Ultra and named the OnePlus 12 as a value pick.
How setup works
You don’t need a terminal or root. Based on 9to5Google’s walkthrough, the steps look like this:
- Download the APK from the project’s official GitHub page.
- Sign in with your Steam account.
- In settings, pick a Proton layer and turn on the Mesa Turnip graphics drivers.
- Install a game and launch it, ideally with a controller connected.
The Turnip step matters, because it’s what gives Adreno GPUs 3D acceleration.
What performance looks like on a phone
Results swing a lot by game and by phone. These are single-tester numbers, not benchmarks you can count on.
| Game | Phone tested | Reported result |
|---|---|---|
| Portal 2 | Galaxy S25 Ultra | Locked 60fps at 1080p |
| Batman: Arkham Knight | Galaxy S25 Ultra | About 30-40fps at 720p, with sharp drops |
| Cyberpunk 2077 | Galaxy S25 Ultra | Failed to launch |
| Cyberpunk 2077 | REDMAGIC 11 Pro (per PCGuide) | About 60fps at medium settings |
| Left 4 Dead 2 | REDMAGIC 11 Pro (per PCGuide) | Hit the 120fps cap at 720p |
The Cyberpunk split tells the story. A gaming phone with a Snapdragon 8 Elite Gen 5 and 16GB of RAM handled it, while a Galaxy S25 Ultra couldn’t start it. Older, lighter games are your safest bet.
Why Android PC gaming is picking up now
DroidDeck isn’t alone. In a Nov. 3 newsletter, 9to5Google’s Daniel Bader said Android gaming is in “a very good place,” citing console ports, stronger hardware and community tools.
Other projects, like WinNative and an Android branch of nxnative, take different routes to the same goal. Bader also notes that AI coding tools have helped some of this progress.
The open question is reliability. If you spend more time fixing settings than playing, the novelty wears off fast. That’s the real test for DroidDeck over the next few releases.
The catches to know before you install
Phones aren’t built to run PC games for hours. The 9to5Google review flagged thermal throttling from the lack of active cooling, and demanding games can drain a full battery in under an hour.
Storage is the other squeeze. PC games are big, and they install to internal storage, so a 256GB phone fills up fast.
There’s also the sideloading question. The 9to5Google piece doesn’t name the developers, so only grab the APK from the official GitHub page and keep Google’s scanner on. Our post on the Play Protect reminder explains why that’s worth doing.
Frequently Asked Questions
Is DroidDeck free?
Yes. The app is a free download, and 9to5Google calls it an open-source project. You still need to own the games in your Steam library.
Do I need to root my phone?
No. 9to5Google says it runs without root, ROMs or cloud streaming. You install the APK and sign in to Steam.
Does DroidDeck work on a Pixel or Exynos Galaxy phone?
Not right now. Mali and Xclipse GPUs are listed as unsupported, and 9to5Google found no recent Pixel on the compatible list.
Can it run Cyberpunk 2077 on Android?
It depends on the phone. One tester reported about 60fps on a REDMAGIC 11 Pro, while 9to5Google’s Galaxy S25 Ultra couldn’t launch it.
Is DroidDeck better than a cloud gaming service?
It works offline and needs no fast connection, but it’s rougher and hotter. Cloud services take the strain off your phone, so they suit demanding titles better.
If you own a Snapdragon 8 Elite phone and a controller, DroidDeck is worth an afternoon, especially for older Steam favorites you already own. If your phone has a Mali or Xclipse chip, skip it for now. Treat it as a fun experiment, not a replacement for a Steam Deck or a gaming laptop.
