You don't need to buy hardware to get one-tap control of your stream. A phone on a stand next to your keyboard, running a deck, handles scene changes, mic mute and "be right back" just as well — and you already own it. This guide covers the buttons worth making, how to wire them to OBS without plugins, and the practical bits: mounting, power and keeping the screen awake.
Step 1: give OBS actions hotkeys
The most reliable way to control OBS Studio (or Streamlabs Desktop) from any deck is through hotkeys. In OBS, open Settings → Hotkeys and assign combinations you'll never press by accident — for example Ctrl+Alt+Shift+1 for your first scene. Assign hotkeys for:
- Each scene you switch to (Starting soon, Game, Just chatting, BRB, Ending)
- Mute/unmute microphone and mute/unmute desktop audio
- Start/stop streaming and start/stop recording
- Save replay buffer (if you use it for clips)
Tip: OBS hotkeys work while OBS isn't the focused window, so pressing a deck button during a game won't pull you out of it.
Step 2: build a streaming page
A layout that works on a phone held in portrait (3 columns):
| Starting soon | Game | Just chatting |
| BRB | Mute mic | Mute desktop |
| Clip it (replay buffer) | Discord mute | Ending |
| Go live | Record | Open chat |
Put the buttons you press mid-game (mute, BRB, clip) where your thumb rests, and the rare, risky ones (Go live, Ending) in a corner. Short labels double as voice commands in SofaDeck — "press BRB" works when your hands are on the controller.
Step 3: macros for the big moments
With multi-step macros (SofaDeck Pro, or any deck with macro support) one tap can do a whole routine: switch to "Starting soon", unmute the mic, start the stream and open your chat pop-out. Build an "End stream" macro in reverse. Add short waits between steps so OBS has time to switch scenes before the next action.
Step 4: mount and power the phone
- A weighted desk phone stand keeps it upright at a readable angle; a clamp arm frees desk space and can put the phone right beside your monitor.
- Keep it charging — a short right-angle USB-C cable stays tidy on a stand.
- Turn up auto-lock while it's on the charger (iPhone: Settings → Display & Brightness → Auto-Lock; Android: Display → Screen timeout), or use the phone's "stay awake while charging" developer option.
- Turn on Do Not Disturb so notifications don't cover your buttons mid-stream.

Step 5: rehearse
Do a private test stream (or record locally) and press every button once. Check that audio mutes where you expect, that scene hotkeys don't collide with game controls, and that the phone reconnects after you lock and unlock it. Five minutes of testing saves a panicked live moment.
Phone deck or hardware?
If you end up relying on the deck every stream, physical keys are nicer to hit without looking. Our macro pad vs phone deck guide covers when it's worth buying hardware, and our Stream Deck alternatives comparison lists the other phone apps.
Frequently asked questions
Can a phone replace a Stream Deck for streaming?
For most streamers, yes — scene switching, mic mute, starting and stopping, and chat macros all work from a phone deck. The trade-offs are no tactile keys and a phone that has to stay awake and charged. Many streamers use a phone deck first and buy hardware later.
How do I control OBS from my phone?
The simplest way is to give each OBS action a hotkey in OBS Settings → Hotkeys, then put those hotkeys on buttons in your phone deck. It works with any deck app and doesn't require plugins.
Will using my phone as a deck affect my stream's performance?
A button deck sends tiny messages over your local network, so it has no measurable impact on encoding or bandwidth. Screen-streaming remote desktop apps are heavier — avoid those while live.
