An always-on dashboard for the Samsung Galaxy Z Flip 3 cover screen — it turns a phone with a dead main display into a 1.9" monitor that never sleeps: phone sensors, server health, token prices, weather, and incoming notifications.

Everything is configured from a browser on another machine; you never have to arrange anything on the tiny screen itself — in Indonesian or English, page and phone together.

Screenshots

Pages rotate on a timer; these are four of them, straight off the cover screen. All are 512 × 260 — the whole panel — and all use the pixel style with the everforest palette, which is one of 4 × 12 combinations (see Themes).

zeroserver — a Linux box scraped over the network through node_exporter: CPU, RAM, SoC temperature, disk, uptime. See Monitoring other servers.	dunia — weather from Open-Meteo, crypto prices, and a clock widget spanning two cells.
pasar — the Jakarta Composite index from Yahoo as a candle widget. The timeframe in the corner (1j × 32 — 32 hourly candles) is derived from the data's own timestamps, not hand-written.	token — the same widget pointed at a Binance pair on a 4-hour timeframe. Both were installed from the Chart token tab without writing any config.

The dashboard is configured from a settings page the phone serves itself on port 8099 — screenshots of every tab.

Why it exists

This Z Flip 3's main screen is broken; all that's left is the 1.9" cover screen. The phone itself is perfectly healthy — Snapdragon 888, rooted, and already earning its keep as a small server (AdGuard Home, Uptime Kuma, Tailscale exit node). Rather than let it die, that little screen became an always-on monitor — no dependencies (just Canvas, org.json and HttpURLConnection, ~2.9 MB APK), configured entirely over the network.

Use cases

What you want	How
Monitor a home server	A shell/http source against node_exporter — see Monitoring other servers
Clock + weather + room temperature	A clock widget, an Open-Meteo source, and the light/pressure sensors
Crypto & stock ticker board	Token charts: Binance, Indodax (IDR), Bitget, Bybit, OKX, Yahoo
Service up/down board	An http source in prom format against Uptime Kuma + the status widget
A notification board	ntfy.sh — messages chime and take over the screen
The phone's own health	Built-in metrics: battery, CPU, RAM, network, storage, Wi-Fi, SoC temperature
Anything with an API	An http source plus a JSON path, or shell when the data needs massaging

A single JSON file is the source of truth. The settings page only ever writes that file; the phone watches it for changes and redraws without restarting.

Quick start

Needs a rooted Z Flip 3 (Android 12+), JDK 17 and the Android SDK — full list in Install.

git clone <repo> flipdash && cd flipdash
echo "sdk.dir=$HOME/Library/Android/sdk" > local.properties     # adjust to taste
cp .fdrc.example .fdrc                     # adb serial & phone IP, or leave both blank
./fd deploy                                # build + install + launch on the cover screen
./fd ui                                    # open the settings page in a browser
