OverMobile v1.2.0 Rebrand to OverBuild Labs

The app is now OverMobile by OverBuild Labs — matches the
website, OverManager desktop app, and OverMiner hardware line. Application
identity (applicationId), on-disk preferences, and the signing keypair
are unchanged: existing PoPMobile installs upgrade to OverMobile in place
with no loss of wallet, pool, pairing, or settings state.

Tag: v1.2.0
versionCode: 23
applicationId: com.proofofprints.kasminer (unchanged — v1.x installs upgrade in place)

Changed

• Brand → OverBuild Labs / OverMobile. Every user-facing surface — launcher label, splash, top bar, About card, settings, log copy/paste reports, notification text, OverManager pairing prose — now reads OverMobile / OverBuild Labs / OverManager / OverMiner.
• New launcher icon. Full adaptive + legacy + round set across all five densities, generated from the OverBuild hex/cube on a #0C0C0F background.
• OverBuild Labs palette. Emerald-500 primary (#10B981), violet-500 accent (#8B5CF6), neutral grey-black surfaces (#0C0C0F page, #16161B cards) — matches the website and OverManager. ~80 hardcoded Kaspa-teal / gold / navy color literals migrated alongside the Material3 colorScheme so the entire dashboard tracks the brand instead of just the Theme.
• Coin-agnostic logo. The in-app Kaspa hex (top bar, splash, About card) is replaced by the OverBuild hex — OverMobile is no longer visually locked to Kaspa as the SoC roadmap broadens.
• Dashboard typography polish. Card titles (SHARES / HASHES / THREADS / TEMP / BATTERY / THERMAL) move to a 10sp sans-serif with letter-spacing for a cleaner data-dashboard feel; values stay in monospace so digits + units line up across each row. HASHRATE value now white against the emerald label.
• Splash is single-phase. One 2-second hold of the OverBuild hex + white "OverMobile" wordmark, then into the dashboard. Company attribution moves to the About card.
• About card refreshed. support@overbuildlabs.com and https://www.overbuildlabs.com. Info button replaced with Material's Icons.Outlined.Info — crisp at every density.
• Worker name default for fresh installs is now OverMobile; existing installs keep their saved value.
• Device telemetry reports manufacturer="OverBuild Labs" to OverManager (was "Proof of Prints").
• Top bar fits on one line. Title shrunk to 15sp white monospace + 28dp icon so the OverBuild hex, wordmark, info button, Dashboard toggle, and Settings toggle all fit without wrapping.

Fixed

• THERMAL WARNING no longer clipped to WARNIN on narrow screens. Compact stat-card values drop to 16sp + ellipsis overflow so the longest labels fit cleanly.

Deferred to a later release

• GitHub repository URLs still point at github.com/proofofprints/... — the org has not been renamed yet.
• pool.proofofprints.com infrastructure unchanged.
• QR pairing wire-type identifier popmanager-register accepted as-is until OverManager flips to emit overmanager-register.

Notes

• applicationId, namespace, JNI symbol names, and on-disk SharedPreferences file names (kas_miner, popmanager) are unchanged. The rebrand is brand-only — protocol- and state-stable.

PoPMobile v1.1.1

First APK build of the 1.1 series. v1.1.0 was tagged but never published with
a binary, so this release rolls up everything that landed since v1.0.14.

Added

• Live (windowed) hashrate. The hashrate display now reflects what the
  device is actually doing right now (10-second window) instead of a lifetime
  average that smeared over throttling events. Stops decaying to a fixed value
  and hard-zeroes once mining is stopped.
• User-configurable thermal + power protection. Settings now exposes
  pause / resume temperatures, a battery cutoff %, "require charging" toggle,
  and an "external power mode" for plugged-in stationary use. Replaces the
  hard-coded 70 / 60 °C defaults.
• Protection-state banner. A coloured banner above Start / Stop says why
  mining is paused, throttled, or running with reduced protections (battery
  cutoff, unplugged, thermal critical, cooling, sensor unavailable, external-
  power mode, etc.) — instead of failing silently.
• Battery Saver detection. When Android's Battery Saver is on, the banner
  shows "Battery Saver active — OS throttling" so a sudden hashrate drop
  isn't mistaken for an app bug.
• Temperature + banner stay live when stopped. Hitting Stop no longer
  freezes the TEMP / BATTERY / banner readouts at their last values; the
  thermal poller keeps running.
• PoPManager pairing QR scanner. Scan a pairing code from PoPManager
  instead of typing it. ZXing is bundled in the APK — no Play Services
  dependency, works fully offline.
• In-app Thermal Diagnostics card (Settings → Thermal Diagnostics).
  Lists every thermal zone the OS exposes, the one protection is acting on,
  PowerManager headroom + thermal-status bucket, SoC model, and a
  "Copy report" button so users on unsupported chipsets can paste a clean
  bug-report into a GitHub issue.

Changed

• Thermal-zone selection broadened for non-Snapdragon devices. Public
  Android temp-monitor apps all read from /sys/class/thermal/, but their
  advantage is the breadth of zones they recognize. We now scan both
  /sys/class/thermal/ and /sys/devices/virtual/thermal/, recognize more
  CPU/SoC hint zone types, and explicitly skip trip-point zones (which
  return the trip threshold instead of the live temperature) and the
  Qualcomm PMIC soc zone (battery state-of-charge, not temperature).
  Non-Snapdragon phones that previously showed -- should now show a
  real temperature.
• Battery percent now matches the OS status bar. Reads
  EXTRA_LEVEL / EXTRA_SCALE from ACTION_BATTERY_CHANGED first, falls
  back to BatteryManager.BATTERY_PROPERTY_CAPACITY. Several OEMs return
  a smoothed, fast-charge-aware capacity that lags the real value by 5-10%,
  so the in-app reading disagreed with the system tray (e.g. 90 % in app
  vs 95 % in OS).
• Battery cutoff is honored while plugged in. Previously the cutoff
  applied only on battery; the user's "stop at X %" preference now applies
  on AC too, so the device still trips at the threshold when plugged in.
• Resume hard-capped below Pause. The Resume slider can no longer be
  set above the Pause threshold (would have caused the engine to immediately
  re-pause on resume). Thread count is also restored to the user's setting
  after a throttle event instead of staying clamped.
• PoPManager error parity. "Pairing code expired" message now matches
  PoPManager's canonical wording so support docs line up across both apps.

Fixed

• Stop-mining restart regression in statsUpdateLoop — Stop followed
  by Start would leave the engine wedged because of a race between the
  stats loop and onNewJob. The two paths are now decoupled.
• Thermal-pause race + unbounded pool reconnect. A pause that landed
  during a connection retry could spawn a second reconnect loop racing
  the first; both paths are now re-entrancy-guarded.
• Invisible CRITICAL thermal alert. The stats loop was reading a stale
  thermalState from a register because the field wasn't @Volatile, so
  CRITICAL transitions never made it onto the banner — users only ever saw
  "PAUSED — cooling" instead of the actual cause.
• kotlinx.coroutines.isActive import in the thermal poller — release
  builds were failing to resolve it on some toolchains.
• MiningEngine LinkageError on new JNI methods. Devices upgrading
  from older builds with cached native libraries no longer crash the stats
  loop when a JNI method signature changes; the loop swallows
  LinkageError and keeps running.
• Settings crash on rotation caused by an early return inside the
  diagnostics-card composable.
• Slider integer truncation (thread count, temperature thresholds)
  was rounding to whole values mid-drag, plus a Compose hover-state crash
  on long-press of the slider thumb. Both fixed.

Notes

• versionCode 22, versionName 1.1.1, applicationId com.proofofprints.kasminer (unchanged — v1.0.x installs upgrade in place).
• v1.1.0's tag is left as-is for history; this release supersedes it.

PoPMiner v1.1.0

PoPMobile v1.1.0

First minor release since v1.0.10. Brings full thermal and battery
protection with a live status banner, PoPManager auto-discovery on
the LAN, and a pool client that recovers on its own when the bridge
bounces.

What's new

Thermal protection

User-configurable warn / throttle / pause thresholds with a separate
resume target. Auto-throttles to half threads on THROTTLE, auto-pauses
on CRITICAL, and auto-resumes after a 30-second sustained cooldown.

The status banner above Start/Stop tells you exactly why mining is
paused — distinguishes thermal critical, low battery, unplugged, and
cooling-after-pause, so you don't have to guess.

Battery & external-power modes

Battery-cutoff percentage is configurable, with optional "require
charging to mine". External power mode is for CellHasher / bench-PSU
/ battery-bypassed rigs — skips battery checks entirely so a phone
running off external 5V doesn't pause itself when Android reports
0% battery

PoPManager integration

• mDNS auto-discovery — PoPMobile finds your local PoPManager on the
  LAN; no manual IP entry needed.
• Telemetry continues reporting while mining is stopped, so the
  device stays visible in PoPManager between sessions.
• Remote start / stop / set-threads / set-config commands honored.
• QR-code pairing scanner is built in, ready for the upcoming
  PoPManager release that will display the pairing codes.

Reliability

• Pool reconnect retries forever (with exponential backoff capped at
  60 s) instead of giving up after ~7 minutes. If your stratum bridge
  goes down for an hour and comes back, the miner reconnects on its
  own — no Stop/Start needed.
• Single-press Stop now actually stops mining. A race between the
  stats-update loop and the StratumClient could previously re-start
  the engine immediately after stop, requiring a second press.
• THROTTLE actually reduces thread count. The same race used to
  re-start at full thread count even after a "reducing to N threads"
  log line.
• CRITICAL pause is no longer racy — once the threshold is crossed,
  mining stops and stays stopped until the resume threshold is met.

UI polish

• Landscape scrolling fixed.
• Numeric formatting forced to Locale.US so hashrate / temperature
  display correctly in non-US locales.
• Banner uses severity colors (red for CRITICAL, amber for WARNING,
  blue for INFO).

Upgrading from v1.0.10

Seamless in-place upgrade. Settings, logs, and PoPManager pairing
are preserved.

PoPMobile v1.1.0-rc1

⚠️ Release candidate — manual install only. The in-app updater
ignores pre-releases. Please report any issues you hit before we
promote this to v1.1.0 stable.

Focus areas to validate: CRITICAL thermal pause actually stops
mining; THROTTLE drops to half threads and stays there;
single-press Stop works; pool auto-reconnects when the bridge
bounces; mDNS discovery finds PoPManager on your LAN.

PoPMobile v1.0.10

Stacks the pipeline-verification version bump on top of the v1.0.9 progress-bar fix so a single merge brings both changes to main.

Commits

• 13c11ab — v1.0.9 progress-bar fix (from PR #16): replace Material3 LinearProgressIndicator with a plain Box to sidestep the KeyframesSpec version mismatch that crashed Download
• 158fbce — v1.0.10 version bump: versionCode 10 → 11, versionName "1.0.9" → "1.0.10", CHANGELOG entry

No functional changes beyond what's already in PR #16.

Why a second version for verification

The v1.0.9 builds were smoke-tested by Claude and built/installed by the maintainer, but the in-app Check for updates → Download → install path has never actually been exercised against a real newer release (every previous attempt hit the progress-bar crash before reaching install). v1.0.10 exists to give a v1.0.9 device something newer to find.

Test plan

• ./gradlew assembleRelease builds cleanly
• Signed APK fingerprint matches 6c849abe…
• Device running v1.0.9 → Settings → About → Check for updates → offers v1.0.10 → Download → progress bar renders + fills (no crash) → install screen appears → install → app reopens as v1.0.10
• Settings, logs, PoPManager pairing all preserved

Supersedes

Closes #16 — this PR contains all of it.

PoPMobile v1.0.9

v1.0.7 misdiagnosed the Download-button crash as an R8 issue. The NoSuchMethodError still reproduced with minification disabled on the emulator this session, ruling that theory out.

Root cause

compose-bom 2024.01.00 ships material3 1.1.2 and animation-core 1.6.0 together. Material3's LinearProgressIndicator internally calls KeyframesSpecConfig.at(Object, Int) (new 1.6 generic signature), but the bundled animation-core doesn't expose that overload — producing:

java.lang.NoSuchMethodError: No virtual method at(Ljava/lang/Object;I)
    Landroidx/compose/animation/core/KeyframesSpec$KeyframeEntity;
  at androidx.compose.material3.ProgressIndicatorKt$LinearProgressIndicator
  at com.proofofprints.popmobile.update.UpdateDialogKt.DownloadingBody

…the first time DownloadingBody tried to render after the user tapped Download.

Fix

Replace LinearProgressIndicator with a plain Box we draw ourselves. No KeyframesSpec, no internal animation, nothing to version-drift against. Visually identical (6 dp tall, rounded 3 dp, cyan fill on dark track), ~15 lines of code.

Version

versionCode 8 → 10 (skipping 9 to keep the broken v1.0.8 interim artifact distinguishable), versionName 1.0.7 → 1.0.9.

Test plan

• ./gradlew assembleRelease builds cleanly
• Signed APK fingerprint matches 6c849abe…
• Emulator on v1.0.7 → Settings → About → Check for updates → offers v1.0.9 → Download → progress bar fills (no crash) → install screen appears → install → app reopens as v1.0.9

PoPMobile v1.0.1

Internal Kotlin package rename from kasminer to popmobile. Upgrades in place — no settings loss, no re-pairing required.

PoPMobile v1.0.0

PoPMobile v1.0.0

First public release of PoPMobile — a Kaspa kHeavyHash miner for Android with optional PoPManager integration for remote monitoring and control.

Low hashrate expected on mobile devices. Do not expect meaningful profit — treat it as lottery-style mining.

Install

Download popmobile-v1.0.0.apk below, transfer it to your Android device, and tap to install. You may need to allow "Install unknown apps" for your browser or file manager in Android Settings.

Requires Android 8.0 (API 26) or newer. Tested on emulator and TCL A3X; please open an issue if something misbehaves on your device.

Highlights

• Native kHeavyHash miner (arm64-v8a, armeabi-v7a, x86_64) ported from the KASDeck ESP32 reference
• Stratum v1 client with extranonce support, 10 s connect timeout, and cancellable retry loop
• Rich pool status UX — specific error reasons (REFUSED, TIMED OUT, DNS FAILED, UNREACHABLE, NO NETWORK) instead of a generic offline badge
• Thermal monitoring + auto-throttle — pauses mining when the device gets too hot
• Live dashboard with hashrate, shares (accepted / rejected), hash total, thread count, temp, battery, and thermal state
• QR code scanning for the Kaspa wallet address (bundled ZXing, no Play Services dependency); handles bare, kaspa:kaspa:…, and ?amount=… URI forms
• Foreground service keeps mining running in the background with a persistent notification and one-tap Stop
• Mining log showing the last 4 hours of stratum + share events
• PoPManager integration — pair once with a 6-digit code; telemetry every 30 s; remote commands (set_config, set_threads, start, stop, restart) applied and acknowledged

Configure

Open Settings after first launch:

Field	Example
Pool URL	stratum+tcp://pool.proofofprints.com:5558
Wallet	kaspa:qyp… — paste or scan QR
Worker Name	any label (defaults to PoPMobile)
Threads	how many CPU cores to mine on

Tap SAVE, then START MINING.

To connect to PoPManager, open Settings → PoPManager Integration, enter your server URL (http://host:8787), a device name, and the 6-digit pairing code from the PoPManager dashboard.

Full docs: README.

Known limitations

• Verified on Android emulator and TCL A3X only — other Android versions and OEM skins have not been exhaustively tested
• Play Store distribution is not available (Google prohibits on-device crypto mining apps); sideload the APK or use Obtainium / F-Droid
