FAQ

The questions people actually ask.

What's a good score?+
For 2025–2026 flagships, expect 700 000–1 000 000+ on Standard mode. Mid-range (SD 7 Gen 3 / Tensor G3 / Exynos 1380 class) lands 250 000–400 000. Older or budget devices sit at 100 000 and below. The Pixel 8 Pro reference is exactly 284 917.
Why is my GPU score lower than I expected?+
Fast&Fast measures the OpenGL ES 3.x pipeline running real shaders. Phones with strong Vulkan-only acceleration paths may score below their published gaming-bench numbers. The fillrate test uses a 96-iter Mandelbrot fragment shader that’s very ALU-bound, so memory-bandwidth-tuned GPUs benefit less than they would in a textured-quad fillrate.
My NPU scores are weirdly low.+
Your device needs to expose NNAPI delegate support. Some recent phones (notably Samsung Exynos in late 2025) ship inconsistent NNAPI drivers that silently fall back to CPU; you’ll see roughly 50× lower NPU scores when that happens. The bench gracefully runs anyway and reports what it measured.
Can I run the bench multiple times in a row?+
Yes — try Stress test mode (5 runs back-to-back with a 10 s cooldown between each). You get a sustained-performance percentage showing exactly how much your device throttles when it gets hot.
Can I delete a run from the leaderboard?+
Yes. Email feedback@fastandfast.com with the Run ID (the XXXX-XXXX identifier visible in the URL or on the Results screen) and we’ll purge it.
Why is the bench shorter on my device than on my friend's?+
Bench mode differs. Settings → Bench mode defaults to Standard. Quick uses ¼ iterations (~20 s total), Long uses 3× (~3 min, good for throttling observation). Quick and Long runs are stored locally but never submitted to the public leaderboard.
Does it work on WSA or Android Emulator?+
It runs, yes. But the emulated OpenGL stack and sensors don’t represent any real device, so the scores are meaningless and submissions are auto-disabled. You’ll see a warning banner on the Home screen when an emulator is detected.
Why HMAC signing?+
Without it, anyone with curl could spam the leaderboard with fake scores. The ClientKey is shipped per-APK-version; if a bad actor extracts one key, we revoke exactly that key — not a continual cat-and-mouse game with rotating client secrets.
I have a Pixel 8 Pro, why is my score not exactly 284 917?+
The baseline was set from a representative P8P sample, not yours. Your specific unit varies by roughly ±10% depending on thermal headroom and DVFS state. The leaderboard’s median per-device score is the closest thing to a “real” reference — currently around 312 000 for Pixel 9 Pro and 350 000 for Galaxy S24 Ultra.
Can I export my run data?+
Not yet — it’s coming in a later version. For now, your local runs are visible on the History screen and individual run URLs (https://fastandfast.com/r/XXXX-XXXX) are permanent and shareable.
How do I install on a phone without the Play Store?+
See /download — install the signed APK from GitHub Releases. Step-by-step instructions are on that page.
