Phone Farm Hardware for Game QA: Parallel Sessions on Real Android Boards

**Why emulators fall short** GPU drivers, touch latency, background process limits and carrier-specific behavior differ on real boards. **Lab setup** Motherboard boxes reduce power and heat vs full phones while keeping real SoC behavior. Batch launch, screen mirror and log capture via group-control software. **Parallel sessions** Run compatibility matrices across Android versions simultaneously — one operator supervises 60–100 nodes from stacked boxes. **Network testing** OTG/LAN mode isolates device segments for regional IP or latency simulation when combined with VPN per node.
