- The device page on a phone now shows metric graphs, not only the current numbers. CPU, memory, temperature and every health sensor the board reports — fan speed, PSU voltage, power consumption — over 1h, 6h, 24h, 7d or 30d, the same history the desktop shows.
- Tap CPU, RAM or Temperature to chart it. Sensors without a tile are one tap away in the row of chips above the graph. Devices with no samples yet show no empty card.
