• Improved Gestures: The new gesture navigation system is more intuitive and feels more natural compared to the previous version.
• Smart Lock: The smart lock feature is more responsive and accurate, making it easier to unlock the device.
• Better Performance: Android 10 brings several under-the-hood performance improvements, which I've noticed in daily use.

• Boot and stability: Successful boot to home screen, sustained uptime without spontaneous reboots, and crash logs (logcat) free of recurring fatal exceptions.
• Kernel and driver logs: dmesg and binder logs for errors related to GPU, Wi‑Fi, Bluetooth, modem, and audio subsystems.
• Performance benchmarks: IPC/IO latency, CPU throttling behavior, and GPU throughput to check for regressions.
• Power profile: Screen-on and idle power consumption measurements before and after update, plus wakelock analysis.
• Connectivity: Wi‑Fi and Bluetooth pairing stability, cellular signal/handovers (if applicable), and throughput across bands.
• Permissions and storage: App behavior under scoped storage and updated permission prompts; verify file access for typical apps.
• Security patch level: Confirm the included Android security patch level and any backported vendor fixes.
