DeepCheck: Hardware Test

DeepCheck is a hardware test and full diagnostics tool for your phone: a CPU stress test, a GPU test, RAM and internal storage speed tests, detailed device info, and 24 separate tests — one per component. Everything runs offline, with no ads and no data collection.

Start with the load tests: a few minutes show how the phone holds up under load and whether it throttles. The individual checks are there when you need to be sure about one specific component — the screen, a sensor, the camera, connectivity.

⚡ CPU STRESS TEST
• A native C++ engine loads every core at once
• Live readings: temperature, core clocks, GFLOPS, performance drop and the system thermal status
• Three load profiles: combined, FPU and memory
• Duration, thread count and core selection are all configurable

🎮 GPU TEST
• GPU compute performance in GFLOPS
• FPS across three 3D scenes: pixels, geometry, textures
• Watch the frame rate drop as the GPU heats up
• GPU model, vendor and OpenGL ES version

🧠 RAM TEST
• Write, read and copy speed
• Memory latency
• Automatic memory type detection: LPDDR3…LPDDR5X

💽 STORAGE TEST
• Sequential read and write
• Random read and write
• The real speed of the built-in storage, not the spec sheet number
