Device Info: CPU & System 앱 분석 (10월 1일)

Device Info shows you what's actually inside your Android phone - CPU, RAM, battery, storage, sensors, network, installed apps - and lets you test the hardware to check it all still works. Useful if you're a developer, doing QA, checking a used phone before you hand over money, or you just want to know which chip you're running. DEVICE AND HARDWARE - CPU - model, architecture, core count, live per-core clock speeds - GPU - renderer, vendor, Vulkan support - RAM - total, used, available, plus kernel counters like ZRAM, swap and cached - Storage - internal usage, partitions, mounted volumes - Display - resolution, density, refresh rate - Battery - level, health, temperature, voltage, technology, charging status - Cameras - every camera the device exposes, with resolution and capabilities - Sensors - vendor, range, resolution and power draw for each one - Thermal, audio and network hardware SYSTEM - Android version, API level, codename, security patch - Build details, bootloader, kernel, build fingerprint - SELinux and Treble status - Runtime, locale, uptime HARDWARE TESTS Run these before you trust a phone. Handy when you're buying or selling one. - Display test with full-screen colour patterns - Multi-touch - Microphone, speaker, ear speaker - Vibration - Camera and flashlight - Power button and volume buttons - NFC, Bluetooth, Wi-Fi, network - GPS and location - Charging - Fingerprint sensor WI-FI ANALYZER Scan what's around you and find a clearer channel. - Signal strength in dBm with a live meter - Band, channel, channel width, security type - Router vendor lookup and rough distance estimate - Channel graph with a per-channel congestion strip - Recommendations for 2.4 GHz and 5 GHz DATA USAGE - Per-app usage for today, 7 days or 30 days - Mobile and Wi-Fi kept separate - Foreground vs background split - System apps grouped honestly, so nothing gets counted twice FLOATING MONITOR Draggable tiles that stay on screen over other apps - FPS, RAM, battery, network, storage. Keeps running while you're gaming or doing anything else. APPS AND PRIVACY - Installed apps explorer - version, size, install date, target SDK, install source - App Analyzer - your installed apps broken down by store, target SDK, min SDK, last updated and size - Permission Insights - flip it around and see which apps hold a given permission, filtered by High, Medium or Low risk - Security scanner that flags risky app capabilities - Search and filtering across everything installed WIDGETS AND LIVE MONITORING Six home screen widgets: RAM Quick Look, Device Summary, Battery, Storage, CPU and Battery Temperature, Network. - Sensor Lab for real-time sensor graphs - Live battery, memory and network monitoring DEVICE REPORT Export the whole thing as a PDF - hardware, system, battery, network. Good for support tickets, resale listings and bug reports. Light and dark themes follow your system setting.
