10月21日的Secret Codes & Phone Test应用程序分析

Secret Codes & Phone Test puts every useful Android dialer code and a complete hardware test kit in one small app. Open a code with one tap, see exactly what your phone is made of, and check that the screen, sensors, camera, speaker and battery all work. It is the quickest way to test a phone you already own or one you are about to buy second-hand. SECRET CODES, ONE TAP AWAY • Dialer codes (the *#…# kind) sorted by what they do: IMEI, service menu, hardware test menu, network and SIM settings, software version • Brand collections for Samsung, Xiaomi, Tecno, Infinix, Oppo, Vivo, Huawei, LG and more • Tap to dial, or copy the code to your dialer • Search any code or feature in seconds DEVICE INFO, COMPLETE • Model, manufacturer, board and build number • Android version and security patch • CPU, RAM, storage, display and camera details • SIM, operator, signal and Wi-Fi information • IMEI and serial number check HARDWARE TESTS • Touchscreen and dead-pixel test • Proximity, accelerometer, gyroscope, compass and light sensors • Camera, flashlight, speaker, microphone and vibration • Bluetooth, Wi-Fi and GPS checks • Fingerprint sensor support BATTERY AND PERFORMANCE • Battery health, temperature, voltage and charging status • Live RAM and storage usage • CPU details and performance overview CHECKING A USED PHONE? Run the display, touch, sensor, camera, audio and battery tests in a few minutes, confirm the IMEI matches the box, and read the exact model and Android version before you pay. WHAT THIS APP DOES NOT DO It does not unlock, root, reset or bypass anything. Dialer codes open menus that your phone's manufacturer built in, and they vary by brand, model, Android version, region and carrier, so some codes will not work on some phones. Use codes that change settings with care. Fast, lightweight, works offline for device info and tests, no account needed.
