Android Guides » Android devices » Get to know your mobile phone's components inside and out with these hardware apps

Any vez has Have you ever thought that, even if you know your camera's megapixels or RAM by heart, you don't really know everything that's inside your phone? These days, manufacturers publish fairly comprehensive technical specifications, but They only release a part of the movieMany hardware components and details are never mentioned... unless you use the right apps.

The good news is that, if you use Android (and to a lesser extent iOS), you have at your disposal a lot of applications that allow Dissecting the hardware and condition of your phone in detailWhat SoC does it have, who manufactures the camera sensor, what WiFi does it support, what temperature the CPU cores reach, or if the battery is starting to show signs of wear. And not only that: you can also test each component with guided tests to check its health.

Why is it worth knowing your mobile phone's hardware in depth?

Beyond geeky curiosity, keeping track of your mobile phone's components is useful for to really know what you've bought and how it performsOften, a manufacturer specifies a processor type but doesn't clarify the actual frequency, manufacturing technology, or exact GPU. The same applies to the screen, memory type, sensors, or battery.

With the apps we're about to see, you can check if your smartphone meets the minimum requirements from a demanding app or game, compare your mobile with other models before changing phones, diagnose hardware failures (screen, sensors, connectivity…) and even generate reports in HTML or PDF to send to technical support or a repair service.

CPU-Z is not perfect: sometimes may display incorrect data While it doesn't go into as much detail about camera modules as some other apps, it remains one of the best for identifying the processor and seeing how it performs core by core.

CPU-Z doesn't exist on iOS, but there are alternatives like AX-CPU For iPhone and iPad, focused on showing details about the processor and the rest of the hardware in a similar way.

Apps to test the health of your hardware: screen, sensors, and more

Knowing the components is good, but it's equally important to know if they're in good condition. That's where tools designed for this purpose come into play. physically test and diagnose each part of the mobile phone.

TestM: Guided check of basic components

TestME It's a very clear app for analyzing the status of your Android phone's most important components. It divides the hardware into six main categories and guides you through a series of very simple tests.

The categories it analyzes are:

• Screen: touchscreen and visual test to detect dead zones or response problems.
• SoundCheck speakers, headphones, microphone, and headset.
• Movement: gyroscope, accelerometer and compass tests.
• ConnectivityWiFi, Bluetooth, mobile network and GPS.
• Hardware: light sensor, charger, vibration, proximity sensor, fingerprint reader.
• Camera: front camera, rear camera and LED flash.

When you open it you can choose between one “rapid test” of the essential elements or a “full test” with about nineteen tests. Each test comes with on-screen instructions: touch certain areas of the screen, press physical buttons, bring your hand close to the front camera, activate Bluetooth, etc. You can always skip a specific test if you're not interested or can't do it at that moment.

As you complete tests, six circles at the top will fill up. When a category is fully verified, its circle will be completely filled and a green symbol will appear. Below, you can enter each group to repeat individual tests or run all the tests in that category using the "Verify Group" button.

In addition to diagnosis, TestM offers very useful extra features Accessible from the side menu: general phone information (storage, cameras, processor), IMEI and status (useful for knowing if a phone is locked or has been reported stolen), battery details, internet speed test, and, curiously, a map of nearby repair shops in case any test went wrong.

Other testing and benchmarking applications

If you want to push your phone to its limits and compare its performance with others, there are several tools designed for both pure benchmarking such as for testing specific components:

• AnTuTu, Geekbench, 3DMarkThese benchmarks measure CPU and GPU performance under various graphics and computing loads, then provide a score that you can compare with other devices. 3DMark, for example, focuses heavily on graphics performance, while PCMark is more geared towards real-world usage tasks and battery life.
• PCMarkIt evaluates performance in typical everyday tasks (browsing, editing documents, playing video, etc.) and can outlining autonomy with specific battery benchmarks.
• Test Your AndroidIt allows you to test screens, sensors, sound, and other elements, and also offers utilities such as a barcode scanner, sound meter, and flashlight. Its weaknesses are the ads and the fact that it doesn't generate structured reports after testing.
• Phone Doctor PlusIt diagnoses multiple sensors (GPS, CPU, 3G chip, gyroscope, accelerometer, etc.) and helps detect hardware problems, in addition to including tools for optimise the performance and battery life.

How to easily view your mobile phone's hardware on Android and iOS
