Integrated Android diagnostics and professional software for used mobile phones
It's not all about installing an app from Google Play. Many manufacturers integrate hidden or pre-installed diagnostic tools which allow you to test hardware without resorting to third parties, something especially interesting if you want official tests or if an operator has limited access to certain functions.
Diagnostic codes and hidden menus in Android
Some phones include hidden menus accessible from the phone app. On several Samsung Galaxy models, for example, you can try dialing * # 0 * # Tap the dial to open a comprehensive diagnostic menu with tests for the screen, sensors, vibration, speakers, etc. From there, you can tap on each specific test and verify if the component is responding correctly.
It is good to know that Some operators disable these menus or they change their behavior, and in certain countries they are not available by default. If the code doesn't work, the usual course of action is to use a diagnostic app or consult with the carrier or the manufacturer's official support.
Device Help and diagnostics in Motorola
Many Motorola phones come with The Device Help app is pre-installed.which includes a "Device Diagnostics" section. From there you can run tests dedicated to battery, audio, camera, connectivity (WiFi, mobile data, Bluetooth) and touchscreen.
The app also integrates a more comprehensive hardware diagnostic To check sensors like the proximity sensor or cameras, and even run a full phone test from the Hardware section. It's a very convenient way to check the phone's status without installing anything extra.
Diagnostic options for Google Pixel
In the case of Pixel phones, access to diagnostics It varies depending on the model and Android version.In some cases, codes similar to *#0*# can be used for internal menus, but when they don't work, Google offers support through the Pixel help community.
In that self-help flow you can Enter your Google email and IMEI from the device and follow diagnostic instructions or troubleshooting guides. You can find the IMEI in Settings > About phone or on the device box or SIM tray.
HwMM Test on Huawei Mobiles
Huawei devices integrate a system app called HwMMITestIt's designed for guided hardware testing. To access it, go to Settings > Applications, enable the option to show system apps, and then search for HwMMTest.

It has gained a lot of importance in the professional environment of buying and selling used mobile phones. Phonechecka diagnostic and certification solution geared towards wholesalers, shops and technical servicesUnlike "user" apps, Phonecheck offers an automated scan of more than 80 checkpoints that checks audio, battery, cameras, GPS, LCD screen, connectivity, sensors, NFC, etc.
One of the most important functions of this type of software is the verification of component authenticityIt indicates whether the screen, cameras, battery, or motherboard are OEM (original equipment manufacturer) or aftermarket parts. This is crucial because non-OEM parts reduce value, can void warranties, and often offer lower quality.
Phonecheck generates complete device history reports including brand, model, IMEI, status in databases of lost or stolen mobile phones, outstanding debts, operator blocking, production and sale dates, warranty status and, when known, repair history.
It also certifies that the phone is Fully functional, securely erased and restored (with ADISA-certified erasure), unlocked and ready to activate. The results are uploaded to the cloud, can be exported as PDFs, and even printed as labels to place on the phone itself, which helps justify the price and builds trust with the buyer.
Benchmark tools: measuring the real power of the hardware
Beyond looking at the specifications, many users want Measure the actual performance of CPU, GPU, RAM, and storageThis is where the benchmark applications, which launch intensive workloads to compare your mobile phone with other models and see if it performs as it should for its range.
Antutu Benchmark: historical benchmark for global performance
Antutu It's one of the best-known names in mobile benchmarking. It offers comprehensive or customized tests for CPU, GPU, RAM, UX (user experience) and IO (storage)Its performance index breaks down scores for single-core and multi-core CPUs, as well as graphics and memory performance.
The total score, by itself, serves little purpose beyond guidance, but it is very useful for Compare your smartphone to other modelsFor example, a phone with 20.000 points should perform roughly twice as well as one with 10.000 in the same test. Antutu maintains leaderboards with results from numerous phones so you can see how yours stacks up against the competition.
Geekbench 5: CPU analysis and real workload
Geekbench 5 has become the standard for measuring CPU power in single and multi-coreIt subjects the processor to intensive and light tasks that simulate real-world workloads. It generates a score for single-core and another for multi-core performance, helping to understand how the phone performs in everyday use and under heavy multitasking.
The app also includes Compute BenchmarkGeekbench is a module that evaluates the device's graphics capabilities through APIs such as OpenCL, CUDA, or Metal (depending on the platform). Geekbench is cross-platform, so you can... Compare an Android to an iPhone, a PC, or a Mac.It also displays details of the CPU (name, cores, frequencies), device model, motherboard, and other technical data.
3DMark: GPU-intensive graphics tests
3DMark It is more focused on graphics and GPU performanceespecially in gaming contexts. It includes several tests, including Wild Life, Wild Life Extreme, and Sling Shot/Sling Shot Extreme, which apply different graphical loads to measure performance and stability.
Wildlife offers a balanced load representative of current gamesWith options for a quick benchmark or a prolonged stress test to simulate long sessions, Wild Life Extreme significantly increases the workload and is designed for high-end devices, where it's often difficult to exceed 15 FPS. Sling Shot and its Extreme variant are useful for comparing older or mid-range phones.
The app is free and no adsIt also generates graphs, rankings, and scores that let you see how well your device holds up under load, how it responds to system updates, and whether it's up to the standard you expect for demanding games.
GFXBench Benchmark: Advanced GPU and Battery Analysis
GFXBench It is another very powerful tool for Evaluate GPU performance, long-term stability, rendering quality, and power consumptionIt offers a wide variety of tests, many of them with cross-API support between Vulkan and OpenGL.
Among its best-known tests are Aztec Ruins, Car Chase, Manhattan 3.1, Manhattan, T-Rex or synthetic tests such as ALU, Texturing, Driver Overhead, Fill Rate, etc. Aztec Ruins, for example, simulates workloads similar to modern games with dynamic global illumination, HDR, real-time shadows, and SSAO.
GFXBench also includes battery and stability tests to see how performance degrades over time and how much power the GPU consumes during testing. It also has a section to compare results with other devices and an information section listing the smartphone's graphics capabilities.
PCMark for Android: Real-world task performance
PCMark It adopts a different approach: instead of focusing on synthetic loads, it uses tasks based on real-world applications and APIsIt does not measure CPU, GPU and storage as isolated elements, but the system as a whole, simulating how the phone behaves in everyday use.
The proof Job 3.0 It tests the device in web browsing, video editing, typing, data manipulation, and photo editing, providing a score that better reflects performance in real-world scenarios. In addition, PCMark includes hardware monitoring during testing, useful for seeing how the load is distributed or how the manufacturer manages thermal throttling.
Another of its star features is the battery life test under real workloadsThis is very useful if you want to compare how many hours your phone lasts against others with similar usage.
Other useful benchmark apps
In addition to the above, there are several other interesting tools for measure specific aspects of the hardware:
- PassMark: lightweight suite with CPU, disk, memory, 2D and 3D graphics tests, with an online database to compare scores and a CPU-Z style device specifications section.
- Disk SpeedFocused on storage performance, it allows you to measure read and write speeds on internal, external, USB or custom paths, with test size control for more reliable results.

It includes 46 tests across 14 sections and can leverage NPUs and AI accelerators in SoCs like Snapdragon, Exynos, Kirin, or Dimensity, as well as supporting proprietary TensorFlow Lite models in PRO mode.
Additional popular benchmarks and memory monitoring apps
There are other applications that, while not purely hardware information applications, are often used for Check actual specifications and performance of an Android versus other models.
Geekbench, Antutu Benchmark and CPU X in everyday use
we have already mentioned Geekbench and Antutu as key benchmarks, but it is worth emphasizing that many specialized websites and users use them for Verify if the mobile phone you are going to buy performs as the manufacturer promises.Both have rankings and lists that make it easy to compare your device with the one you have in mind.
On the other hand, CPUX It's an app that combines hardware information (speed, cores, RAM, camera, sensors) with practical utilities such as monitoring internet speed, battery temperature and amperage, technology news and a test panel for microphone, Bluetooth, headphones, volume, flashlight, etc.
CPU X also includes widgets, ruler, spirit level, compass and emergency signal, offering a curious mix between a device information center and a toolbox for everyday use.
RAM Booster and memory tools (and why to be careful)
Some applications like RAM booster They focus on showing the total physical and virtual RAM capacity, the percentage of free memory and offer functions to automatically free up memory when a certain user-configured threshold is reached.
Although these tools allow you to view memory data at a glance and have a very simple interface, it's worth remembering that The latest versions of Android manage RAM very well on their own. And aggressive "boosters" can actually worsen performance by closing processes that the system will reopen a few seconds later. In any case, they can be useful for visualizing the actual amount of RAM the device has.
Memory tests and tools that don't work on Android
In some comparisons or lists of hardware tools they appear classic PC programs which are not compatible with Android, but are mentioned for their historical relevance in diagnosis.
MemTest86: great RAM tool, but only on PC
MemTest86 is a renowned RAM memory diagnostic program for computersIt is capable of performing multiple test runs and detecting faults in defective modules, even those with large capacities (up to 64 GB of RAM or more in current versions). It operates autonomously, booting from USB on both 32-bit and 64-bit systems.
Although it is easy to use and the results are relatively simple to interpret, This tool is not available for Androidso it is only sometimes mentioned as a comparative reference of what can be done on PC but not on mobile.
HWiNFO: Comprehensive hardware analysis in Windows and DOS
Another utility that often appears in listings is HWiNFO (Hardware Info)a very complete software of Hardware monitoring and analysis for Windows and DOSIt provides detailed information on CPU, motherboard, monitor, audio, network and many other components, with real-time monitoring and powerful reporting options.
However, currently There is no working version of HWiNFO for AndroidFor that type of in-depth analysis on mobile devices, we need to use the specific Android apps that we have been reviewing throughout the article.
