The 7 Best Android Apps to Check What's Wrong With Your Phone
Your smartphone has a vast amount of components inside. If one of these components isn't working correctly, it can ruin your whole experience.
But how do you pinpoint exactly what is wrong with your device? Maybe the accelerometer seems a bit off, or web browsing on mobile data or Wi-Fi feels sluggish. How about if you bought a secondhand Android device and want to check that everything works OK?
Whatever the problem, there's an app that will help you figure out what's wrong with your Android phone. Even if you don't have a specific problem, it's good to run a smartphone checkup to make sure everything is ticking along nicely.
1. Phone Check and Test
Phone Check and Test is one of the best Android hardware checking apps you can get. The app functions somewhat like the desktop app CPU-Z, giving you a complete rundown of your phone's hardware specifics while adding an extensive range of hardware check options.
The hardware checking options include:
- Low memory check and suggestions
- Battery check and charging socket test
- Wi-Fi and radio check
- Audio tests for speakers, microphones, headphone jack, and volume buttons
- Display tests, such as dead pixels and color consistency
- GPS tracking and location testing
- Thermal stress
- CPU, memory, and storage stress checks
Thankfully, the app is straightforward to use. The Monitor option provides a basic overview of your current phone status, including CPU load, battery charge, overall health, and your current network connections.
You then have the Guided Test menu, a section that lets you run a series of tests. Head down the list and select the checks and tests you want (that relate to your smartphone issue), or leave everything turned on for a full system-wide check. (We've shown more ways to fix an Android device that won't turn on.)
The Phone Check app suggests turning on Wi-Fi, Bluetooth, and NFC, making sure you have at least 30 percent battery, and conducting the test using battery power (rather than your power outlet). When you're ready, hit the Test Phone button and watch the Android smartphone testing magic unfold.

2. Phone Doctor Plus
Phone Doctor Plus is like a little trip to the doctor... but for your phone. The app allows you to run through a series of system hardware checkups to ensure every bit of your phone is working properly.
The tests between Phone Doctor Plus and Phone Check are relatively similar, but the Phone Doctor Plus UI provides a better overall experience. At least, it does visually. Under the hood, using a Samsung Galaxy and an old OnePlus phone for testing, all the results were similar.
Phone Doctor Plus has 30 or so hardware tests for your Android smartphone, such as:
- Movement sensors, including gyroscopes, accelerometer, and proximity sensors
- Display tests, including dead pixels and touchscreen responsiveness
- Cellular and network connection tests
- Humidity, pressure, and temperature sensor tests
- Memory, storage, and CPU benchmarking
Phone Doctor Plus certainly makes it easy to test your device. The star ratings quickly illustrate any issues or alert you to something that's about to turn into an issue. The battery health check is also handy, offering suggestions for the best ways to improve and recalibrate your battery.

3. Dead Pixels Test and Fix
The two preceding apps find dead pixels but don't fix them afterward. If Phone Doctor Plus or Phone Check does show a dead pixel or two, you can move on to the Dead Pixels Test and Fix app.
This free app runs a similar scan to the other Android troubleshooting apps, identifying any dead pixels. Some stuck pixels are hardware defects and can't be fixed by any app. However, others need to cycle through their three options (red, green, and blue) enough times to refresh them.
(We've shown ways to fix a stuck pixel on any screen if you'd like to test this on other devices.)
Dead Pixels Test and Fix attempts to repair partial sub-pixel defects, stuck sub-pixels, dead pixels, dark and bright dot defects, and phantom images. The process can take anywhere between a few minutes to over an hour to run. The developer advises that if you don't see any improvement within a few hours, the app, unfortunately, won't be able to fix your issue.

Battery life and degradation are some of the most infuriating aspects of owning a mobile device. Your battery seems to be working fine one moment, then the next it crashes with a 25 percent charge remaining. There's a reason for that: batteries have a limited life, and the overwhelming majority of us don't maintain those batteries efficiently.
The AccuBattery app doesn't magically fix your battery problems. If your battery is dead, no app can help it. However, AccuBattery does run through a list of specific battery health checks in an attempt to figure out where your battery is in its lifecycle.
The app features useful information such as the current battery capacity versus the intended capacity (and thus, the level of wear). You'll also learn how much wear your battery sustains with each charge and how much power each app uses, along with the overall discharge speed.

5. Repair System for Android
Repair System for Android is an app with tons of features like a junk files cleaner, CPU cooler, phone booster, game booster, antivirus, and more. Most of these features fix issues with your phone, but the app's two main highlights in terms of diagnosing what's wrong with your phone are Repair System and Hardware Check.
Repair System checks your entire system for issues and repairs the detected problems in your phone's system. It also fixes errors related to the boot, file system, and RAM.
The Hardware Checker included in the app checks the basic hardware of your phone and indicates which parts are working properly and which need fixing.

6. Test Your Android
As the name suggests, the Test Your Android app tests various components of your Android device. The app is divided into Utilities and Tools, Device Information, Hardware Testing, and Sensor Testing.
Utilities and Tools, and Device Information provide you with many useful features and info regarding your device that are worth checking out. But Hardware Testing and Sensor Testing are the ones related to your phone's health check.
Hardware Testing lets you test the monitor color, multi-touch feature, camera, speaker, fingerprint, and more. Each test helps you detect problems with your phone's hardware.
Sensor Testing tests various sensors, including light, temperature, pressure, compass, and many more. After testing, it lets you know if the sensor is working properly.

Sensors is a toolbox with an all-in-one diagnostic tool that keeps you updated about everything related to your mobile device's sensors.
The app tests your phone's accelerometer, geomagnetic field, orientation, gyroscope, light, gravity, and whatever other sensors it has. The tests are visible through figures as well as live plotting and graphs. It supports almost all the sensors an Android device can have.
In addition, this app can also test your battery, date and time, camera (both front and back), and other hardware and system-related components. With Sensors, you will have your physics laboratory with you on your phone.

Android Health Checkup Complete
These apps represent some of the best free options for you to conduct a free Android health check. There are a substantial number of apps on the Play Store that claim to check, fix, update, and clean your Android device. The vast majority aren't necessarily bad apps but are clones of existing projects, offering little innovation or an expansive toolset.
So, try out one of the apps mentioned above to check the condition of your smartphone.
