Check How to Run Diagnostics on an iPhone or Android Device

Maybe you ran into some issues and need to fix them. Or maybe you’re looking to sell or give away your device and want to make sure it’s in good condition. Whatever the reason, you can run diagnostics on your phone with a handy app called TestM. Developed for iOS and Android, TestM can run diagnostic tests to check display, sound, camera, connectivity, and other features. You can run a comprehensive test that checks all supported features. You can run a quick test to check just a few key components. You can run tests for a specific group.

your camera or your connectivity. And you can only test one feature. Many tests are interactive, requiring you to take a selfie, listen to audio, or touch specific areas of the screen. Once the test is complete, the app will present you with a status report indicating any issues. You can share this report via email, messaging or any other service. And although the application is intended for mobile phones, it is compatible with the iPad. The only downside is that being a free app, TestM regularly throws ads at you, so you have to deal with them.

android

Most Android phones have simple diagnostic tools hidden within the operating system, but they vary by device. The tools are found by typing codes into your phone’s app dialer, much like entering cheat codes in a video game. Type the codes below and the menus should open automatically.

These are the two main codes that can be used on most Android devices:

*#0*# hidden diagnostic menu:

Some Android phones come with a full diagnostics menu. You will be able to perform a review of at least some of the phone’s hardware. However, this code is not available on all phones; nothing happened when I tried the code on a Pixel XL, for example, although the menu appeared on a Samsung Galaxy S9. For those who have access to it, this is a useful tip. The menu offers a series of independent tests to check the performance of different parts of your phone, such as the screen (touch recognition, color accuracy), cameras, sensor, and physical buttons such as power controls and of volume.

*#*#4636#*#* usage information menu:

This menu will appear on more devices than the hidden diagnostics menu, but the information shared will be different between devices. At a minimum, you should be able to view the app’s usage history; real-time Wi-Fi and cellular network connection statistics; and basic phone information such as current service provider, phone number, etc.

You don’t need to press the call button or anything else to open the hidden menus, they just open automatically. If nothing happens when you enter the code, your phone does not have this feature. Likewise, some devices don’t provide much useful information, like the aforementioned Google Pixel (which relies on Google to collect diagnostic information from your phone in the background). If so, skip to the next section for recommendations on third-party diagnostic apps.

Phone check and test (Android)

Phone Check and Test is a simple app, but it does more than just check that your phone’s hardware “works.” A full scan includes comprehensive CPU, memory, and battery diagnostics, and the test metrics are very detailed. This makes Phone Check and Test a bit less user-friendly than TestM, but it’s a great troubleshooting tool that gives you tons of data.

The free version has ads, but they’re minimal and you can upgrade to Plus for just $2 to remove them. The Plus version also adds a few more test tools and lets you run separate tests for each piece of hardware separately, saving you time on a full system scan.

iPhone

Apple is known for its products as “walled gardens”, which makes it difficult for users to do DIY reviews and fixes for their devices. Unsurprisingly, you won’t find any built-in diagnostic tests that you can run on an iPhone.

That said, iPhone settings include detailed readings on performance and battery history. To find this data, go to Settings > Battery.

Running diagnostic scans

With limited options available in iOS, the only real option for running diagnostics on your iPhone or iPad is to use a third-party app. These apps are also useful for Android phones that don’t have built-in diagnostic tools, or if you want a more detailed (and less cumbersome) way to test your phone’s hardware.
