Tricks to Diagnostic Your Android

If you’ve never run a diagnostic test on your own smartphone, it’s worth it— especially if your phone starts showing its age, or if you’ve bought a second-hand “new” smartphone and want to get a feel for its condition.

Especially diagnostic tools are useful if your device becomes less effective but you can’t pin down why. Instead of using guesswork to troubleshoot the different features on your phone before you come on a solution, a diagnostic scan will show exactly what’s wrong with your phone, or at least provide enough information to guide you in the right direction.

Unfortunately, it can be difficult to find the built-in diagnostic tools on Android smartphones and iPhones, and some devices don’t even have very good diagnostic options to get started (if at all). However, you can always turn to third party apps for help.

Built-in diagnostics tools

  • Android

Most Android phones have a few simple diagnostic tools hidden in the OS, but they vary between devices. You can find the tools by typing codes into the dialer of your phone app — kinda like inputting cheat codes in a video game. Enter the codes below and the menus should be opened.

Here are the two codes which can be used on most Android devices:

*#0*# Menu hidden diagnostics: Some Android phones have a full diagnostics menu. You will be able to perform a check-up for at least some hardware on the phone. This code is not available on all phones though — nothing happened, for example, when I tested the code on a Pixel XL, though the menu appeared on a Samsung Galaxy S9. It’s a handy trick for those who do have access. The menu includes many separate tests to check the output of the various parts of your handset, such as your screen (touch recognition, color accuracy), your cameras, sensor and physical buttons, such as power and volume controls.

#*#4636 #*#* Usage Information Menu: This menu will appear on more devices than the hidden Diagnostics menu, but the information shared between devices will be different. At the very least, you should be able to see the history of app use; the stats of real-time wifi and cellular network connection; and basic phone information such as the current service carrier, phone number, etc.

This specific code allows you to easily diagnose your device, but some might not be usable depending on the provider.

  • iPhone

Apple is known for its “walled gardens” products which make it difficult for users to perform check-ups and DIY fixes for their devices. No wonder, you won’t find any built-in diagnostic tests you can perform on an iPhone.

That being said, the iPhone settings do include detailed battery performance and history readouts. Go to Settings > Battery to find those data.

You can find a number of different options and categories that include the battery performance data on your device — but sadly nothing else besides that.

Running diagnostics scans with third-party apps

The only real option to perform diagnostics on your iPhone or iPad is to use a third-party app, with limited options included in iOS. These applications are also helpful for Android phones that don’t have built-in diagnostic tools— or if you want a more comprehensive (and less cumbersome) way of checking hardware for your device.
