There are many third-party applications available online to check diagnostics on any phone, but using those no so trustworthy apps might make our iPhone vulnerable to viruses. So make sure you are downloading the apps from the App store only. The apps mentioned below are some of the third-party applications available on the app store to run diagnostics on your iPhone as well as your Android too. All these apps work the same except for the interface and the different kinds of tests they run to check the phone. The apps are Phone doctor plus, TestM, Phone Diagnostics, etc.

We will see the step-by-step process to download and test the iPhone using TestM.

Go to the App Store and download the TestM app, the one with the blue icon and a white tick over it.

  • Open the app, allow the requirements, and agree to the terms and conditions.
  • The app has two kinds of tests, a full test, and a quick test. A full test conducts all the tests like front Microphone, rear Microphone, flash, speaker, touch screen, and many more. They also include memory, Wi-Fi, network, Bluetooth, GPS, camera, CPU, charging, etc.
  • Whereas a quick test lets you choose a particular test you want to conduct and run it.

Let us see how we can do a full test on iPhone using the TestM application. An estimated time is calculated and displayed on the screen.

1. The Touch Screen Test: Once it is activated, the app asks us to Scratch to clear the screen to check if all the pixels are working properly or not.

2. The Headphone Test: We have to plug the wired headphones into the phone and listen to the 3 numbers the app says on the headphones. We need to enter these numbers when prompted on the screen. The same goes for the Earpiece test and the Speaker test too.

3. The Microphone test: To test the microphone we need to say “Hello” on the front, back, and bottom microphones. Give access to your Microphone and say hello for each microphone test.

The Accelerometer test asks us to shake the phone for 3 seconds and the Compass test to put the phone down and slide the screen down for 3 seconds.

4. The Bluetooth Test: To do this test, make sure your Bluetooth is switched on and your phone is placed near a discoverable trusted Bluetooth device to begin. Switch off the Wi-Fi too.

5. The Wi-Fi test: Just connect to a Wi-Fi source, and you are good to go.

6. The GPS Test: Turn on location services and turn off Wi-Fi. The GPS test the indoors and the outdoors too, so you have to go outside to run this test.

The Proximity Test checks the availability of sensors at the front camera and the Charging Test monitors whether the charging port is working properly or not.

9. The Face ID test: We will have to look at the front camera for the verification of the Face ID. This feature is only available for iPhone 10 and above.

These tests also include camera tests, wireless charging tests, etc.

After running all these tests, if you find an error or are unable to complete any of those tests, you can either visit an Apple store to get it rectified or a mobile store nearby.
