The Best Hardware Test App for iPhone – Diagnose Faults in Minutes
If you are planning to buy a used iPhone from eBay or Craigslist then you will need something which can help you diagnose the hardware faults. I have found an iPhone app that can help you diagnose hardware faults of any iPhone with in minutes. I think this is the app which every iPhone user should have, because it sucks to buy a faulty phone at full price.
The best Hardware diagnostic app for iPhone
The app is called TestM and it is available in the Apple AppStore for free. Let’s take a look at some of its features. If you want to download the app and explore the features by yourself, feel free to download TestM app using the link given below.
Features of TestM:
As I told you earlier in this article, this is the best app to check hardware of an iPhone. I have listed some of the features that you can check.
Touch Screen and 3D Touch:
This app has a separate option to check if touch screen is working on all areas of the screen or not. Sometimes there are small sections of the touch digitizer that stop working because of a drop. TestM uses the same test method which is used by Apple technicians to check for faults.
All you have to do is start the touch screen test and swipe on the display and make all of the screen to change color. This app will automatically detect if the iPhone ha 3D touch or not. And if your iPhone supports it, you will also be able to test it.
Speakers and Earphone
Unlike other diagnotic apps, TestM performs a different type of test for the earphone and speaker. It speaks a random number and you will have to enter that number to pass the test. And you will only be able to enter the number if the speakers worked for you.
Vibrator and Flash
With TestM you can test the vibration motor and flash light of your iPhone. When you start the test for any of these, it turns it on and off for a random number or times and you have to count it and enter the number. This way you will be sure that it actually worked all the time.
You can also diagnose other hardware problems like Cell reception, WiFi reception, GPS, Compass etc. All in all it is a very useful utility app that I would recommend all the iPhone users to download. There is also an Android version for this app which can be downloaded for free from the Play store.
