The average repair of a broken mobile phone costs CZK 4,300.  How do we protect it most often?

If something happens to your phone during normal use, you will typically have to visit the store where you bought the phone or send it to a service center. The biggest problem, however, is that the error you describe may not be reflected in the service, so the phone is returned to you, and of course uncorrected.

If something unusual is happening to your phone, the first step should be so-called self-diagnostics. The phone finds out for itself whether its components work properly, and if it finds an error, just a screenshot and you have proof of which of the components does not work as it should. Samsung has an edge in this area, as it offers self-diagnostics for all its phones, within the Samsung Members application. Other Androids don’t really “sharpen”, but they have to use universal apps from Google Play.

For Samsung, bet on Samsung Members

If you have a Galaxy phone, then the blue Samsung Members icon is waiting for you in the main menu. If you don’t happen to have it on your Galaxy phone, you can download it here. In the new version of the application, you get to check the hardware, either at the touch of a button Diagnostika or via the menu Get help – Diagnostics. The content of the tested components differs from model to model (eg you will not test the stylus on phones that do not support it), in the case of Galaxy Z Fold3 you have 24 tests available.

For Samsung, you can count on pre-installed diagnostics in Samsung Members

The tests cover battery, display, network, vibration, sensors, buttons, charging, sensors, speakers, connectivity, cameras, lighting, accessories, biometrics and software. You can perform the tests manually in the order you need, or you can have a complete test performed all at once.

How to Android self-diagnostics:

Some tests cannot be performed immediately, for example you need to buy a stylus or open the phone, but checking the hardware (and software) will give you a general idea of ​​whether something is wrong with the phone. If you do not finish checking some sections, the test icon will be displayed in orange until you meet the newly set test condition (eg restart the phone, connect headphones). The individual sections of self-diagnostics also offer useful tips on how to actively prevent some problems.

Other Androids have a “doctor”

The scope of the tests is comparable to, and perhaps surpassed by, Samsung’s applications Phone Doctor Plus 2021which you can download for free from Google Play. The application offers more than forty types of hardware and software diagnostics. First you need to enable all the permissions (yes, there are a lot of them) and then there will be a gradual automatic testing of everything that can be tested on your particular phone.

For other Androids, you can use the universal Phone Doctor Plus 2021 app

You need some cooperation, for example, you have to turn the phone, erase all the squares by touching your finger on the screen, approach the NFC device, connect the USB connector, turn off Wi-Fi and much more. The tests go so fast that you often don’t get a pipe just because you didn’t have time to read the instructions. You can return to the basic tests separately, but you will need free registration to access the failed “professional” tests.

There are really a lot of tests, and you can detect a number of possible shortcomings on your phone. The application also includes modules for purchasing or ordering original parts, but we are not very interested in them. For some, memory cleaner or battery “health” testing may be important. And if granting a range of permissions is wrong for you, you can uninstall the application right after the diagnostics are complete. However, at least take screenshots of any failed tests and attach them to the phones you send for repair.
