A smartphone is a complex device, which is often highly susceptible to breakage and damage. From time to time the gadget behaves strangely, and nervous users strive to contact the service center immediately. Pleasure is not cheap, usually if it suddenly turns out that the reason was not a hardware problem, but in a software bug. There is one application on Google Play that will allow you to identify the problem with a high degree of certainty and save money on diagnostics.
The application is called TestM, and the uniqueness of this product is that having access to some hardware components of the smartphone, the application can diagnose these components and identify problems that should be noted. Did they drop the smartphone, subjected it to some other kind of hostile environment impact? Suddenly it began to catch the signal of the network badly? Do not rush to run to repair, suddenly the problem is of a programming nature and will be solved after a banal reboot.
The speaker is tested similarly: the application will say three digits, and you will need to type in what you heard. The microphone is checked by simply pronouncing the word “Hello” with its subsequent recognition by the system.
The TestM application also tests the operation of cameras, light sensor, proximity sensor, fingerprint scanner and other hardware components of the smartphone, which we regularly use, although when purchasing the device we have the opportunity to verify all of them.
Some will pay attention to the fact that the test does not include the battery test, but for this, it is rather worth to express respect to honest developers. It has repeatedly been proven that applications that calculate battery health are nothing more than fraud.
Even if it seems to you that the smartphone works perfectly, the developers recommend that it be checked regularly, and the choice is not prompt, but complete. Still, a smartphone is an essential tool in our life, and we must always be sure that it has 100% retained its serviceability. Therefore, we recommend that you install and use the TestM application from time to time, especially since it is distributed free of charge.
The program, by the way, will help and carry out a check of the device before selling, so that the buyer was sure of the product’s performance. After passing the test, the seller can share his results with the buyer: either send them by mail or save them as pictures and send them via messenger. By the way, if you know the IMEI of this device, you can independently read the test results by going to the official site of the service.
In short, this program is mandatory for installation by anyone who occasionally encounters an incorrect work of the smartphone, and this certainly happens with everyone. Although, if your faithful friend is OK, you still need to check it periodically. We do not spare time for regular physical examinations, and who said that smartphones do not need the same? Well and most importantly: the program is completely free and fully Unlocked!
