TestM is a useful tool that allows us to perform detailed analyzes to our smartphones to check the status of the hardware. It is an app whose main purpose is to check the status of a phone that you just acquired or make a diagnosis of one that you plan to put on sale. All thanks to the complete report that TestM provides once the relevant tests have been carried out.
This free app allows us to perform tests that evaluate the different elements of the phones to analyze: the operation of the screen, the sound, the sensor of the movement, the connectivity, the sensors or the different cameras with which it counts. Each test will focus on performing small exercises that check each of these sections effectively. If for example we are checking the touch screen, we will have to eliminate some squares in a set time, or if we are analyzing the state of the gyroscope we will have to move the phone in a certain way.
TestM is an excellent application to make a detailed diagnosis of the status of a mobile phone. Very useful to know if we have a stolen phone in hand or if we can use it in our country. In addition, it has a map that indicates nearby repair shops in case we need to fix any of the problems you have.
