Planning to buy a used smartphone? The device you are just about to buy may have some defects, did you ever think of that? How to protect yourself against such odds? How to choose wisely while buying a used smartphone? Well, here are some tips and tricks to ensure that you buy the best of the choices available.

One of the stages of verifying your smartphone is called Stress Testing. This includes stressing your phone’s CPU to the maximum possible. While not for everyone – particularly those uncomfortable with breaking their device -stress testing provides a great way of discovering potential future issues with the hardware.

Next comes the Diagnostic Testing technique. The ideology behind this test is to test the hardware components which are accessible externally to the user. These include micro USB slot, SIM card slot, earphone jack and the micro SD card slot. The phone’s sensors, such as the gyroscope or accelerometer, can’t be examined or tested through physical inspection. Fortunately, you can install software capable of scanning your device’s sensors. Two of the best apps for checking your phone out are Android Sensor Box and Elixir 2.

Android Sensor Box After you install and run the app, the start screen essentially shows each of the sensors of your phone. Disabled components will show a red circle with a line through it over the icon. Broken components, when tested, will show erroneous sensor readings. For example, if you use the “Orientation Sensor” and the bubbles don’t move at all, it means the sensor is either broken or miscalibrated.


Elixir 2 It only provides a readout of the function sensors – but even so, it’s an amazing program. Its functions range from providing sensor analysis to a detailed breakdown of internal hardware components. It’s actually a one-stop shop for vetting an Android handset.
