In the age of the flip phone, diagnostics focused on battery tests, functional buttons, and maybe the odd cellular signal test.Today, in the age of the smartphone where phone diagnostics is rapidly developing, you’re looking at bluetooth testing, battery testing, WiFi testing, and more before your phone earns any sort of pre-owned certification.It makes buying and selling phones on the used market safer, but also increasingly difficult. If you’re not running top-notch diagnostics, no one is going to trust you as a seller. So what do phone diagnostic apps actually do and how can they benefit your resale value?
Every phone comes with a different method of testing. These vary by phone manufacture, but also by operating system. Thinking about the tools as Android, Microsoft, and iOS centric works best for broad purposes.While each company’s tool differs, they all test largely the same things. That is, any and all smartphone functions.They also send back data to their parent company for further review. This helps the operating system manufactures patch persistent problems.Let’s go over some of the larger tests these apps perform.
Bluetooth technology connects your phone to many different devices. Other phones, headphones, printers, etc. Diagnostics apps will run a brief test to ensure your smartphone can both send and receive requests to “pair” with another device.
Ever wonder how your phone screen rotates from vertical to horizontal? That’s your accelerometer at work . Testing your phone’s accelerometer is important to determine the usability of your phone. Imagine if your phone erratically shifted screen orientation. Not good.
Modern cellphone screens contain an incredible amount of pixels. Apple’s iPhone 7 screen has 330 ppi, while Google’s Pixel has 440 ppi. If you’re wondering just how many pixels that is, from a normal viewing distance the human eye can’t distinguish anything more than 300 ppi.Your phone diagnostics app will flash your screen through different colors to check for dead pixels. At high pixel densities screen defects are very apparent.
Your phone’s proximity sensor “senses” how near or far your mobile is to your face. It’s how the phone knows to turn the screen off when you’re talking on the phone. Diagnostics testing will send signals to the sensor to test its sensitivity. Similar to the accelerometer testing; can you imagine if your phone screen turned on and off by itself?Any phone diagnostics app allows users the ability to put their phones through its paces. The tests check advanced functions (aforementioned) and basic functions alike. If you’re putting your phone up for sale, it’s important to run diagnostics to gauge how much money your handset is worth, if any at all.Those really interested in even deeper diagnostics testing can turn to third party solutions that run independent across device manufactures.These solutions are the best option for most businesses, as the more impartial and thorough your testing, the better your phones will fare on the resale market.
