This app detects fake devices that have modified firmware which conceals the real/actual hardware specifications of the device. Other device testing apps will usually fail to report the true specifications on faked devices because they only report what the operating system tells them, which is fake specifications. This may be the only app on the play store that will report true device specifications because we do not rely on what the operating system is reporting, we find the true specs by running tests.
Many tablets being sold on Ebay, and especially coming from China have a modified operating system installed on them that reports fake/inflated specifications. This is being done so that the people who bought them won't know they have been scammed. This application was created to help protect people from this fraud by exposing these devices and showing their true specifications.

(Important Update) - We received a report that some of the newer fake devices may be blocking the install of this app in their firmware to avoid detection. This app will install on any device from this play store listing. If you are unable to install this test, then the device itself is blocking the install, which is proof the device is fake and is purposely blocking the install to avoid detection. Such devices should be returned immediately for a refund, because you are being scammed. Everyone should insist on being able to install this test to check their device's authenticity, and demand a full refund for any device that is blocking your rights to do so.
