Fake Device Test

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.

The included Full SD Memory Test will identify defective and fake External SD cards. This test is more thorough than other SD memory testing apps because it verifies that every bit in the SD card's free memory space can be both set and cleared. We do this with two passes of test data which can not be compressed. These two passes will set, clear, and verify that every bit is fully functional. Apps performing only a single pass test are only testing half the memory bit states (either set or cleared), and therefore are only 50% accurate and reliable. Running a single pass test app multiple times will still not verify all the memory bit states, because the test data must be specially formulated to set and clear each bit in the memory. Our test does this and is 100% accurate and reliable.

We have tested supporting OTG flash drives with the "Full Memory Test", and found that it's not practical to do. The issues we found are:

1. OTG flash drives are slow on most Android devices (<10-30MB/sec), so they would require long testing times.

2. OTG has high power demands on the device battery.

3. You can't charge the device while testing OTG

These issues combined, limit the OTG flash drive testing size to about 16GB or less, due to depleting the device battery power on most devices. Since most flash drives that are commonly used today are much larger than this, it makes this testing method impractical. If OTG flash testing becomes more practical in the future, we will reconsider adding this functionality.

检测伪造的设备，这些设备的固件经过修改，掩盖了设备的实际/实际硬件规格。其他设备测试应用程序通常将无法报告伪造设备的真实规格，因为它们仅报告操作系统告诉他们的内容，即伪造规格。这可能是Play商店中唯一能够报告真实设备规格的应用程序，因为我们不依赖于操作系统所报告的内容，而是通过运行测试来找到真实的规格。

在Ebay上出售的许多平板电脑（尤其是来自中国的平板电脑）都安装了经过修改的操作系统，其中报告了虚假/虚假的规格。这样做是为了使购买它们的人不会知道他们已被骗。创建此应用程序的目的是通过暴露这些设备并显示其真实规格来保护人们免受欺诈。

随附的完整SD内存测试将识别有缺陷和伪造的外部SD卡。此测试比其他SD内存测试应用程序更彻底，因为它可以验证SD卡的可用内存空间中的每一位都可以设置和清除。我们使用无法压缩的两遍测试数据来执行此操作。这两个过程将设置，清除并验证每个位是否都正常工作。仅执行一次通过测试的应用程序仅测试一半的存储位状态（设置或清除），因此准确度和可靠性仅为50％。多次运行单次通过测试应用程序仍不会验证所有内存位状态，因为必须专门制定测试数据来设置和清除内存中的每个位。我们的测试可以做到这一点，并且100％准确可靠。

我们已经通过“全内存测试”测试了支持OTG闪存驱动器，但发现这样做不切实际。我们发现的问题是：

1. OTG闪存驱动器在大多数Android设备上速度较慢（<10-30MB /秒），因此需要较长的测试时间。

2. OTG对设备电池的功率要求很高。

3.测试OTG时无法为设备充电

这些问题加在一起，由于大多数设备上的设备电池电量耗尽，因此OTG闪存驱动器测试大小限制为大约16GB或更小。由于当今大多数常用的闪存驱动器远不止于此，因此这种测试方法不切实际。如果将来OTG闪存测试变得更加实用，我们将重新考虑添加此功能。
