DtxCaliente

It seems that DtxCaliente was introduced in factory firmwares such as Sundance 10A23941s that are based on internal versions of iOS 6.0 and up. From what we can see, it looks to be an LCD testing application that monitors device temperature before and after running tests on the LCD. These tests consist of black and white patterns flashing on the screen every few seconds. These patterns can also be found in LcdUTest. To begin a test, simply remain idle in DtxCaliente or press volume up in DtxCaliente.
