iOS app software company RealityCap released a fix to Apple Inc's iPhone 5S sensors. The fix was meant to address the inaccurate readings from the smartphone's sensor. As early as October, majority of the iPhone 5S owners had reported that sensor information on motion, level and acceleration were off 5-6 degrees at most. A test conducted by tech and gadgets news site Gizmodo had affirmed such reports.

On a blog entry today, RealityCap chief executive Eagle Jones wrote, "Since the bias is more or less constant, a simple one-time calibration process can correct for it. There are several ways to approach this, but we find it most straightforward to ask the user to place their device on a flat, level surface. We then capture accelerometer data over a period of time (to smooth out any vibration or noise in the measurements)."

Apple has yet to provide a comment or address user reports about the faulty sensor on the latest iPhone unit.

This was not the only issue owners of the iPhone 5S had encountered. Earlier, some users claimed, and some even showed video proof, that the iPhone 5S would show a blue screen of death. The blue screen of death is the signature error screen that would only happen in devices running on Windows operating system.

Combined sales of iPhone 5S and 5C sold a record 9 million units in the first three days of its debut. Although Apple had yet to provide a breakdown of the number of units sold per iPhone, recent rumors of a reduction of iPhone 5C assembly orders had confirmed industry data that Apple sold more iPhone 5S units than iPhone 5C units.
