A developer believes to have found the reason for the reported buyers of the Apple iPhone 5S problems with the motion and position sensor. RealityCap that develops 3D APIs , has for the first time used in Apple's smartphone chip from Bosch Sensortech suspected .
In a blog post , CEO of Eagle RealityCap Jones refers to an analysis of the components of iPhone 5S Chipworks . According to her, now comes a Bosch BMA220 Sensortech as a motion sensor used. He replaced the 5S and probably also in the 5C STMicroelectronics LIS331DLH , the iFixit had found in the iPhone fifth
Jones has compared and found that a five times higher systematic error is given for the Bosch module data sheets of the two components . Factors such as mechanical stress or temperature fluctuations may affect the outcome more than the motion sensor STMicro . This fits exactly to the observations of testers .
So the blog Gizmodo had found the test with EA Real Racing 3, the sensor of the iPhone 5S registered immediately after the start of a race , a movement to the left and the vehicle controls in this direction , although the phone without any external influence on a flat surface is . According to Gizmodo, the most affected is the native compass. When the direction indicator it is compared to the iPhone 5 at the average deviations from 8 to 10 degrees , although both devices running on iOS 7th
RealityCap CEO Jones goes on to say that the old and the new part costs about a dollar. Apple has thus not changed to Bosch to save money. Rather, the component used now need less power than its predecessor.
If the assumption is correct, the error could probably not be corrected by an update of iOS . But Jones assumes that developers could integrate a calibration process in their apps , such as by bringing him also the compass app on startup. Thus, the current bias it possible to determine to correct later results automatically .
