Is This the Source of Apple’s iPhone 5S Motion Sensor Problems?
Earlier this month, tests conducted by Gizmodo demonstrated that many of the motion sensors in Apple’s (NASDAQ:AAPL) iPhone 5S were improperly calibrated. Although the source of the problem was unknown at the time, Gizmodo noted that a software issue would likely be easier to fix than a problem that originated in the device’s hardware.
However, it now appears that the iPhone 5S motion sensor issues are due to a new accelerometer part that is not found in previous Apple devices. According to RealityCap CEO Eagle Jones via Gizmodo, the culprit is the Bosch Sensortech BMA220 accelerometer.
As noted by the Chipworks’ researchers who recently completed a teardown of the iPhone 5S, this is the first time that Apple has ever used this Bosch part in its devices. “Previously this has been a socket dominated exclusively by STMicroelectronics (NYSE:STM),” noted Chipworks.
