The apparatus can include a screen, and located under the screen are a plurality of fingerprint scanners, the plurality of fingerprint scanners corresponding to respective regions of the screen. An interface requests a location of the screen that an application uses for a fingerprint scan.

Abstract: Auto-recovery from RF signal acquisition failure may be provided in a portable computing device. A field-calculated frequency-temperature (“FT”) curve is used to apply temperature compensation to a crystal oscillator associated with RF transceiver circuity of the device. In response to acquisition failure, it may be determined whether a deviation between the field-calculated FT curve and a factory-set FT curve exceeds threshold criteria. In response to acquisition success, the field-calculated FT curve may be refined based on frequency error information. However, in response to acquisition failure and a determination that the deviation exceeds the threshold criteria, information defining the field-calculated FT curve may be replaced with information defining the factory-set FT curve.

Abstract: In currently available mobile devices (e.g., a user equipment (UE)), no authentication occurs at the mobile device to answer an incoming call at the mobile device. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus for secure call answering are provided. The apparatus is a first UE. The apparatus receives an incoming call originated from a second UE. The apparatus determines whether the incoming call originated from the second UE is a secure incoming call.
