Abstract: Methods, apparatus, and computer program products for protecting information stored on a computing device are described. An example of a method includes generating a first encryption key based on a previously stored factory reset value, encrypting, by a processor, at least a portion of information associated with an application using the first encryption key, storing the encrypted at least the portion of the information associated with the application in a memory of the computing device, obtaining, by the processor, a request for a factory reset of the computing device, in response to the request for the factory reset of the computing device, replacing, by the processor, the previously stored factory reset value with a new factory reset value, and disabling decryption of the stored encrypted at least the portion of the information associated with the application by generating a second encryption key based on the new factory reset value.

Abstract: Signals of different cells in a cellular wireless communications system are observed during associated intervals to predict a signal behavior in future. A target cell is selected by observing over time signal characteristics of potential target cells. Thereafter a target cell is selected by using the observed characteristics to predict which potential target cell will in future satisfy certain criteria.

Abstract: Cell reselection comprises monitoring a first indicator indicative of a signaling level of the serving cell, and monitoring second indicators, each indicative of a signaling level of one of plural potential target cells. A timer associated with a potential target cell is initiated when the respective second indicator indicates that the signaling level of the potential target cell is better than the signaling level of the serving cell. Each timer has an associated expiry, and, if at least one timer has been initiated by the expiry of another initiated timer, then, after delaying for an additional period after at least the first timer has expired, a target cell is selected from the potential target cells. The target cell is selected that has a second indicator which indicates that the signaling level of the respective target cell is better than the signaling level of the serving cell.
