As explained here by Carlton Fields Jorden Burt’s Chas Short, the Eleventh Circuit recently issued its decision in United States v. Davis, No. 12–12928, --- F.3d ----, 2014 WL 2599917 (11th Cir. June 11, 2014), expanding on the Fourth Amendment protections provided to users of mobile phones regarding the type of information that can be gathered the location of such devices.  Davis’ approach to this issue is consistent with the United States Supreme Court’s June 25 decision in Riley v. California, which held that law-enforcement personnel generally cannot search the contents of a mobile phone without a warrant (even if the device is seized incident to the arrest of its user).
