What did Riley v. California actually decide?

In 2014, the United States Supreme Court decided Riley v. California, 573 U.S. 373 (2014), and the holding was blunt. The Court said that when police arrest someone, they can seize the phone found on that person, but they cannot search through its digital contents without a warrant. The Court rejected the government’s argument that a cell phone is just another item in your pocket, like a wallet or a cigarette pack, that officers can flip through as part of a routine search incident to arrest. A modern smartphone, the Court explained, holds the sum of a person’s private life — photos, messages, browsing history, medical apps, financial records, location history — and searching it is nothing like searching a pocket. The Court’s answer to what police must do before searching a cell phone seized incident to arrest was simple: get a warrant.

Florida had already reached the same conclusion on its own. In Smallwood v. State, 113 So. 3d 724 (Fla. 2013), the Florida Supreme Court held that the search-incident-to-arrest exception does not extend to the photographs and data stored on a cell phone. The officer in that case lawfully took the phone off the arrestee, but looking through the photos on it required a warrant. The Court reasoned that once the phone is out of the arrestee’s hands, there is no more risk that he will use it as a weapon or destroy evidence with it — the two justifications that normally let police search someone incident to arrest without a warrant in the first place. Smallwood and Riley say the same thing, one from Tallahassee and one from Washington, and neither has been walked back.

Does it matter whether the phone is locked, passcode-protected, or fingerprint-locked?

The warrant requirement applies whether or not the phone is locked. Officers cannot search an unlocked phone any more than they can search a locked one — the Fourth Amendment protects the contents of the phone, not the passcode screen. What locking mechanisms raise is a separate and murkier question: can police force you to unlock the phone itself, whether by compelling your passcode or by pressing your finger to the sensor or holding the phone to your face? Florida courts have generally treated a compelled passcode as testimonial, since giving up a passcode reveals what is in your head, which can implicate your Fifth Amendment right against self-incrimination in a way that a fingerprint or face scan may not. This is a fact-specific and still-developing area, and it is exactly the kind of issue that should be raised in a motion to suppress rather than resolved on the roadside. Regardless of the unlocking mechanism, the underlying rule from Riley and Smallwood does not change: officers still need a warrant, or a valid exception, before they can look at what is on the phone.

What if I say yes when the officer asks to look at my phone?

Consent is the exception that swallows the rule in practice. If you hand over your phone and unlock it because an officer asked, you have consented to the search, and the warrant requirement no longer applies. Consent has to be free and voluntary, not the product of a claimed right to search, a threat, or a misrepresentation about what will happen if you refuse. Courts give officers considerable leeway in how they phrase the request, and a nervous “sure, go ahead” is enough to waive the protection Riley and Smallwood otherwise provide. You are not required to consent. Saying “I do not consent to a search of my phone” out loud, clearly, and once, preserves the issue without escalating the encounter. You can say this while still handing over your license and registration, still being polite, and still complying with a lawful order — declining consent to a phone search is not the same as obstruction.

Are there situations where police can search a phone without a warrant?

Yes, though the exceptions are narrow and fact-dependent. Beyond consent, the two most commonly litigated exceptions are exigent circumstances and the plain view doctrine. Exigent circumstances require the state to show a genuine emergency — a credible, imminent threat that evidence is actively being remotely wiped, or a true risk to life. Prosecutors cannot manufacture urgency after the fact to justify what was really a warrantless fishing expedition; the emergency has to be real and has to exist at the time of the search. Plain view applies only to what is visible on the screen without any manipulation of the device — an officer who sees an incoming text notification on a locked screen is in a different position than an officer who unlocks the phone and starts scrolling through the photo album. Once officers go beyond what is passively visible, they are conducting a search, and Riley and Smallwood require a warrant for that.

A validly obtained search warrant is, of course, its own exception, and the most common one in practice. Under section 933.02(3), Florida Statutes, a search warrant may issue when the property to be searched constitutes evidence relevant to proving that a felony has been committed, and Florida courts apply this provision to cell phones along with the probable cause and particularity requirements of section 933.04, Florida Statutes. A warrant for a phone still has to satisfy that particularity requirement — it cannot be a blank check to search every app, photo, and message on the device regardless of the crime under investigation. Overbroad warrants, and searches that exceed what a warrant actually authorized, are common and fertile ground for a motion to suppress.

What about my phone’s location history and data held by my carrier?

This is an area where the law has kept moving, and it moved again very recently. In 2018, the U.S. Supreme Court held in Carpenter v. United States, 585 U.S. 296 (2018), that police need a warrant to obtain historical cell-site location records from a wireless carrier, because that data reveals a detailed record of a person’s movements over time. On June 29, 2026, the Supreme Court took the next step in Chatrie v. United States, 609 U.S. ___ (2026), a case arising from a Virginia geofence warrant that asked Google to identify every phone near a bank around the time of a robbery. By a 6-3 vote, the Court held that when law enforcement obtains a person’s cell phone location data from a third-party technology company, even for a window as short as two hours, that act is a “search” under the Fourth Amendment, and the government cannot sidestep constitutional scrutiny by pointing to how little time was involved. The Court expressly rejected the government’s request for a durational “grace period” during which short-term location data could be pulled without judicial authorization.

What Chatrie did not decide is whether the specific geofence warrant used in that case was itself valid. The Court sent that question back to the Fourth Circuit Court of Appeals to determine whether the warrant, and each step of the search it authorized, satisfied the probable cause and particularity requirements the Fourth Amendment demands. So the current state of the law is this: obtaining someone’s phone location data from a carrier or tech company is now confirmed to trigger the warrant requirement, but how narrowly a geofence warrant must be drawn to survive that requirement is still being litigated. Taken together, Riley, Smallwood, Carpenter, and now Chatrie form a consistent line: your phone, and the data it generates, receive real Fourth Amendment protection, and the government has to go to a judge and show probable cause before it can dig through either one.

What should I do if police already searched my phone?

If a phone was searched without a warrant, without valid consent, and without an exception that actually applies, the remedy is a motion to suppress under Florida Rule of Criminal Procedure 3.190(h). If the motion succeeds, the evidence found on the phone, and anything derived from it under the fruit-of-the-poisonous-tree doctrine, generally cannot be used against you at trial. Getting there requires a close look at exactly what the officer did, when, and under what claimed authority: whether there was a warrant and what it actually authorized, whether consent was requested and how it was worded, whether any claimed exigency was real, and whether anything the officer says he saw was truly in plain view or required unlocking and scrolling through the device. If your phone was taken or searched in connection with an arrest or an investigation, the facts of that specific search need to be reviewed by a lawyer before you talk to anyone about what was found on it.
