Smartphones should not have a ‘kill switch’ if they’re stolen

Cathy L. Lanier, the chief of police in Columbia believes “carriers are not innocent” when it comes to phone theft. They aren’t inclined to make phones less attractive to thieves, because, as she puts it, they’re “making a profit off this.” She’s referring to the fact the victim will usually have to buy a new phone, or must cough up cash to buy their way out of a contract.

Lanier’s comments are part of a New York Times piece on this very issue, suggesting the mobile industry is, “Looking the other way,” as phone thefts continue to rise. To highlight the problem, it’s said thefts involving a phone now account for half of all robberies in San Francisco, while last year the figure was 36 percent. While we may giggle at the stupidity of some thieves, the New York Times paints a far more serious picture, with one police lieutenant calling the gangs behind the major operations, “Well organized, very tech savvy, well trained and well funded.”

The industry’s primary weapon in the fight is the national, unified database which stores the IMEI numbers (every phone has a unique IMEI) attached to stolen phones, which, in theory, prevents them from being re-used. Databases like this are maintained all over the world, and in time, the U.S. database will be merged with international versions to help stop stolen phones being sent out of the country and re-connected elsewhere.

However, according to the New York Times, IMEI numbers are being altered so they no longer show-up on carrier’s blacklists, enabling them to be sold on and connected without a problem. The District Attorney for San Francisco, George Gascon, holds manufacturers responsible for not doing enough to secure mobile phones, saying, “Unlike other types of crimes, this is a crime that could be easily fixed with a technological solution.” The carriers, represented in the article by T-Mobile, aren’t helping themselves either. A T-Mobile representative could only say, “we do care very deeply about this,” but was quiet about any potential solutions.

So is this, as the district attorney says, an easily fixable problem? There are several safeguards we as smartphone users can already take to make the loss of a phone less problematic, with several companies offering tracking solutions, and Apple’s Find My iPhone device tracking system coming as standard. But the DA wants manufacturers to include a, “kill switch,” which sounds like a cross between an EMP device and the system used to convey messages to Ethan Hunt.

This isn’t the first time the San Francisco district attorney has brought up the idea of a kill switch, but he has been frustrated by the industry’s lack of interest in developing one, which he claimed is due to profits. A VP of mobile security firm Mobile Iron told Information Week earlier this year that kill switches were, “Technically feasible,” but offered few advantages outside of the business world. For regular users, he saw the available remote wipe features pre-installed on phones, or systems like Norton Mobile Security, as being sufficient.

Kill switches are already used by manufacturers, and although Apple has never used the one installed on the iPhone, Google has flexed its muscles twice in the past, each time to remove malicious applications after they had been installed on active Android phones. The trouble with the idea of a central kill switch is not that it could inevitably be bypassed (Apple’s has been deactivated in the past through jailbreaking the phone), but who would be in control. Giving carriers the legal right to zap a phone from existence may sound good after it has been stolen, but less so if excuses could be found for using it against late payers, modified phones, or those installing unapproved software.

Police forces around the world have successfully recovered stolen phones using Find My iPhone and similar systems – the Metropolitan Police in the UK even recommends turning it on, and has a guide on how to do so on its website – but don’t always have the resources to follow up each case, which can be frustrating for victims of crime.

There’s no doubt Cathy Lanier and District Attorney Gascon are correct in one sense, that the problem of smartphone crime needs addressing, but we’re not convinced kill switches are the answer. However, if a truly international database of stolen IMEI numbers could be implemented quickly, and all networks around the world were compelled to update it, this along with systems such as fingerprint scanners fitted to phones and the existing remote wipe features, could at the very least stem the tide.

Google Chrome is getting an AI-powered scam sniffer for Android phones
Scam warning from Chrome on Android.

Google’s Chrome browser has offered a rich suite of privacy and safety features for a while now. Take, for example, Enhanced Safe Browsing, which was introduced back in 2020. It protects users against unsafe websites and files by using real-time threat detection. 

Three years later, Google switched it from an opt-in mode to a default safety protocol to guard users against phishing attacks, bad extensions, and malicious downloads. Now, the company is deploying its Gemini Nano AI to safeguard smartphone users against potential online scams, especially those hiding as a tech security warning on webpages.

Google Messages finally gets proper unsend functionality with ‘Delete for everyone’
The Google Messages app on the Galaxy S25 Ultra.

Over the years, Google Messages has picked up features that elevate its status to a deserving Apple Messages substitute. The latest addition, allowing you to fully unsend messages, is now reaching a breadth of Android users, saving them the pain of awkwardness of wrongly sent texts.

After previewing the "Delete for everyone" feature in its Messages app, Google is releasing it to people beyond the beta testing tribe. As expected, the functionality allows senders of the message to delete it for all parties in a peer-to-peer or a group chat and replaces older functionality where deleted messages would still appear for others.

Every phone should copy this Galaxy S25 Ultra feature

Samsung introduced a new display feature with the Galaxy S24 Ultra and has only improved it on its latest flagship. The Galaxy S25 Ultra’s screen lies under the protection of Corning Gorilla Armor 2, which is a step above the typical Corning Gorilla Glass found on most smartphones.

The Gorilla Armor series debuted with last year’s Galaxy S24 Ultra and brought anti-reflective properties that claimed to lower surface reflections by “up to 75 percent.” It was a genuine quality-of-life upgrade as it improved screen visibility in harsh lighting and enhanced durability. It delivered over four times better scratch resistance and up to three times better drop resistance compared to “competitive aluminosilicate cover classes.”
