There’s rather a lot much less to decide on between Android and iPhone than was the case. And whereas Google appears to do extra following than main, a shock new replace simply revealed for Android has overwhelmed Apple at its personal sport…
Android simply dialed safety as much as 11

Up to date 3/31; initially revealed 3/29.
Android and iPhone are coming ever nearer collectively, and in latest weeks we’ve seen previews of iPhone options that Google is lifting for Android, together with encrypted WhatsApp calls in cellphone dialer lists and satellite tv for pc SOS messaging.
However we’ve additionally seen Apple transfer iPhone in Android’s course, particularly with the surprising information that iPhone could use Gemini and Baidu generative AI as an alternative of Apple’s personal for the heralded chatbot performance anticipated with iOS 18.
However nothing has ready us for what Google additionally simply revealed in its newest Android 15 developer launch. In a shock transfer that’s extra iPhone than iPhone, it appears like Android could also be taking privateness to the subsequent stage, with new units in a position to cover their areas even from their networks.
Much more markedly, Google has additionally previewed a characteristic to guard units from IMSI grabbers and intercept platforms. These are the applied sciences utilized by regulation enforcement and typically criminals to seize cellphone IDs and trick these telephones into connecting to a copycat community, permitting calls and messages to be intercepted.
Android has performed on this area earlier than—however not like this. Way back to Android 12 and extra notably in Android 14, units have been in a position to lower off low-level mobile capabilities that might drop a cellphone from encrypted to insecure comms. This makes it a lot more durable to run an intercept, however the options have been buried and arduous to search out. What we’re about to see is that this stage of privateness hit the mainstream.
The catch is that each these updates require a brand new interface between the radio modem and the cellphone’s OS, as a result of the IMSI seize and intercept are on the radio aspect not the OS aspect. Modems will want to have the ability to run the software program interface, which suggests new modems. You’ll in all probability have to improve your {hardware} not simply replace to Android 15. It’s seemingly Google telephones will get this primary, however others will observe.
Mishaal Rahman found the replace, explaining that grabbers and intercepts “are in style amongst regulation enforcement as a result of they permit for the covert assortment of knowledge from prison suspects, however they’ve additionally been utilized by malicious state actors to spy on journalists… they put particular person privateness in danger as a result of there are few safeguards in opposition to them. That’s why Google has been engaged on updating Android to forestall units from sending textual content or voice knowledge over older or unencrypted protocols.”
A tool with a modem that helps the brand new know-how layer will current a consumer warning when a tool ID is captured by a community or linked to an insecure community with out the anticipated stage of encryption. This implies a possible intercept, the place the machine is knocked off its typical service onto a high-powered and fewer safe native radio community mimicking the mobile service. All visitors is then routed by the faux community and both captured as its backhauled to the actual community or lower off.
The community location info is completely different. Most location knowledge we talk about in the case of telephones is device-centric. Your cellphone makes use of GPS and different applied sciences to find itself. That may be shared with apps or pals, and we’ve seen a number of privateness updates to limit apps accessing this functionality, particularly in secret.
The cellphone community may also ping your machine and request its exact location, and it’s this characteristic that may be lower off except there’s an emergency, for instance you’re making a 911 name or sending an emergency textual content message.
As Rahman explains, whereas Android has already adopted iPhone in offering extra rigorous restrictions on app entry to location knowledge, “the OS can do little to forestall your service (mobile community) from getting your location. In Android 15, although, the OS would possibly get a solution to stop your location knowledge from being despatched to your service.”
This received’t cease carriers utilizing old skool cell tower triangulation. Any cellphone connecting to as community might be situated, because it pings a number of towers concurrently and the placement of these towers and energy of these connections permits a broad location to be derived. This isn’t pinpoint in the way in which we’re used to with GPS, however it does permit telephones (and their customers) to be positioned in sure areas at sure instances.
That is thrilling stuff for Android customers. We at the moment are venturing into a brand new stage of privateness and placement masking, with a number of the continued machine vulnerabilities on the radio aspect being addressed. And whereas this will likely be welcomed by privateness advocates, you possibly can wager that regulation enforcement businesses will likely be taking a look at what this implies and the way such defenses might be labored round as crucial. I’d count on the emergency override could also be triggered by regulation enforcement below sure circumstances.
Over to the modem OEMs now to see how shortly this know-how makes its approach into the radios, so the brand new Android software program can step up its interface and controls.
Apple offers a lot wider location controls on iPhone than Android, together with community search and enhanced emergency name info. However it has not but raised the profile of these restrictions as we’re seeing Android do right here. I’d count on a extra detailed comparability between the 2 to return out, with the element behind what a radio community can and can’t do on an iPhone and the way the OS and modem interface.
And that’s what most attention-grabbing right here—Google taking a lead in messaging and consumer transparency on the privateness entrance, floor that has all the time been Apple’s up to now.
As ever with this stage of cellphone safety and privateness, it’s good to have even when it received’t be a game-changer for the overwhelming majority of customers. However for journalists, politicians, celebrities, dissidents and protesters, this can be a main advance within the enchancment of private privateness and knowledge safety and is as welcome as it’s stunning.
3/31 replace: Unsurprisingly, the information that Android 15 is bringing these new privateness advances has sparked attention-grabbing on-line debate. “It is nice that Google is taking the {hardware}/software program safety hyperlink extra critically,” one Reddit consumer posted. “This nonetheless doesn’t cease SIM swappers or anybody else from instantly concentrating on you. It simply moved the bar for dragnet radio surveillance a lot greater. Which is all the time good.”
The query on iOS comparisons has additionally come up. We all know that iOS 17 launched the identical sort of 2G blocking that Android launched as a extra primary precursor to those new applied sciences. However solely in Lockdown Mode. EFF welcomed this as “an enormous step in direction of defending iOS customers from faux base station assaults, which have been used as a vector to put in spyware and adware reminiscent of Pegasus.” However, because the title implies, Lockdown Mode is for specialist customers at greater danger, and isn’t for everybody.
Apple says itself that “Lockdown Mode is an elective, excessive safety that’s designed for the only a few people who, due to who they’re or what they do, could also be personally focused by a number of the most subtle digital threats. Most individuals won’t ever be focused by assaults of this nature. When Lockdown Mode is enabled, your machine received’t operate prefer it often would. To cut back the assault floor that would probably be exploited by extremely focused mercenary spyware and adware, sure apps, web sites and options will likely be strictly restricted for safety, and a few experiences is probably not out there in any respect.”
That’s the actual information right here—Google making this stage of safety extra mainstream, providing warnings when a tool detects uncommon community exercise.
So-called Stingray units depend on knocking telephones all the way down to 2G with its inferior safety, however that’s not sufficient anymore. Android’s authentic defenses and the iOS 17 protection defend customers in opposition to this legacy approach, however newer units—Hailstorm for instance—can function on 4G networks in a approach that wasn’t doable earlier than.
5G provides enhanced safety in the way in which IMSI knowledge is dealt with and transmitted, and so if you’re in an space with good 5G connectivity then you’re higher protected. Albeit that received’t cease a powerful native radio making an attempt to knock you all the way down to 4G. And it received’t defend you in areas with out 4G or when your 5G connection is simply LTE+.
Whereas praising Android’s early efforts and Apple’s Lockdown Mode, EFF was very vital of Samsung. “Up to now Samsung has not taken any steps to incorporate the 2G toggle from vanilla Android, nor has it indicated that it plans to any time quickly. {Hardware} distributors usually closely modify Android earlier than distributing it on their telephones, so although the setting is out there within the Android Open Supply Challenge, Samsung has to this point chosen to not make it out there on their telephones… These failures to behave counsel that Samsung considers its customers’ safety and privateness to be an afterthought. These involved with the safety and privateness of their cell units ought to strongly think about using different {hardware}.”
As such and given the necessity for modem and OS to work collectively, will probably be attention-grabbing to see if Samsung will get onboard with these Android 15 modifications shortly, not like what has occurred earlier than.
Methods aren’t made public for apparent causes, however taking a look at rogue community exercise and warning customers when one thing is detected is necessary. It’s a serious advance on simply disabling 2G. When a cellphone is attacked, there’s a course of at play. And detecting components of that uncommon exercise is the perfect protection. Clearly, a delicate consumer seeing such a warning will instantly shut down the cellphone.
As for the community location detection, debate has ensued as to the accuracy of cell tower triangulation. “So long as you are connecting to their towers they know an approximate location. No matter machine settings,” stated one Reddit consumer. “Having labored in a division that supplied mobile location data to authorities, I imagine it may be narrowed all the way down to roughly 15-25 meters,” posted one other.
The rule right here could be very easy—it relies upon the place you’re. In a busy metropolis location with numerous cell towers throughout you, location accuracy is fairly good. However head out right into a rural setting, with fewer towers and additional distances between them, and it’ll range wildly. One thing to keep in mind…
