- Google introduces a mandatory 24-hour waiting period for installing apps from unverified developers.
- The new "Advanced Flow" adds extra steps such as developer mode, restart, and re-authentication.
- Verified apps and official stores will barely notice any changes; the impact falls on APKs and alternative repositories.
- Advanced users retain shortcuts such as ADB and limited distribution accounts to circumvent some of the restrictions.
For years, Android has been synonymous with freedom to install applications from almost anywhereThis clearly differentiated it from iOS. That possibility still exists, but Google has announced a profound change in how it's done, introducing a key element: 24-hour wait before the installation can be completed of certain apps.
The company does not eliminate the side loadingbut it does surround it with more friction and more steps when the app comes from an unverified developerThe stated goal is to make scams that rely on social engineering more difficult, although for many advanced users the new system will mean a much more cumbersome process for installing a simple APK.
What exactly changes: from immediate APK to 24-hour wall
Until now, for most users it was enough to download an APK file and run it To have a third-party app running on your mobile phone or Android TV, this feature disappears with the changes Google is rolling out if the developer hasn't verified their identity within the new Android program.
The central piece of the system is a 24-hour protective waiting periodIn practice, this means that, although you can still install apps from outside Google Play or other official stores, You will no longer be able to do it impulsively or guided in real time by another personYou'll have to start the process, restart your device, wait a whole day, and only then decide whether to continue.
Google frames this change in a worrying context: it estimates that More than half of adults have been victims of some kind of attempted scam in the last yearOften, these scams are perpetrated through fake apps that impersonate banks, government agencies, or messaging services. Many of these frauds rely on phone calls or remote access where the attacker dictates each step to the victim.
The company insists that The installation of third-party apps does not disappearThe difference is that, if the creator is not verified, the system is no longer a matter of a couple of taps but becomes a long process, designed to force the user to stop, think about it, and have time to check if what they are installing makes sense.
The new "Advanced Flow": six steps to install an unverified app
The change isn't just about adding an extra notification; it sets up a whole workflow that Google has dubbed "Advanced Flow"This process will apply when you want to install an app developed by someone who is not yet part of the Android verification system, whether from a website, an alternative repository like F-Droid, or a third-party store (you can search for apps for Android and iOS).
In order to install these types of applications, the user will have to complete a sequence of six linked steps that break the idea of quick installation:
- Manually enable developer mode In the system settings, tap the build number several times. Simply checking the "unknown sources" box will no longer suffice; you'll need to access a more advanced and specific section.
- Responding to a warning about possible coercionAndroid will explicitly ask if someone is guiding you by phone or remotely to disable system security protections.
- Restarting the device is mandatoryThis step cuts off any active calls or remote access sessions, which is key if a scammer was monitoring or tracking what you're doing.
- Accept a 24-hour block before you can continue. You will not be able to complete the app installation during that day, even if you have already downloaded the file.
- Reauthenticate with PIN, fingerprint, or facial recognition once the waiting period has passed, to confirm that you are still the one making the decision.
- Finally install the app, with visible warnings that the developer is not verified and with two options: allow these types of installations only for seven days or enable them indefinitely.
According to Google, this flow was designed after testing different scenarios with advanced users. finding a balance between safety and discomfortThe chosen point —that full day of waiting— seeks to put a stop to scams that rely on urgency: if the attacker needs the victim to install something "right now", the system simply won't allow it.
An important nuance is that The Advanced Flow will not repeat constantlyThe company clarifies that the complete activation, restart, and 24-hour waiting process will be applied as an initial flow per device and installation type; afterward, there will still be notifications and controls, but it will not be necessary to repeat the entire process from scratch each time.
This same approach will be extended to other Android devices, such as televisions with Android TV or Chromecast with Google TVIn these cases, you will also have to activate developer mode, confirm that no one is guiding you, restart and wait before installing apps from unverified developers, something that will affect those who used to load IPTV clients, alternative streaming apps or ad blockers on their TVs.
Why Google wants you to wait 24 hours: security and social engineering
Google's official statement focuses on a problem that goes beyond technical failures: social engineering and psychological pressureMany current scams do not rely on system vulnerabilities, but on convincing the user to manually disable protections and install malicious software.
Typical tactics include Calls that pretend to be from the bank, a technical service, or a public agencyThese situations create a sense of emergency. Under this pressure, the victim tends to accept permissions, ignore warnings, and follow instructions without pausing to read the messages on the screen.
With the previous system, in which Downloading and installing an APK was a matter of secondsPreviously, the scammer only needed to guide the victim step by step for them to trigger each warning almost without thinking. The new process aims to break precisely that pattern: forcing a restart, introducing a 24-hour pause, and requiring subsequent re-authentication.
Sameer Samat, head of the Android ecosystem, has even stated that That day of waiting eliminates thousands of fraud attempts.Their argument is that, in that interval, the person has time to check if the alleged problem with their bank account is real, talk to a family member, or look for information about the application they have been asked to install.
Google admits that This friction will also affect users who install legitimate apps.This is especially true for those who frequently use open-source APKs or projects from independent developers. However, he believes the overall balance is worthwhile if the number of victims of real-time guided scams is significantly reduced.
Verified apps, limited accounts, and the role of Play Protect
To avoid completely stifling the ecosystem, Google accompanies this new temporary wall with several figures designed to to differentiate between identified developers and anonymous creatorsThe first piece is the verification program, which requires developers to register with their documentation —such as a national identity card or other official identification— and associate their signing keys with a specific account.
When an app comes from a verified developerIn these cases, the system will not apply the full Advanced Flow. The installation will follow a path much closer to the current one: standard warnings about unknown sources and security checks will be maintained, but without the mandatory 24-hour blocking or forced restart.
In addition, Google is introducing calls "limited distribution accounts"These accounts are designed for students, hobbyists, or small projects. With this type of account, a developer can share their apps with up to 20 devices without having to go through the entire formal verification process or pay the $25 registration fee required to publish on Google Play.
In parallel, Google Play Protect reinforces its role as an additional layer of securityThis system continuously analyzes installed applications and can block or even uninstall those it considers potentially harmful, something that will be especially noticeable on devices such as televisions, where certain third-party apps modify system elements or block advertising.
For those who rely on third-party apps that may conflict with these policies, this will become increasingly important. Check your Play Protect settings from the device's Play Store and decide to what extent they allow the system to automatically act on software installed outside of official channels, as well as consult Key strategies to protect your devices.
What does this mean for users in Spain and Europe?
In the daily lives of many users in Spain and the rest of Europe, The direct impact will be limited if they only use Google Play. and other official stores. Banking, retail, social media, and messaging apps downloaded from verified channels will continue to install as before, without the 24-hour wall appearing.
The change will be most noticeable among those They usually install APKs manually Or they rely on alternative repositories like F-Droid, as well as those who use third-party stores linked to specific brands or projects. If the developers of these apps don't integrate with Google's verification system, their users will have to deal with the new advanced workflow.
This shift also comes at a delicate time in Europe, where digital regulations —including the Digital Markets Act (DMA)— This pushes major platforms to facilitate competition and give users more choice. While Apple has been forced to partially open iOS to sideloading in the European Union, Google is tightening the rules on this same practice in Android, citing security concerns.
Projects like F-Droid and some alternative app stores have criticized these measures, accusing Google of using malware as a pretext to progressively shut down Android and reduce the weight of the channels it doesn't directly control. However, Mountain View insists that the key isn't where the app is hosted, but whether its developer is identified and takes responsibility.
In any case, for the average user who only installs apps from Google Play, The change can go almost unnoticed.The problem will arise when, for example, someone asks you to install an external tool to "resolve an urgent problem" with your account: that's where the system will deploy its new barriers, including the 24-hour wait.
A backdoor for advanced users: ADB and advanced configuration
One of the major concerns following the announcement was what would happen to the so-called power usersThose who use Android in a more technical way, testing ROMs, installing open-source applications, or experimental tools outside of official stores. For them, Google has opened some avenues.
The clearest one is that The installation of apps using ADB (Android Debug Bridge) will not be affected due to the 24-hour waiting period. In other words, if you connect your phone or tablet to a computer—or use wireless ADB—and send an APK with the usual commands, the system will not apply the full Advanced Flow.
This makes ADB a kind of official escape route for advanced usersIt's not a resource intended for everyone, because it requires enabling USB debugging and handling a certain level of commands or tools, but that's precisely the profile that Google considers best understands the risks associated with sideloading.
On the other hand, those who wish to continue installing APKs from their own device can do so through an advanced setting hidden in the developer optionsAfter tapping the build number several times to activate this mode, you will be able to find settings such as "Allow unverified packages," select whether this exception is temporary (seven days) or indefinite, and explicitly confirm that you accept the risks, in addition to consulting essential tips and tricks.
This approach attempts to draw a clear line between the average user, whom we want to protect from hasty installations guided by third parties.And the technical user who, in theory, knows what he is doing and is willing to dedicate more time and effort to configuring the device to preserve that freedom.
The underlying feeling is that Android remains a more open system than iOS, but Each new policy introduces one more visible barrierThe ability to install apps from almost any source remains, although it will no longer be the quick and innocent gesture of downloading an APK and pressing "Install" in a matter of seconds.
The outlook for the coming months combines Greater protection against scams that exploit urgency The experience will be much slower and more deliberate for anyone wanting to install apps from unverified developers. Between developer mode, re-authentication, restarting, and the mandatory 24-hour waiting period, installing an external app will become a much more conscious act. For some, this will be a significant inconvenience, while for others it will be a layer of security that, although annoying, can prevent more than one unpleasant surprise.
