No. As of November 2026, installing Fluxer from our Android download page, from GitHub or with Obtainium works the same as before, in every country. Google plans to check apps installed this way on certified Android phones in 2027, and we plan to register Fluxer with Google before then, so that these installs and updates keep working.
What is Google changing?
Google is adding developer verification to Android. On certified Android devices, which are phones and tablets that come with Google Play services and pass Google's certification, apps will need to come from a developer who is registered with Google, or you'll need to take a few extra steps before you can install them on your phone.1
Does developer verification affect me today?
No. Since 30 September 2026, Google checks apps only when you install them from certain app stores, such as Google Play and Samsung's Galaxy Store, on certified devices in Brazil, Indonesia, Singapore and Thailand.12 Google's FAQ says the checks "won't apply" yet to apps that people install directly,3 and that includes the Fluxer APK you download from our website or GitHub, or install with Obtainium, in every country.
What changes in 2027?
Google says verification "will be expanded globally for all apps on certified Android devices in 2027", and it hasn't said in which month yet.1 From then on, a certified phone will only install or update an app from an unregistered developer if you use Google's advanced flow or install the app from a computer with a tool called ADB.
What is Fluxer doing about it?
We plan to register the Fluxer app, com.fluxer, with Google before the 2027 rollout, together with the key that signs the APKs on our website and GitHub. Google lets a developer add more than one signing key to a registered app,4 so the APKs and the version on Google Play can both be registered. After that, you'll be able to install and update the Fluxer APK on a certified phone without any extra steps, the same as today.
Google registered almost every app on Google Play automatically,5 and the Fluxer app on Google Play installs with no extra steps, the same as other apps on Google Play.
What if my phone has no Google certification?
Google's checks apply to certified Android devices, so phones without Google's certification are most likely not affected. That includes phones running GrapheneOS or LineageOS without Google Play services, although Google hasn't said anything about GrapheneOS by name. A phone that still has Google Play services installed is most likely a certified device, even if you've removed most of the other Google apps from it.
How do I avoid any extra steps?
You won't need any extra steps with the Fluxer app on Google Play, and you won't need them with the APK either once we've registered it. You can't switch between the two without reinstalling Fluxer, because they're signed differently.
What are the advanced flow and ADB?
They're the two ways that Google keeps for installing apps from unregistered developers on a certified phone. The advanced flow is a one-time setup where you turn on developer options, restart your phone and sign in again, wait 24 hours and then allow apps from unverified developers for seven days or with no time limit. After that, each install shows a warning with an "Install anyway" button that you tap to go ahead.67
ADB installs an app from a computer over USB, with no waiting time.7 You'd only need either one for the Fluxer APK if our registration wasn't done in time.
Can I get Fluxer from F-Droid?
Not yet, but Fluxer is coming to F-Droid and Accrescent soon.
