💌 YOU should switch to Open OS now! (+Why & How)

Whenever you boot you’ll start at EFIDroid, there you can select where to boot to. If you go to recovery you’ll get two options, for both OSes.

You can easily root your FP-OS phone. So I guess it should be possible.

Thanks for the guide, Paul.
After 11 months of FP2 OS (without any serious problems), this thread took away my fears of switching to Open OS and I did it.
I still think it is unnecessarily complicated to switch and I do not look forward to performing an update like in this thread.
Also I’m slightly disappointed in the amount of apps not being available for F-Droid, so for me there’s no way to use my Fairphone without Play Store. Many of the equivalent apps in F-Droid do not work or are complete trash compared to a lot of apps I use from the Play Store.
So the entire OpenGAPPS thing to me seems like an unnecessary workaround and makes me feel like this is really not the way things are meant to be.

Still, I’ll keep my Open OS because I like the idea. Have not run into a case where I’d need to root though.


You’ll only need to do that if you modify your system (e.g. install opengapps or xposed) and even then it’s not as complicated as that guide makes it look. Basically everything you flashed (installed via recovery) to modify your OS you’ll have to flash again after the update.

About the apps: You can use the Yalp Store (from F-Droid) to download any app from the Play Store without having to install all the spying Google Services.
I personally like the apps from F-Droid a lot. They are not as fancy as Play Store Apps, they don’t have such a polished design, but they do their functions just as well and usually with much less resources needed, as they don’t constantly run shady processes in the background.


I’ve tried to follow that but I can’t find efidroid in F-Droid. Is there something I missed here? Will I have to install access to play store to go in here?

There are many ways to get apps from the play store without accessing it directly:

As much as I like the Open OS I think one “con” needs to be added to the list:
For people that depend on some paranoid apps like electronic banking, Blackberry Work (see this thread) or Android Pay (well, for Android Pay FP2 would need a NFC chip first…), Open OS might not work


Good point. I added it.

Are there more or less random reboots with Open OS ?

I don’t have any (FP Open OS)

This is a hard question that probably can’t be answered, but here are my thoughts.

  • Open users usually tend to use less fancy apps, so (random) reboots caused by CPU straining apps are statistically probably less.
  • GAPPS tend to cause more issues than the lack of them, but than again I xould immagine installing them inofficially (OpenGAPPS) may make them even more error prone.
  • Updates that often improve the device stability come to Open OS later, so more reboots until then.

But to answer the core of your question: I don’t think Open OS is any more or less stable in general.

No reboots here, 2x FP2 on FP Open OS.

Thanks to the newly available TWRP with encryption support I recently took it upon myself to test the FP Open 17.02.0 release. I don’t use the Fairphone additions in FP OS and see most stuff as bloatware anyway, but I do want GAPPS included.

Preparations I’ve made:

Going to FP Open is simple as can be:
Go into TWRP, queue the FP Open and the GAPPS package and flash! Afterward you can re-enable encryption in the OS again.

Going back is even easier:
Restore the backup created earlier. Everything will be there except the contents of your /data/media (old internal storage / sd-card).

The FP Open is now my favorite ROM because:

  • It’s pre-rooted (go into developer mode and enable). I had to flash a rooted boot.img on FP OS (https://fp2.retsifp.de/) after every update.
  • Less bloated with launchers / apps I don’t use: iFixIt, Peace of Mind and other stuff is missing. It’s pure AOSP.
  • The camera has VVS protection built-in (https://www.youtube.com/watch?v=Bt9zSfinwFA)
  • I can choose the version of GAPPS. Pico has the bare framework and you can choose to install additions through the store (Calender, YouTube, Inbox for instance). The OK Google spyware isn’t included.
  • All the apps I use work under FP Open as well.
  • It feels as, or even more, stable as FP OS. But this can just be because the ‘fresh’ install.

Great topic :smiley:

Very intriguing. Is there for the Open OS also a testing branch for the upcoming Android 6 version?

Nope, there is not. From what I’ve heard, there won’t be one, because the code bases are very similar. Fairphone Open on Android 6 will come shortly after the release of Fairphone OS Marsmallow.

Is OpenOS affected by this behavior?

As far as I know, OpenOS without Google Play services (which contain the cloud messaging services that does this location tracking), is not affected. The same should hold for LineageOS.
