I use Apps which need an additional account. Will Apps that are connected to an account (Google account or connected via e-mail) presumably work?
I also have an App which I payed for. I hope this information is connected to my account (Connected via e-mail not the Google accunt) to still have pro-version features?
Are there other ways to check if an App works on an alternativeOS before installing it?
Can I lock the bootloader again? (In general No, but with an FP3 persumably yes?) Should I lock the bootlaoder again? I am afraid to unlock the bootloader, failing the installing procedure or recognizing that certain apps I need don´t work anymore and not being able to revert to FairphoneOS or ending up again with FairphoneOS and an open bootloader. I would like to avoid ending up with an expensive paperweight.
I would appreciate some help!
PS: Sorry that this post is a bit chaotic. I searched the whole day and these are my open questions.
If you use apps that needed the play store then divestOS will not work. Some apps do work with a message (it need the play store), but some not work. And with microG this works.
What phone do you use? If it is the FP4 then CalyxOS is an option. If you have a FP3 then CalyxOS is not an option.
I have a FP3, and after some testing I find iodeOS the best choice (but that is because I have an app for stocks, etc (Peaks, and no alternative for it) that need the play store). I think DivestOS is the best choice if privacy is number 1, and you do not mind drop some apps or find alternatives for it.
But apps you payed for in the playstore cannot be used on any of these alternatives (if the payment is done in the play store).
But there is not really the best. It is personal. But like @SkewedZeppelin say … /e os is far behind security patches so not really a good choice.
On OSes which don’t have the genuine Google services there are no guarantees for Apps using Google components or being dependent on Google services.
Google-dependent Apps are not only obvious ones, they are rather the norm than the exception.
If you want to know about certain Apps, you can install Aurora Store. This is an alternative Play Store client with anonymous access (if you so choose), which displays whether an App is dependent on GSF (Google Services Framework) or not.
On an OS without the genuine Google services Google-dependent Apps might work without any trouble, or they might work with some trouble, or they might not work at all.
If they work without any trouble at a certain point in time, this is not guaranteed and can change at any moment.
microG greatly improves compatibility, but it is not a cure-all. It mimics the genuine Google services to a certain degree, but if Google change things on their side, at any moment this mimicry can break for a while or for good, and thus App compatibility can break for a while or for good.
The most promising combination for running Google-dependent Apps you really rely on to work on non-stock Android OSes to me seems to be
Android Custom ROM without microG
Open GApps (or similar projects, which all install the genuine Google services)
Google’s device registration for the use of Google Apps and services on non-certified Android OSes … https://www.google.com/android/uncertified/ … to not endanger your Google account with violating TOS (might be old knowledge, though, I didn’t have a look at this for a long time)
In theory, yes, but do be aware that they could be using different microG versions and that things may be fixed or break after microG updates (I was without TIDAL for about 2 months due to a microG update breaking it).
While microG is amazing in how much it can do, the fact that app developers simply don’t care supporting it and it’s a short-staffed project means things will sometimes be broken for months or longer. So if you really really need an app that needs Google Play Services (check out F-Droid if you don’t know about it for an app store of open source apps which don’t need Google Play Services) and not having access will negatively affect your life, I can’t recommend using microG. If you, however, are okay with sacrificing some apps for slightly increased privacy and freedom it can be really good option.
