It's not private if it requires a Google account to use the feature. Edit: apparently you do not need a google account to use the feature, if so then I just hope it makes it into AOSP so we can use it on custom roms.
I just used it on grapheneos, it does recommend you use a separate Google account for the private space, but I don't have Google account on the phone, I was able to create a private space without any issue.
This feels very much like a second profile, like a workspace. So now you can have three profiles on your main phone login. Normal, private, work.
That's nice. I would have liked it if the lock button wasn't there, better to not reveal it at all.... Upon checking the settings, there is a hide option. So yeah this is great
I hid my private space, and now I can't unhide it. I have to go through settings to show it again. Supposedly you should be able to open it by searching for "private space". Might be a GOS bug.
This is perfect for banking apps, password managers, anything that you don't need to get notifications from
You need the G account to be able to install apps from Play Store, I don't believe the private space itself requires it.
Not sure if there's some Play "integrity check" on stock ROMs, but on GOS I was able to create the private space and download&install F-droid or other APKs just fine, without a Google account.
