This one is definitely the hardest and is the least mature. Have you managed to get off Google on your phone?
I’m using GrapheneOS (Degoogle’d android) on a Pixel 6a. The irony isn’t lost on me that I had to buy google to get off google.
I had tried Pinephone and Plasma mobile, but it still needs more work and I needed a phone sooner as my old one was failing.
How about you? Did you manage to get away from Google?
In the UK, banking apps are optional, I can use website in browser.
With GrapheneOS, you can install Play apps sandboxed and with dummied google apps and control how much of the file system they can see etc.
I would assume outlook has a web client. Not sure what InTune is so cannot comment.
Some yes, not all tho, doing it in a browser has more isolation but if you need to use the app you can also disable all permissions that “they need to properly function”, usually the app works but they are very hesitant in making you allow the microphone, contacts and camera all the time
InTune is mobile device management that allows a company to enforce policies on your phone such as pin code length/screen locking policies, and ability to remotely wipe your phone. Since these privacy ROMs are about giving control back to the user, I suspect that there will be problems with MDM enforcement software like InTune. I no longer work for a company that uses that software though, so no chance to test it out.
Ewww. No way would I install that on my phone. It would be on a work specific phone that I don’t give a crap about :). I doubt you can get much privacy on corporate mobiles with that shite :).
