Hello,

I am coming from Replicant and looking for something that will solve the upcoming problem of telecoms discontinuing 3G.

I understand that Graphene OS contains some proprietary components which seems inevitable with existing hardware.

Some of my questions are:

What particular analyses of the proprietary components have been made? What did those reveal and what protection measures have been implemented? In general, how does Graphene OS protect from potential malware in the proprietary components?
How does one replace the battery of a Pixel phone when the time comes? In case that requires a repair service, how is Graphene protected against someone tampering through physical access?
Will any of the planned for 2026/27 non-Pixel OEM phones, that Graphene will support, have a removable battery?
How does Graphene protect from side-channel vulnerabilities? E.g. can JS running in a browser do something malicious? (which used to be an issue when Spectre was initially found and probably still is on some CPUs)
Can unwanted apps be completely removed? (e.g. SIM Toolkit or Vanadium)
How does Graphene address the issue with apps requiring too many permissions (e.g. a banking app requiring access to camera which has nothing to do with e.g. checking one's balance or wiring a transfer)?
What is the way to use DNSCrypt on Graphene?
Is the warranty of a new device still valid after installing Graphene? Or is there a way to revert to the stock Android OS if not?
Can eSIM and SIM work together on the same device, if they are from different mobile network operators?
Which is/are the best Pixel 9 device/s in terms of security and privacy?
How does Pixel 10 compare to it?
How do the planned-to-be-supported OEM phones compare to the currently supported ones? (I am trying to understand how worth the waiting might be as I will need equipment for several people)

I hope this is the right place to ask.
