Hey guys, I have a Google Pixel 8a Smartphone. It is a Degoogled Pixel 8a, currently with Calyxos. Is this the best custom ROM for privacy + security?
I also need to try to make it an Hardened phone. Not a Spy phone…not a Surveillance phone. Basically trying to make it an safe phone, anonymity phone.
What VPN could I use for this phone, and is there any other guides or settings guides you can recommend me.for my phone?
The sim card is a kyc one but im stuck with it.
Thank you.
Maby put your phone in a Cement for more hardening /s
Hands down the most advanced and secure smartphone os is grapheneOS.
It only runs on pixel devices. App sandboxing, buffer overflow protection, separate users, optional sandboxed google play if you need it for banking apps, automatic reboot after a set time to re encrypt your filesystem, assigning permissions for app access to folders and the list goes on and on.
I prefer Calyxos. over Grapheneos, hence, I’m seeking the most appropriate way to make my Pixel 8a Calyxos phone an Anonymity, a Safe phone.
I want the advice, and want to know what my options are if I stick with calyxos.
Also, recommend settings/configuration guides.
You did ask if it’s the best custom ROM. And the other poster did answer that question pretty well.
But honestly, what is your goal? If you want it to be a safe phone, just degoogle, install one of either Graphene or Calyx(dont ask me which one is better, I have no idea of either), dont install random apps you dont need, encrypt important stuff and you are good to go.
SIM tracking is another ball game, maby dont even have a SIM card. PIN lock your SIM card, only put it in your phone when you have to.
If you are looking for a hardened phone, I would consider trying GrapheneOS for a bit, see if it does what you are looking for. Uses SELinux and a seccomp-bpf policy for app sandboxing, as well as runs a hardened kernel with a hardened memory alloc. Great isolation approach, too, so that you can run apps on a ‘completely different phone,’ so to speak – think of the isolation like a small version of the OS that can keep apps entirely separate. Finally, if desired (and needed for certain apps), you can sandbox all Google services so that they don’t have direct access. It’s is a different approach to, say, microG.
GrapheneOS is all about hardening. Security is solid.
VPN wise, Mullvad wireguard servers are also solid. You can do multihops, which help you obsfucate traffic to degree. They have also been playing around with packet shaping (if you use their app directly).
Sim cards can be swapped out if use a VoIP service like jmp.chat.
What is the best thing to do with Calyxos smart phone for privacy, and anonymity. ? Like how to achieve this simply, and also, what VPN should I use if I stay with Calyxos in my Pixel 8A?
As a calyxOS user, if your key concerns are security and device hardening, I’d recommend you just make a seedvault backup and switch to graphene.
The two projects have somewhat different scopes and I don’t think you’ll achieve the same degree of sw security on calyx.

I feel that, I just wanted to set your expectations. I prefer and will continue to use CalyxOS but I have no expectation that they will deliver the same level of protections/mitigations at the OS side as Graphene given their project scope is different.
CalyxOS aims for a private, yet simple (attainable) Android experience, and I align more closely with their ideology on having a FOSS replacement for Google Play Services in MicroG.
I suppose one thing you could levarage is work profiles on Calyx to “jail” apps you do not trust, though I’m not sure that meaningfully builds upon Android 15s own application sandboxing.
Perhaps as a long term goal you could look into making a custom fork of CalyxOS for your device and incorporating parts of Graphene’s hardening but this will be a lot of work.
