Hello, I am considering de-googling my mobile experience. It seems like Samsung has bad security on their phones, which is why GrapheneOS is not available on Samsung phones, I guess. Ironically, google pixel phone is supposed to be the best fit for GrapheneOS.
So anyway, should I switch ? Ideally, I want to keep my phone. But my phone is quite old at this point, so I can consider buying a new phone. If I buy one, which one should I get?
Also, I heard call and mobile data does not work well on GrapheneOS and the like. How bad is it?
Samsung have great security, and the GrapheneOS team said multiples times that it’s one of the few manufacters that meet their security requirement. Unfortunately Samsung does not allow you to easily unlock the bootloader anymore and you CAN’T relock it after installing an alternative OS. This is the main reason why GOS is not available on Samsung device.
You can try LineageOS or /e/OS, both should have a build for your device but keep in mind that your security will be somewhat degraded. Your phone isn’t supported anymore anyways so it might be beneficial depending on your threat model. As LineageOS and /e/OS are way less bloated than Samsung stockROM you could benefit from better performance in several ways. I have revived a few device with LineageOS and DivestOS (RIP). If you buy a new one I would consider a Pixel 8A or 9 depending on how much you want to spend, they will benefit you from years of security updates.
From my experience I never had any issue with calls or mobile data on GrapheneOS nor any alternative ROM installed.
