I recommend grapheneos.org they offer regular and timely updates and offer a lot of very good security features such as contact/storage permission scopes (choose what contacts/files an app can access instead if being forced to allow all access or no access. I recommend at least giving it a look. I think you’ll love it if you want privacy and security. Have a look at the website, they offer way more than I have typed here. If you have questions I can answer them
