+- K-iPhone – The one of the most secure Phones [IMHO](https://officercia.mirror.xyz/)❕
+- Solarin From Sirin Labs
+- Purism Librem 5 - Top-1 IMHO ❗️
+- Sirin Labs Finney U1
+- Latest iPhone (watch out [iCloud](https://www.quora.com/What-can-the-FBI-or-police-access-from-an-iCloud-account-Can-they-access-everything) & [known attacks](https://officercia.mirror.xyz/0uiAGM50rkQSvHbptcrVkCkyxsnewpAFIdu3oyga42Y)) or Android

+- Google Pixel (4 and beyond) are good privacy friendly options if you reconfigure them to run GrapheneOS!
+- Buy an old Nexus, run divestos.org or LineageOS or Ubuntu!
