Dumdum "The Google Pixel 6, 6 Pro, and 6a are the most recommended. They have custom chips in the Tensor SOC to increase security and privacy, this article goes into that a bit. On top of the built in hardware security, the Tenor chips allow Google to support the phones for longer, with more OS upgrades and far longer minimum security updates, with 3 OS upgrades instead of 2 and 5 years of Security patches instead of up to 3. That makes the new Pixels much more secure for longer."
