Pixel 7 Gets a Big Update With Free VPN and AI-Enhanced Call Audio
(made in china, runs california based android, a very nice phone but almost as high prices as Apple)
Google Pixel 7 uses it's own Tensor chip technology as well as their own Android, and has well spec'ed hardware.
samsung: exynos (made by samsung), snapdragon (usa patented made in taiwan tsmc, Mediatek - a chinese maker maybe printed at tsmc)
apple silicon: made at tsmc taiwan. mostly just android. but has "extra layers of billions of circuits" that significantly improve over other chips.
other choices: chinese huawei and about 300 renamed cell phones which "all are different slightly" hardware and unsupported once bought. Huawei has models with their own chips in sometimes. they use about anything except exynos and A13.
