There are so many reasons, but the main one is that they keep pushing their shitty Exynos cpus in Europe! My next phone is certainly not a Samsung just for this reason.
It is, and it's the reason Pixel 6 and 7 series had so many issues with poor battery life and weak modem. Although it appears that the third generation Tensor CPUs in Pixel 8 have major improvements on both of these pain points.
Still, that probably brings Pixel 8 only to the cheap-ish midrange standard when it comes to cell signal, as the Pixel 7 phones were atrocious and 6s were apparently even worse.
