Raiffeisen e-banking and Twint work perfectly for me. There are also no problems with Netflix. All the apps I used on my iPhone also work on this S21 Ultra Snapdragon without any problems. Except for the use of Samsung Pay which does not work with my Raiffeisen card. But I think that's more down to my bank than the smartphone. The same problem was also present with the iPhone.

Brilliant, wow! Thanks for the prompt answers! I wonder why they buy or sell the Exynos version outside the usa.
For me, that means switching to the Snapdragon version! I'm not a fan of Samsung at all. But if you want a great camera and a reasonably good battery, you're stuck with the Snapdragon version of the S21 Ultra.
Huawei is unfortunately no longer without Google Services, I'm done with the tinkering. Otherwise, with Oppo (too expensive for a still underdog) and OnePlus 9 Pro (various software problems), there is nothing left. Sony 1 III is still to come, but I don't have high hopes for it ... and the new Pixel is coming onto the market too late. Even though it has the greatest potential with its own SoC etc.. Although everything is again in "cooperation" with Samsung, it is developed for Pixel.

Unfortunately there is nothing good... And I'm definitely not switching to the Apple sect.
