Ooo gosh. Always a bold move going from iOS to Android. What was the reason out of curiosity?
First question I always ask is - do you use an Apple Watch. As if yes, and you love it, you will NOT find the Pixel Watch to match what the Apple Watch can do.
I think it’s the gold standard of smart watches. Me personally, I don’t care for it at all, but I’m very much in the minority. People go crazy over the AW and if you find it integrates into your life well then you will likely go running back to an iPhone for it no matter how much you like the Android device you’re using.
The best advice I can give is give yourself time to understand Android. The Pixel is a great shout to move to as I think it’s very much the iPhone of the Android world. But you need to find time to adapt and learn the OS. If you only last a day and say it’s not for you then IMO you haven’t given it anywhere near long enough. Use the 2 week return period to make a full, informed decision.
Re cases, I always think Casetify do a good selection. But they’re expensive.
I’d recommend giving this video a watch. It’s a good introduction to Pixels (it is last years model, but the OS hasn’t fundamentally changed).
Good luck! Do post your thoughts!
