I recently bought my wife a Samsung Galaxy S8 SM-G950U (Unlocked by Samsung). Purchased from Amazon. The phone technically works with Verizon, but it seems that it only has partial compatibility with Verizon's CDMA network. I don't totally understand but from what I gather, it works well when it has 4G LTE signal, but really has problems with lesser signals (3G, 2G, 1G). It seems like it has no connection (no calling or data) when it's out of 4G LTE range. Her old phone (HTC 10) seems to have much better compatibility with Verizon's CDMA signals. She really likes the S8, but the importance of her ability to use voice calling outweighs the other benefits of the phone upgrade, so we're going to return the Galaxy S8 and she's going back to the HTC 10 until we find something that works better with Verizon's network.
So now to my questions:
1) Is there a version of the Galaxy S8 that has better network compatibility with Verizon?
2) Are there other Galaxy phones that work better with Verizon's CDMA signals?
3) Can you recommend any other phones that are known to have great compatibility with Verizon? (Google Pixel? any others?)
My goal is to get her a premium phone that is maybe 1-2 years old, but works great with Verizon. It doesn't have to be Samsung. Thanks in advance
