My note 10+, note 20U, and S 20U all suck on low signal. My fold 2 keeps on trucking in the same areas the above crash.
I have my WiFi calling turned off. I pay Verizon to provide my calling service, not my internet company. I'll turn wifi calling on if I'm like on vacation in the woods and need it, other wise Verizon can provide the service I pay for. Verizon and other carriers are good at passing the responsibility of what they sell onto other companies, such as data. It's actually genius of them to do that, sell a service and encourage you to use another provider services to get what you are paying Verizon or any carrier for. I'm sure WiFi calling is being implemented for 5G as 5G has less coverage.
Anyway, following to see if I get any real answers from real situations, not in the city if Samsung has improved their signal issues yet. They got it on the fold 2, don't understand the notes and S 20U issues. I travel, and the fold 2 is the only one that won't drop calls in the same exact areas the others do, I can tell who I'm talking to with the others right when I'll be calling them back, fold 2 keeps going. So it's not a carrier issue, it's Samsung.
