https://us.community.samsung.com/t5/Galaxy-S22/Samsung-S22-Ultra-Lost-a-Customer/m-p/2678197#M66612 I had same problem with S22U and after researching blogs and online, the conclusions I came to are; 1 SOME NOT ALL Qualcomm Gen 1 SOC has manufacturing problem with modem attachment, seems to detach under heat loads common usage, 2 Samsung learned about it and rather recall S22 series they just kicked the can til out of warranty. Resolution get trade-in discount on S23U with Gen 2 SOC, no connection issues at all. Sun, 01 Oct 2023 18:05:15 GMT EatApplesRockDroids 2023-10-01T18:05:15Z
