Samsung Note 20 ultra uses the Lowest Quality of Motherboard which has max life of 1.5 year to 2 years. From last 20 days struggling to convey to Samsung team but nobody has a responsibility to listen to their Loyal customer (since 12 years+) 😵 I used almost every Galaxy Note since 12 years but I found Note 20 has Quality issue. 😕 Just want to convey to my friends before buying phone worth 1 lakh please see the post 🙏
Try changing SIM card. It may be defective or after few years, the contacts start eroding. My network stability improved after changing my 6-7 years old SIM card.
Also, I take it that your phone is Indian model (not region-locked). Those imported locked models may cause issues with SIM cards.
Finally, change network mode to LTE instead of 5G and reboot phone.
If none of this works, it maybe a hardware defect like you mention and needs replacement.
But posting the same stuff everyday on Samsung Members won't solve the problem. I don't think Samsung technical team goes through these posts, otherwise a lot of issues/pushing regular updates would have been fixed by now 😅 Especially, Samsung India is super-lazy nowadays.
