How do I change the marked phone number for this device? I can't conduct UPI transactions due to this problem as I'm getting an error "your device is registered on another number"

Swear to god, if this is true, I'll be done with you Samsung. Rising cost!! You're one of the leading brands in smartphone market. And now Samsung feel the need to include ads, like some cheap phony rip off companies. Here's a suggestion, stop making...

So even after the new update on m30s..Tbe charging issue remains. Even with that fast charger, it's taking almost 2 mins, in an unit increase. Soo frustrating for a 6000 mah battery.Disappointed in samsung.
