Facing exact same issue since day 1. UPI payment apps like PhonePe, GPay, PayTM work for 2-3 days, but unable to get the “enter pin” screen on 4th day. Rebooting is the only solution when this issue occurs. Other than this problem, the phone is great so far! I hope Nothing team takes this seriously as I highlight this problem to everyone who ask me about my Nothing 2 phone.
