The Samsung Notes app keeps on crashing as of late I am currently on the latest one ui 3 beta update for the Note 20 ultra unlocked. Not sure if anyone else has encountered this issue and I'm not sure if this has to do with the beta update or not.
it works for me fine, when I first had issues I rebooted into recovery wiped cache, and then hit repair apps then rebooted, haven't had a lot of issues others have idk if that helped or not but there really nothing to lose if you try. Goodluck
seems to work rather well for me no airplane or turning off wifi mode etc needed, good luck I hope yours stays working as well
Please try the suggestions made by @betafishh . If the issue persists, please send us an error report. We apologize for the inconvenience and appreciate your contribution to the beta program.
