I don't really have any issues as such. Everything runs fine. I got the Note 20 a few months ago. I get the carrier upgrades so I'm not sure if/when it went to Android 11 or if they were just updates. This is the only app I have on my phone that doesn't run at all.
I think the problem might be with your Android 11 OS. I have found various reports of people complaining that their apps freeze, crash, and fail to load after updating their OS to Android 11. Can you downgrade to Android 10 maybe? Or if you have a secondary phone with a lower Android version, try to install Electrum on it and see if it's stable. Have someone from your friend circle install Electrum if you don't have a secondary phone. Have you experienced issues with any of your other apps?
Just a few reports from users complaining about Android 11 issues:
I updated my S20+ 5g to Android 11/One UI 3.0 and while using apps, the phone freezes or closes the app or reverts to the previous page.
I'm also struggling with apps crashing and random reboots..
the same problem and nobody from Samsung is able to help.
It is unacceptable that after this Android 11 catastrophic Update the phone becomes almost useless and nobody is able to resolve the Issum.
S20+ owner.
It is unacceptable that a phone which has perfectly worked before the Android 11 installation, now after the update it gets almost unusable and noone is able to resolve the big problem!Samsung apps ( call, messages, gallery, notifications etc ) dont open, phone is warm, battery drained...
