better than Google calendar but has bugs/for example it keeps restoring deleted events after i delete them/i cleared cache memo and restarted phone/useless/still the same banana. update/yes i did remove Gmail account but no use/it seems a bug between localhost and oppo accounts as it shows both colors for the same birthday/btw i tested removing oppo account or localhost then i get a bug free part of the calendar but it bugs again after that part. update/yes 2 entries but for a certain period.
