Hello bro im currently using iphone 17 which I brought before 3days ago when someone was calling me the ringtone were glitching after i attended the call and Apple Intelligence were not downloaded when i connected to wifi which is mobile hotspot
hi bro, it is must to connect to actual wifi router to download apple intelligence files. make sure charge level is above 80% and then connect to wifi, it will be downloaded. Ringtone glitch issue could be temporary. try changing the ringtone to different sound temporarily and see if that fixes during incoming call or not.
