hi there, l am having the same problem or at least a very similar one. lm not familiar with computer system so pardon for any inaccuracies.
what l experienced was stutters in various apps , youtube , Samsung music, and other video applications as well. the stutter happens extremely frequently , around once per 3 seconds. it happens during videos as well as music tracks, and the stutters appears when lm not using bluetooth either.
this problem is extremely annoying and l cant use my phone for any video or audio entertainment .
l just started experiencing this today and l just found this post. l didnt submit any report yet to any samsung support.
l have tried multiple solutions l found online that for similar situation, including rebooting my phone, reinstalling youtube, clear youtibe cache, force stop youtube. however nothing worked.
l hope this issue will be fix soon. please let me know what else can l do to solve this problem.
