Do you still have this problem? I also have this problem with my phone. I have 3 wired headphones, all 3 of them work just fine for my Samsung A51 but 2 of them don't work for my A22 5G only one that works.
Thank you for your response! Saved me from buying new headphones that not for Samsung. The headphones that work for my A22 5G are also the ones from A51 box. If I knew beforehand, it would be a deal breaker.
OK, I logged in to my Netflix with this phone. So far I haven't found any issue. What kind of issue do you have with Netflix on this phone? But I do feel this phone shows such ugly quality video if it's only HD (720p) or below in any platform whether it's YouTube, Netflix, Disney+. So I have to set it on Full HD (1080p) to watch it comfortably.
