I bought the Oppo Reno 15 5G and wanted to know if it's normal for me to feel a slight vibration when I tap to repost a post and when I click on Instagram notes? I noticed that on the Oppo A96, I also feel the vibration when reposting and clicking on notes, but it's much less noticeable. I don't understand why. Can anyone explain to me why?
