Yeah I don’t get what the issue is with notification sounds.

I’m not sure what it is, but ever since I got a more modern phone, the vibration motor has just gotten so weak compared to older phones I’ve used. I legitimately do not feel my phone vibrating in my pocket.

So when I’m at work, if I’m expecting a message, I actually have to turn the sound on and listen for it as opposed to feel it vibrating. I hardly get any notifications tho.
