iPhone 15 Pro Max NOT VIBRATING

I can be on my phone, doing whatever… i close the app that I was using… oh i have a text message… MY PHONE DID NOT VIBRATE TO NOTIFY ME.

My phone is on this new “silent mode”…. Every previous iPhone I've owned has ALWAYS been on vibrate 100% of the time with no issues…. now with a new phone and new OS… the phone doesn’t vibrate at all…

It doesn't vibrate when I get a DM on insta or Facebook messenger like it used to.

i have “always on” selected under haptics, i have “vibration” turned on under accessibility, I’ve restarted my phone multiple times. Nothing works.

Yet on my iPhone 12 pro max, my text messages seem to vibrate JUST FINE.

I’ve even done a test. Placed both phones next to each other. While all apps closed and phones locked, I sent a text from my iPhone 15 to my iPhone 12… Buzzed as it should. Sent a text from my iPhone 12 to my iPhone 15…. NOTHING.

$1500 phone… I shouldn’t have an issue such as this.

FIX IT APPLE.

edit.

*** ANOTHER TEST I PERFORMED***

So on my iPhone 15 pro max, under notifications, then messages, i have all 3 notification styles(lock screen, notification center, banners) turned off for privacy at work.

Sent a text from my iphone 12 to iphone 15, SILENT.

On my iphone 12, I have all 3 notification styles turned on, sent a text from my 15 to the 12… it vibrated.

So it appears that APPLE needs to fix the issue where the phone will still vibrate, even with all 3 notification styles turned off, like it did on previous OS.
