2 bugs in iphone 13 pro max

I am loosing my mind. My phone is brand new 13 pro max, bought in Brooklyn and worked amazingly. For allmost a month and a half my led component stopped working. No flashlight. No camera flash. Also, whtsapp notification stopped working too! The whatsapp icon not even showing on the app list within the settings. I tried everything. It is on ios 15.2 now, i was resetting all the setting,network settings, hard booted it, and nothing seems to help. Im begging for help
