Vibration doesnt work accept home button

Vibration is only working in home button feedback but not in other cases like the system wide haptic feedback or vibration on ringtone.

i severely broke my phone & had to change the casing by placing my motherboard onto another iphone 8 plus casing which was icloud locked.

After that I’m facing 4 problems

1. Haptic feedback works only on home button (tried changing setting and restore iphone)

# No airpod prompt when I open the lid, cant connect it instantly, gets disconnected often

1. low wifi range
2. Most often only 2 bars in cellular network indicator.
3. can anyone suggest me a fix?
4. thanks in advance
