My phone heating up no reason also keep changing to silent mode

Hello

I’m already taken apart my iphone 7 to change the home button that broken before (using third party home button with jumper) but after installation the new home button sometimes working and it sometimes not working (the phone also heating up no reason - iphone needs cooling down) now after i replaced the home button again with the original one (which doesn’t work) the heating issue has gone but now after restarting the phone always go to silent mode (i already check don’t disturb and also ringer) and now my silent switch doesn’t work at all (before replacing the home button with the jumper one the switch worked just fine)

I tried to replace the mute switch still the same result

Can somebody help me to give the information what’s happening to my phone ?

Thankyou so much

Check around J4504 (power FPC connector) and see if there are any diodes, resistors or filters that have been nudged.
