Water damage in faulty lifeproof and slightly ran over by fourwheeler

I had my new iphone SE in a life proof case and dropped it in water while getting ran over by an ATV. The case filled with water and mud. I immediately turned phone off. The phone was in water for an hour before starting the drying process. Put the phone in rice and slight heat for 5 days before turning on. The Phone works. Only things messed up are the rear camera, flash, horrible battery life, slight LCD glitches and maybe some service issues.. I have not tried any repairs and im new to the repair world. please help!!!
