My iPhone SE fell out on a walk and was run over. There aren’t any scratches but the frame is slightly bent so far it seems to be working fine but would a bent frame effect the phones function?
The risk with bent phones is permanent damage to the logic board. This could be damaged or broken solder balls/connections, damaged or broken copper traces on or in the logic board etc. If the phone appears to be working fine, you could try to remove the logic board and straighten out the housing or if the housing is too damaged, you could replace it. Either way, you have to expect that at some point, the phone could die or have a subsystem fail for no other apparent reason.
