Q: Iphone se water damage

Yesterday Night i drop my new iphone se into glass with full of water. it stays in like few seconds. when i took the phone screen start giving strange colors and finally color mixed and nothing can seen. however i managed to turn it off immediately. after turn off i kept it in rice for 20 minutes and i turn on and check the phone. it was functional and looks like nothing has damaged. but water was still leaking from lock button. so i turn it off and kept in rice for over night. next day morning i open it and found that many white line on the screen and camera with flash not functional. so i put the phone in window for 6 hours and check the phone. screen was ok, but camera still show black screen and flash also not working. so i kept there another 2 hours and turn on. everything functional. camera, flash nothing has damaged. love this phone.
