Hi, Phone dropped in toilet for several seconds. I let it dry and then all was fine, just screen a bit dark. Then I took it to repair shop, they changed the screen and dried inside a bit. Then after this GPS not working properly, etc. Can I do something to check what is wrong in the phone/fix it myself? Thanks

there is possible damage under the gps chip, just drying it out wont get rid of the damage, it would be better it the logic board was taken out of the phone and ultrasonic cleaned. this might solve the problem depending on how bad the damage is
