Chosen Solution

I dropped my iphone 7 in a swimming pool and checked the liquid damage indicator which turned red. However, the device is working perfectly and has no obvious problems a few days later. Should I be worried or get it repaired??

@lydiafurner at this time I would sit back and see what happens. this “put it in a bag of rice overnight “ really doesn’t do anything. It is the equivalent of doing nothing. Your phone would most likely function just like it does now without the rice. May be the increased water resistance of the iPhone 7 saved your bacon on this one. If it received water damage it will usually manifest itself later. You can always see what the experts like @refectio think about this one. If unsure then I would recommend you send it to somebody that special with this type of “repair”

This is totally your call, but I would still strongly encourage backing up your device and get it inspect for liquid damage. Water damage may not present itself right away, but overtime the corrosion may damage the phone.
