Hi
Right we have to act fast! It’s a race against time
1 take it out of the rice it’s going to make it worse with all that starch
2 turn it off if you can
3 go to your nearest store and get distilled water and rinse the iPhone carefully
4 go and get a pentalobe screwdriver or take it to a authorised phone repair shop and ask them to take the screen off
5 unplug the battery no dowse the iPhones insides with isopropyl alcohol but don’t get any in the screen
Once you have done this Wait 48hrs and hope for the best!
Hopefully all goes well if it doesn’t tell us and we will tell you the next steps!
Thanks:-)
