What to do when your iPhone6s dropped in water and the screen froze?

so yesterday i was taking a shower and i dropped my phone in the water. i also put a small plastic ziplock bag over it so it wont get water in it. i didnt know it dropped until i turned around. when i went to go pick it up the bag had water already in it. i was dumb to look not look if there was water inside it. then when i took it out i quickly wiped it with a towle. the screen turned black before. i started to panick. i then went to put rice in a bag with my phone. the phone started acting up and i didnt what was going on. then the next day, the phone kept on going on and off and on and off over and over again with the apple logo. i started to worry. then the screen came up and i thought it was healed. i press the home botton to go the password and... next thing you know the screen wont do anything. i let it aside a few hours later and some of the numbers can be pressed but most of them froze. later i started to google what to do and then the screen started pressing the numbers and it gave me like the phone is disabled signs and i was worried that if it continued it will shut my phone down. I dont know what to do anymore .

With water damage, you have to decontaminate the logic board before doing anything else, otherwise there will be latent issues down the road.

Not every water-damaged phone is recoverable and depending on the kind of liquid (salty, dirty, filthy), sometimes the success rate is quite low. That said, IMHO, it's always worth a try otherwise we are just piling up the e-waste.

The rice myth kills too many phones...

The water is inside the phone, on the logic board and under the shields, even under the IC's. The rice is nowhere near where the water is. So while it “may’’ soak up some water vapour, the real problem is the mineral deposits that can cause short circuits or the corrosion that is taking place as the water evaporates. Leaving the power on the device accelerates the process. The longer you let a phone sit in rice, the more time you are giving corrosion to damage your logic board. The saltier or harder the water is, the more damage will occur. The water needs to be displaced, not evaporated. Here’s a great video that summarizes these issues.

On some phones, rice treatments appear to work. But those are phones that had minimal water ingress and not anywhere near a danger area on the logic board. They would have recovered regardless of the intervention.

  • Open your phone and remove the logic board (follow this guide)
  • Inspect the logic board, especially around the connectors and look for corrosion.
  • Inspect both sides of the board. Unfortunately, most of the board is covered in shields. That's usually where the damage is occurring.
  • Put your board in a container with >90% isopropyl alcohol and let it sit for a while.
  • Use a soft brush, like a toothbrush and lightly brush away any corrosion you see.
  • Rinse in alcohol and repeat.
  • Let it air dry for a day.
  • Re-assemble and hope for the best.

You should also replace the battery if it has swollen. Resist the temptation to pop it to let the gas out. A compromised Li-ion battery is a fire hazard. If the device appears to power up but behaves erratically, then use a tool like 3uTools to flash the firmware as it may be corrupted.

A professional repair shop that does water damage repair may be able to recover your phone or the data because they have access to pro-level ultrasonic baths and specialized cleaners as well as the skills to troubleshoot your board. Many shops have a no fix/no fee policy so you don't have to spend money to find out if the phone is fixable or not.
