I walked into a river with my Iphone 6s and the water covered my phone just barely because it was in my pocket and the water was waist high. The phone was submerged for less than five seconds and i immediately got out and dried my phone off and set it upright on a dry towel to dry off. It worked fine after I dried it off and I let it sit for an hour (powered on) and tried using it before the screen went out and showed red, green and blue lines at random intervals when powered on. The processing of the phone was fine for a day or two afterward as I could send texts and call with siri by holding the home button. A few hours after I got home from my vacation the phone screen started working again and I tried putting in my pass-code and it got stuck on the last digit. Then I put the phone in a container with desiccant overnight and now it wont power on. As I type this it is still in the container with D-Desiccant industrial grade. I am wondering what to do to save the phone. My dad says he doesn’t want to open it up and the store we usually go to has already closed tonight and is closed tomorrow. What do i need to do to increase the chances of the phone being okay?
SGT Timez 1st thing would be to stop continuing to try to charge, sync or otherwise use your phone. This potentially can make a bad situation worse.This may further damage your phone. The next thing to do is to clean it. Disassemble your phone using these guides . You must remove all EMI shields. If you do not remove those, you might as well not do anything. After you removed those, clean the whole board, connectors and all with +90% isopropyl alcohol. Follow this guide , and even so it was written for a 3G all the points are still pertinent to your phone. While you clean your board, check for any obvious damage, like burned or missing components etc. When it is properly cleaned, replace the battery. All these steps are to avoid delayed failure caused by corrosion. Best thing to do would be to clean it with an ultrasonic cleaner, but if you do not have access to one, this will at least help. Once all this is done, reassemble your phone and reevaluate. Until it is cleaned, everything will only be a guess. It is possible that you have a bad LCD/digitizer and replacing the display assembly may fix it. Even with all this, water damage has only a small chance to be fully repaired, but at least you can give it a try. Since You want to wait until the store is open at least do not do anything with your phone. The desiccant will not remove the moisture from the logic board. It will not fix the phone. Do not touch it ;-)
