how about this. My problem i think is similar with this guy.
I wanted to share my damaged iphone experience and offer a tip to help remove water marks from screen after exposing your iphone to excessive moisture. I was lucky enough to having my phone still operational after the water issue but had screen markings / dark spots from water. I was caught in a rain storm and ended up getting soaked, including my pockets which was where my phone was located. I decided to compile a few ideas I found online in 1 recommended tip. If your phone is not operational, you may just want to bag the phone in rice while powered off for a few days. This is for those people with water marks beneath the screen but phone is still working otherwise: 1. Go to settings>general>auto-lock and select 'never' 2. Go to settings>brightness&wallpaper and select auto-brightness 'off', then set brightness level to max! 3. Connect charging cable and place phone in a bag or container completely submerged in instant rice (uncle bens worked for me) 4. Allow a day or two of this drying out to occur and observe how the stains start changing and disappearing! I was amazed that this actually worked! The rice helped to pull the moisture out of the phone and the screen, being on , helped to generate enough heat which helped it dry out quicker. Definitely give this a try before spending up to $200 in insurance deductibles for a refurbished phone. Hope this helps, please feel free to share any other tips / ideas you may have. iPhone 5
you think will it help?
