Hi @simong93

Did the friend say that the phone was cleaned correctly, and that any apparent corrosion and water remaining in the phone had all been removed?

If they didn’t say, then as you know water and electronics and electricity are not a good mix.

The impurities in the water causes corrosion and provides circuit paths for the electricity which were not in the phone's operating design and could damage the components.

First do not turn on your phone and then you need to, remove the battery as soon as possible from the phone to minimize further damage.

Then you need to dis-assemble the rest of the phone and clean all the affected parts using Isopropyl Alcohol 99%+ (available a electronics parts stores and some larger pharmacies), to remove all traces of corrosion and water. Do not use "rubbing alcohol" as in some cases this is only 70% IPA or less, can contain scents and is not as effective. If you do have to use it, check the label to verify the amount of IPA

Here is a link that describes the process.

Electronics Water Damage

As always with electronics, especially surface mounted PCBs be gentle when handling and especially when brushing away the corrosion. You do not want to remove any components from the board.

Hopefully after you have done all this the phone might possibly work correctly again.

If the digitizer (touchscreen) still doesn’t work after this, you may have to temporarily replace the display assembly to determine whether the problem is with the digitizer or on the systemboard and go from there.

Here is a link to the ifixit guide(s) for repairing your phone.

If this process seems too daunting, take your phone to a reputable, professional phone repair service, experienced in water damage repair and ask for a quote for a repair. If you decide to do this, do it sooner than later.
