    My wife has her SGH-I337 with Android 4.4.4 on AT&T getting the "no SIM detected message" with a known new working SIM and a newly replaced SIM + microSD card reader installed.
    This may or may not be related to some small amount (less than 5 ml) of water getting into the phone next to sink a week before.
    Phone was working OK for a week after the water incident and a new SIM from the local AT&T Store.
    Moisture sticker on battery is still white. Moisture sticker in case is pink.
    Phone was sealed in can of baked out silica gel for 2 days to draw out any remaining moisture.
    I used the SIM from her S4 in my S4 and it's working.
    Also, the touch sounds and the boot screen sounds are distorted and garbled, but the music and media sounds are fine.
    Did hard reset and also booted this S4 into safe mode, and still no SIM is detected message is appearing.
    Can read microSD well. Display is working well, WiFi all buttons, contacts look good inside, just reading SIM and distorted touch sounds.
    All that I can find online is to take motherboard out and clean any suspicious gold contacts with 91% isopropyl or even to replace the motherboard, but that is pretty expensive. I am looking to find what other contacts are involved in the SIM card reader that might prevent it from connecting to the logic or the processor.
    Please let me know if you have any ideas or suggestions to get this SGH-I337 back on the AT&T network.

    Welcome to Android Central! That's going to be a challenge, since water damage can be insidious and can progress over time. You might not be able to pinpoint one specific area of damage. See this guide: http://forums.androidcentral.com/amb...e-got-wet.html

    Hi, I am the poster of this question. Thanks for the guide. That all makes sense to a guy that worked in a wet chem lab for 5 years. I am trying to locate the part of the logic board that might have corrosion or bad contacts now with 91% isopropyl in hand. about 2 weeks have past since the original moisture incident. So far in replacing the SIM card reader , all contacts I saw on that side of the logic board looked fine, so I will look at the flip side tonight.
