Thanks. Same issue. Went on a 7 day trip overseas to a high humidity area and the phone didn't do well going from outside to inside climate-controlled rooms (air conditioning to outside). I have completed all the online steps to include removing the SIM Tray and looking for the water sticker (which does not appear to exist in my phone). Samsung does not have a walk-in service in the Washington D.C. area (go figure!), therefore I must send it in. It's still under warranty. You must factory reset, remove the SIM Card, and return it with the charger and head phones, but not in the original packaging. Samsung will send you a shipping label. If Samsung is unable to fix it, this will be an issue I will take into consideration for transitioning to an iPhone, unfortunately. No walk-in support to D.C. and a phone which is too sensitive for 110 degree to 68 degree temp changes is a product and the engineering behind it that I don't want to be a part of. We're paying too much money for something that should be resilient to all the temperatures available that a human being can live in.
Why is Samsung ignoring this issue!? Phone has NEVER been near water but if it dies completely it can't be recharged because of this moisture warning?? I've barely had this phone 6 months!!
I have now had the same issue twice within 2 weeks. First time it lasted for roughly 2 days and I set the phone in front of a fan. The warning went away. Not even 1 day later it happened again. Now going on 4 days with this moisture warning. Luckly I have the wireless charger but having to bring that bring thing everywhere is a pain. Please help!
