The water-resistant Galaxy S7 and S7 edge feature a moisture sensor in the USB port

The water-resistant Galaxy S7 and S7 edge feature a moisture sensor in the USB port
Although it's not as important as the microSD card support and the larger batteries, water resistance is definitely a notable improvement that the Samsung Galaxy S7 and the Galaxy S7 edge bring over their predecessors. 

Given that the Samsung Galaxy S7 and the Galaxy S7 edge both feature IP68-certified water resistance, it's not surprising that Samsung warns about drying up the USB port of wet phones before feeding them electrical current. The Galaxy S7 edge user manual reads:


However, it was recently discovered that Samsung went beyond issuing a warning. The Samsung Galaxy S7 and the Galaxy S7 edge come with a special moisture sensor that prevents the phones from charging when humidity is detected in the charging port. If you'll try to charge it right after giving it a bath, the phone will pop an adequate message and refuse to charge. 

Interestingly, some early users say that this humidity sensor is actually so sensitive that third-party charging cables that do not adhere to Samsung's specifications can accidentally trip the warning.

Smart tech. Those little flaps on the S5 always end up breaking off anyways.

I beginning to be jealousy of S7 edge owners. This phone still has about 2-3 weeks to be available in my country. Can anyone tells me if it is really a dual Sim hybrid?

Yes it is, confirmed it with a Samsung rep. He said the SIM tray would be way too big if it wasnt hybrid since it would mean accomodating 3 different holes!

It does support dual sim? I thought it was sim/sd card only, not sim/sim. Guess I'm about to cancel my sd card pre order.

I just looked it up but there is a single sim version and a dual sim version. So the standard S7 (edge) won't feature dual sim http://gadgets.ndtv.com/mobiles/news/samsung-galaxy-s7-galaxy-s7-dual-sim-variants-get-certified-report-791682

Mine has yet to break, 2 yr later, but... I rarely open it with wireless charging... that being said, I'll be happy to not have it.

Wireless charging?

Its not wireless according to the experts. There is an invisble cord connected to the phone so the answer is no.

It's wireless because you don't have to plug anything into it. Yes the proximity has to be close to the charger. I'm sure people that have wireless chargers in the cars don't feel there's a wire going to their phone. No matter how good the tech gets there will always be a proximity distance to the charger for it to work. You're entitled to your opinion(propaganda) though.

According a few of Android experts and Apple experts on PA. Asvlong as the wire exist, there are no wireless charging.

But it's not plugged into the phone.

yeah right its all a big lie... wireless earbud isnt wireless since you need to plug cable to charge its battery. 4G also isnt wireless, since 4G BTS tower have gazillion cable connected to it. satellite isnt wireless since signal transmitter/reciever on earth connected to lots of cables... /s

I know. For them, the next contactless iPhone charger is the real wireless charger. Even thought in their homes, wire does still exists. Am I too dumb or are they too smart?

Those are ridiculous analogies... Wireless earbuds need not to be connected to the phone with a wire while in actual USE. The phone does not need to be attached to a cell tower to have cellular connectivity (sounds ridiculous). Satellites do not need to be attached to the ground station on the ground to be able to transmit a signal (sounds even more ridiculous). Hence, they are wireless. The phone needs to have CONTACT with a charging station (which is connected to a power source with a wire) to utilize induction charging, so basically wired charging.

I wonder if it also comes with a pressure sensor to detect if the phone is still sealed or not.

How about in very humid climates? It might trigger that sensor and not let you chrage it. Even if its not wet.

So you intend to charge in a sauna?

maybe....

Dampness and moisture is in almost everywhere in the air (there is no 100% dry air), so -of course- that sensor could detect many levels of moisture and decide If It should block the charging or not.

I've had to replace the port cover on my S5 4 times so I'm just glad they got rid of that, and without it I can finally use docks again.

If you're keeping it around much longer, get a wireless charging back and wireless charger. With those two things I rarely open my port and I'm still on the original ~2 yr later.

Samsung phones have always warned when you using a terrible charger. That's nothing new. But good for them because I can see some idiot coming out the rain and the battery is almost dead and they rush to the charger and plug it in like a dummy. Samsung is trying to make their phones idiot-proof. May be a good idea.

Yup, after the S pen issue last year they want their bases covered as best as possible.

Its not even an issue. Its because of dumb people

Whether is was the fault of Samsungs design or just "dumb people" as you say, it was still an issue. Please look up the definition of the word issue. Here is the definition from the Cambridge dictionary: "a ​subject or ​problem that ​people are ​thinking and ​talking about"!
