The killing features on Samsung Galaxy S5 that people love most that was removed on S6 was the ability of the device to resist water.
The noticeable plastic ruggedness on S5 was then replaced, making the device sleeker, additional elegant in its design. But Galaxy S7, the company managed to resurrect the best words of them, delivering gorgeous looking with functional utility that is provided by the IP68 certification.
So in order to shield the phone, the company built a world class device safeguard that will be triggered when waters water are spotted in the special micro USB hole. Upon detection the phone immediately shows a warning message that will warn the user to prevent the handset from it to avoid device malfunction or may result to fry.
So it seems that this new Samsung feature was somewhat a handy device warning, but out of curiosity some user reported with his personal experience with the device after using it for few hours on an underwater shoot trigger the device to disable its charging feature, showing a warning message, even the phone was dry. So what the user did was removing and putting back again the battery but after charging there was no sign of fast charging of the device in happens normally as per system default.
