You must not be knowing that your iPhone 6S Plus is so powerful.
W hat if water spills over your mobile phone You will obviously panic. The phone will stop working. The world will come upside down. ''What has happened Oh my god! Oh my god! God help me! I swear I will take care of it from the next time. Please save me this time.''Lol! This must have happened to each one of us at least once in our lifetime. But what if I tell you that your phones can survive not only water but also freezing and coca-cola I am sure you won't trust me but still have a look, try this and I bet this would change your mind.
The Samsung Galaxy S7 Edge is water resistant though, but we didn't expect the iPhone to come back to life.
