IPhone 7 not charging following previous toilet plunge and dodgy USB cord- coincidence or water damage?

My apple charger has always been a little dodgy and decides to charge when it wants to (on brand charger that came with my device). I dropped my iPhone 7 plus in the toilet about three days ago. It had, had no side effects, glitches, or any noticeable damage and was charging completely fine. Last night it randomly decided to stop charging. I have tried all of my off brand chargers, although I know that apple is picky with their chargers, and my one on brand charger with no luck. I suppose what I'm asking is, do you think this is just a coincidence and the charger finally gave out? Or is it normal to experience water damage effects several days following the incident.

Is there a way a person can track an iPhone online?

My dad's iPhone was apparently stolen and he asked me if I can track it down for him. I don't know where to go to do this. I don't use an Apple phone myself, so I can't download the 'find my iPhone' app to locate it. What do I do?

How do i get my money/phone of i got scammed with a friend using PayPal accounts?

Basically i was looking into getting a new phone, and around my friend he had someone order me a new IPhone 6S+ off Sprint and i only gave him half the money for the phone based off the sprint website so i paid 275$
. Last Tuesday they said the phone arrived and someone has signed for it. I've asked for the tracking emails but haven't gotten any to view so the only email i have as evidence to the transaction is the email that we both received after he placed the order. So it's been a week and i haven't seen a phone come through the mail and they say it's been signed for so I'm out of 275$ so far & still need a phone. I really would just like the phone i wanted but would rather get my money back to not be left with anything.

My IPhone back face microphone is muffled?

So I was recording a YouTube video y'know and after recording 3 minutes of footage, I checked it and noticed that my voice is muffled. At first, I thought it was my app acting up so I decided to record with the regular Camera app and realized that it's my microphone that is the the problem. My front face microphone is working fine but the back face one is a different story.

How do I fix this? This is an IPhone 7 by the way with IOS 11.2.2.

Can't mute the camera sound in new iPhone 6?

Just got a new used iPhone 6, and can't mute the camera shutter sound. Mute button doesn't work, and when I try and adjust volume all it does is just take more pictures and make more noise. Have checked camera settings and sound settings and there seems to be nothing.

IPhone 6 No Service issue?

My iphone has stopped getting signal, although I can still search for and see carriers in Settings>Carrier, so I'm wondering if it may not actually be a hardware issue if it's still half working.
So far I've updated my iOS, reset network settings, replaced the sim, and done a factory reset. Nothing so far, any advice or ideas anyone might have would be greatly appreciated!
