I phone 6s plus not working
My I phone got caught with water and it`s not working, so after couple of days my friend recommended me to visit apple store to replace it with new device by paying some certain amount.
iPhone 6s Plus, iOS 9.3.2
Check the Liquid Contact Indicator as noted here > Liquid damage to iPhone or iPod isn't covered by warranty - Apple Support
If liquid damages an iPhone or iPod (for example, coffee or a soft drink), the service for the liquid damage isn't covered by the Apple one-year limited warranty or an AppleCare Protection Plan (APP).
Apple will not replace your iPhone due to water damage. You will have to pay full price for a new one.
