Hi Guys, looking for some expert advice. Ok, so I made a bad mistake and brought a 2nd hand iPhone 5S device from a private seller about 3 months ago. I brought the phone knowing the front-facing camera wasn't working but because the phone was still under warranty, I assumed I could get it fixed. Up to this point, i've had no issues with the phone. I took it into an apple store to get it fixed, but they informed me the phone had suffered water damage with its previous owner and wouldn't accept the phone. The question I want to ask is, in your expert opinion, is the phone likely to stop working anytime soon considering i've had no issues with it so far? There is no residual water inside now.
