Help Cant charge battery, camera fail, no menu/back option

[shellroc]

This may be a long story but here goes: First, I have a Samsung Galaxy S3, sch-1535, android version 4.3, kernel version 3.0.31, hardware version 1535.10, SE for android status permissive, software version 1535VRUCNC1 & no SIM card.
A friend gave me this phone after he got mud all over it.. It was showing green/black lines on screen.. I took it apart, cleaned it, and it worked,,,,somewhat.. the camera wont work, nor can I charge the battery, and now (this part worked before) I cant see the menu/back key option. (doesnt light). I have done a factory reset, and everything else imaginable.. I read a lot of forums, and they said I couldnt even get this far with it working.. I tried typing in the *# sequences, but nothing comes up.. Can anyone help me, PLZ??

Welcome shellroc
Well, to be honest, I think the corrosion from the moisture has finally done the phone in.
Unfortunately, when a phone gets moisture in it, if not tended to quickly, it's just a matter of time before failure.
In my opinion, I think the phone is not going to get any better

Agreed. About the only thing you can do is clean it again. Did you use 99% isopropyl alcohol to clean it?

As for cameras - you someplace have to replace those after a water damage clean up. They seem to toast out pretty easily.

no. I didnt use 99%.. but, I also didnt soak it in it.
