Water Damage iPhone 4 sometimes shuts off after hours,

Hello.Recently I bought an Iphone 4 that was water damaged and the man that sold it to me said that the phone sometimes shuts off after couple of hours and that the phone was serviced not by apple but some other service.So the first thing I did was opening the phone because I noticed a low Wi-Fi reception....Turned out that most of the screws are missing and the the Camera's flash doesn't work...Do you have any suggestion why the phone might be shutting off, do you think that there might be a short circuit caused by the camera or the phone overheats cuz it gets pretty hot sometimes as far as I know the battery is changed and the shut offs happen rear like once or twice a day.The phone was water damaged some time ago so I dont know what the service and the owner did besides not screwing in some screws.

"besides not screwing in some screws." would show me some concern about the quality of repair that was performed. I'd start from scratch and disassemble the phone. Use this as your guide. Then clean the logic board with 90%+ isopropyl alcohol. You may have to repeat this a couple of times. Use this guide to clean your phone. It was written for a 3G but all the points still apply to your phone. After that replace the battery and all the screws There are some secondary functions of some of the screws, i.e. grounding etc. So you want to make sure that all the screws are in the order and the right place. After you got all this accomplished, reevaluate and see what you get. Hope this helps, good luck.
