Need help.
Wife Iphone 4 32gb Maxis set acting up. Camera tends to freeze and do not capture image, stuck at shutter screen not opening. Tried restoring the phone but problem still there. Any advice?

Dear All,
My iphone 4s is also water damaged but dried and repaired already can be used. Problem now is that battery deplete very fast, is this due to battery or main board, how do I check? If it is main board then I believe would be expensive rite compared to just battery replacement.
