Hi there,
In answer to your question on Samsung e700...
The faults that you are experiencing are due to the cable that links the two parts together being damaged due to open & shutting the clam..
Progressive faults that will occur are; "camera preview error" on screen and then the inner screen will go off or go white.. This is as cable damage becomes worse (or worn)..
Only way to rectify this is to replace cable...
Its a very common fault of the e700 and most clam-shell phones...
Hope this helped..
