I have been having the screen flickering issue with the nexus 7.  As shown on the youtube videos, I have opened it up and then taking out the battery plug ,and then plugged it back in, and then it works. For a couple of days.  Then i have the issue, and i do it over and over.  What i have seen is that the battery plug is NOT loose and still have that issue. Also I have slightly moved the battery closer to the plug so that the cord is no elongated.  Can someone help me with this issue?  My parents are going on a long europe vacation taking the device. I can correct this issue, but my parents will be unable to on their trip. Thanks for you help.
