anyone here with connector problem (in dock mode)?

[gameson]

I have a 4S that somewhat in dock mode once in a while with no reasons. I already cleaned the connector, and it's still doing that. I prefer not to replace my connector until I am absolutely have to.

Last night was the worst, especially if I play an intensive app like youtube or games, it will go from normal to dock mode. then after I put the phone to idle, then sound comes back again.

Anyone has tips?

Did you use a brush or blower or something that could possibly reach lint or other debris that could be stuck or causing the issue? I know you said you cleaned it, but I'm just asking.

Yes, I used long brush and also rubbing alcohol as well.
