I have the same problem - lens won’t fully close, camera turns off by going to sleep. Also, lens won’t extend all the way to 112, just to just past 85. And there is something rattling inside the lens. And since I tried fixing it by taking the lens barrel off and blowing on the lens, there is now stuff on the inside of the objective.
Apparently the only way to get to the lens is from in back, and that means taking the entire camera apart.
Otherwise the camera seems to work fine. I can’t see any defects thru the screen or viewfinder. It doesn’t even seem to affect battery life. I should try shooting some large pics and see if there are flaws I guess. I ended up buying an old model G1X as I need a working camera. But I really want this one back.
