Camera and led not working huawei p9

Recently, i broke the screen and had the LCD digitizer replaced by a local guy. Upon replacement, the screen itself did not sit completely flush and there was a small glimmer of light that you can see through the side of the digitizer; no biggie all seemed to be fine.

however now the LED does not work (i open the flashlight app and nothing happens), Nor does the camera app work. When I open the camera app, the app dies and doesn't open. When i try an app that would USE the camera, there is an error message saying "the camera is in use by another application".

So-- I'm unsure if the camera or LED worked prior to replacing the screen. I honestly didn't think to check. The screen was damaged pretty badly.

Ideas.?

I have called Huawei US and as this model (the p9) is an "International model" they (Huawei) will not help. Which is weird. but alas true.

I know that this phone is not in the US yet, but it seems that if I can't fix it, it is a big risk to buy another knowing that if I break the screen, im screwed.. any ideas..?
