Selfie camera blurry and front camera shaking and making noise

Hi Vicktory,

It's a little unclear, but it looks to me as though there might be some damage to the front sensor array flex cable shown in the fifth picture on your question. Let me see if I can blow it up and point out what I'm looking at.

If that's the case, then the fix is fairly straight-forward; you'll just need to replace that front sensor/camera assembly. On the 8 Plus the only paired part restriction is on the home button, so you're free to swap out the front sensor parts without worrying something will stop working. Here's the part you'd need.

And of course I'd be remiss if I didn't also point you to the guide to making that repair, although given that you've already replaced the screen, you've done this once before.

Hopefully it's nothing more complicated than that, and your phone will be back in business shortly!

Your added picture does indeed look concerning.

I would not attempt to reassemble the phone with the connector looking like that. I would suggest you unplug it and make sure that metal backing plate isn't bent; if it is you'll need to straighten it. This is what happens when you try to plug it in by pressing on the middle of the connector rather than both ends, one at a time, especially if it isn't seated correctly and may be off by one or more pins so it's not fully seated.

So yeah, unplug it and make sure the backing plate and the connector are straight and the pins on both sides are undamaged. Then fold it over in place and use your fingertip to nudge it around gently until you feel it slip into place. Press it in place on one side then the other; you will frequently feel a slight clicking as it snaps in place, but not always.

At that point it should be sitting flat so then you can power it back up and test it before putting it all back together.
