The front camera doesn't work after replacing my iPhone 5 lcd screen. The camera app opens, but when I try to flip to front camera it is a black image and the camera freezes.How does this happen?
There are a number of factors that can contribute to the failure of the front camera/ proximity sensor/ambient light sensor.
What I would do is first check if the connector is properly seated on the socket itself. Usually it snaps into place. Next, I would check the pins on the connector and the logic board itself. Usually, the tiny gold pins on the sockets can be damaged from forceful installation of the connectors, which is not good. Always always always remember that if a connector does not want to snap on to a socket, do not force it or else damaged will be ensued. It has happened to me before.
Next I would check the installation of the camera/sensors on the screen. Was the camera lens holder and ambient/proximity sensor gasket transferred and properly seated onto the new screen? Are the screws present and properly torqued down on the earpiece bracket? Over tightening can cause damage and other problems. Is the earpiece and its bracket properly installed?
Lastly, I would check the flex cables themselves. Are they pinched or severely folded? This can potentially cause problems. The flex cables should only be formed in round or U shapes. The flex cable that connects the ground copper sticker on the back of the screen shield is an exception since it already comes looking messed up.
I'm not too sure if the copper sticker that sticks to the back of the screen shield would make a difference. I have gotten the camera and everything else working without it. However, I do suggest that you do reinstall it since it seems like it acts as a ground to complete the circuit.
Forgot to add one more thing. Restoring your phone would more than likely not do anything. It's usually not software related but if you do feel very confident that a restore would perhaps fix it and you backed up all your data, then by all means go for it.

How to Fix Your Black iPhone Screen?
Your iPhone is on, but the screen is black.
Your iPhone rings, but you can’t answer the call. You’ve tried resetting your
iPhone, letting it run out of battery and plugging it back in, and your iPhone
screen is still black. In this article, I’ll explain why your iPhone screen
went black and what you can do to fix it.
A black screen is usually caused by a
hardware problem with your iPhone, so there usually isn’t a quick fix. That
being said, a software crash can cause your iPhone display to freeze and turn
black, so let’s try a hard reset to see if that’s what’s going on.
To do a hard reset, press and hold the
power button (also known as the Sleep / Wake button) and the Home button (the
circular button below the display) together for at least 10 seconds. If the
Apple logo appears on the screen, there probably isn’t a problem with your
iPhone’s hardware – it was a software crash. You can find a quick solution to
this software crash problem by searching on the net. If the Apple logo doesn’t
appear on the screen, keep reading.
Why
Is My iPhone Screen Black? Let’s Look Inside.
A brief tour of the inside of your iPhone
will help you understand why your screen is black. There are two pieces of
hardware that we’ll talk about: Your iPhone’s display and the logic board.
The logic board is the brains behind the
operation of your iPhone, and every part of your iPhone connects to it. The
display shows you the images you see, but the logic board tells it what to
display.
The entire display of your iPhone is
removable, but it’s a lot more complicated than you might think! There are four
major components built into your iPhone’s display:
1.
The LCD screen, which displays
the images you see on your iPhone.
2.
The digitizer, which is the
part of the display that processes touch. It digitizes your finger, which means
it turns the touch of your finger into a digital language your iPhone can
understand.
3.
The front-facing camera
4.
The home button
Each component of your iPhone’s display has
a separate connector that plugs into your iPhone’s logic board. That’s why you
might be able to swipe across the screen with your finger, even though the
screen is black. The digitizer is working, but the LCD is not.
In many cases, your iPhone screen is black
because the cable that connects the LCD to the logic board has become
dislodged. This cable is called the display data connector. When the display
data connector becomes dislodged from the logic board, your iPhone can be fixed
by plugging it back in.
There are other cases where the fix isn’t
so simple, and that’s when the LCD itself is damaged. When that happens, it
doesn’t matter if the LCD is connected to the logic board or not – it’s broken
and it needs to be replaced.
How
Do I Know Whether My Display Is Dislodged Or Broken?
I’m hesitant to write this because it is by
no means a hard and fast rule, but I have noticed a pattern in my experience
working with iPhones. There are no guarantees, but my rule of thumb is this:
l If your iPhone display stopped working after you dropped it, your
screen is probably black because the LCD cable (display data connector) has
become dislodged from the logic board.
l If your iPhone display stopped working after it got wet, your screen
is probably black because the LCD is broken and needs to be replaced.
How
To Fix A Black iPhone Screen
The way you choose to proceed may depend on
whether your iPhone LCD cable has become dislodged from the logic board or if
the LCD is broken. You can use my rule from above to make an educated guess.
If the LCD cable has become dislodged, the
Genius Bar at an Apple Store may repair it free of charge, even if your iPhone
is out of warranty. That’s because the fix is relatively simple: They’ll open
your iPhone and reconnect the digitizer cable to the logic board. If you decide
to go this route, make an appointment with the Genius Bar before you arrive –
otherwise, you could end up standing around for a while.
If the LCD is broken, that’s another story.
It can be very expensive to repair your iPhone display, especially if you go
through Apple. If you’re looking for a high-quality, less-expensive
alternative, I recommend iCracked.
Repairing
Your iPhone Yourself Usually Isn’t A Good Idea
iPhones aren’t meant to be opened by the
user. Just take a look at the two screws next to the charging port of your
iPhone – they’re star-shaped! That being said, there are excellent repair
guides out there if you’re feeling adventurous. There is a repair guide article
on iFixit called “iPhone 6 Front Panel Assembly Replacement”. Here’s a brief
excerpt of that article that may sound familiar:
“When reassembling your phone, the display
data cable may pop off its connector. This can result in white lines or a blank
screen when powering your phone back on. If that happens, simply reconnect the
cable and power cycle your phone.”
If you believe your iPhone LCD cable
(display data cable) has simply become dislodged from the logic board, you’re
very tech-savvy, and going to an Apple Store isn’t an option, reconnecting the
display data cable to the logic board isn’t that difficult, if you have the
right tools. Replacing the display is very complex because of the number of components
involved. Let me be clear: I do not recommend you try to fix this problem
yourself, because it’s just too easy to break something and “brick” your
iPhone.
You
Know What You Have To Do
Most readers won’t be able to fix their
iPhone screen just by reading this article, because a black iPhone screen
usually isn’t caused by a software issue. Everything was working fine until
your iPhone screen went black. Now you can’t use your iPhone at all, but you do
know what to do next. I’m interested to hear how you fixed your iPhone in the
comments section below, and any experience you can offer will undoubtedly help
other readers with the same problem.
