Face ID stopped working when I dropped my phone—can I fix it?

💡 Need to know

• A cracked screen isn't required—Face ID sensors can be damaged even when your iPhone looks fine.
• Start with the basics—A restart, software update, or cleaning the TrueDepth camera may solve the problem.
• Setup failure is a clue—If Face ID won't let you enroll your face again, it's often a hardware issue.
• Time matters after a drop—The sooner you diagnose the problem, the better your chances of preventing additional issues.

You drop your iPhone®, pick it up, and everything seems fine—until Face ID® suddenly stops working. It's easy to assume the screen would've cracked if anything serious happened, but that's not always the case.

At Asurion, we help people troubleshoot phone issues every day, and we've seen plenty of drops damage the tiny sensors behind Face ID while leaving the rest of the phone looking perfectly normal. Before you assume you need a repair, there are a few simple things worth checking—and a few signs that usually point to a hardware issue.

Why would Face ID stop working after a drop?

Face ID depends on several tiny sensors working together with incredible precision. A hard drop can knock those components out of alignment or damage them, even if your iPhone doesn't have a cracked screen.

That's why it's fairly common to see a phone that still powers on, makes calls, and works normally—but suddenly won't recognize your face anymore.

Start with the simple fixes

Before assuming you need a repair, work through a few quick checks.

First, restart your iPhone. Temporary software issues can occasionally interfere with Face ID, and a restart is the quickest way to rule that out.

Next, make sure your iPhone is running the latest version of iOS. Software updates sometimes include fixes for Face ID and other camera-related features.

Then, check that nothing is blocking the TrueDepth camera system. A dirty lens, fingerprints, or even part of a bulky phone case or screen protector can prevent Face ID from working correctly. For iPhone cleaning tips, check out how to clean your phone the right way.

Try setting up Face ID again

If Face ID suddenly stopped recognizing you, try resetting it. Go to Settings > Face ID & Passcode > Reset Face ID. Then follow the prompts to create a new Face ID profile.

• If Face ID sets up successfully—the issue was likely software-related or caused by an interrupted setup.
• If your iPhone won't let you complete Face ID setup—or displays a message saying Face ID isn't available—that's a much stronger sign you're dealing with a hardware issue.

How can you tell if it's a hardware problem?

One clue we look for is consistency. If Face ID fails every single time, won't let you enroll a new face, and you've already restarted the phone and installed updates, software becomes much less likely.

The timing also matters. If everything stopped working immediately after a drop, the impact probably wasn't a coincidence. We've seen plenty of cases where the display survived the fall, but the internal Face ID sensors didn't.

What not to do

If you've already tried the basic troubleshooting steps once and Face ID still refuses to set up, continuing to reset it usually won't solve the problem. Instead, it can waste time that would be better spent confirming whether the issue is hardware-related.

We also don't recommend opening the phone yourself. The Face ID system is made up of delicate components that require specialized tools and calibration. A DIY repair can make the problem worse or permanently disable Face ID.

What if Face ID stopped working after water damage?

If your iPhone was recently exposed to water, moisture may have affected the sensors or internal connections that Face ID relies on. Before assuming the hardware has failed, follow these steps to help save a water-damaged phone and allow the device to dry completely.

If Face ID still isn't working after the phone has dried and you've completed the basic troubleshooting steps, it's likely time for a professional diagnosis.

FAQ

Can a drop break Face ID without cracking the screen?

Yes. Face ID relies on delicate internal sensors that can be damaged or knocked out of alignment even if the display looks perfectly normal.

Why does my iPhone say "Face ID not available"?

This message often points to a hardware issue, especially if it appeared after a drop or water exposure and restarting the phone doesn't help.

Can I recalibrate Face ID myself?

You can reset Face ID and create a new profile in Settings. If your iPhone won't complete the setup process, the problem is often hardware-related.

Should I keep resetting Face ID if it isn't working?

No. If you've already tried restarting your phone, updating iOS, and resetting Face ID once, repeatedly doing it again is unlikely to fix a hardware problem.

Can water damage stop Face ID from working?

Yes. Water can damage or interfere with the internal sensors Face ID depends on, even if the rest of the phone appears to function normally.
