If you've been jumping into the game lately and wondering why the pet simulator 99 face id working isn't happening for you, don't worry, because you're definitely not the only one dealing with this glitchy mess. It's one of those features that sounds incredibly cool on paper—having your avatar mimic your real-life facial expressions while you're grinding for diamonds or hatching eggs—but in practice, it can be a bit of a headache to actually get running.
One minute you're laughing at a joke in the trading plaza and your avatar is smiling along with you, and the next, your character is just staring blankly into the void like they've seen a ghost. If you're trying to figure out how to get everything synced up again, we need to look at a few different things, from your Roblox account settings to the actual device you're playing on.
What's the deal with Face ID in PS99?
Before we dive into the "how-to," let's talk about what this feature even is. Roblox introduced dynamic heads a while back, which allows for camera-based facial animation. Since Pet Simulator 99 is one of the biggest games on the platform, Big Games made sure to support it. When it's active, the game uses your device's camera to track your movements. If you wink, your avatar winks. If you open your mouth in shock because you just pulled a Titanic pet (lucky you), your avatar does the same.
The problem is that for the pet simulator 99 face id working status to be "active," a lot of stars have to align. It's not just a toggle inside the game; it's a combination of Roblox's site-wide privacy settings and your hardware permissions.
Checking your Roblox privacy settings
The most common reason it stops working is actually nothing to do with Pet Simulator 99 itself. Usually, it's a setting in the main Roblox menu that got flipped off during an update or because of a glitch. To check this, you have to go to your account settings (the little gear icon) and head over to the Privacy tab.
Look for the section labeled "Camera Input." If that toggle isn't green, your camera won't talk to the game, and your avatar will stay frozen. I've noticed that sometimes after a major Roblox app update, these settings reset themselves for no apparent reason. It's super annoying, but flipping it off and back on again often clears out whatever digital cobwebs were blocking the connection.
Also, keep in mind that you need to have a "Dynamic Head" equipped. If you're using one of the old-school classic blocky heads from 2012, no amount of settings-tweaking is going to make it move. You've got to use one of the newer, slightly more realistic (and sometimes creepy) heads that support animations.
Why your device might be blocking the camera
If your Roblox settings look fine but you're still not seeing the pet simulator 99 face id working as it should, the issue might be your actual phone, tablet, or PC. If you're on an iPhone or an Android, your OS has its own layer of security. You might have accidentally tapped "Don't Allow" when Roblox first asked for camera permissions.
Go into your phone's main settings, find the Roblox app, and make sure the camera permission is actually toggled on. On a PC, it's a bit different. You might have a physical privacy shutter on your webcam (I've definitely spent ten minutes wondering why my camera was "broken" only to realize I'd slid the plastic cover shut). Or, you might have another app like Zoom or Discord using the camera in the background. Windows doesn't always like sharing the camera between two apps at the same time.
In-game toggles in Pet Simulator 99
Once you're sure your hardware and Roblox account are ready to go, hop into the game. Look for the little video camera icon that usually floats above your head or appears in the top menu bar. If that icon has a red slash through it, click it! That's the manual trigger to start the face tracking within the server.
Sometimes, Pet Simulator 99 gets so crowded—especially in the Trading Plaza where there are dozens of players, pets, and hoverboards everywhere—that the game might throttle certain features to keep your frame rate from dropping into the single digits. If you're experiencing massive lag, the face ID might be one of the first things to "break" or stop responding accurately.
Is it actually worth the trouble?
You might be asking yourself if getting the pet simulator 99 face id working is even worth the five minutes of troubleshooting. Honestly? It depends on how you play. If you're a hardcore grinder who just leaves the game running on auto-clicker while you go do homework, then no, you don't need it.
But if you're big into the social side of the game, it adds a lot. There's something hilarious about standing around a trading booth and actually seeing the person you're negotiating with look frustrated or excited. It makes the world feel a little less like a collection of scripts and more like a real hangout spot. Plus, if you're a content creator or YouTuber, having that extra layer of expression on your avatar makes your footage way more engaging.
Common bugs and "The Grey Icon"
A lot of players report seeing a greyed-out camera icon. This usually means that while Roblox knows you have a camera, it can't actually communicate with it. I've found that the fastest fix for this is the "classic" solution: leave the game, close the Roblox app entirely (don't just minimize it), and restart.
If you're on PC, sometimes switching from the Roblox Microsoft Store app to the direct browser download (or vice versa) fixes the pet simulator 99 face id working issue. The two versions of the app handle hardware permissions slightly differently, and one is often more stable than the other depending on which Windows update you're currently stuck on.
Privacy and safety concerns
I should probably mention that some people get a bit nervous about turning on their camera for a game. It's a valid concern. However, Roblox has been pretty clear that they don't actually record or store the video feed. The software just looks at the "landmarks" on your face—like where your eyes and mouth are—and turns that into data points for the avatar. The actual video stays on your device and isn't sent to Big Games or Roblox servers. Still, if it makes you uncomfortable, there's no shame in leaving it off. You won't miss out on any actual gameplay mechanics or pets just because your face isn't being tracked.
Wrapping it up
At the end of the day, getting your pet simulator 99 face id working usually comes down to one of three things: a buried setting in your Roblox account, a permission issue on your phone or PC, or just the game having a bit of a moment.
If you've gone through the privacy settings, made sure your camera isn't being used by another app, and ensured you're wearing a compatible dynamic head, you should be good to go. It might take a quick restart of the game to get it to kick in, but once it does, it's a pretty fun way to experience the world of PS99. Just try not to get too distracted making funny faces in the mirror—those coins aren't going to collect themselves!
If it's still being stubborn, give it a day. Big Games is constantly pushing out small patches, and sometimes these minor features break during a big update and get fixed 24 hours later without anyone even mentioning it in the patch notes. Happy hatching!
