Google Lens is built into most phones and cameras — you just need to know where to find the button
Google Lens is a tool that identifies objects, text, and places from photos you take or upload. On Android phones, it usually lives in the Google app or camera app and is ready to use once you open it. On iPhones, you access it through Google Photos or the Google app. The button or icon looks like a small square with a dot in the center, or sometimes a lens symbol. Once you tap it, point your phone's camera at something — a plant, a book cover, a street sign, a piece of furniture — and Google Lens will tell you what it is, where to buy it, or what information is available about it.
You do not need to take a photo first. You can open Lens and point your camera in real time, and it will start identifying things as you move the phone around. This is useful when you are standing in a store or a room and want to know the name or price of something when ready.
Key Takeaways
- On Android, open the Google app or camera app and tap the Lens icon — usually a small square with a dot or a lens symbol.
- On iPhone, open Google Photos or the Google app, tap the Lens icon, and point your camera at the object you want to identify.
- You can search in real time by pointing your camera, or upload a photo you already took to search it later.
- Lens works best with clear, well-lit photos of objects, text, plants, animals, and landmarks — it is less reliable with abstract images or very small details.
- You need a Google account and an internet connection for Lens to work, because the identification happens on Google's servers, not on your phone.
Turning on Google Lens on Android phones
On most Android phones, the fastest way is to open the Google app (the one with the colorful "G" icon). Tap the camera icon at the bottom of the search bar. This opens Google Lens in real-time mode — your phone's camera is now active and Lens is watching what you point it at.
If you want to search a photo you already took, tap the image icon (usually next to the camera icon) and select the photo from your phone's gallery. Google Lens will analyze it and show you results.
Some Android phones also have Lens built into the camera app itself. Open your camera app, look for a Lens icon or a small square symbol, and tap it. The experience is the same — you can search in real time or upload an existing photo.
Turning on Google Lens on iPhones
On iPhone, open the Google Photos app (not the built-in Photos app). Tap the search icon at the bottom of the screen — it looks like a magnifying glass. You will see a camera icon. Tap it to open Lens in real-time mode.
Alternatively, open the Google app and tap the camera icon in the search bar at the top. This also opens Lens and works the same way.
If you want to search a photo you already have, open Google Photos, find the photo, and tap the search icon at the bottom. Google Lens will analyze it automatically.
What Google Lens can and cannot do well
Lens works best on clear, well-lit photos of objects (furniture, clothing, plants, animals), text (signs, menus, documents), and landmarks (buildings, monuments, famous locations). Point your camera at a chair and Lens will often tell you the style, show you similar chairs for sale, and link to reviews. Photograph a plant and it will usually identify the species. Take a picture of a street sign or a restaurant name and Lens will read the text and search for information about it.
Lens is less reliable with abstract images, very small details, handwriting, or photos taken in dim light. If you point it at a blurry photo or a drawing, it may not recognize what you are looking at. Text that is at an angle, very small, or in an unusual font sometimes does not get read correctly.
Lens cannot tell you the price of something unless that price is visible in the photo or the item is sold online. It cannot identify people by their faces. It cannot access information that is not publicly available on the internet.
Making Lens searches more accurate
Take the clearest photo you can. Hold your phone steady, make sure the object is in focus and well-lit, and fill most of the frame with the thing you want to identify. If you are photographing text, hold the phone parallel to the text so it is not at an angle.
If Lens gives you results that do not match what you are looking at, try moving closer or farther away, or tilting the phone slightly. Sometimes a different angle helps Lens see the object more clearly. You can also tap the image icon and upload a different photo of the same thing.
If you are searching for something to buy, Lens will show you links to online retailers. These results depend on what is available for sale at the time you search — the same object may show different prices or sellers on different days.
Checking that you have the right permissions and connection
Google Lens needs permission to use your phone's camera. When you first open Lens, your phone will ask whether you want to allow the Google app (or camera app) to access the camera. Tap Allow. If you denied permission before and want to turn it back on, go to your phone's Settings, find the app (Google or Camera), tap Permissions, and turn on Camera.
Lens also needs an internet connection. It works on Wi-Fi or mobile data. If you are offline, Lens will not be able to search or identify anything.
Make sure you are signed into your Google account. Open the Google app, tap your profile picture in the top right corner, and check that you are logged in. If you are not, tap Sign in and enter your email and password.
Frequently Asked Questions
Does Google Lens cost money?
No. Google Lens is free to use. You need a Google account and an internet connection, but there are no subscription fees or charges per search.
Can I search a photo without taking a new one?
Yes. On Android, open the Google app, tap the camera icon, then tap the image icon to upload a photo from your gallery. On iPhone, open Google Photos, find the photo, and tap the search icon at the bottom. Lens will analyze the photo you already have.
What happens to my photos when I use Lens?
Google analyzes the photo on its servers to identify what is in it. Google stores this data according to its privacy policy. If you are concerned about privacy, you can delete your search history in the Google app by going to Settings and tapping Manage your Google Account, then the History tab.
Why is Lens not working on my phone?
Check that you have an internet connection, that camera permission is turned on, and that you are signed into your Google account. If Lens still does not work, try closing the app completely and opening it again. If your phone is very old, Lens may not be available — it requires Android 6.0 or later, or iOS 12 or later.
Can Lens identify people's faces?
No. Lens cannot identify who a person is by their face. It can recognize that a photo contains a person, but it will not tell you their name or search for information about them.
