Galaxy S23 Phone Lineup: All the New Camera Features, Explained

Samsung’s Galaxy S23 line puts a lot of focus on its new cameras. Let’s explain what they do.

This story is part of Samsung Event, CNET’s collection of news, tips and advice around Samsung’s most popular products.

Samsung’s 2023 flagship lineup includes the Galaxy S23, Galaxy S23 Plus and Galaxy S23 Ultra, and their camera upgrades took up much of the conversation when the phones were unveiled at Samsung Unpacked last week. There are improvements across the line to the front-facing camera. The main camera on the $1,200 Ultra phone got an upgraded 200-megapixel sensor compared with the 108-megapixel one on last year’s Galaxy S22 Ultra.

But what do these camera improvements mean for you? While we’re still in the process of reviewing the Galaxy S23 series and testing their photography prowess, we can go over all the cameras and standout photo and video features each phone has.

Every Galaxy S23 phone gets a new front-facing camera

Whether you are eyeing the $800 Galaxy S22, $1,000 Galaxy S22 Plus or $1,200 Galaxy S22 Ultra, all three phones come with a 12-megapixel selfie camera that you can use for taking selfies, recording video of yourself and video calls.

The 12-megapixel camera seems like an improvement on paper for the S23 and S23 Plus — their predecessors each sported a 10-megapixel selfie camera. As far as the Ultra is concerned, the new front camera may at first look like a downgrade, because the S22 has a 40-megapixel selfie camera. But fewer megapixels isn’t necessarily a bad thing. Samsung focused on making the new selfie camera better at separating subjects from their background more clearly.

My colleague Lisa Eadicicco found in tests for her S23 Ultra review that photos taken on the new front-facing camera are equivalent to last year’s device. However, she observed that selfie photos from the Galaxy S23 Ultra occasionally looked unnatural, exaggerating hair color, compared with photos taken with the selfie cameras on the Pixel 7 Pro and iPhone 14 Pro. She also said that the S23 Ultra’s selfie camera takes better night portraits over last year’s S22 Ultra.

The new camera also supports Super HDR, which enhances color, contrast and brightness for video recorded at 4K 60fps.

Speaking of video, all of the rear cameras across the S23 lineup can record video at 8K 30fps, up from 8K 24fps on last year’s Galaxy S22 lineup. In terms of frame rates, 30fps is widely supported in apps like YouTube, Instagram and TikTok. The 8K 30fps setting isn’t really aimed at everyday use. But 8K might come in handy if you intend on playing your videos on a larger screen that is compatible with 8K or if you’re recording footage for a film as Samsung frequently suggested during its announcement. It’s also worth noting that 8K videos typically take up more space than ones recorded in 4K or HD.

Samsung also increased the field of view on the Galaxy S23 Ultra’s camera when recording in 8K, which is great considering the crop was very severe on previous Galaxy S phones that support 8K. The S21 and S22 series made footage recorded in 8K on the main wide-angle camera look like it was taken on a telephoto lens.

Galaxy S23 and Galaxy S23 Plus’ three rear cameras

The triple rear-facing cameras on the Galaxy S23 and S23 Plus are pretty much the same as their predecessors, hardware-wise, but Samsung says it’s made behind-the-scenes improvements to elements like dynamic range and glare reduction. We haven’t tested the Galaxy S23 and S23 Plus yet, but these changes were certainly noticeable on the Galaxy S23 Ultra. Otherwise, Samsung removed the camera bump, giving the S23 and S23 Plus’ cameras a similar look as those found on the S23 Ultra.

So, what does each camera do?

Let’s start off with the main camera, which has a wide-angle lens and is positioned in the middle of the other two cameras. This will be your daily driver. The main camera gives you the option to shoot in 50-megapixels, however, full resolution images need to be taken under ideal lighting conditions to capture the best quality. You may have 50 million pixels to work with, but unlike new mirrorless cameras or DSLRs of yesteryear, phone sensors and their pixels are incredibly small, and don’t absorb as much light. This leads to more image noise and the need to use more noise reduction processing, which can make details look soft and your photo look bad.

Instead, Samsung’s camera app defaults to 12-megapixel photos, which combines groups of individual pixels to act as a single larger pixel. The process is called pixel binning and results in less image noise and higher-quality photos under medium- and low-light conditions (think inside a dark restaurant).

Next, you’ve got the 12-megapixel ultra wide camera at the top of the camera array, identical to the one on its predecessor. If you want to capture more of your surroundings, pinch in on your screen to switch to this camera and its 120-degree field of view. The ultra wide is ideal for capturing landscapes and its exaggerated look makes for dramatic looking videos. It’s a fun camera to use when you shoot in slow-mo.

Finally, you have the 10-megapixel telephoto camera, at the bottom of the array, with its 3x optical zoom lens. Telephoto cameras can better capture far-away objects, subjects and backgrounds. Zooming in can help remove distracting elements from your frame. It’s also the camera you’ll use for portrait mode shots.

And of course, you can use Single Shot mode to take photos from all three rear cameras simultaneously.

Galaxy S23 Ultra’s four rear cameras, include a 200-megapixel main camera

Samsung saved its biggest camera upgrades for its premium flagship Galaxy S23 Ultra. Unlike the other two S23 series phones, the Ultra features a quadruple rear camera system, annotated in the image below.

The S23 Ultra’s pièce de résistance is a new main camera that has a massive 200-megapixel sensor — nearly double the resolution offered by the Galaxy S22 Ultra. As mentioned in the previous section, you probably won’t need to shoot at the highest resolution, unless you plan on making large prints of photos. Like the S23 and S23 Plus, the Ultra’s main camera takes 12-megapixel photos by default using pixel binning. In the case of the Ultra, it just has more pixels that it can group together which results in better looking images that are brighter and have less image noise, even under low light.

The new sensor also has Super Quad Pixel, an improved autofocus system that uses 2×2 pixel groups to help the camera’s focus lock onto details like horizons or tree trunks even when it’s dim. The S23 Ultra also supports the Expert Raw app, which allows you to capture photos using Samsung’s computational algorithms and save your snap as a raw file to retains more image data and greater dynamic range. Raw files are typically larger than JPEG files but are more ideal for photo editing since they contain more image information and settings. Samsung’s Expert Raw app supports all of the S23 Ultra’s cameras, and when you install the app, its controls are added to the native camera app.

Along with the main camera, there’s also a 12-megapixel ultra wide camera, with a 120-degree field of view, and two telephoto cameras, instead of the one found on the S23 and S23 Plus. The first telephoto lens has a 3x optical zoom, while the second one has a 10x optical zoom. The second telephoto camera also has a 100x digital zoom, but the more you zoom in, the more noisy images look. If the 10x telephoto is anything like previous Galaxy Ultra phones, its digital zoom should take decent photos up to 25x to 30x magnification, which is well beyond what the Pixel 7 Pro or iPhone 14 Pro can manage.

Before Apple’s Expected iOS 19 Reveal, Here’s What to Know About iOS 18.5

Here are all the new features you should know about in the latest iPhone update.

Apple is holding its Worldwide Developers Conference on June 9, where we will likely get a glimpse of the upcoming iOS 19. Before that announcement, Apple released iOS 18.5 on May 12, more than a month after the company released iOS 18.4. While iOS 18.4 brought more emoji to all iPhones, this latest update adds just a few small changes and a new Pride wallpaper to your iPhone. The update also includes some bug fixes and security patches everyone should download to help keep their device secure.

You can download iOS 18.5 by going to Settings > General > Software Update, then tapping Update Now and following the prompts on your screen.

Here’s what iOS 18.5 brings to your iPhone. Just a reminder, only people with an iPhone 15 Pro, Pro Max or the iPhone 16 lineup can access Apple Intelligence for now. If you have any other iPhone, you won’t have access to those features.

New Pride wallpaper

Apple releases a new Pride wallpaper ahead of Pride Month every year, and this year is no different. iOS 18.5 includes the latest iteration of the wallpaper, «Pride Harmony,» which features bold stripes that shift and change position as you move.

iOS 18.5 tweaks Mail options

Apple introduced a few Mail app updates in iOS 18.5. One of those updates makes it easier to adjust the app’s settings by showing or hiding contact photos in Mail. Contact photos are the images to the left of emails that help identify senders.

Mail will show Contact Posters by default, but you can turn them off from within the app with iOS 18.5. To do so, open Mail, tap the three dots (…) in the top-right corner of your screen, and then tap Show Contact Photos. Now, all your emails will just show the subject line and a preview of the message, similar to how Mail looked before iOS 18.

This option is in iOS 18.4, but it’s buried in Settings and not easy to locate.

Another update concerns Categories. If the mode is enabled, you can see a small tab on the right side of your screen near the other categories. Swipe the categories bar near the top of Mail to the left, and this small tab will expand to reveal the category All Mail. When you swipe left to view All Mail, it will automatically be selected, and you’ll need to tap one of the other Categories to unselect All Mail.

This category isn’t new; you could find it in iOS 18.4. But, there was no small tab on the right side of your screen to signal it was present off-screen. Therefore, All Mail flew under the radar — I didn’t even know the option was there until beta versions of iOS 18.5.

This category appears to be a way to simultaneously enable Categories and List View — the pre-Categories view of Mail. When you use All Mail, you’re viewing your messages without any categorization, like in List View.

Satellite features for all iPhone 13 models

Apple’s iOS 18.5 also brings certain satellite features, like messaging, to the iPhone 13 lineup. That means if you go off the grid, you could still text people to let them know where you are. However, these features on iPhone 13 models are carrier dependent, and currently only T-Mobile offers them in the US via Starlink.

T-Mobile Starlink is in beta, and the beta is free and open to anyone until July, including people on other carrier plans. After July, it will be part of the T-Mobile Experience Beyond and Go5G Next plans. People with other carriers, like Verizon and AT&T, will then be able to access the system for $10 a month.

Back Tap banner

The iOS 18.5 update also introduces the option to display a banner using the Back Tap function. Back Tap turns the Apple logo on the back of your iPhone into a usable button that can open your camera, take a screenshot and more when you double- or triple-tap it. And with iOS 18.5, you can make your iPhone display a banner whenever you use Back Tap.

To enable the banner, go to Settings > Accessibility > Touch > Back Tap and tap the toggle next to Show Banner. If you enable the banner and use Back Tap, the banner will appear across the top of your screen and read, «Back Tap Double/Triple Tap detected.»

iOS 18.5 release notes

Here are the full release notes for iOS 18.5.

This update also includes the following enhancements and bug fixes:

A new Pride Harmony wallpaper.
Parents now receive a notification when the Screen Time passcode is used on a child’s device.
Buy with iPhone is available when purchasing content within the Apple TV app on a third-party device.
Fixes an issue where the Apple Vision Pro app may display a black screen.
Support for carrier-provided satellite features is available on iPhone 13 (all models). For more information, visit:

Some features may not be available for all regions or on all Apple devices. For information on the security content of Apple software updates, please visit:

These 10 Hacks Could Be the End of Your Terrible Signal Forever

Say goodbye to weak bars with these reception-boosting hacks.

There’s nothing worse than being in the middle of a road trip and realizing your cell signal has dropped out. No GPS, no music and no way to call for help if something goes wrong. A weak signal can cause all kinds of problems, but the good news is that there are a few quick fixes that might get you back online fast.

Whether you’re using an iPhone or Android, these simple hacks can help boost your reception and keep you connected when you need it most.

Whether you’re doing some routine phone maintenance or you’re stuck in an emergency, there are multiple ways to improve your reception on an iPhone or Android phone, no matter what type of phone plan you’re on. It might even come down to something as simple as toggling Airplane mode.

To go from dropped calls to full bars, here’s what you need to know.

Note: Although software across different iPhone models is relatively the same, Samsung Galaxy, Google Pixel and other Android phones may have different software versions, so certain settings and where they are located might differ depending on device.

For more, check out how you can use Google Maps when you’re offline and how you can maybe fix your internet when it’s down.

To improve your cellphone service, try these steps first

The settings on your phone can help you get better cell service, but there are other tricks for improving your reception without even touching your phone’s software.

Move yourself so that there are no obstructions between your phone and any cell towers outside. That might involve stepping away from metal objects or concrete walls, which both kill reception. Instead, get to a window or go outside if possible.
Remove your phone case. It doesn’t hurt to remove whatever case you have on your phone, especially if it’s thick, so that the phone’s antenna isn’t blocked by anything and can get a better signal.
Make sure your phone is charged. Searching for and connecting to a stronger signal drains power, so if your phone battery is already low on charge, you may have a difficult time getting good service.

Always start by turning Airplane mode on and off

Turning your phone’s connection off and then back on is the quickest and easiest way to try and fix your signal woes. If you’re moving around from one location to another, toggling Airplane mode restarts the Wi-Fi, Bluetooth and cellular network modems, which forces them to find the best signal in the area.

Android: Swipe down from the top of your screen — to access the Quick Settings panel — and then tap the Airplane mode icon. Wait for your phone to completely disconnect from its Wi-Fi and cellular connections. It doesn’t happen instantly, so give it a good 15 seconds before you tap on the Airplane mode icon again.

iPhone: On the iPhone, you can access Airplane mode from the Control Center, but that varies depending on which iPhone model you have. On the iPhone X and later, swipe down from the top-right corner to access the Control Center. On older iPhone models, swipe up from the bottom of the screen. Then tap the Airplane mode icon, which will turn orange when it’s enabled. Again, wait up to 15 seconds before turning it off.

If Airplane mode doesn’t work, restart your phone

Our phones are miniature computers, and just like computers, sometimes you can fix issues like network connection by simply restarting them.

Android: Hold down the power button, or the power button and the volume down key (depending on your Android phone), until the on-screen menu shows up, and then tap Restart. If your phone doesn’t offer a restart option, you can simply tap Power Off to shut down your device, and then boot it back up with the power button.

iPhone: On the iPhone X and older models, hold down the sleep/wake button and either one of the volume buttons and then swipe right on the power slider to turn off the device. Wait until it fully turns off, then press down on the sleep/wake button to turn it back on.

Alternatively, you can do a force reset on your iPhone: Press the volume up button, followed by the volume down button and then press and hold the side button. Keep holding it in, after your phone’s screen goes black and until you see the Apple logo appear again.

If your iPhone has a home button, hold down the sleep/wake button until the power slider is displayed and then drag the slider to the right. Once the device is turned off, press and hold the sleep/wake button until you see the Apple logo.

Older phone? Take your SIM card out

Another troubleshooting step that might help is to remove your SIM card, if your phone has one, and then place it back in with the phone turned on. If the SIM card is dirty, clean it. If it has any physical defects, you may need to replace it.

You’ll need a SIM card tool — usually included in your phone’s box — or an unfolded paper clip or sewing needle to get the SIM tray out of your phone.

All phones: Remove the SIM card, check to see if it’s damaged and positioned in the SIM tray correctly, then put it back in your phone.

eSIM: For phones with an eSIM — that is, an embedded electronic SIM in your phone — there’s nothing for you to remove. The best you can do is restart your phone.

Check your carrier settings (and update your software)

Mobile carriers frequently send out carrier settings updates to help improve connectivity for calls, data and messages on their network. Although this feature is available on all iPhone models, it’s not universal on Android, so you might not find carrier settings if you don’t have a supported phone.

iPhone: Carrier updates should just appear, and you can update from the pop-up message that appears. To force your iPhone to check for a carrier settings update, go to Settings > General > About on your phone. If an update is available, you’ll be prompted to install it.

Android: As mentioned before, not all Android phones have carrier settings, so you’ll have to open the Settings app and type in «carrier settings» to find any possible updates. On supported Pixels, go to Settings > Network & internet > Internet, tap the gear next to your carrier name and then tap Carrier settings versions.

Reset your phone’s network settings

Sometimes all you need is a clean slate to fix an annoying connectivity issue. Refreshing your phone’s network settings is one way to do that. But be forewarned, resetting your network settings will also reset any saved Wi-Fi passwords, VPN connections and custom APN settings for those on carriers that require additional setup.

Android: In the Settings app, search for «reset» or more specifically «reset network settings» and tap on the setting. On the Pixel, the setting is called Reset Wi-Fi, mobile & Bluetooth. After you reset your network settings, remember to reconnect your phone to your home and work Wi-Fi networks.

iPhone: Go to Settings > Transfer or Reset iPhone > Reset > Reset Network settings. The next page will warn you that resetting your network settings will reset your settings for Wi-Fi, mobile data and Bluetooth. Tap Reset Network Settings and your phone will restart.

Contact your phone carrier

Sometimes unexpected signal issues can be traced back to problems with your wireless carrier. A cell tower could be down, or the tower’s fiber optic cable could have been cut, causing an outage.

For consistent problems connecting to or staying connected to a cellular or data network, it’s possible your carrier’s coverage doesn’t extend well into your neighborhood.

Other times, a newfound signal issue can be due to a defect with your phone or a SIM card that’s gone bad. Contacting your carrier to begin troubleshooting after you’ve tried these fixes is the next best step to resolving your spotty signal.

If all else fails, try a signal booster to improve cell reception

If after going through all of our troubleshooting steps, including talking to your carrier to go over your options, you’re still struggling to keep a good signal — try a booster. A signal booster receives the same cellular signal your carrier uses, then amplifies it just enough to provide coverage in a room or your entire house.

The big downside here is the cost. Wilson has three different boosters designed for home use, ranging in price from $349 for single room coverage to $999 to cover your entire home. To be clear, we haven’t specifically tested these models. Wilson offers a 30-day money-back guarantee and a two-year warranty should you have any trouble with its products.
