Is the Galaxy S25 Ultra zoom the best? I tested it and it's close
The year was 2020, the month was February and Samsung had just kicked off yet another smartphone generation. The Galaxy S20 Ultra brought a lot of new features to the market, but crucially, Samsung's marketing also made long zoom features and Ultra branding extremely desirable.
One of the key reasons to buy the Galaxy S20 Ultra — and subsequent Ultra phones from Samsung — was the camera. It featured a 108MP main sensor, a 12MP ultrawide camera, and a 48MP periscope telephoto camera that offered 4x optical zoom and 10x hybrid zoom. The latter also enabled the new 100X Space Zoom feature, which Samsung still promotes on its Ultra phones today.
Fast forward five years, and while the lineup has changed, the premise is still the same. The Galaxy S25 Ultra offers a 200MP main sensor, a 50MP ultrawide sensor, and two periscope lenses, one at 10MP with 3x optical zoom and the other at 50MP with 5x optical zoom. Yet, Samsung faces a problem: its Ultra phones face huge competition from the competition and it may no longer have the best zoom camera in the US.
To find out if it's still the best, I tested it against the main competition and it's very close: here's what happened and which phone wins.
For a few years, Samsung faced no real competition in the US or most Western countries. As a result, the company was mostly able to refine its lineup at its own pace, without the added pressure of intense competition.
The Galaxy S20 Ultra introduced the Zoom race, whilst the Galaxy S21 Ultra saw Samsung adopt the quad-camera approach that it still uses today. It featured the same 108MP main camera, but introduced a 10MP telephoto lens with 3x optical zoom — still in use today — and a secondary 10MP periscope lens with 10x optical zoom.
The Galaxy S22 Ultra featured the same camera as the S21 Ultra, but with the Galaxy S23 Ultra, Samsung introduced a new 200MP main camera. This is the same one that's found on the Galaxy S25 Ultra. Last year's Galaxy S24 Ultra then saw Samsung tweak its approach to the zoom camera, by dropping the 10MP periscope lens with 10x optical zoom in favor of a 50MP periscope lens offering 5x optical zoom.
The Galaxy S25 Ultra keeps the same camera array as the Galaxy S24 Ultra but introduces a new 50MP ultrawide lens. However, the 3x and 5x telephoto lenses have proven to be fairly capable at low zoom lengths, but struggle to match another phone at the same 100x zoom length. The kicker for Samsung is that the other phone only has a single telephoto lens that only offers a 3x optical zoom.
As Samsung has proven there is global demand for phones with strong zoom capabilities, the competition has taken notice. Apple, Google, and OnePlus have all considered Samsung's success and sought out different approaches to the camera to achieve similar, or better, results than Samsung's best phone.
Here's how the Galaxy S25 Ultra camera compares to the key flagship from each phone:

Samsung remains the only company in the US to adopt two telephoto lenses, with the 3x telephoto matching the one on the OnePlus 13, while the 5x matches the same zoom capabilities found on the iPhone 16 Pro and Pixel 9 Pro.
However, as we'll see, the adage continues to ring true: it's not just the hardware that matters, but how each camera and ISP uses the hardware. Further complicating this is the use of AI in post-processing and how each company uses it to further enhance the final photo.
On paper, the Galaxy S25 Ultra should be the most capable zoom camera in the US, but as the headline suggests, this is no longer the case. I've been traveling with Samsung's latest flagship for several weeks and have tested it against the key competition in the US during both day and night.
For each zoom length, I've picked two sets of daytime photos to evaluate the zoom. One of these focuses on the ability to zoom into text and finer details, while the other points to its ability to zoom into landscapes and other subjects. Each phone has plenty of zoom lengths, but for this comparison, I've focused on the key ones: 1x, 3x/5x depending on which each phone has, 10x and 25x or 30x.
What about the competition? First, let's consider the Pixel 9 Pro. Google's flagship offers a 5x zoom and a maximum of 30x zoom, so let's look at each comparison. Here's the first sample set.
Next, let's look at the performance in the second scene.
The Pixel 9 Pro is fairly impressive in these two scenes, and I prefer it for the first two images in the first scene. However, once you get into the details, the Galaxy S25 Ultra beats it thanks to extra detail in the balcony railings, the cruise ship deck, and the sign on the cruise ship. It's quite close, but the Galaxy S25 Ultra still wins this comparison.
Next, let's look at the iPhone 16 Pro. Samsung's flagship is billed as a competitor to the iPhone 16 Pro Max, which features the same camera as its smaller sibling. The iPhone 16 Pro also features the same 5x found on the iPhone 16 Pro Max, which was previously exclusive just to the Max lineup.
Here's how the two compare.
Next, let's look at the performance in the second scene.
The iPhone 16 Pro is limited to just 25x maximum zoom and these images show why Apple limits the maximum zoom on its phones. The Galaxy S25 Ultra wins, but like the Pixel 9 Pro, I think both phones are quite similar at the lowest zoom lengths.
If we were to stop this comparison right now, Samsung would probably still rein supreme, but there's one device remaining. On paper, the OnePlus 13 shouldn't be able to compete with the Galaxy S25 Ultra given its telephoto lens only has a 3x optical zoom and it lacks the 6x found on its non-US sibling, the Find X8 Pro. It does still feature a 6x option that's billed as a hybrid between digital and optical zoom, so I've included this in the test as a comparison against the 5x on the Galaxy S25 Ultra.
Next, let's look at the performance in the second scene.
Both phones are evenly matched throughout these comparisons, and it's quite surprising that the OnePlus 13 can match the Galaxy S25 Ultra despite the lack of a fourth camera, and the smaller 3x optical zoom. At 30x zoom, the Galaxy S25 Ultra is just slightly better, but overall, they feel equally matched.
Unlike the iPhone 16 Pro and Pixel 9 Pro, the OnePlus 13 also goes further than 30x and this is where I've been blown away. From the same sets above, here are the same shots at 100x on the Galaxy S25 Ultra, and the maximum 120x on the OnePlus 13.
As you can see, the OnePlus 13 picks up where Google left off and proves that you don't necessarily need the best hardware to capture the best photos. Despite inferior zoom capabilities — on paper, at least — it has the best zoom of any of these phones I've tested. In particular, the AI does an excellent job of filling in missing details and throughout all my testing, it's consistently proven to be better than the Galaxy S25 Ultra at the higher zoom lengths.
The iPhone is well-known for its video recording capabilities, but one of the new touted features for the Galaxy S25 Ultra is super smooth video zoom. In particular, this is a smooth transition between the different lenses when recording video, versus a choppy transition between lenses as has been common for many years.
Does the Galaxy S25 Ultra deliver on both of these fronts? How does it compare to the competition? Let's take a quick look, starting with the Galaxy S25 Ultra:
What about the iPhone 16 Pro?
Now, here's the Pixel 9 Pro:
Lastly, here's the OnePlus 13:
The smooth transition between lenses and improved video recording on the Galaxy S25 Ultra has improved Samsung's overall performance in video recording. For zoom, the Galaxy S25 Ultra delivers strong performance — at least in the daylight — that's on par with the iPhone 16 Pro, although Samsung has better overall quality given the stronger zoom performance. The Pixel 9 Pro comes close, and the OnePlus 13 is shakier, with less overall quality.
The appeal of the Galaxy S25 Ultra and the iPhone 16 Pro is that both remain widely available in most markets. In contrast, Pixel 9 Pro availability is more limited, and the OnePlus 13 is even more limited. Yet, if you live in the US, these four devices are your top choice when looking for the best smartphone camera, and there's no contest for me. I've been blown away by the performance of the OnePlus 13 camera, so much so that it's replaced the Galaxy S25 Ultra as my camera of choice.
Of course, as we covered in our Galaxy S25 Ultra review, Samsung's latest flagship has further benefits such as the S-Pen, a better portrait mode than any other phone, and outstanding performance and battery life. All of these are worthwhile benefits — some of which are also matched by the OnePlus 13 — but if you want the best zoom camera and you live in the US, there's no contest: the OnePlus 13 has taken Samsung's zoom crown in the US and is a strong contender for best phone of 2025.

WhatsApp Issues Urgent iPhone Countdown: Chats Stop In 24 Hours On These Phones
WhatsApp is ending support for a series of Apple and Android devices, beginning on Sunday, June 1. It had been thought the change would come early in June, but the respite is over. Here's the list of iPhones affected and what it means. Apple iPhones with older software are about to lose access to WhatsApp. If you have an iPhone 5s, iPhone 6 or iPhone 6 Plus, then first of all congratulations for holding out against the pressure to upgrade. But, secondly, commiserations, because your phone won't work with WhatsApp any more. That's because you need to have an iPhone that runs iOS 15.1 and later, and those phones can't handle software newer than iOS 14. If you want to continue to use WhatsApp, you'll need a newer iPhone (or iPad, now it's finally arrived on Apple's tablets). Android users are fine, providing your phone can run Android OS 5.0 and newer. The new software requirements have been announced by WhatsApp and the explanation is that 'Devices and software change often, so we regularly review what operating systems we support and make updates. Every year we look at which devices and software are the oldest and have the fewest users. These devices also might not have the latest security updates, or might lack the functionality required to run WhatsApp,' it says. To be fair to WhatsApp, support is only vanishing for iPhones that first went on sale more than 10 years ago, and which weren't sold by Apple for the last six years. And note the phrase 'Every year,' which tells us that if you have any iPhone newer than that, you're safe until next year at least. As noted by 9to5Mac, it had been reported that other iPhones would also be struck off, namely iPhone 16s, iPhone 6s Plus and iPhone SE 1st generation. However, this doesn't seem to be the case, providing, of course, you have updated the phone's software to later than iOS 15.1. This shouldn't be a problem as those phones are compatible with every version of iOS 15, including the recent iOS 15.8.1, a security update released a few weeks ago on March 31, 2025.

Massive data breach exposes 184 million passwords and logins
Data breaches are no longer rare events but a persistent problem. We've been seeing regular incidents at public-facing companies across various sectors, including healthcare, retail and finance. While bad actors are certainly to blame, these corporations aren't entirely without fault. They often make it easy for hackers to access user data by failing to protect it properly. A recent example came to light when a cybersecurity researcher discovered an open database containing over 184 million account credentials. Cybersecurity researcher Jeremiah Fowler has revealed the existence of an open database that contains 184,162,718 million account credentials. These include email addresses, passwords, usernames and URLs for platforms such as Google, Microsoft, Apple, Facebook and Snapchat. The information also covers banking services, medical platforms and government accounts. Most shockingly, the entire dataset was left completely unsecured. There was no encryption, no authentication required and no form of access control. It was simply a plain text file sitting online for anyone to find. Fowler located the database during routine scanning of publicly exposed assets. What he found was staggering. The file included hundreds of millions of unique records containing user credentials linked to the world's largest technology and communication platforms. There were also account details for financial services and official portals used by state institutions. The file was not protected in any way. Anyone who discovered the link could open it in a browser and instantly view sensitive personal data. No software exploit was needed. No password was asked for. It was as open as a public document. Fowler believes the data was harvested using an infostealer. These lightweight tools are favored by cybercriminals for their ability to silently extract login credentials and other private information from compromised devices. Once stolen, the data is often sold on dark web forums or used in targeted attacks. After reporting the breach, the hosting provider quickly removed access to the file. However, the owner of the database remains unknown. The provider did not disclose who uploaded it or whether the database was part of a legitimate archive that was accidentally published. Fowler could not determine whether this was the result of negligence or an operation with malicious intent. To verify the data, Fowler contacted some individuals listed in the records. Several confirmed that the information was accurate. This confirmation turns what might seem like abstract statistics into something very real. These were not outdated or irrelevant details. These were live credentials that could allow anyone to hijack personal accounts in seconds. 1. Change your password on every platform: If your login credentials have been exposed, it's not enough to change the password on just one account. Cybercriminals often try the same combinations across multiple platforms, hoping to gain access through reused credentials. Start by updating your most critical accounts, email, banking, cloud storage and social media, then move on to others. Use a new, unique password for each platform and avoid variations of old passwords, as they can still be predictable. Consider using a password manager to generate and store complex passwords. Our top-rated password manager delivers powerful protection to help keep your accounts secure. It features real-time data breach monitoring to alert you if your login details have been exposed, plus a built-in data breach scanner that checks your saved emails, passwords and credit card information against known leak databases. A password health checker also highlights weak, reused or compromised passwords so you can strengthen your online defenses with just a few clicks. Get more details about my best expert-reviewed Password Managers of 2025 here. 2. Enable two-factor authentication: Two-factor authentication, or 2FA, is a critical security feature that drastically reduces the risk of unauthorized access. Even if someone has your password, they won't be able to log in without the second verification step, usually a one-time code sent to your phone or an authenticator app. Enable 2FA on all services that support it, especially your email, financial accounts and any service that stores sensitive personal data. 3. Watch for unusual account activity: After a breach, it's common for compromised accounts to be used for spam, scams, or identity theft. Pay close attention to signs such as login attempts from unfamiliar locations, password reset requests you didn't initiate or unexpected messages sent from your accounts. Most platforms allow you to review login history and connected devices. If you see something off, take action immediately by changing your password and revoking suspicious sessions. 4. Invest in personal data removal services: You should also consider a data removal service. Given the scale and frequency of breaches like the one described above, relying on personal caution alone is no longer enough. Automated data removal services can provide an essential extra layer of defense by continuously scanning for and helping eliminate your exposed information from data broker sites and other online sources. While no service promises to remove all your data from the internet, having a removal service is great if you want to constantly monitor and automate the process of removing your information from hundreds of sites continuously over a longer period of time. Check out my top picks for data removal services here. Get a free scan to find out if your personal information is already out on the web. 5. Avoid clicking on suspicious links and use strong antivirus software: One of the most common post-breach threats is phishing. Cybercriminals often use information from leaked databases to craft convincing emails that urge you to verify your account or reset your password. Never click on links or download attachments from unknown or suspicious sources. Instead, visit websites by typing the URL directly into your browser. The best way to safeguard yourself from malicious links is to have strong antivirus software installed on all your devices. This protection can also alert you to phishing emails and ransomware scams, keeping your personal information and digital assets safe. Get my picks for the best 2025 antivirus protection winners for your Windows, Mac, Android and iOS devices. 6. Keep your software and devices up to date: Many cyberattacks exploit known vulnerabilities in outdated software. Operating systems, browsers, antivirus programs and even apps need to be updated regularly to patch security flaws. Turn on automatic updates wherever possible so you're protected as soon as fixes are released. Staying current with your software is one of the easiest and most effective ways to block malware, ransomware and spyware from infiltrating your system. Security is not only the responsibility of companies and hosting providers. Users need to adopt better practices, including unique passwords, multifactor authentication and regular reviews of their digital footprint. The careless exposure of over 184 million credentials is not just a mistake. It is an example of how fragile our systems remain when even basic protection is absent. In an era where artificial intelligence, quantum computing, and global connectivity are reshaping technology, it is unacceptable that plain text files containing financial and governmental credentials are still left sitting online.
