Samsung Galaxy Watch3 vs. Apple Watch 5


With new health features, Samsung’s latest smartwatch may be tempting: Should you buy a Galaxy Watch3 or an Apple Watch 5?

Samsung released a slew of products at its Galaxy Unpacked event, and its latest smartwatch, the Galaxy Watch3, was among them.

It’s undoubtedly a gorgeous device, with the standard Samsung rotating bezel and a round design that the company said was modeled after older precision timepieces of the analog age. The Galaxy Watch3 also packs some big improvements over last generation’s version, including a blood oxygen sensor, thinner body, and slightly larger screen.

But what about the other top-tier smartwatch on the market? The Apple Watch 5 is every bit a competitor to the Galaxy Watch3, and picking a watch between the two might be tricky if you’re tempted by the just-revealed Galaxy Watch3.

Where to buy

At Samsung’s website

At Apple’s website, Best Buy, and other retailers

Looking at the hardware itself, the differences are minimal: Both offer sizes with a mere 1mm difference, their connectivity is the same, and they weigh less than a few tenths of an ounce different from each other. 

The biggest physical differences between the two (outside of their shapes) is the Apple Watch 5’s far better screen-to-body ratio, and the Galaxy Watch3’s larger battery.

The Galaxy Watch3 has some additional health features that the Apple Watch 5 lacks, like the ability to take blood pressure and measure blood oxygen content, so if health features are something you’re looking for the Galaxy Watch3 may be a better bet. Although the blood pressure measurement isn’t available yet in the US. And the SpO2 app isn’t available yet to track blood oxygen content.

Do you have to own a Samsung/Apple device to use the Galaxy Watch3/Apple Watch 5?

Cross-compatibility between the two products is definitely skewed in Samsung’s favor. Not only is the Galaxy Watch3 compatible with a bunch of Android devices, but it can also be used with an iPhone. 

The Apple Watch 5, on the other hand, is an iPhone-only product: If you’re not all in on Apple’s ecosystem don’t even think about getting an Apple Watch.

Don’t rush to Samsung’s online site to preorder a Galaxy Watch3 yet, though: It might work with an iPhone, but there are a lot of qualifications to that statement that render it somewhat useless, especially if you’re a business professional who uses a smartwatch to get work done without needing to pull out a phone.

According to Samsung, a Galaxy Watch running on iOS:

  • Can’t be used to reply to messages or emails,
  • Doesn’t have any S Health features available,

  • Can’t use any Samsung branded features like Samsung Pay, emergency SOS functions, Nike Running, etc.,

  • Can only have music loaded to it using the PC version of Music Manager, 

  • Only has access to free Watch-specific apps

That list is filled with essential features, especially message replying and health features. If you don’t want to use an Apple Watch with your iPhone you may be better off just getting an analog watch.

What it all comes down to

Feature similarity aside, this particular debate, like many others that involve Apple and leading tech companies like Samsung or Google, come down to ecosystem. The Apple Watch 5 pairs seamlessly and works great with Apple products, and the same goes for the Galaxy Watch3 and Samsung/Android products. 

If you’re an Android user, there’s no point in getting an Apple Watch 5 unless you plan to jump ship to an iPhone, which means you’re leaving the Android ecosystem and all the apps you’ve purchased, the music you’ve bought on Google Play (still accessible on iOS, but it isn’t the default), and other Android features you’re used to and have invested your time and money in. 

If you use an iPhone, don’t be tempted to invest in a Galaxy Watch3 despite cross-platform support promises: Many of the features that make it a great smartwatch won’t be supported on you iPhone, and getting the most out of it would mean switching to Android and losing the same purchases and time investment that an Android user would lose in switching to iOS. 

Apple users: Want the Galaxy Watch3 features missing from the Apple Watch 5? Just wait.

There are a few features present in the Galaxy Watch3 that Apple Watch users may be pining for: Blood oxygen tracking and robust sleep tracking features among them. 

According to TechRepublic sister site CNET, the Apple Watch 6 is likely to be revealed in September, with those two features among the additions.

Even if those two features aren’t something that makes you want a new smartwatch, we’re very close to the likely reveal date of the Apple Watch 6, which is yet another reason not to go out and buy an Apple Watch 5, unless you want to get that model at a reduced price once the Series 6 is out.

Watch out for these subject lines in email phishing attacks


Campaigns exploiting COVID-19 remained popular last quarter, but cybercriminals also relied on tried and true subjects, says KnowBe4.

Email phishing attacks work by spoofing or referencing well-known topics that the attackers hope will arouse fear or concern or interest on the part of the recipients. These types of campaigns also try to exploit subjects that are in the news, which is why coronavirus-related phishing emails have been a common tactic since the virus surfaced earlier this year. A report published Wednesday by security trainer KnowBe4 looks at some of the most common subjects used in phishing emails during the second quarter of 2020.

To compile its “Q2 2020 Top-Clicked Phishing Report,” KnowBe4 examined tens of thousands of email subject lines from simulated phishing tests as well as “in-the-wild” email messages that employees received and reported to their IT departments as suspicious. The templates for the simulated phishing tests, which organizations use to help educate employees, were based on real phishing attacks.

Email phishing attacks with subjects related to COVID-19 remained prevalent last quarter, accounting for 56% of all the subject lines analyzed. Beyond directly mentioning the coronavirus, some of these scam emails alluded to related side effects, such as work reopenings, rescheduled meetings, stimulus payments, and new vacation policies.

“It’s no surprise that phishers and scammers are using the avalanche of new information and events involving the global coronavirus pandemic as a way to successfully phish more victims,” KnowBe4 CEO Stu Sjouwerman said in a press release. “These phishing scams are becoming more aggressive and more targeted as this pandemic continues. Everyone should remain very skeptical of any email related to COVID-19 coming into their inbox.”

However, cybercriminals also tapped into such popular subjects as social media sites like Facebook and LinkedIn, password resets, and security alerts. Among the top social media subjects, LinkedIn accounted for 42% of the analyzed emails with such subject lines as “You appeared in new searches this week,” “People are looking at your LinkedIn profile,” “Please add me to your LinkedIn Network,” and “LinkedIn Password Reset.”

Phishing attacks that exploited Facebook used such subject lines as “Your Friend Tagged a Photo of You” and “Your friend tagged you in photos on Facebook.” Campaigns spoofing Twitter tried to entice people with a subject line of “Someone has sent you a Direct Message on Twitter.”

“A login alert for Chrome on Motorola Moto X,” “New voice message at 1: 23AM,” and “55th Anniversary and Free Pizza” were other subjects touted in phishing emails.

“LinkedIn messages continue to dominate the top social media email subjects, with several variations of messages such as ‘people are looking at your profile’ or ‘add me,'” KnowBe4 said in its report. “Other alerts containing security-related warnings come unexpectedly and can cause feelings of alarm. Messages such as a friend tagged you in a photo or mentioned you can make someone feel special and entice them to click. And everyone loves free pizza!”

The top 10 general subjects seen in the simulated phishing emails analyzed last quarter include:

  1. Password Check Required Immediately
  2. Vacation Policy Update
  3. Branch/Corporate Reopening Schedule
  4. COVID-19 Awareness
  5. Coronavirus Stimulus Checks
  6. List of Rescheduled Meetings Due to COVID-19
  7. Confidential Information on COVID-19
  8. COVID-19 – Now airborne, Increased community transmission
  9. Fedex Tracking
  10. Your meeting attendees are waiting!

“Hackers are playing into employees’ desires to remain security minded,” KnowBe4 said in the report. “Unsurprisingly, half of the top subjects for this quarter were around the coronavirus pandemic. Curiosity is also piqued with security-related notifications and HR-related messages that could potentially affect their daily work.”

Looking at the subject lines found among the “in-the-wild” phishing emails last quarter, KnowBe4 identified the following as the top 10:

  1. Microsoft: Abnormal log in activity on Microsoft account
  2. Chase: Stimulus Funds
  3. HR: Company Policy Notification: COVID-19 – Test & Trace Guidelines
  4. Zoom: Restriction Notice Alert
  5. Jira: [JIRA] A task was assigned to you
  6. HR: Vacation Policy Update
  7. Ring: Karen has shared a Ring Video with you
  8. Workplace: [company_name] invited you to use Workplace
  9. IT: ATTENTION: Security Violation
  10. Earn money working from home

“Here again we see subjects related to the coronavirus and working from home,” KnowBe4 said in its report. “Cybercriminals are preying on heightened stress, distraction, urgency, curiosity, and fear in users. These types of attacks are effective because they cause a person to react before thinking logically about the legitimacy of the email.”

With phishing emails a persistent threat, Javvad Malik, security awareness advocate for KnowBe4, advises organizations to educate employees on how to identify and report them.

“With the majority of business for many organizations being conducted over email, it is not unusual for emails to be sent requesting or providing commercial information,” Malik said. “But not everything is always what it seems, and users should exercise caution when they receive any unsolicited, or unexpected emails, particularly ones which contain links or attachments. It is why it’s important for organizations to invest in security awareness training so that users can identify and report any suspected phishing emails.”
