Everything We Know About the Samsung Galaxy S9 So Far, From Rumors to Release Date

Samsung is just a few weeks away from releasing the long-awaited Galaxy S9, the latest in its long line of Android-based Apple iPhone competitors.
Companies like Samsung are notoriously tight-lipped about what their upcoming smartphones might look like, or what features they might include. So far we know for sure when Samsung’s Galaxy S9 will be officially unveiled, and that Samsung is pitching the S9’s camera as a main selling point.
But there’s an entire cottage industry built up around smartphone rumors and leaks that we can use to glean some more information about the Samsung Galaxy S9’s potential features, specs, price and more.
Here’s what we know about the Samsung Galaxy S9 so far.
Samsung Galaxy S9 Release Date and Price
Samsung will unveil the Galaxy S9 (and likely a larger Galaxy S9 Plus version) on Sunday, Feb. 25 during Mobile World Congress (MWC) in Barcelona, Spain. Samsung typically begins shipping new smartphones within a few weeks of announcing them. So it’s a safe bet you’ll start seeing the Galaxy S9 on store shelves and available online by mid-March or so.
The Galaxy S9 price isn’t clear yet. But it’s likely to be comparable to Apple’s most expensive phones — that is, in the $699-$999 range.
Samsung Galaxy S9 Specs
The U.S. version of the Samsung Galaxy S9 could use Qualcomm’s Snapdragon 845 processor, which will help it take better pictures and video, enable new artificial intelligence improvements, and result in overall better and more efficient performance. The Snapdragon could help improve the battery life on Samsung’s Galaxy S9 without physically larger batteries, too.
The Samsung Galaxy S9 that will be sold in other parts of the world might use Samsung’s own Exynos processor instead of the Snapdragon, CNBC reports.
Samsung Galaxy S9 Camera
The camera will be a chief selling point for the Galaxy S9, if Samsung’s promotional teaser is any indication. The aforementioned Snapdragon 845 processor would certainly help in that regard. The Galaxy S9 could get some improvements in the camera system itself, too, with a 12-megapixel rear-facing camera featuring an f/1.5 lens, Forbes reports. A lens with that wide an aperture would certainly help with low-light photography.
It’s unclear whether Samsung will give both the standard issue Galaxy S9 and the Galaxy S9 plus a dual rear-facing camera system, or only put such a setup on the Plus model. Details about the front-facing camera system are also shaky at this point.
Samsung Galaxy S9 Features
Samsung’s Galaxy S9 is rumored to have some bonus features that might excite some Android fans out there. Samsung is reportedly working on big improvements to its eye-scanning tech, for example, making it more secure and function better than it does on previous Galaxy models. There’s also a chance the Galaxy S9 could have some kind of face-scanning unlocking feature similar to Apple’s Face ID system.
There have been rumors that the Samsung Galaxy S9 would include a fingerprint scanner built directly into the touchscreen, but recent reports say that might not be the case after all.

Also worth noting: The Galaxy S9 could feature an FM radio option, Tom’s Guide reports, allowing users to tune in to local radio broadcasts. That may seem a little retro on such a high-tech device, but it’s an option that some people have long wanted.

How to remove malware from your Windows PC

Beware the signs of a potentially malware-infested PC: slower-than-usual performance, the recent occurrence of lots of pop-ups, and other weird issues. It’s possible your system has been infected by a virus, spyware, or other nefarious entity—even if you have an antivirus program installed. Yes, out-of-the-ordinary behavior is sometimes the result of hardware issues, but it’s best to first rule out malware if your PC is acting up. Here’s a step-by-step guide for taking action.
Step 1: Enter Safe Mode
Before you do anything, you need to disconnect your PC from the internet, and don’t use it until you’re ready to clean your PC. This can help prevent the malware from spreading and/or leaking your private data.
If you think your PC may have a malware infection, boot your PC into Microsoft’s Safe Mode. In this mode, only the minimum required programs and services are loaded. If any malware is set to load automatically when Windows starts, entering in this mode may prevent it from doing so. This is important because it can make removing the nefarious files easier since they’re not actually running or active.
You may find that your PC runs noticeably faster in Safe Mode. This could be a sign that your system has a malware infection, or it could mean that you have a lot of legitimate programs that normally start up alongside Windows. If your PC is outfitted with a solid-state drive it’s probably fast either way.
Step 2: Delete temporary files
Now that you’re in Safe Mode, you’ll want to run a virus scan. But before you do that, delete your temporary files. Doing this may speed up the virus scanning, free up disk space, and even get rid of some malware. To use the Disk Cleanup utility included with Windows 10 just type Disk Cleanup in the search bar or after pressing the Start button and select the tool that appears named Disk Cleanup.
Step 3: Download malware scanners
Now you’re ready to have a malware scanner do its work—and fortunately, running a scanner is enough to remove most standard infections. If you already had an antivirus program active on your computer, you should use a different scanner for this malware check, since your current antivirus software may not have detected the malware. Remember, no antivirus program can detect 100 percent of the millions of malware types and variants.
There are two types of antivirus programs. You’re probably more familiar with real-time antivirus programs, which run in the background and constantly watch for malware. (Another option is an on-demand scanner, which searches for malware infections when you open the program manually and run a scan. You should have only one real-time antivirus program installed at a time, but you can have many on-demand scanners installed to run scans with multiple programs, thereby ensuring that if one program misses something a different one might find it.
Step 4: Fix your web browser
Malware infections can damage Windows system files and other settings. One common malware trait is to modify your web browser’s homepage to reinfect the PC, display advertisements, prevent browsing, and generally annoy you.
Before launching your web browser, check your homepage and connection settings. For Internet Explorer right-click the Windows 10 Start button and select Control Panel, then Internet Options. Find the Home Page settings in the General tab, and verify that it’s not some site you know nothing about. For Chrome, Firefox, or Edge, simply go to the setttings window of your browser to check your homepage setting.

Microsoft issues emergency Windows patch to disable Intel's buggy Spectre fix

If you’ve noticed any unexpected reboots or PC instability as a result of the recent Spectre patches, there’s a solution: Microsoft has issued an emergency Windows patch that rolls back the recent Spectre mitigations.
Confused? It’s a bit complicated. After the intial Spectre and Meltdown vulnerabilites were disclosed, both Intel and Microsoft hustled out patches to mitigate the problem. Unfortunately, Intel’s latest microcode updates—and the BIOS updates from PC makers based upon them—were themselves buggy, causing instability, reboots, and data loss in some PCs.
Microsoft’s latest patch (KB4078130) allows people with affected systems to download the patch via the Microsoft Update Catalog, which disables the mitigations for the “Spectre variant 2.”
Note that the patch notes specifically state that you should run this patch “if you are running an impacted device” (emphasis ours). In other words, if your system is working normally, don’t bother downloading this patch. This is what Microsoft calls an “out of band” patch, and it doesn’t appear that it will be made available via Windows Update, either.
Why should you consider it? Intel has warned previously that the faulty patch can sometimes cause data loss and corruption, and Microsoft is saying the same: “Our own experience is that system instability can in some circumstances cause data loss or corruption,” the patch notes state.
There’s another wrinkle, though. As part of the patch, Microsoft is allowing users to edit the Windows registry to toggle the mitigations on or off. (Instructions are here.) It’s possible to toggle Microsoft’s patch off, and then, when Intel solves its own patching problem, re-enable it. That scenario is actually what Microsoft recommends—again, only if you’ve noticed system instability and want to take action against it.
Toggling the mitigations on and off is also a feature of the latest InSpectre utility.
What should you do? There’s no one-size-fits-all answer to this question. But we can tell you what we’re doing: if a PC is working as expected, we’re leaving it patched and in place. If you’re backing up your data (to the cloud or an external drive) chances are your most crucial data will be saved in case your system goes down unexpectedly. Obviously, install Microsoft’s emergency Windows patch if you’re running into system issues. There’s no perfect solution—if you’re more paranoid than we are, feel free to deploy the patch even if your PC hasn’t hiccuped.
Good luck, and be sure to check out PCWorld’s guide on how to protect your PC against Meltdown and Spectre. Operating system updates are just one part of it.
As Bleeping Computer noted, system makers such as Dell and HP also advise rolling back their own BIOS patches to an earlier version, which they’re redeployed. It’s all horrendously confusing for consumers and IT organizations alike. Fortunately, at least, there haven’t been any public cases of these vulnerabilities being exploited, Microsoft says.

What is a hybrid smartwatch? The ideal wearable for watch fans

You’ve heard of a watch, right? And you’re likely fully aware of smartwatches, and how the two differ. But you may have also read about hybrid smartwatches. Confused as to what a hybrid watch does? We’re here to explain everything, from what a hybrid smartwatch is and what they can do, to a few examples of the best out there.
What is a hybrid smartwatch?
A hybrid smartwatch is a fusion between a regular mechanical watch and a smartwatch, in that it combines some connected features with traditional watch mechanics. It doesn’t have a touchscreen, doesn’t usually require charging up every day, and doesn’t look like a piece of technology. It looks like a normal watch. If the Apple Watch, Samsung Gear Sport, or touchscreen Android Wear watches like the Emporio Armani Connected, don’t appeal because they don’t really look like watches, then the hybrid is your gateway to the smartwatch world.
Show, don’t tell
The best way to understand what a hybrid smartwatch does is to see and play around with one. The above photo shows off the Fossil Q Crewmaster. We chose it as our example because the design is based closely on an existing Fossil watch, which the company chose to augment with smart connected features. You can see it has an analog dial, traditional watch styling, and it’s slim and stylish.
It’s smart because it has Bluetooth connectivity built-in, and it pairs with your smartphone through an app. The app is available for iOS and Android, which means there’s a high chance whatever phone you have works with the watch. It’s not like the Apple Watch, which only works with the iPhone.
What does a hybrid smartwatch do?
The vast majority of hybrid smartwatches share similar functionality. A hybrid watch will track your steps, while the app works out calorie burn and activity time. Some watches will also track your sleep, but it’s not as common considering most people are unlikely to wear the watch 24-hours a day. The watch will alert you of notifications on your phone with vibrations, and some kind of visual hint about which app is alerting you.
The method for notification alerts varies. Fossil, for example, makes the watch hands zip around to point at a single number, which you designate to a certain app or contact when you first set up the watch.
For example, if email notifications are linked to the number 3, the hands will move to 3 o’clock on the watch and will linger there long enough for you to take a glance. Other watches do it it different, such as the NYSW GTS Activity Tracker, which has a dedicated sub-dial for notification alerts. Hybrid watches from Guess and Martian have a small LCD screen for alerts.
You can also expect features like alarms, world time zones, and a programmable button that can be configured for different functions. This can include working as a remote shutter for your phone’s camera, for music control, or to make your phone ring in case you can’t find it.
Don’t expect most hybrid smartwatches to run apps, have watch faces you can change, or include more complex features like a heart rate sensor (though there are some like the Nokia Steel HR).
No charging?
Because most hybrid smartwatches don’t have a touchscreen, they don’t consume anywhere near the same degree of energy as one that does. Paired with Bluetooth Low Energy, a hybrid smartwatch can usually survive on a coin-cell battery, and therefore doesn’t require nightly charging.
The battery can last up to six months before it needs replacing, which can be done at home, and for a very low price. This makes hybrid smartwatches perfect for anyone that wants to avoid owning yet another device to recharge every day.
Anything else?
Because a hybrid smartwatch doesn’t deviate very far from traditional watch styling and design, you get many of the benefits associated with mechanical watches. Almost all are water resistant, and usually down to at least 5ATM (underwater up to 50 meters), not just a simple IP68 rating (limited to about 1.5 meters), and the standard size lugs mean you can pick and choose your own straps. Also, because the designs are more watch-like, there’s greater choice for women in the hybrid smartwatch world.
Finally, because hybrid smartwatches aren’t as technically complex as a full smartwatch, they’re often much cheaper.
