What tech products or categories are you most passionate about?

Everything that remotely falls under the umbrella of technology gets me excited, but I've been directing my attention more towards the day-to-day computing devices like laptops, desktops, and smartphones that are shaping the future.

How long have you been interested in technology?

I may have started covering the technology space "officially" in 2016, but I've been obsessed with technology and gadgets for as long as I can remember. I was lucky enough to get my hands on a Motorola Razr V3 in 2006, shortly after which I started writing about technology on my blog.

What was your first computer?

I've been dabbling with computing devices for as long as I can remember, but it wasn't until 2010 that I built my first computer. It coincided with the launch of Intel's 2010 Core processor family, and I vividly remember how excited I was to finish the build and install a copy of GTA IV. The good old days when choosing the right component or finding a stable game to run wasn't a chore.

The Galaxy S23 and the Galaxy Z Flip 4 are two of the best Samsung phones you can buy right now. Both phones, however, have some significant differences, especially in terms of the form factor, so you may lean towards one or the other depending on your preference. The Galaxy S23 is a regular flagship with a conventional glass slab design, whereas the Galaxy Z Flip 4 is a foldable phone that has improved a lot over the past few iterations. But there's more to the Galaxy S23 and Galaxy Z Flip 4 comparison than the form factor, so let's see how these phones stack up against each other.

Most people tend to prioritize choosing the best CPUs and the best graphics card over anything else while building a PC. The decision of picking the best PC case is often overlooked and is usually considered an afterthought. While the core components like the CPU, GPU, motherboard, etc. are important for the build, the PC case is perhaps the one that should be picked first. A chassis is more than just a box to put your PC components and hide the cables. Not only does it give an identity to your build, but it also plays a crucial role in determining what components can fit inside. Not to mention, it also influences factors like thermals, noise levels, and more. In this article, we'll try to break down a few important things and tell you how to pick a PC case.

Samsung made a splash earlier this month with the Galaxy S23 Ultra, which turned some heads with top-tier specifications and upgraded cameras. The company has its eyes set on the top spot of the best phones list, but it has to fight through competitors like OnePlus, which already has a flagship ready to lock horns with the best — the OnePlus 11.

2023 is off to a great start for smartphone enthusiasts, as we already have two big reveals from Samsung and OnePlus. Samsung was technically the first to come out of the gate with a global launch, but OnePlus quickly followed it up with its new flagship a week after. We have three new flagships in the Galaxy S23 lineup, but we're going to pick the regular Galaxy S23 model for this comparison to see how stacks up against the OnePlus 11 5G. Both of these phones are similarly priced, so it'll be interesting to see how they compete in the sub $1,000 smartphone category in the U.S. If you're on the fence about buying either of these phones, then here's a Galaxy S23 vs OnePlus 11 comparison to help you with your purchase decision.

Android is a relatively simple operating system to use, so you won't have a hard time getting used to Android phones if you are coming from a different OS. All the settings and customization options, however, can be a bit overwhelming for new users. Google does a pretty good job of walking you through all the basic steps during the setup, so we doubt you'll have any issues setting things up and getting to the homescreen. But once you're done with the setup, there are a few things you can do to start using the phone to its fullest potential. That's exactly what we're going to help you with. So, grab your phone, sit back, and check out the first ten things you should do with a new Android phone!

From worst to best: Here's how the Samsung Galaxy S series stack up in 2023

Samsung's Galaxy S series has had quite a journey since 2010. Here's how they stack up!

Samsung has become synonymous with premium mobile experiences worldwide, and it's hard to ignore its dominance as a strong force in the Android smartphone space. The Galaxy S series flagships didn't find them themselves atop the pile of iPhone alternatives overnight, though. The company has more than a dozen phones in the series, and it had to go through a few iterations before making it to the big leagues. Not all the Galaxy S series phones were created equal, so we decided to take look back and rank them from worst to best. It's worth mentioning that all these phones were among the best in the market when they arrived, so "worst" in this context only means they're not as impressive as the others mentioned in this collection.

These are the most useless features introduced in Galaxy S series phones over the years

Samsung has had a terrific run in the flagship smartphone space with the Galaxy S series, and it continues to ship some impressive devices like the Galaxy S23 series. The company gets a lot of things right with its flagships, but it has shipped its fair share of questionable features that left us scratching our heads. A lot of them were a part of its older flagships in the Galaxy S series when the company was open to taking bigger risks to appeal to the masses. We're talking about the decade-old Galaxy flagships like the S4 and S5, so you may not remember many of these features now. But we recently highlighted some of the best Galaxy S series we saw over the years, so it would only be fair to shed light on some of the most useless features we used in the Galaxy S series flagships. Let's dive in!

Apple's iPhone 14 Pro models now have new rivals in Samsung's Galaxy S23 series. The new Galaxy flagship phones aren't radically different from the last year's model, but they pack updated internals and some new additions to compete for the top spot on the market. We've already seen how the regular Galaxy S23 model stacks up against the iPhone 14, so now it's time to see how the higher-end flagships compete with one another.

The best thing about being in the Android ecosystem is that you get to use phones from different manufacturers who like to put their own spin on the software. Google's Pixel phones, for instance, get exclusives like call screening and Now Playing, whereas the OnePlus phones have the coveted alert slider. It's the same with Samsung phones, too, and the Galaxy S series, in particular, brings a lot of good features to the table. We've seen a lot of these Galaxy S series features come to life over the years, so we decided to highlight some of the best ones in this post.

Best Microsoft Surface Duo 2 cases in 2023

Microsoft's dual-screen phone has been out for a while now, and it has gotten better over the last few months with a bunch of updates. It's also significantly cheaper now compared to its launch price, so it may be worth considering in 2023 if you're looking to try a different phone. But keep in mind that it's a dual-screen device that's more fragile than your ordinary slab phone, and repairs can be quite expensive for a device like this. You'll definitely need to protect it with a case to ensure it stays in a good condition. If you're wondering which case to buy for the Surface Duo 2, then here are some good options to consider.

The importance of password managers cannot be understated in 2023, especially if you have a growing list of online accounts. A password manager will not only keep you safe online, but it'll also make it easier to create and store strong passwords. I recently signed up for a password manager and came across a host of options to choose from, including built-in password managers, which are featured in most web browsers.

"OnePlus phones aren't exciting anymore." That's the first thing I said when I booted the OnePlus 10 Pro recently to give it a second chance before its successor arrived. I know a lot of you reading this post agree with me because OnePlus hasn't produced something different from everything else on the shelf today. Its devices have been exceedingly incremental for the past few generations. Then why do I have my eyes set on the OnePlus 11, you ask? Well, that's because there are a few things different this time around.

The Galaxy Watch 4, in particular, was very easy to recommend, and it made it to our collection of the best smartwatches. It wasn't without its flaws, though, so Samsung announced the Galaxy Watch 5 model in due time to fix many of them and improve the overall user experience.
