Samsung Galaxy Watch 4 vs Galaxy Watch Active 2: It’s time for One UI Watch – XDA Developers



Samsung has announced the Galaxy Watch 4, and with it, Samsung is folding the “Active” moniker back into the main lineup. Compared to the Galaxy Watch Active 2, its spiritual predecessor, there are some big improvements. These come from both the software and hardware sides of things, and it’s kind of a big deal, not just for Samsung but for the broader Android ecosystem as well.

It’s got more RAM, more storage, a better processor, and a lower starting price. But not only that, there’s an entirely new operating system being used. Samsung is finally ditching Tizen in its smartwatches.

Hardware: The Samsung Galaxy Watch 4 beats the Galaxy Watch Active 2 in every way

The new Galaxy Watch 4 and Galaxy Watch 4 Classic have Samsung’s own Exynos W920 processor. It’s the first 5nm processor to go in a Galaxy watch. It definitely beats out the dual-core Exynos 9110 that was found in the Galaxy Watch Active 2. There’s no surprise there though. A newer processor is undoubtedly going to be a faster processor.

RAM is the same 1.5GB, but storage has been bumped up from 4GB on the Samsung Galaxy Watch Active 2 to 16GB on the Galaxy Watch 4. That battery is bigger too at 361mAh for the 44mm model, although the smaller model’s battery size is the same. The smaller one is actually 0.1g lighter though, while the bigger one is 0.3g heavier, something literally no one will care about because you won’t be able to tell the difference of 0.3g or 0.1g.

Indeed, everything is a bit better on the Galaxy Watch 4 than it is on the Galaxy Watch Active 2. It has a better processor, four times as much storage, and a bigger battery. While that covers the standard “feels faster”, let’s talk about things you can actually see and feel.

The screen has a higher resolution on the Galaxy Watch 4. It’s 450 x 450 on a 1.36-inch screen with the larger model (44mm or 46mm case depending on the one you choose) and a 396 x 396 1.19-inch display on the smaller one (40mm or 42mm). That gives it a 330ppi pixel density on either one, which is much higher than on the Galaxy Watch Active 2, which has a 360 x 360 screen on either a 1.4 or 1.2-inch size. In other words, things look sharper and prettier on the Galaxy Watch 4.

The Galaxy Watch 4 also has a new Samsung BioActive Sensor, which is a three-in-one sensor that detects heart rate (PPG), ECG, and bioelectrical impedance analysis (BIA). The Korean firm says the new sensor is groundbreaking, and indeed, it’s impressive.

Software: Tizen is gone now

Back at Google I/O, the company announced that it was rebuilding Wear OS, a much-needed improvement to a smartwatch OS that hasn’t had any meaningful changes in a very long time. One thing it promised was a unified platform that combines Google Wear OS and Tizen, the OS that’s been used on Samsung smartwatches.

We’re getting a taste of that new unified platform with the Samsung Galaxy Watch 4. It uses what Samsung is calling One UI Watch, and it’s meant to provide the best of both worlds. Those worlds, of course, are Google services and Samsung services.

Those Google services include apps from the Google Play Store. Indeed, with the Galaxy Watch 4, you get access to the ecosystem of Wear OS apps, rather than just the Tizen apps available for the Galaxy Watch Active 2. You also get Google Maps, and whatever else you’re missing. But it still works well with your Samsung phone, syncing your settings and such. It’s really meant to be the best of both worlds. But as a side note, the Galaxy Watch 4 does not work with devices that do not have GMS (Google Mobile Services), which means you can’t even pair it with an Apple iPhone or a Huawei device. The Galaxy Watch Active 2 remains compatible with Android and iOS, so there’s wider compatibility.

Conclusion: Should you buy the Galaxy Watch 4 or the Galaxy Watch Active 2?

The question of which one you should buy is always a tricky one, but that’s especially true of smartwatches. The answer is the Samsung Galaxy Watch 4, due to the much better hardware, and the software that has been tremendously improved. However, many smartwatch users go for deals. If this is your first smartwatch, you might not see the benefit of spending extra on the Samsung Galaxy Watch 4.

Here’s the deal though. Newer products are better than older ones, except in those rare cases where companies make dumb mistakes, such as no compatibility on non-GMS devices. With the newer product, you’ll also get better support. Indeed, don’t expect any new features to arrive on the Galaxy Watch Active 2, considering One UI Watch is the new thing moving forward.

    The Samsung Galaxy Watch 4 has a new BioActive sensor, and a new unified software platform called One UI Watch.

Ultimately, Samsung has some of the best watches that can be paired with most Android phones. The newer Watch 4 does not work with iOS, so if that’s what you’re looking for, you’ll want to see how it compares to an Apple Watch. The Galaxy Watch 4, and especially the One UI Watch software, just takes the Android experience to another level.

    The Samsung Galaxy Watch Active 2 still runs Tizen, but it comes in 4G models, or with your choice of aluminum or stainless steel.

Today’s Homes Need a Professional Electrician’s Touch



Credit: Ed Harvey via Pexels

Modern technology can be jaw-dropping at times, but it must be installed correctly and safely. There’s nothing worse than getting ready to show off one of the latest gadgets, only to see that it doesn’t work!

Professional electricians have the experience and knowledge necessary to ensure that the wiring tucked out of view works as it should, so what is visible performs the way it’s expected to. Let’s check out the different services electricians provide for your home.

Safely, Efficiently Wire Smart Homes

The idea of a Smart Home where people can control a room’s temperature from their phone did not exist when many homes were built. Whether your home is from a previous generation or you’re building a new one from scratch, professional electricians can ensure the wiring will safely and sufficiently power all your devices if you want Smart appliances in it.

The electrical requirements are not the same in a house designed to power the lights versus one that can charge a car in the garage. Even though some aspects of a Smart Home can be self-installed, if you’re confident enough, most laypeople don’t know how to install it optimally.

If you have multiple smart devices, it’s better to have them streamlined, so they can talk to each other and be interconnected. You want your speakers, thermostat, locks, and more to work effortlessly, and professional electricians make it easy.

If you’re going to be charging an electric vehicle at home, ensure your EV Charger is hardwired to the electrical panel. A certified, licensed, and insured electrician needs to confirm the installation meets certification requirements.

If you need an electrician in Pickering or anywhere in the Durham region to wire your home for modern technology, look for a family-owned business that can get the job done quickly and with excellent customer service. Family-owned businesses specialize in customer satisfaction.

Safety Matters Above All

It’s hard for laypeople to identify faulty or dangerous wiring when they see it, and it’s hard to see behind those walls. Professional electricians have the equipment to measure the rate at which electricity is conducted, so they can safely install your home’s lighting.

Whether you’re moving into an old home that may have outdated systems or building a brand-new house, hiring a professional electrician to inspect and install the wiring is essential. Confirm first whether they’re an apprentice, journeyman, or a master electrician, and double-check that the business is bonded, licensed, and insured.

The safety of you, your family, and your home may be at risk unless a professional electrician has inspected your home’s wiring and deemed it safe. You can’t get this peace of mind any other way.

A home ought to have lights that turn on brightly and safely, but it’s common to expect a lot more from our gadgets, given today’s incredible consumer technology. Make sure you have a professional electrician inspect and wire the home, so you can feel confident that everything will work smoothly and safely.

From ‘Bayonetta 3’ To A New ‘Kirby’ Game, The Latest Nintendo Direct Had A Lot To Offer – Forbes



What with Nintendo being a regular abstainer from the Tokyo Game Show, it’s not a huge surprise the company decided to make a bunch of announcements before that with their latest Nintendo Direct. However, the amount of things announced took us a bit by surprise.

The first major thing that has seemingly melted people’s brains, is the announcement of the upcoming Super Mario movie. Namely, the movie’s cast with Chris Pratt taking on the role of Mario and Jack Black as Bowser. Erik Kain covered this already in detail, so you should have a look at that if you want to know more.

The other big surprise was the reveal that Bayonetta 3 still exists and will be released next year (shown above). We also got to see some of how the game plays and it looks superb, especially the kaiju controlling setup.

Following that we had news that the Nintendo Online service is going to be extended this October to include Nintendo 64 and Sega Genesis games, and that both systems will be getting their own wireless controllers compatible with the Switch (shown above).

While I am not surprised to see the N64 finally make its way to the Switch, the Sega Genesis is a genuine surprise. Considering that when I was growing up that Sega and Nintendo were bitter playground enemies, having the Genesis on the Switch is just a bit odd, though entirely welcome.

We also got a look at what appears to be an upcoming open-world Kirby game, called Kirby and the Forgotten Land. Again, this looks great, and I get some proper Super Mario Odyssey vibes from the whole setup, but I had hoped to see a sequel to Planet Robobot at some point. Maybe one day.

In addition to that, Capcom revealed a DLC update to Monster Hunter Rise, called Sunbreak and set for release next Summer. It’s got a rather gothic look to it and I am sure this will ensure the Switch’s dominance in Japan for the next year or so.

Then there were a bunch of announcements for releases of games available on the Switch today. From the stealth launch of ports for classic Xevious and Pac-Man, to a gorgeous collection of Castlevania games from the Game Boy Advance era of the series. Not to mention the suitably amazing looking Actraiser Renaissance, being an HD remake of the classic SNES game.

Anyway, all that aside, this was a pretty heavy drop from Nintendo and if you are interested in watching the whole thing, then check out the Nintendo Direct video below.

The Morning After: The EU’s grand USB-C plan – Engadget



Like a band with too few hit singles, the European Union is resorting to playing the classics over and over again. The bloc has, like clockwork, tabled a proposal for legislators to think about maybe possibly having a debate about if it’s worth creating a common charging standard.

This has happened more than a few times before, as it pushed micro-USB as a voluntary standard in 2009 and tried to pass it into law in 2014. And in 2018. And it started this process again in January 2020, although some world-shattering event got in the way of that process.

The new proposal would require that “all smartphones, tablets, cameras, headphones, portable speakers and handheld video game consoles” would use USB-C for charging. The law would also “unbundle” the sale of chargers from devices as a way of reducing e-waste.

EU officials are also proposing for technology manufacturers to harmonize their fast charging technology to ensure continuity between devices. Officials added that such harmonization would prevent “different producers unjustifiably [limiting] the charging speed” which isn’t really the issue here.

Naturally, the obvious target for this is Apple, which has already come out against the proposal. Perhaps it will be this, rather than anything else, that prompts the arrival of the long-rumored portless iPhone.

This proposal may, like its predecessors, wind up dashed against the rocks of politics never to be heard from again. But, even if it does succeed, the transition period is going to be sufficiently long that no company needs to worry about this being some sort of cruel surprise.

It aims to eliminate the worst of Amazon’s warehouse policies.

California governor Gavin Newsom has signed AB-701 into law, a bill which aims to regulate productivity quotas for warehouse workers. Inspired by the horror stories of poor treatment coming out of Amazon’s logistics facilities, the law will make quotas more transparent. Workers will also be able to say no to doing work which isn’t in compliance with health and safety laws and can’t be fired for failing to meet an unsafe quota. The law, which comes into effect on January 1st, 2022, could improve the quality of life for thousands of employees. Or not.

The chips are the size of a grain of sand.


Northwest University’s John Rogers is back in the headlines after his team created a microchip the size of a grain of sand. The team say that the chip, which could be made from biodegradable materials, would be carried on the wind like a cottonwood seed. It’s hoped that the chips will host sensors which could track air pollution or the spread of airborne diseases. If the team can work out the kinks in the idea, the chips could become vital tools for environmental monitoring in the future.

‘Lower Decks’ plays around with the knottiest of philosophical problems.

Lower Decks


Humanity has yet to satisfactorily answer the question about how many rights, if any, an artificial intelligence deserves to have. It’s an issue that the latest episode of Lower Decks blows the odd raspberry toward during its latest episode. Mariner and Boimler wind up babysitting a sinister AI on its way to the Daystrom institute, with plenty of time to consider the issues. Or not, as it is, after all, an animated sitcom. Once you’ve watched the episode, however, come check out Kris Naudus’ deep dive into the episode, the highlight of which is the return of Star Trek legend Jeffrey Combs to the series that loves him the most. Kris also took a deep dive into this week’s episodes of Marvel’s What If and Star Wars: Visions if that’s more your sort of thing.

If you want to save money, embrace the wire.



Razer has launched a cheaper version of its popular Kaira gaming headset that ditches the wireless connectivity to save money. The Kaira X costs $60, down from the $100 of its older sibling, and ships with a 3.5mm cable for connecting to your console of choice. Otherwise, however, you’ll still get the same 50mm “TriForce” drivers, cardioid boom mic and on-headset controls. If there’s one other compromise, it’s in the colorways: The PlayStation-compatible version is only shipping in a matching (and very fetching) monochrome.
