Helio Mysto Review

  • Weird key design; gets hot easily; high learning curve


Helio is one of the few indie phone operators around, and the Mysto is the latest in its line of stylish, youth-oriented units. It is lightweight and multimedia friendly, but some will find it too focused on next-gen features and not friendly enough for day-to-day, mundane tasks like quick calls.

Features and Design

Despite its multimedia leanings, the Helio Mysto is small and compact; it will fit in one’s palm. Designed like a traditional slider, the top level is almost all vertical screen, about one and a half inches across by two and a half inches tall. The high resolution makes visuals bright and colorful. At the bottom of the screen are a slightly raised, round navigator pad along with two menu buttons, a call button and a cancel/backtrack key. Use your thumb to slide up the top and it exposes the bottom level with a good-sized flat keypad. (It also makes a loud, cartoon-inspired “boing!” noise, just to make sure you know the top was moved.) The numbers are fine, but the keypad gets unusually hot when it is charging – to the point where you may suddenly move away your thumb. In fact, the whole phone seems to run warm when plugged into the socket. It cools almost immediately after it is unplugged though.

The deep blue Mysto has very few extra buttons. On the left side is the volume control as well as the headphone/USB jack. On the right side are the power button and the camera key. There is a pinky nail-sized lens and an equally large flash on the back. It has 106 MB of internal memory, and can expand to 4 GB with an optional microSD. It is also Bluetooth compatible.

The Mysto runs on a fast 3G network, something that shows when browsing the internet or downloading videos. A minute and a half YouTube clip downloaded in about ten seconds – faster than some computers – and the visuals and audio were very nice. Some videos can be watched widescreen by pressing the appropriate menu key and turning the phone on its side. Multimedia power is perhaps the only truly compelling reason to buy the Mysto, so automatically add a microSD card to your purchase.

microSD aside, the Helio Mysto comes with all the necessary physical accessories: a power plug, a USB cord and a solid pair of Samsung headphones. (While part of the Helio umbrella, the Mysto is actually manufactured by Samsung.) It also comes with a simple, well designed help booklet and a CD with a more detailed manual in PDF form. The only disappointment was the lack of music software, something that could have easily been included on the disc. The 20 MB music suite must be downloaded separately from

Setup and Use

Making a phone call on the Mysto is initially complicating. The keys are sensitive, so it takes a few tries to not double or triple input a number, and calling the actual number requires hitting the small call button located by the flat dial. It just doesn’t seem intuitive. Add in its heat-prone temperature while plugged in and doing a quick phonecall can suddenly become laborious.

The Helio Mysto really shines in the multimedia department. Press the Left menu key and nine different icons pop up: Customize, Surf, Snap, Games, Apps, Message, Plan, Video + Music and Contact. Customize, Games, Contact and Plan (a.k.a. calendar) are what you would expect.

Surf takes you to the Helio Internet gateway with fast access to MySpace, Facebook, YouTube and other traditionally anti-phone websites. Helio actually worked with the companies to create special versions of their websites, and the results have little-to-no loss of power.

Snap is the camera function, and its 2 Megapixel power is fine, especially with the flash included on the back. Snap can also be accessed quickly using the camera button on the right side. The visuals are slightly above average, and the Mysto will automatically assume you want to send it to someone after its taken – by default a digital mailing screen will pop up for easy email attaching or uploading to a Flickr website account.

Apps features many of Mysto’s unique features, including Buddy Beacon, which shows you if you are in proximity to one of your Helio-subscribing friends, and Garmin Mobile, a portable version of the popular GPS system. As the case with many multimedia phones today, some of the services run a la carte – and at a high price. For instance, the Garmin Mobile runs $9.99/month or $2.99/day USD. No trial is offered. However, the equally sturdy Google Maps is included free of charge, and while it lacks the visual robustness it has on, say, the Apple iPhone, it is a fast, accurate direction giver. Furthermore, the Mysto’s built-in GPS sensors allow Google Maps to give pinpointed directions from wherever you happen to be (without having to type in your current location).

“Message” lists text messages as well as email options. The Mysto is compatible with Yahoo!, AOL, Windows, GMail, Earthlink and others. Sending a brief text message with a recently snapped picture took thirty seconds from start to finish.

Finally, Video + Music run as smoothly as expected. The regular speaker is fine, but the Samsung headphones are equal to what you’d get from a MP3 device. As mentioned earlier, some videos have the widescreen option.


The Mysto runs $320 USD, but new Helio customers – who agree to a two-year commitment – can buy it for $149. A few hundred dollars is reasonable considering its multimedia power. All Helio plans offer unlimited data, which includes text and Internet, and start at $65. It currently has an unlimited minutes deal for $99.

The internal 100 MB of memory is a good start, but you’ll eventually want to add a microSD card to the budget.


The Helio Mysto is an original, good-looking phone, packed with rare multimedia features, but the awkward design, heat-prone keypad and counterintuitive calling system make it less attractive than similar smartphones. It’s hard to justify the device on cool multimedia options alone.

Samsung Galaxy A53 5G hands-on review: Your long-term partner
Rear view of the blue Samsung Galaxy A53 5G.

Samsung has overhauled its great value midrange A-Series devices, launching the new Galaxy A33 5G and Galaxy A53 5G. At first glance, both look identical to each other, and arguably no different from the Galaxy A52 5G’s lovely design, but there’s a serious focus on longevity here with various changes to the spec that makes the new lower price even more tempting. I had the chance to try both phones out a few days before the launch.
Galaxy in your hand
The dimensions of the Galaxy A33 5G and Galaxy A53 5G are almost identical, and both are available in the same four colors, making the only immediately obvious way to tell the difference between them on their fronts. The Galaxy A33 5G has a teardrop selfie camera cutout, which Samsung calls Infinity-U, while the Galaxy A53 5G has a circular hole-punch selfie cam, called Infinity-O. There is a slight difference in weight, but as it’s only a few grams you won’t really notice.

The textured rear panel provides plenty of in-hand grip and has a pleasing warmth to it. The camera module blends into it for a smooth, classy finish. There are four colors, a pair of ordinary black or white models, along with a pretty sky blue and an unusual peach finish. I liked the sky blue a lot and was pleased the peach-ish version didn’t stray too far into the overdone pink territory. They give the design a fun, modern twist.

Motorola Edge Plus (2022) hands-on review: Far from perfect
Motorola Edge Plus 2022 on a background with multiple shades of blue.

The Motorola Edge Plus (2022) is the company's latest smartphone that aims to counter the likes of Google Pixel 6 and the Galaxy S22 with flagship specs and a price to match. The Edge Plus (2022) is fitted with vanguard hardware inside, but has a rather bland external appearance that hasn't been updated much since the Motorola Edge (2021). Upgrades include the Snapdragon 8 Gen 1, the latest and arguably most advanced chipset for Android phones, a 144Hz OLED display, dual 50MP cameras on the back, a 60MP camera for selfies, and support for wireless charging.

With these new flagship-level features, the Motorola Edge Plus (2022) finally feels primed to compete with the likes of the Galaxy S22. Motorola also makes some compromises that I will pinpoint in this article. Here are my observations after spending a few hours with Motorola's first flagship smartphone of 2022.

DJI Mavic 3 hands-on review: The long-awaited return of the king
dji mavic 3 hands on review 18 of 21

It's been a long time, but the king has returned. Since its predecessor’s release in 2018, we've seen DJI roll out several exciting drones that have redefined the space. They've managed to attract first-time pilots with the Mavic Mini series while giving enthusiasts something to sink their teeth into with the Mavic Air 2 and Air 2S. Without question, the focus was on the entry-level and mid-range market, but with the announcement of the DJI Mavic 3, it’s a return to the flagship space.

While I enjoy piloting drones and capturing the occasional aerial shot, it’s not something I do full-time and make my priority. Honestly, I simply enjoy stitching together short clips of places where I visit and posting them on social media -- that’s all. But let me just say that, after spending a week with the Mavic 3, it really cements the idea that it’s unquestionably the flagship drone in DJI’s Mavic series. Just note that I was running a pre-production firmware, so not all the drone’s new features have been tested.
See closer, while farther
There are a lot of new features that accompany the DJI Mavic 3, but if there’s one that stands out to me, it’s the Hasselblad dual-camera system. Instead of having two separate versions like its predecessor, the Mavic 2 Pro and Zoom, DJI brought the best of both worlds to its Mavic 3 -- and let me tell you, it’s a satisfying union because of its versatility.
