This smartphone has a secret. Flip it over, and there’s a second screen on the back

Add as a preferred source on Google

Most modern smartphones have got two cameras, and some have even got space for two SIM cards, but very few have two screens. The Siam 7x is a new crowd-funding project for a smartphone that has all three of those features, and the company says it’s the first to introduce dual-screen technology to smartphone buyers in North America.

Kickstarter campaign ends, Indiegogo begins

The Siam 7x initially started out as a Kickstarter project, but was removed following a copyright claim against the phone’s rear E-Ink display. The company provided Digital Trends with the following statement, saying:

“The Kickstarter campaign for the Siam 7x smartphone has been suspended due to a minor copyright infringement issue with the spelling of its E-Ink display feature. We have quickly resolved the issue and have re-launched the crowdfunding campaign for Siam 7x dual-screen smartphone. This will not affect our promise to deliver the smartphone to backers in early December.”

Except this time, the crowd-funding campaign has relocated to Indiegogo, and can be found here. The deals appear to be identical, and the specs of the phone remain the same.

Why two screens?

The idea is to make multitasking easier, and to ensure we have crucial information instantly visible on our phones, something it achieves with a normal IPS touchscreen on the front and an E-Ink touch panel on the rear. While Siam may be the first to introduce such a device to the U.S., we’ve seen this technology before on the Yotaphone and Yotaphone 2 — the latter of which had its U.S. release plans cancelled.

Viewed from the front, the Siam 7x definitely has a design reminiscent of an iPhone, but that all changes when you flip it over to see the second screen. The 720p front screen measures 5-inches, while the 960 x 540 pixel E-Ink rear screen is slightly smaller at 4.7-inches. A MediaTek octa-core processor with an unknown amount of RAM powers the phone, there’s a 16-megapixel camera on the back, and an 8-megapixel camera on the front.

The rear screen shows notifications, and supports little widgets for functions including the weather, music controls, and you calendar. It also works for reading ebooks, and for displaying maps. Android Lollipop is displayed on the front screen, and from the screenshots it does have a custom user interface over the top. Other Siam 7x features include a 2100mAh battery, 4G LTE connectivity, dual-SIM support, an FM radio, and Bluetooth 4.0.

If the dual-screen concept doesn’t get your blood pumping, then Siam’s Kickstarter benefits may do. Back the project for $420 and not only do you get the phone and a case, but you also get a lifetime warranty and a free upgrade to the next Siam phone. That’s the same with the $470 option, which also comes with a 32GB MicroSD card and a pair of heart rate monitoring earbuds. Pay $480, and the Siam 7x also comes with three months unlimited service in the U.S. provided by Jolt Mobile or Lyca Mobile.

The project is live on Indiegogo now, with a $50,000 target. If it gets funded, the good news is backers won’t have to wait years for the phone to arrive, as Siam says deliveries will take place from December this year. Despite the focus on the U.S. market in the campaign blurb, the Siam 7x will ship anywhere in the world.

The HONOR Robot Phone feels like the first phone I’d actually buy for its weirdest feature
I wanted a better workflow. HONOR built a robot.
HONOR Robot Phone Hands On First Impressions Review

When I was at Computex earlier this year, I shot a lot of Reels using my DJI Osmo. And don't get me wrong: that little camera is excellent. The stabilization is great, the video quality is good, and it is exactly the kind of thing you want when you're running around a trade show trying to make content. But then came the annoying part: transferring all that footage to my phone or laptop, moving it to the cloud, and finally getting it onto the platform I actually wanted to use. At some point, I remember thinking, "Why are there so many steps?"

Apparently, HONOR had the same thought. The difference is that while I just complained about it, HONOR went ahead and built a phone around the idea. The HONOR Robot Phone is, admittedly, doing a lot. It's a flagship Android phone, a miniature motorized camera gimbal, a robotic arm, and an AI playground all rolled into one. But after actually using it at IFA Berlin this year, I found myself caring far less about the novelty and far more about the camera. Because, honestly, this thing is really good.

Samsung Galaxy Z Fold 8 is an unabashedly bougie reader, but gosh, I can’t put it down
I am NOT telling you to spend $1,900 on it for reading books. And yet, here I am, surpassing my reading goals at an addictively quick pace.
Samsung Galaxy Z Fold 8

On an ordinary day, if you ask me what's the best e-reader device out there, my answer would most probably be one of Amazon's Kindle readers. I will most likely ask about your budget and your preferences before doling out a few recommendations. 

If you tell me that the Kindle is too restrictive, I would point you in the direction of a Boox slate, which comes in multiple sizes across a wide price bracket. In case you are inclined towards a phone-like reader device, the Boox Palma 2 or the DuRoBo Krono would be my suggested picks. And if you're chasing something light, tiny, and open, the XTEINK X4 would be my go-to choice.

Three reasons I’m still hesitant to order the iPhone Duo
Apple’s first foldable had me reaching for my credit card, but a few days of thinking changed my mind.
iPhone Duo on table unfolded

Apple unveiled the iPhone Duo at its “Surprise and Shine” event, and my jaw dropped. To be fair, I had a pretty good idea about the phone’s hardware, but the software polish and little nice touches Apple added everywhere made me instantly pull out my credit card. 

From the opening animation to the almost creaseless nano-texture display to the under-display camera to the IP68 water and dust resistance, Apple has certainly delivered with its first try at a foldable phone.
