The Galaxy S8's iris scanner fixes the one thing that made it suck on the Note 7

One of the coolest features from the Galaxy Note 7 (RIP) is back and better on the Galaxy S8 and S8+.

I'm, of course, talking about the Note 7's iris scanner. Samsung introduced the iris scanner on the Note 7 as an alternative way to secure the phone, but it wasn't without its flaws.

Fast as it was, activating the iris scanner was kind of a pain in the ass. Allow me to quote myself:

"I found it faster to unlock the phone with a fingerprint than waking up the phone, swiping to bring up the iris scanner/PIN (or pattern)/fingerprint unlock screen then getting my eyes scanned."

And:

"...it sometimes had trouble detecting my smaller eyes, asking me to "open eyes fully," and reflections in my glasses always interfered with the scans."

Samsung's fixed this complicated three-step process on the S8 and S8+.

First, it's now only two steps: Wake the phone up by pressing the power button or virtual home button and then look into the IR sensor on the top bezel. No more, swiping up to bring up the iris scanner preview/PIN lock screen.

Second, you don't even need to have the iris scanner preview window any more, which means you don't need to try to line up your eyes with the two circles on the screen. By disabling the iris preview, the iris scanner is now actually useful.

Weirdly enough, Samsung's added a bunch of different cartoony faces that you can select instead of the standard two circles. So you can set up the iris scanner like this:

New photos show Tesla's massive Nevada factory is coming along

'Guess we shouldn't be too surprised that the what's going to be world's largest factory...continues to get larger. Tesla's Gigafactory, a gleaming white structure amid the muted browns surrounding Reno, Nevada, seems to be coming along, according to photos snapped by NM Group, a company that describes itself as specializing in "surveying and mapping, asset modeling and management, and engineering." The group was recently mapping the area for potential power lines on behalf of an electricity company, according to Tim Hustwayte, a senior client manager based in the United Kingdom. The route took them close to the Gigafactory, and they got some shots that appear to show the factory having bulked up since Tesla's battery cell began rolling off production lines at the start of the year. The Gigafactory employed nearly 3,000 people at the start of the year, less than half of how many people are expected to be employed there...

The Freedom 251 isn’t dead, it’s returned as the Freedom 420 4G feature phone for Rs 420(6.48$)

As we’re all aware by now, the Freedom 251 smartphone turned out to be a sham. The makers of the smartphone, resellers to be precise, were unable to follow through on their promise of delivering a smartphone at Rs 251 to the Indian public. Practically speaking, building such a smartphone was impossible to begin with. The bill of materials alone would place the cost of the device at over Rs 1,000 and despite claims of unnamed “partnerships” and tax breaks under the Make In India initiative, it would have been impossible to bring down the price of the smartphone and the plan fizzled out. Reality struck a harsh blow to the company and it’s offices have since been shut down. The original owners have also quietly disappeared and at least one has been arrested. It now appears that the company never gave up trying. We’ve learned that the company, now under new management, has taken a more realistic approach to the problem and have come up with yet another outra...

Samsung's Galaxy S8 has a killer feature that nobody's talking about

Samsung's Galaxy S8 is packed full of awesome new features like the new larger screen, face recognition and Bixby AI assistant. But there's one pretty killer feature on the phone Samsung didn't bother to mention at its Unpacked event on Wednesday. That feature: a built-in GIF maker. It's not like the Smart Select GIF maker that first appeared on the Galaxy Note 7 and later trickled to Samsung's Galaxy Tab A and Galaxy Tab S3. It's even better. Located within the Gallery app's video section is a little GIF-creation tool that lets you convert a section of any video (even ones you record) into an animated GIF. Unlike the the Smart Select feature on the Note 7, you don't need to manually select a specific area on the screen to capture. Just open up a video within the Gallery app, tap on the GIF icon, and then move the slider along the bottom to select the section of the video you want to convert into a GIF — and that's it!...
