Vivo's in-display fingerprint reader won't play nice with screen protectors


It's only been two weeks since Vivo's latest attempt with an in-display fingerprint reader on a smartphone, and even though it didn't work perfectly for us, the company thinks it's ready for prime time. In China, consumers will soon be able to use this cool feature on the new Vivo X20 Plus UD, which is available today for 3,598 yuan or about $560, and it'll be shipping from February 1st. As the "UD" in the name implies, the fingerprint reader here has been moved from the rear side to underneath the display, courtesy of Synaptics' Clear ID sensor.

Apart from the special black-and-gold design, this device is otherwise identical to the original X20 Plus. You'll find the same 6.43-inch 2,160 x 1,080 (18:9) AMOLED screen, a Qualcomm Snapdragon 660 chipset, 4GB of RAM, a 3,905 mAh battery, a 12-megapixel-plus-5-megapixel f/1.8 dual camera on the back and a 12-megapixel f/2.0 camera on the front. As for storage, the X20 Plus UD here only comes in a 128GB flavor, and you can add up to a further 256GB via a microSD card. What makes both models stand out from other mid-rangers is their ES9318 DAC to please the mobile audiophiles -- something that Vivo is best known for doing over the years.

One interesting point addressed by Vivo today was whether a screen protector would get in the way of the in-display fingerprint reader. Well, that depends: it's actually fine as long as the screen protector doesn't exceed a certain thickness, otherwise it will affect the fingerprint's reflection as seen by Synaptics' optical sensor. To save us the trouble, the X20 Plus UD will come with a film that works, though if you need a replacement, chances are you'll have to buy one from Vivo to ensure compatibility.

While not everyone uses a screen protector, Senior Mobile Editor Chris Velazco had previously pointed out the potential issues with the in-display fingerprint reader when the screen is scratched or cracked, so it may actually be worth the additional protection on such a device. On the other hand, though, it'll be interesting to see how well this feature holds up as the unprotected screen ages over time. Either way, if the in-display fingerprint reader does end up becoming a popular feature, then the screen protector manufacturers better be ready for it.

Evernote cuts staff as user growth stalls

Image
Note-taking app Evernote has fallen on hard times of late, culminating in its latest spate of job cuts impacting 15 percent of its workforce (54 employees). CEO Chris O' Neil -- an ex-Googler who took the reins in 2015 -- announced the firings at an all-hands meeting earlier today, reports TechCrunch . In a message on the Evernote blog , O' Neill admitted he'd set "incredibly aggressive goals" for the company in 2018. He continued: "Going forward, we are streamlining certain functions, like sales, so we can continue to speed up and scale others, like product development and engineering." The layoffs follow an exec exodus just weeks ago and the company's recent brand refresh (complete with a refined logo and wordmark). But critics are more concerned about its product, especially the free tier, which they claim lacks the perks to...

The best air conditioner

After six summers of researching, testing, and recommending window air conditioners, we've learned that quiet and affordable ACs make most people the happiest—and we think the LG LW8016ER will fit the bill in most rooms. This 8,000 Btu unit cools as efficiently and effectively as any model with an equal Btu rating, and runs at a lower volume and deeper pitch than others at this price. Little extra features like a fresh-air vent, two-axis fan blades, and a removable drain plug help set it apart, too. The LG LW8016ER is a top choice for an office or den, and some people will find it quiet enough for a bedroom, too. If our main pic...

We won't see a 'universal' vape oil cartridge anytime soon

Image
Pre-loaded cartridges of cannabis concentrate are currently among the most popular means of consumption, and for good reason. They're discreet to use and easy to handle, a far cry from the dark days of 2016 when we had to dribble hash oil or load wax into narrow-mouthed vape pens by hand. But, frustratingly, an ever increasing number of oil cartridge manufacturers employ one-off design standards so that their products won't work with those of their competitors, thereby locking customers into proprietary ecosystems. We've already seen this with nicotine vaporizers -- which has a seen a massive rise in "pod systems" in the last few years, each outfitted with a unique canister and battery built to be incompatible with those of their competition. Is it too late for the burgeoning cannabis industry to set a universal standard for their product designs? ...
