one super neat thing about escalators is that even when they're turned off they
still function as a regular old staircase but what about your phone why
does the screen go black when you turn it off instead of it showing my
wallpaper forever well it could if you used an e-paper display like the kingrow
k1 a full-on smartphone promising 400
hours of standby battery life but are there enough benefits to consider
switching to e-ink or is it more like e-stink
the fujitsu scan snap ix 1500 allows users to easily manage edit and scan
documents business cards receipts and photos and well pretty much anything
check it out at the link in the video description
we're gonna get to all the downsides about this phone in a minute but first
the benefits who would want this thing to begin with well the company's
indiegogo campaign advertises it as being optimized for eye health because
as long as you're in a brightly lit room the phone doesn't have to emit any
harmful blue light for you to see the screen that's because unlike the lcd or
OLED screens on most phones e-ink displays don't work by shining light
through a pixel and into your eye instead they're what's called reflective
displays where the light around you either reflects off or is absorbed by
the white and black parts of the screen just like most other objects around you
like my t-shirt or this banana the k1 is certainly easy on
the eyes and i personally love reading on it and it even comes with a kindle
app pre-installed sure the phone is only black and white but that can actually be
seen as another benefit bright saturated colors are super stimulating to the
brain but are relatively rare in nature your phone and its attention buying apps
is full of bright colors that contribute to the urge to pull it out even if it's
just for a few seconds while you wait for an elevator to arrive or your game
to load switching your phone to grayscale is commonly recommended as a
strategy for fighting tech addiction because it makes your phone less
interesting but the k1 takes this a step further
because there's no way to switch the colors back on in a moment of weakness
it's like this forever and finally i could also see this phone being useful
for certain occupations because unlike regular screens that can be near
impossible to see in direct sunlight this one actually gets easier when it's
brighter and the battery life can be a lot better depending on your use because
although it does take energy to update the screen to create an image retaining
that image like the wallpaper takes no energy at all that's how the k1's 3100
milliamp hour battery can claim an amazing 400 hours of standby if the
phone's just sitting in your work trucks glove box but only a much more modest 20
hours of talk time which brings us to what it's like to actually use this as a
phone it's pretty bad mostly because of two interrelated
problems app support and latency the k1
does not support the google play store so you can't easily download apps
instead you're supposed to use the apps that come pre-loaded with the phone
or any that become available later on when kingrow's own app store finally
launches in what we expect to be october and maybe the people who want this phone
don't really need that many apps anyway but the limited selection along with the
dated looking ui and the jelly bean era
app icons make the k1 feel
like a monochrome feature phone from the early 2000's but the reason they've made
their own custom version of Android 8.1 and do not support the play store again
comes back to the screen the e-ink display actually cannot pass google's
device certification because they're just not designed to display animations
or videos at high frame rates and by high frame rates i mean
anything above 10 FPS really
now i gotta hand it to king girl a little bit because unlike most e-readers
that blink every time the screen updates showing the inverse of the image then
all black then all white the k1 is a little more choosy for example on the
kind of always on display the screen only does a partial update of just the
clock though it it does still blink which is actually pretty distracting
when it's sitting on your desk i keep thinking that i have notifications or something but if you open up the browser
and go to youtube you can actually watch a video the higher frame rate comes at
the cost of horrible horrible ghosting that gets wiped away by a full blink
every minute or so but you can't do it another thing you can do is take photos
with the 8 megapixel rear camera you can even use one of several built-in filters
you just won't know what any of them look like until you view them from
another device oh and the uh for selfie fans this
prototype has a front camera but the final device will not
so should you buy this phone well unless you're just super gung-ho on having
basically a smaller kindle that can make phone calls
probably not i mean as far as mid-range phones go with just 16 gigabytes of
storage two gigabytes of RAM and a mediatek helio p23 i think it's way
overpriced at 350 us dollars i mean our redmi note 7 has better specs for half
the price but on top of that i don't even agree with their main claim about
eye health because the k1 does have a backlight you can turn it completely off
but it does have one which they claim does not emit blue light but it looks
pretty blue to me and i'll probably be using it when i'm scrolling my phone in
bed and that's actually worse than regular phones which nowadays
almost always have a night light mode so with all that said plus the fact that
ever present image retention makes the screen a perpetual palimpsest
i'm recommending a pass to all but the most avid e-paper fans
door peoples are so 1990s with a ring
video doorbell you'll know who's at your front door without ever getting up their
welcome kit includes their video doorbell too their spotlight cam a
battery and a solar security sign the video doorbell 2 has a motion sensor
camera it's 1080p with 160 degrees of vision it supports two-way audio and
it's either battery or 8 to 24 volt ac
doorbell wiring powered the spotlight camera features 1080p hd video two-way

audio on the ring doorbell 2 is great and you can turn away unwelcome guests
tell them to come right in you know yo you're unwelcome but

delivery driver to not run away after the second knock on the door no no i'm
