    I'd buy a phone like this if they improved the framerate and it had a more decent cost. I'd use a normal phone for picture taking, social media managing, and this phone for messaging, calling, reading... things that I do most of the time anyway.

    02:37 Let's talk batteries.🔋400 hours of standby time is almost 17 days. 20 hours of talk time is about 5% an hour.
    Why is this considered exceptional? Every phone I've owned has 13 to 20 days of standby time. Or more. My tablets go even higher. And I can add a power bank for $20 to double or triple those numbers again. 5-6% an hour for call time is normal.
    These aren't theoretical maximums. They're the actual numbers I get when I measure my devices. (0.1-0.3% an hour when idle).
    I don't get the point of their claims at all. You can buy a second battery or a power bank to completely negate any issues with running out of juice, and it doesn't cost $350. That's a heck of a lot to pay for an e-ink screen. Heck, some people are saying this would be good for an emergency phone. If you need to conserve battery just turn it off until you use it.
    Something doesn't add up here.

    I leave my phones amber nightlight on; you don't even notice it after a few minutes. If I turn the nightlight off now, it is so harsh, and I immediately turn it back on. I also keep brightness at 15%. I can see the screen fine unless I'm in direct sunlight.

    This would be a really great audible/kindle/caller/texter device, but not so much for interactive apps. Would be ideal for people looking to lower-tech their lives or control their media intake... I might have to get one.

    Lol. When I bought my first smartphone, I nearly immediately purchased fallout theme app, and colored everything in dull green. My phone holds usually more than 2 days. I guess, it's because I'm not so interested in checking it every other second. Not like I have there to check something.

    As long as e-ink displays are under the monopoly of a single company, they'll never be cheap enough or otherwise viable for phone and tablet use.

    This is something i would actually consider for. Sure i would have to deal with constant refreshed screens and not play youtube so well, but i would actually take this phone once its fully out in its final version.

    The problems with smartphones is partially Blue light but the main problem is the refresh flicker/strobing/refresh of that blue light. Eink doesnt strobe/refresh as aggressively.
    Also guys? This isnt competing with cheap smartphones like the redmi. Its competing with the Lightphone and Punkt

    Yotaphone 3, the best of both worlds. Eink display like the phone featured and also an amoled display.

    I'd love to have a smartphone with regular screen on the front AND an e-ink screen on the back! e-ink would be fine for many of my needs, and the readability in bright sunlight is enough reason all on its own.

    Linus Vocabulary Tips... I know a lot of scientific equipment manufacturers that could benefit from these screens because they can't match the brightness of a basement dwelling priced smart phone with their current offerings and don't need high refresh rates or color... (YSI, HACH, TRIMBLE)

  • Zizi Mugen
    Zizi Mugen Month ago

    I wouldn’t use it for consuming media, but if it could properly and intuitively run common apps like maps, messaging, calling, weather, shopping online, etc., then I’d consider using it.
    I take it back, I’ve seen the whole thing now. This is one of those things that someone thought was a good idea simply because it was an idea.

    I find Ring doorbells really unpleasant and impersonal. Not to mention, it's pretty unethical that they disproportionately promote "news" stories about crime to create anxiety to encourage you to buy the product. Look it up. Not very happy that LTT is taking their money, but I'm not going to do anything about it

  • Christoffer Sahlgren

    I find it weird that he compares it with regular phones, the which this is ment to be as far away from as possible. If it has deezer or spotify l'd consider buying. The latency and so are supposed to be and that is the feature. This was a dumb review. As in he lost the point of the phone.

  • C R I P P L I N G D E P R E S S I O N

    It's actually a good device to cure addictions.
    What games could you really play with such a low framerate? What videos would you even watch to waste time? How could anything taken with this phone be instagram worthy? And don't even think about watching porn on there
    But yet it can do all those things if you really need to, plus the grayscale makes it better for your eyes and your brain.
    If it were just a bit cheaper I'd definitely buy one

    Reflected light is still the same light and no less "harmfull" then non-reflected light. E-ink is easier on the eyes because there is no flickering backlight.

    The price is really too high for such a phone and the backlight would be much better off being a warm yellow, make a proper OS skin optimized for greyscale viewing and you get a great phone a good number of people will take as business phone, I know I would.

    I closed this video after hearing 2:48 "What is it like to use it as a phone? It's pretty bad" and hearing him starting talking about the APPS. Apps, not the PHONE functionality. A phone is a device to take or make phone calls. The rest of it are just extra. If the question was "What is it like to use it as a SMARTPHONE" and then start talking about apps and shit, I would agree with this segway.

    I'll tell you why its expensive: patents. The e-ink screen is patented and e-ink inc have a sheltered monopoly for 20 years before anyone is permitted start working on making e-ink screens better and cheaper. e-ink screens are sold to a captive audience and the smaller the company, the harder the hit to their wallet.

    Who would this device use 2 gb ram? 1 gb ran is enough in my smarthphone playing games and with google apps but. This device is for basic use, a basic use does not need 2gb, is not needed for calls, camera and web browsing. Something around 512 mb of ram will be good enough.

    I think you are missing the point. The biggest feature of this phone is it's lack of apps. If you are outside a lot, that huge talk time will benefit you as well, since you won't be fighting the sun to see your screen.
    Sure, it's not for tweenie Twitter addicts and narcissistic selfie lovers, but they are not the target market.

    Whilst I don't imagine this phone winning any awards, it is an interesting experiment. There are color E-Ink displays available, with a spectrum of up to 4096 colours, so perhaps when this market is more developed we will see a competitor to LCD/LED. That won't be for a quite a while, however.

    *Blue light is a myth, I've been using LED phones for years without any problems, what fatigues your eyes is the OLED flickering, which gave birth to the idiotic orange backlight, yes flickering and on top of that being blue is double bad, but blue on its own is not that big of an issue, and not everyone reacts adversely to it. Shitty flickering OLED displays however -- are the reason why you cannot look at your shitty phone at night. Should have bought an LED phone retard.*
