    Why don’t all our phones have e-ink displays? It’s easy on the eyes, it’s more power efficient… what’s the catch? The Kingrow K1 phone with an e-paper display shows us the good and the bad…

    It should be noted that this phone can't be bought anywhere any more, the only ones I could find that one could watch out for (they're not being sold yet) are the Hisense A5 and A6.
    The A5 will allegedly only be 100$, so... damn.

    This actually looks very exciting! It's a shame that I wouldn't be able to play puzzle games or watch youtube videos on it but the improved readability and long standby times would quite possibly be worth it.
    Although I guess I'd then have to use the Android device simulator to use Tinder (if that even works). :P

    Wow. This review did not do the phone justice. This is not the phone for social media addicts. However it’s good for reading and communicating. Btw this phone is not back lit but front lit. Huge difference. It’s beyond me how someone who reviews tech can be oblivious to this.
    Personally I would categorize this phone for people who want get away from social media ie. dummy phone and still have features of smart phone. But your review was not geared towards the people it was intended for.

    I want this, but not for $350

    Hisense a6 is better than this.
    Despite it has two displays - AMOLED and e-ink it costs lower.

    what apps does the phone support? Gmail? Calendar? Does it have any messaging apps?

    Nice idea, but too expensive. Aside from Kindle and other e-reader apps, there isn't much point in it going all out on as a smart device. Better to scale back in as many ways as possible.

    isnt e-ink used in the gameboy advance?

    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.

    You know people give apple shit for "gimmicks" and same for google but everything about this phone screams gimmick its useless having an old nokia is more useful then this.

    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.

    Didn't one phone have a double sided screen? one side was eInk, the other side was a standard LCD screen.

    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.

    what if you wanted to use it as a phone and wanted to make phone calls with it and are not interested in all the other crap that comes with modern so called phones

    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.

    I miss my YotaPhone 2 sooo much, I loved the eink display, I used it almost exclusively, unless someone sent me a photo or something, then I would flip to the colour display

    It should have had different color temperatures for the backlight, cool for daytime viewing, and warm for evenings.

    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

  • x-illusion-x

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

      I have a Yotaphone 2, and it's fantastic. The software integration with the eInk display is great.

    BixbyConsequence 5 months ago

    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.

  • R.J. C.

    Not for me. A lame monochromatic screen won't cut it when you consider the % of time my phone is used for media consumption.

  • tinncan
    tinncan 5 months ago

    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 5 months 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 5 months ago

    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.

    $100 would've been a good price

  • 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.
