YotaPhone evaluate: LCD on the entrance, E Ink on the again, distinctive throughout

YotaPhone review: LCD on the front, E Ink on the back, unique all over

We have lengthy contemplated the potential for an e-ink telephone. One that gives sufficient battery life to get us to the top of the day, or perhaps even the Finish of Days, just by being much less reliant on the facility-draining frivolity of an LCD or AMOLED panel. What we did not envision, although, was that the primary mass-produced try at such an concept would come from a Russian firm we might by no means heard of, or that it might take the notably uncommon type of the YotaPhone — a tool that does many issues in a different way, not least in having a curved E Ink panel on its rear aspect. As you are about to see, numerous these two-confronted concepts have potential, however a few of them want some work — a lot of labor, the truth is — earlier than they’re prepared for prime time.

After which there’s the worth tag, which can come as one thing of a shock in its personal proper given the YotaPhone’s mid-vary specs. It prices €499 in Europe, which equates to round $675 within the US (though the handset is not presently out there there). Meaning you possibly can truly purchase the Yota’s two halves individually for a extra reasonably priced sum; for instance, by getting a Nexus 5 and a Kindle. However, the power to purchase the 2-in-one YotaPhone is one thing we did not have a yr in the past, and one thing that is not provided by some other firm, and so it is value bearing that in thoughts as we proceed to put out its many flaws.

Yota Units



  • Nicely-designed and moveable regardless of the additional show
  • Helpful pre-put in apps show the E Ink panel is greater than a gimmick
  • Small software program fixes might have a huge impact, in the event that they occur


  • Poor battery life regardless of the E Ink consuming little or no energy
  • Does not help mainstream e-studying platforms
  • Higher Android handsets may be had for much less cash


Till we will run Kindle, Zinio, Spotify and different probably E Ink-pleasant apps on the rear show, the YotaPhone is not fairly value its excessive asking worth.

Hardware Design and construct high quality

YotaPhone review: LCD on the front, E Ink on the back, unique all over

You possibly can in all probability inform from the gallery above that this can be a fats cuboid of a telephone. It stands out for its blockiness and large bezels, which contribute to a most thickness of 9.9mm (zero.39 inch) and a weight of 146 grams. When it comes to quantity and weight, the YotaPhone is simply round 15 % greater than the HTC One mini, which has the identical four.three-inch display measurement, however it feels barely greater within the hand as a result of the thickness barely tapers on the edges.

The one exception to all this rectangular-ity is to be discovered on the prime-rear edge, which is thinner than the remainder of the telephone because of Yota Gadget’s most seen design flourish: a slight inward curve on the Gorilla Glass of its E Ink panel. This little element is delicate, however individuals do appear to note it — often across the similar time that they understand they’re taking a look at a twin-show telephone. Consequently, the YotaPhone’s look is a superb dialog-starter.

Now, chatting with strangers is good and all, nevertheless it’s not likely a cause to purchase a bit of know-how. Personally, we might be much more able to forgive the YotaPhone’s utilitarian look if its hardware lived as much as that promise, however it does not — at the very least not within the pattern we have been despatched for evaluation. The wraparound plastic band that holds the 2 panels collectively has the potential to be sturdy, particularly because it does not have to make any allowance for a microSD or swappable battery, however there are seen gaps between this band and the E Ink show. The difficulty is worst on the prime of the telephone, maybe as a knock-on impact from the curvature, to the purpose the place you possibly can truly see the SIM tray mechanism lurking behind the seam. Yota Units tells us that it has fastened this situation, however we will solely decide what we’ve got in entrance of us. We’ll replace this part once we obtain a completely ultimate handset, hopefully within the subsequent few days.

For a telephone that places such an enormous emphasis on studying, we might anticipate each shows to reside as much as the very best requirements, however they do not fairly meet that mark. The four.three-inch 720p LCD panel, made by Japan Show, is quite a bit higher than some we have seen and it definitely seems like present know-how, however its viewing angles and black ranges are a contact worse than what you’d get from a much bigger producer like Samsung, HTC or Apple.

Issues deteriorate barely once you get to the E Ink panel on the rear. Though the distinction and 640 x 360 decision are as much as snuff, the panel sometimes suffers from extreme ghosting from the earlier picture, such that it might look messy — though that is extra of a problem with wallpapers and different pictures, somewhat than clear textual content.

It is also value mentioning that there is no know-how right here that could not have been discovered on e-readers a few years in the past: no colour, no video-pleasant refresh charges and no glow-lighting. Neither is there contact sensitivity on this panel. This omission might have been inevitable from a producing perspective, however it might decide the whole destiny of this product, because it results in all types of software program limitations, which we’ll get to in a second.

As a method of coping with the shortage of contact, the parents of Yota have added a capacitive space beneath the panel, which may reply to swipes, faucets and holds — gestures that principally work OK, however which may typically by unresponsive. The identical gestures work on an equal contact-delicate space on the entrance face of the telephone, beneath the LCD, however we ultimately determined to activate the inventory Android on-display navigation buttons as an alternative, as a result of, once more, these swipe gestures weren’t all the time straightforward to get proper.

Digital camera

Do not be alarmed in the event you boot up the digital camera app solely to be confronted by a black display. It is simply your hand blocking the lens — a lens that’s positioned on the backside of the telephone as an alternative of the place you’d usually discover it, on the prime. This may increasingly have been an inevitable consequence of the E Ink panel, which is just too tall to go away area for the digital camera module above it, however the finish result’s awkward. The digital camera lens will get smeared extra actually because it is so near the place all of the swiping occurs, and the border across the lens makes it onerous to wash and not using a correct lens brush.

The digital camera’s place additionally means it’s a must to flip the telephone the wrong way up each time you need to take a photograph, and look forward to the gyroscope and OS to meet up with the brand new orientation earlier than you press the shutter button. Alternatively, it’s a must to grip the telephone by the sides, utilizing simply your fingertips, which does not all the time really feel fairly proper both.

If you will get previous this early awkwardness, nevertheless, you will shortly come to love the inventory Android digital camera app, which — like the remainder of YotaPhone’s working system — has been left largely unaltered. It is filled with speedy little shortcuts, like switching between the digital camera and the gallery by swiping to the left or proper; and tapping and holding anyplace on the display not solely to set focus and publicity but in addition to convey up a radial menu for fast entry to settings. The one onscreen digital camera buttons that you must fear about are the shutter launch and a mode button to shortly change between nonetheless images, video and panorama. All of it takes a little bit of getting used to, in the event you’re new to inventory Android, nevertheless it’s uncluttered and clever.

The YotaPhone’s thirteen-megapixel picture output is of respectable high quality for an off-the-shelf digital camera module, which is a well mannered means of claiming there’s little to report when it comes to both flaws or bonuses. JPEG compression is not too harsh, leaving round three.8MB of knowledge in a mean nonetheless, and the multi-publicity HDR mode often supplies pictures with minimal blur from handshake. Video high quality is equally competent, with quick and smart automated changes, and with mild sufficient compression to deal with element and movement. The one weak spot there’s with the audio, which sometimes pops and in addition has extreme noise discount that may make voices sound tinny. Lastly, the entrance-dealing with digital camera is satisfactory, however too low-res and too extremely compressed to make use of for something however video chat — output photographs are 1,280 x 720 and are typically lower than 200KB in measurement.

Software program

YotaPhone review: LCD on the front, E Ink on the back, unique all over

It is within the software program division that the YotaPhone comes alive. That is additionally the place it dies on its ft. The predicament is straightforward: There’s sufficient pre-put in software program on this telephone to exhibit that the second E Ink display has actual potential, however there’s not almost sufficient help for this show to make it helpful proper now.

Again when the YotaPhone was nonetheless within the prototype stage, we pressed its creators over the necessity to one way or the other help Kindle and different e-studying apps. We have been advised that this help would come, via a workaround that might permit the consumer to set off web page-turns utilizing swipe gestures, no matter whether or not Amazon’s Kindle app ever formally supported the YotaPhone’s E Ink panel. This concept hasn’t made it via to this construct, and that is an enormous limitation.

Because it stands, the one method to learn e-books on the YotaPhone’s E Ink display is via Yota’s pre-put in app, Bookmate, which appears to solely supply a handful of out-of-copyright gadgets in English. There is a subscription mannequin which may assist customers in Russia to entry a wider and newer vary of content material, however it’s not obtainable within the UK. In consequence, the telephone is at present ineffective for e-e-book studying — at the very least till somebody can discover a workaround to set off these web page-turns as Yota Units initially envisaged. (See the top of this text for a fast replace on the e-guide state of affairs.)

In any case, let’s take a step again and take a look at the way you truly get info onto the rear display.

The primary technique is by mirroring the LCD to the E Ink, by the use of a two-finger swipe downwards on the LCD aspect. That is mirroring of the dumbest type — you are successfully simply making a display seize after which displaying the JPEG on the rear panel. This may need a number of makes use of — if it’s essential to maintain a boarding move or some detailed information up on the display for some time — however these conditions are uncommon.

The second technique of sharing shows is far smarter. Apps which were constructed or custom-made for the YotaPhone have a button within the prime-proper nook of the display that triggers some perform on the rear panel — and as an alternative of only a static picture, this perform could be dynamic and interactive. Equally, the YotaPhone’s custom-made model of Android four.2 is ready to ship some notifications throughout routinely. The easiest way for instance that is by going by means of the three major pre-put in apps and features that will probably be of use to an English-talking viewers.

Whenever you get an e mail, textual content, climate alert or another notification, the YotaPhone provides the standard audio alert and shows a abstract of the notification on the rear panel. You then swipe to take away these notifications one after the other.

Relying in your chosen privateness settings, you possibly can determine how detailed a notification abstract is. It may simply be the variety of alerts of a sure sort which are awaiting your consideration, or it could embrace sender particulars and the primary line of content material. You may as well select to deal with notifications in a different way relying on who the sender is, by including sure contacts to an inventory of individuals whose notifications are handled as personal and stored off the everlasting rear show.

Calendar and Notes

You should think twice concerning the concern of privateness, as a result of individuals do discover what’s written on the again of your telephone — and since the telephone is so totally different, they typically can not help however stare. This is applicable to notifications, nevertheless it’s maybe much more necessary with the “Organizer” app, particularly when you’ve got colleague’s appointments proven in your Google calendar.

If you will get across the privateness challenge, both by retaining the telephone in your pocket or simply not caring about what individuals see on the again, you then may discover it extremely essential to have an all the time-on agenda displayed in your telephone. And this agenda is up-to-date, too: If somebody provides an appointment to your calendar, it’s going to present up on the E Ink panel mechanically after a brief delay.

The Organizer app is okay, and it gives primary management over which calendars to comply with, however it may possibly’t compete with calendar apps favored by energy customers. For instance, there’s little capacity to show to-do lists or notes alongside appointments — they will solely be proven individually, by the use of a Notes app, which ought to actually have been built-in into Organizer. That is the issue with Yota’s reliance on custom-made apps — they will simply by no means be as much as the extent of what is out there within the Google Play Retailer.


The YotaPhone comes with a pre-put in mapping app referred to as MapsWithMe, which provides nation-particular map downloads and appears to be comparatively dependable — no less than for the small a part of London geography that we examined it with. You possibly can set pins, and residential in in your place, after which hit the “Flip” button to ship the map to the all the time-on show. From there, you need to use swipe gestures to zoom in or out of the map. Sadly, the speed at which your place refreshes is method too sluggish for driving, nevertheless it’s useful sufficient at a strolling velocity.

Social networks and RSS

This app might be configured to ship tweets, Fb updates and RSS feeds to your rear show. Unusually, these notifications do not auto-replace; you need to swipe to unlock the display after which swipe once more or hit the quantity rocker to see the newest messages. One other limitation is that you would be able to’t present several types of messages on the similar time. That is no match for HTC’s BlinkFeed, for instance, which shows tweets alongside Fb updates and all the things else. Actually, it is exhausting to see how this might be referred to as a “hub” in any respect.

Efficiency and battery life

YotaPhone review: LCD on the front, E Ink on the back, unique all over

We encountered a couple of bugs with our evaluation unit. It crashed from time to time, for no apparent purpose, and needed to be restarted. Typically the lock display was unresponsive till the show was switched off after which on once more. However however, the telephone’s mobile features, WiFi, GPS and compass all appear to be dependable. The telephone’s bands aren’t suited to the US, however there’s wholesome help for 3G and LTE within the UK and Europe, together with the important thing 800MHz, 1,800MHz and a couple of,600MHz LTE bands. On Vodafone’s LTE community in London, we had no hassle getting past 10 Mbps down and up with a pair bars of reception, and the telephone was good at holding onto a weak LTE sign.

When it comes to the primary processor, we’re wanting on the Snapdragon S4 Professional of yesteryear. Yota Units initially stated that the YotaPhone would include a present-gen SoC, so we’re barely dissatisfied to not get a Snapdragon 600 and even 800 within the remaining construct. The S4 Professional’s efficiency is not dangerous by any stretch, with app load occasions and basic navigation fluidity that’s noticeably higher than Snapdragion four hundred telephones just like the HTC One mini, and never too far off Snapdragon 600 handsets just like the Galaxy S four and HTC One. In reality, when it comes to gaming efficiency as measured by 3D Mark, the YotaPhone was capable of marginally beat the newer HTC One Max, with 6987 factors. Then once more, a real flagship just like the Sony Xperia Z1 trounces the whole thing, whereas additionally revealing that different massive difficulty with the YotaPhone’s older processor: poor energy effectivity.

With the newest chips, we’re used to seeing greater than 9 hours in our normal battery rundown check, rising to 12 or extra hours on some flagship telephones. The YotaPhone barely survived seven hours in the identical check, on HSPA+ slightly than LTE, and its actual-world stamina was even worse. On a day with extraordinarily mild use, we might barely make it to 11PM with any battery left. Notching up the utilization barely, by throwing in music playback over headphones, Netflix and different actions, and we struggled to make it till 8PM. It is onerous to forgive this once we’re reviewing a handset that’s being bought on the idea of longer battery life.


YotaPhone review: LCD on the front, E Ink on the back, unique all over

That is an sad conclusion to succeed in, given all of the technical challenges that Yota Units has overcome prior to now couple of years. However it’s unavoidable: The YotaPhone is not but able to ship on its twin-display promise because of numerous points starting from poor construct high quality to brief battery life and, most significantly, an incapability to utilize its rear E Ink panel besides in a really restricted choice of pre-put in apps. With out help for our favourite e-guide and journal platforms, or for Spotify and different streaming apps, or transport updates and Google Now (which we’re advised is coming quickly), there simply is not a lot cause for us to flip the telephone over.

What’s wanted is an enormous push on the software program entrance. Not simply when it comes to stimulating third-get together app builders to take the YotaPhone significantly, but in addition by decreasing the telephone’s reliance on these builders within the first place. This may occur via higher mirroring of the LCD onto the E Ink aspect, fairly than the stagnant screengrab-mirroring we’ve got now, alongside some type of mapping from swipe gestures to plain navigation features (forwards, backwards, play, pause, et cetera).

This lack of help might probably be solved inside this era of the product, by way of some main software program updates, however we would not rush out to purchase the YotaPhone until and till that occurs. The opposite choice is to attend for an entire hardware revision, within the hope that it will deliver a full contact-delicate E Ink panel or another answer. Both approach, with all of the experience Yota Units has gained in placing this kind of show right into a telephone, there is a a lot better probability that such a hybrid handset will at some point achieve success.

Replace: Close to e-guide platform help on the E Ink show, Bookmate says it is engaged on offers with English-language publishers so as to deliver lots of, or probably “hundreds” of copyrighted titles by mid-2014. We’re additionally informed that the favored free Android app, FBReader, might be made to work on the YotaPhone’s rear display any day now, bringing the power to learn non-encrypted .epub and .mobi e-books, in addition to .doc and .rtf information. In the meantime, Yota Units says it is “discussing potential cooperation” with Amazon within the hope of getting help for Kindle books. We’ll proceed to cowl these developments as and once they occur.
