The Onyx Boox Go 10.3 (Gen II) Lumi is a good Android-toting Kindle Scribe alternative, but it disappoints in a couple of key areas

Now, I have to mention that there is a Gen II without a frontlight as well but, in my opinion, having the screen lit up just makes the epaper writing tablet that much more usable in any situation. With a frontlight, it also becomes a true Kindle Scribe alternative — again, thanks to its Android-based OS that gives the user access to the Google Play Store.</p><p>However, the aforementioned slow display is a disappointment as every time I woke up the Lumi to read or write, there would be a couple of screen refreshes (clearly marked as ‘Rendering’ when directly waking up to the native library application) before it settled down. Page turns, though, are fine but, again, Amazon’s 2025 Kindle Scribes are just that little bit faster at this as well. Long story short, screen performance doesn’t seem to have improved over the Gen I Go 10.3.</p><p>While I can live with the slower screen, I can’t fathom why Boox would retire the stylus that came with the original Go 10.3 as it was a lot better than the supplied InkSense Plus pen. The new stylus isn’t as smooth to write with, and is heavier, detracting from the all-important writing experience.</p><p>So as much as I’d love to say the Lumi is an improvement over its predecessor — and it is in a couple of ways — it just seems like Boox has taken two steps forward (with the frontlight and battery life) but one step back with the stylus.</p><figure class="van-image-figure inline-layout" data-bordeaux-image-check ><div class='image-full-width-wrapper'><div class='image-widthsetter' style="max-width:8064px;"><p class="vanilla-image-block" style="padding-top:56.25%;"><img id="cs5yGL39JLudtFpsSzxxDg" name="Boox Go 10 II Lumi_3" alt="Boox Go 10.3 (Gen II) Lumi and its InkSense Plus stylus lying on a laptop" src="https://cdn.mos.cms.futurecdn.net/cs5yGL39JLudtFpsSzxxDg.jpg" mos="" align="middle" fullscreen="" width="8064" height="4536" attribution="" endorsement="" class="inline"></p></div></div><figcaption itemprop="caption description" class=" inline-layout"><span class="credit" itemprop="copyrightHolder">(Image credit: Sharmishta Sarkar / TechRadar)</span></figcaption></figure><h2 class="article-body__section" id="section-boox-go-10-3-gen-ii-lumi-review-price-availability"><span>Boox Go 10.3 Gen II Lumi review: price & availability</span></h2><ul><li><strong>Announced March 2026</strong></li><li><strong>List price: $449.99 / £429.99 / AU$729</strong></li><li><strong>Available directly from the Boox Shop and third-party retailers</strong></li></ul><p>With the addition of the frontlight, the price of the Boox Go 10.3 (Gen II) Lumi is a lot higher than the launch price of the original Go 10.3 — you’re looking at shelling out $449.99 / £429.99 / AU$729 for the former, which is about $70 / £50 / AU$120 more than what the latter was when it was released in 2024.</p><p>That’s quite steep, although considering how expensive every bit of tech is getting thanks to RAM shortages, I’m not really surprised. It’s still competitively priced considering the 3rd-generation Amazon Kindle Scribe (2025 release with frontlight) retails for $499 / £449.99 / AU$849 for the 32GB flavor, while you get double the storage with the Lumi. Throw in the versatility of Android and it’s arguably better value (even compared to any of the reMarkables), but given its overall performance and user experience compared to the competition, I’d be hesitant to recommend it.</p><p>If the frontlight isn’t important, you can opt for the Gen II version without it, which will set you back $419.99 / £399.99 / AU$689. Prices for both Boox Gen II devices include the InkSense Plus stylus and a magnetic sleep case.</p><p><strong>• Value score: 4 / 5</strong></p><figure class="van-image-figure inline-layout" data-bordeaux-image-check ><div class='image-full-width-wrapper'><div class='image-widthsetter' style="max-width:4032px;"><p class="vanilla-image-block" style="padding-top:56.25%;"><img id="WWJwiFhfmTyPsfezZxS6ud" name="Boox Go 10 II Lumi_branding" alt="Branding on the rear of the Boox Go 10.3 (Gen II) Lumi" src="https://cdn.mos.cms.futurecdn.net/WWJwiFhfmTyPsfezZxS6ud.jpg" mos="" align="middle" fullscreen="" width="4032" height="2268" attribution="" endorsement="" class="inline"></p></div></div><figcaption itemprop="caption description" class=" inline-layout"><span class="credit" itemprop="copyrightHolder">(Image credit: Sharmishta Sarkar / TechRadar)</span></figcaption></figure><h2 class="article-body__section" id="section-boox-go-10-gen-ii-lumi-review-specs"><span>Boox Go 10.

I should note here that both Gen II Go 10.3 tablets are identical physically but, without LEDs on the unlit version, it’s about 14g (0.5oz) lighter.</p><p>While the slimness doesn’t make for fantastic ergonomics, the Lumi weighing only 364g is, in fact, lighter than the Gen 1 model that tipped the scales at 375g without screen lights. It is about 0.2mm thicker than the previous Go 10.3, but that’s neither here nor there.</p><p>It’s still a beautiful device and, despite the thinness, there are dual speakers on either side of the USB-C port on the bottom edge, as does a mic. The only button is for power/sleep on the top edge. There’s no microSD tray here, though, for additional storage. One larger bezel allows plenty of room for your hand, although holding such a slim device, no matter how light, isn’t necessarily ergonomic. If you add in the sleep case, however, it just becomes heavier.</p><figure role="gallery"><figure><img src="https://cdn.mos.cms.futurecdn.net/efKFXnAXRbc3d73vGeYEHh.jpg" alt="A Notebook cover on the Boox Go 10.3 (Gen II) Lumi" /><figcaption><small role="credit">Sharmishta Sarkar / TechRadar</small></figcaption></figure><figure><img src="https://cdn.mos.cms.futurecdn.net/VHQFxLR9zaUYudSncaFtXi.jpg" alt="A person holding the Boox Go 10.3 (Gen II) Lumi up to show the power button" /><figcaption><small role="credit">Sharmishta Sarkar / TechRadar</small></figcaption></figure><figure><img src="https://cdn.mos.cms.futurecdn.net/TUoR4meyNMewwbvJRcUCEe.jpg" alt="The USB-C port and speakers on the bottom edge of the Boox Go 10.3 (Gen II) Lumi" /><figcaption><small role="credit">Sharmishta Sarkar / TechRadar</small></figcaption></figure></figure><p>I should talk about the case here, really quick — it’s a faux suede cover that unfortunately comes with the removable flap that I utterly detest. The brown suede material starts to lose its luster within days of use, so I can’t attest to its longevity, but I can’t fathom why Boox has to make the magnetic flap removable. This has been the case with the last few Boox devices I’ve tested and I find it rather annoying — the magnet is quite strong and the flap tends to entirely come away when you unfold it to close the case or secure the stylus to the side of the tablet.</p><figure class="van-image-figure inline-layout" data-bordeaux-image-check ><div class='image-full-width-wrapper'><div class='image-widthsetter' style="max-width:4032px;"><p class="vanilla-image-block" style="padding-top:56.25%;"><img id="DSMtoCZwMuJ8uDgYAomafj" name="Boox case" alt="The Boox Go 10.3 (Gen II) Lumi and stylus in a brown magnetic sleep case" src="https://cdn.mos.cms.futurecdn.net/DSMtoCZwMuJ8uDgYAomafj.jpg" mos="" align="middle" fullscreen="" width="4032" height="2268" attribution="" endorsement="" class="inline"></p></div></div><figcaption itemprop="caption description" class=" inline-layout"><span class="credit" itemprop="copyrightHolder">(Image credit: Sharmishta Sarkar / TechRadar)</span></figcaption></figure><p>Speaking of which, the magnetic hold of the stylus is good but, as with nearly every such device, it’s not strong enough to keep the pen secure during travel, so you do need to depend on the case. </p><p>Boox has also changed the pen, now offering the InkSense Plus stylus that has a thicker tip that just isn’t as smooth as the previous stylus. It’s also slightly heavier than the older pen, which makes it feel clunky in the hand that, in my opinion, doesn’t lend itself well to controlled mark making on the screen. And as I’ve discussed elsewhere, <a href="https://www.techradar.com/tablets/ereaders/after-testing-over-a-dozen-digital-notebooks-ive-realized-that-the-stylus-is-the-real-mvp-in-the-e-ink-tablet-equation">the stylus can make or break the user experience for epaper tablets</a>. Sadly Boox is moving away from using EMR support on its screens (just like reMarkable), so you can’t use a third-party pen on the Lumi.</p><p>Boox hasn’t revealed what E Ink screen technology it’s using here, but the 10.3-inch display isn’t bad, with a 300ppi resolution. It’s not as yellow (warm) as I’ve seen on other Boox devices and the frontlight’s incremental adjustments for both brightness and temperature are excellent, adding wonderful contrast to the text or writing on the screen that makes the Lumi a far better reading tablet than its predecessor.</p><p><strong>• Design & display score: 4 / 5</strong></p><figure class="van-image-figure inline-layout" data-bordeaux-image-check ><div class='image-full-width-wrapper'><div class='image-widthsetter' style="max-width:8064px;"><p class="vanilla-image-block" style="padding-top:56.25%;"><img id="PP9Q3JoYaXGLDJtLnYn4eh" name="Boox Go 10 II Lumi_writing" alt="Handwritten notes on the Boox Go 10.3 (Gen II) Lumi" src="https://cdn.mos.cms.futurecdn.net/PP9Q3JoYaXGLDJtLnYn4eh.jpg" mos="" align="middle" fullscreen="" width="8064" height="4536" attribution="" endorsement="" class="inline"></p></div></div><figcaption itemprop="caption description" class=" inline-layout"><span class="credit" itemprop="copyrightHolder">(Image credit: Sharmishta Sarkar / TechRadar)</span></figcaption></figure><h2 class="article-body__section" id="section-boox-go-10-gen-ii-lumi-review-software"><span>Boox Go 10.

You still get unfettered access to the Google Play Store, so you can, in theory, use any Android app, but e-ink tablets weren’t meant for streaming content or playing games on.</p><p>That said, nearly every Boox device comes pre-loaded with native apps that are quite good in their own right and have been improved over time as well, making them more streamlined than before. That’s not to say the UX is easy — if you’ve never used a Boox device before, it will take time to wrap your head around it all as there are still little adjustments that are hidden in sub menus. </p><p>What’s different with the Go series compared to other Boox tablets is the home screen navigation — the main menu is arranged vertically on the left, with the Library being your default view. You can change the main menu items in Settings, though, either adding or removing applications. </p><p>Customizing the user experience has never been Boox’s problem, which means you can choose between several options for System Display or Gestures, and even tweak individual native apps as you see fit — even the NaviBall is optional to use and can be configured to trigger a plethora of functions.</p><figure class="van-image-figure inline-layout" data-bordeaux-image-check ><div class='image-full-width-wrapper'><div class='image-widthsetter' style="max-width:8064px;"><p class="vanilla-image-block" style="padding-top:56.25%;"><img id="DP4HDh9yFuGgZLqZQNx6bg" name="Boox Go 10 II Lumi_settings" alt="The settings pane on the Boox Go 10.3 (Gen II) Lumi" src="https://cdn.mos.cms.futurecdn.net/DP4HDh9yFuGgZLqZQNx6bg.jpg" mos="" align="middle" fullscreen="" width="8064" height="4536" attribution="" endorsement="" class="inline"></p></div></div><figcaption itemprop="caption description" class=" inline-layout"><span class="credit" itemprop="copyrightHolder">(Image credit: Sharmishta Sarkar / TechRadar)</span></figcaption></figure><p>The Control Center hasn’t changed much over the last couple of years, but I’m still not sure access to an AI assistant is necessary on an e-ink device, but perhaps some power users would appreciate it.</p><p>As always, you can sign into a fair few cloud services, including Google Drive and Dropbox, get full support for EverNote and OneNote, or download any other productivity application you might need, but keep in mind that not all third-party apps will be optimized for this device.</p><p>One of the things I really like about Boox’s premium note-taking tablets is OTG (on the go) support. This means I can plug in an external hard drive or portable SSD directly into the USB-C port to transfer files. In fact, it’s what I predominantly use even though BooxDrop is a handy app for cloud transfer. I don’t even bother signing into my Google Drive account on a Boox these days.</p><p>There really isn’t very much to complain about from a software standpoint — it’s the writing experience that takes a tumble here.</p><p><strong>• Software score: 4.5 / 5</strong></p><figure class="van-image-figure inline-layout" data-bordeaux-image-check ><div class='image-full-width-wrapper'><div class='image-widthsetter' style="max-width:8064px;"><p class="vanilla-image-block" style="padding-top:56.25%;"><img id="5YSB4ZgaFccFFGEiaVa5xg" name="Boox Go 10 II Lumi_library" alt="Book covers displayed on the Boox Go 10.3 (Gen II) Lumi" src="https://cdn.mos.cms.futurecdn.net/5YSB4ZgaFccFFGEiaVa5xg.jpg" mos="" align="middle" fullscreen="" width="8064" height="4536" attribution="" endorsement="" class="inline"></p></div></div><figcaption itemprop="caption description" class=" inline-layout"><span class="credit" itemprop="copyrightHolder">(Image credit: Sharmishta Sarkar / TechRadar)</span></figcaption></figure><h2 class="article-body__section" id="section-boox-go-10-gen-ii-lumi-review-user-experience"><span>Boox Go 10.

And that’s the case with the Go 10.3 Gen II Lumi — it does a lot right, like its reading experience is lovely, but its main functionality of writing is a little bit of a letdown.</p><h2 id="reading">Reading</h2><p>Like I said, reading on the Lumi is lovely — the frontlight makes the text stand out, adding contrast where previously, on the Gen 1, it was disappointing. Page turns are quick enough too with the screen quite responsive to taps and gestures.</p><p>And yet I feel it’s a little slow for an epaper tablet that was released in 2026. For example, every time I woke up the Lumi during my months-long testing, it took a while to ‘render’ an ebook from its native library app.</p><figure role="gallery"><figure><img src="https://cdn.mos.cms.futurecdn.net/qFCreourSrCzrfgVsJTjDn.jpg" alt="A book cover displayed on the Boox Go 10.3 (Gen II) Lumi" /><figcaption><small role="credit">Sharmishta Sarkar / TechRadar</small></figcaption></figure><figure><img src="https://cdn.mos.cms.futurecdn.net/ra8B4HhYZuN9rE74xNtP8i.jpg" alt="A page of an ebook displayed on the Boox Go 10.3 (Gen II) Lumi" /><figcaption><small role="credit">Sharmishta Sarkar / TechRadar</small></figcaption></figure><figure><img src="https://cdn.mos.cms.futurecdn.net/YkZrtURuCzapTUWwuLLZHj.jpg" alt="Text of an ebook displayed on the Boox Go 10.3 (Gen II) Lumi" /><figcaption><small role="credit">Sharmishta Sarkar / TechRadar</small></figcaption></figure></figure><p>It very much seemed like it was refreshing the app twice before finally rendering the page. On the other hand, the 3rd-generation Kindle Scribe released in 2025 takes a second or two to open but doesn’t flicker or ‘refresh’ the page — it’s a lot smoother on waking up. As are the <a href="https://www.techradar.com/tablets/ereaders/kobo-libra-colour-review">Kobo Libra Colour</a> and <a href="https://www.techradar.com/tablets/ereaders/amazon-kindle-paperwhite-2024-review">Kindle Paperwhite from 2024</a>.</p><p>Boox doesn’t reveal what E Ink screen tech its using, but other than its slight slowness on waking up, I can’t complain about the reading experience. All books and images rendered on screen have been sharp and clear, particularly with the frontlight on.</p><h2 id="writing">Writing</h2><p>The same kind of contrast with the frontlight on is available on the Notes app too where handwriting looks sharp and clear on screen. However, the physical act of writing on the Lumi isn’t as good as it has been on the Gen 1 because Boox decided to change the stylus. </p><p>The previous pen had a thinner nib that moved over the screen quite well. The new InkSense Plus stylus is heavier and the slightly thicker tip feels like it needs to be dragged to make a mark — it feels clunkier in comparison.</p><p>Boox has also stepped away from using EMR screens, which means you can’t swap that pen out for another. I tried using one of Boox’s own older pens (used to be supplied with the Note series) and it didn’t work. That’s a real shame as writing is the Lumi’s principal function and the experience of doing so is disappointing.</p><figure role="gallery"><figure><img src="https://cdn.mos.cms.futurecdn.net/yQWnkGipfhR2Rha2FjFrdf.jpg" alt="A person writing on the Boox Go 10.3 (Gen II) Lumi with the InkSense Plus stylus" /><figcaption><small role="credit">Sharmishta Sarkar / TechRadar</small></figcaption></figure><figure><img src="https://cdn.mos.cms.futurecdn.net/bebQmALTGjCsXvwufiLYGd.jpg" alt="The InkSense Plus stylus supplied with the Boox Go 10.3 (Gen II) Lumi" /><figcaption><small role="credit">Sharmishta Sarkar / TechRadar</small></figcaption></figure><figure><img src="https://cdn.mos.cms.futurecdn.net/LYJmaanxsbyBHAKDoPHd4d.jpg" alt="The InkSense Plus stylus supplied with the Boox Go 10.3 (Gen II) Lumi" /><figcaption><small role="credit">Sharmishta Sarkar / TechRadar</small></figcaption></figure></figure><p>The native Notes application, though, is full featured — in fact, for the average user it’s probably overkill — and would be ideal for students, teachers and researchers.</p><p><strong>• User experience score: 3.5 / 5</strong></p><h2 class="article-body__section" id="section-boox-go-10-gen-ii-lumi-review-performance"><span>Boox Go 10.

While it uses a better chipset (Qualcomm Snapdragon 690) compared to the original Go 10.3 (Snapdragon 680), it hasn't really made much of a dent in the speed with which the Lumi performs the tasks at hand. </p><p>That's not a complaint — it's an observation. However, Amazon's newest Kindle Scribes are just that much faster at things, like page turns are so quick they barely register that they've moved and the lag between pen input and the mark on screen is barely discernible. On both counts the Lumi is just that smidgeon slower that you can notice if you use it side by side with the 2025 Kindle Scribe (3rd generation).</p><p>The slow waking up of the screen is also something that has bothered me, and I've already mentioned how disappointing the writing experience is, but I'm also surprised at how much ghosting there still is on Boox devices, including the Lumi, something Amazon has managed to completely eliminate on its Kindles. You'll be able to notice the ghosting on nearly every single image I have in this review (including in the gallery below).</p><figure role="gallery"><figure><img src="https://cdn.mos.cms.futurecdn.net/cevgMn9Ar3jLh5oUpbpBqd.jpg" alt="A 'rendering' notification shown when the Boox Go 10.3 (Gen II) Lumi wakes up" /><figcaption><small role="credit">Sharmishta Sarkar / TechRadar</small></figcaption></figure><figure><img src="https://cdn.mos.cms.futurecdn.net/AuR4wiDUqJv6HkSoZ9P3bd.jpg" alt="Ghosting on the lit screen of the Boox Go 10.3 (Gen II) Lumi" /><figcaption><small role="credit">Sharmishta Sarkar / TechRadar</small></figcaption></figure></figure><p>Where the Lumi really shines (pardon the pun) is with battery life. It still uses the same 3,700mAh battery pack that was in the Gen 1 model and yet whatever software adjustments Boox has made has pushed battery life to weeks rather than days. It's the first Android digital notebook I've used to have such an impressive battery life, one that can match the Kindle Scribes, albeit dependent on use.</p><p>In my case, an hour of reading and 30 minutes of writing per day gave me 17 days of use with frontlight at medium brighness and a similar warmth setting, plus Wi-Fi on at all times (but not Bluetooth).
