Xteink X4 Review: Should You Actually Buy One?

The Xteink X4 sells like a Kindle and does not behave like one. It has no store, no xteink Libby loans, no USB file copy, and no front light. The same week someone posted “The agony and the Xteink,” another owner wrote “this little guy singlehandedly got me out of my reading slump.” Same $69 device. The split is almost always whether the buyer knew those limits before the box arrived.

Why Do So Many Xteink X4 Buyers Get Blindsided?

The Xteink X4 became the first non-Kindle e-reader to crack Amazon’s top-10 e-reader sales chart (June 2026), briefly outselling the Kindle Colorsoft. Kindle buyers showed up expecting Kindle behavior. The surge kept building: Switch and Click’s “This $60 Device Killed My Doomscrolling” passed 276,000 views within four days of its July 13 upload, with the X4 at #11 on Amazon’s e-reader best-sellers and #2 on Hot New Releases (a filming-time snapshot; Amazon ranks move by the hour). That pulls in mainstream buyers, including some coming from an old Kindle Amazon just cut off from the store, who expect the X4 to work like a Kindle or Kobo. It doesn’t, and r/XTEINK sees the same confused day-one posts every week.

Answer these before you pay, not after the package arrives.

If any of those are a deal-breaker, do not order. If they are acceptable, run the checklist.

What Should You Check Before Buying an Xteink Reader?

These eight checks are for the Xteink X4. The same logic applies if you are ordering an X3 or X4 Pro now that the X4 itself is discontinued. Run through them so the device that arrives is the one you wanted.

Steps:

1. Confirm your reading sources are DRM-free. Own EPUBs, Gutenberg, Standard Ebooks, fan fiction. If you depend on Libby or a Kindle library, stop. Read Can you use Libby on Xteink?.
2. Accept that file transfer is WiFi, SD card, Calibre, or XT-Cloud. Never USB drag-and-drop. See how books actually get onto the X4.
3. If you want CrossPoint, buy from xteink.com or Amazon. Not Taobao, and not a risky AliExpress seller. Read Is My Xteink Locked? first.
4. Budget for a case and a slim PET screen protector up front. The thin panel cracks under pressure a phone shrugs off.
5. Plan for a separate clip-on light, kept off the screen. There is no backlight, and no firmware adds one. A white X4 can use CrossPoint’s Sunlight Fading Fix in bright sun. That does not light a dark room.
6. Have a known-good FAT32 microSD card ready. The bundled card is a common reason progress will not save and books will not load.
7. Plan to flash CrossPoint. Stock firmware reads books and is sparse. Nearly every review calling the X4 great was describing community firmware, not stock.
8. The day it arrives, run the two-minute lock test. Then work through the first-week setup checklist.

What Trips Up New Xteink X4 Buyers?

The day-one "wait, what?" list

None of these is a defect. They are Xteink X4 design choices that surprise anyone arriving from a Kindle.

No DRM, so no Libby, no Kindle library. The Xteink X4 has no DRM support, by design, and it is not coming in an update. Kindle store books, Libby and Overdrive loans (DRM-protected EPUBs), and most retailer purchases will not open unless you chose DRM-free at checkout. If Libby is the main reason you use an e-reader, the X4 is the wrong device. For your own library, start with DRM-free EPUBs, legally de-DRM only books you own, and test three to five titles before committing your whole collection.

What works: DRM-free EPUB and TXT files you own, Project Gutenberg, Standard Ebooks, fan fiction, personal documents, and Calibre libraries that are already DRM-free.

“I like knowing I own my books so I can move them from device to device.” (Ana, The Well-Appointed Desk)

USB does not transfer files. The USB-C port charges only. The Xteink X4 never mounts as a drive, so you cannot drag files in Finder or File Explorer. That surprises nearly every new owner. Three ways to load books onto the X4 work: copy EPUBs to /books on a microSD card; use the built-in WiFi web interface (a small local server you open in a browser); or use the official Calibre plugin for wireless sync. Xteink’s XT-Cloud sync service and Companion App (iOS/Android) are a further option once you have set up an account.

A microSD card warning. The bundled SD card, when one is included, can be unreliable, and it is a common culprit behind reading progress that will not save and books that will not load. If anything acts flaky, swap to a known-good card formatted as FAT32 (only cards larger than 32GB need exFAT). Reformatting and re-copying your /books folder resolves a surprising share of “my X4 is broken” reports.

The 4.3-inch screen is fragile. This is the costliest surprise on the Xteink X4, so it gets its own warning.

The community has documented successful panel replacements, so a cracked screen is not automatically a dead device. To protect the panel:

• Use only a slim PET/matte protector. A thick rigid-glass one can crack the panel it is meant to protect. See matte vs glass screen protectors.
• Clip lights should never clamp across the screen. Hook them to a case edge or aim a separate light from a distance.
• A case adds real protection on a device this thin. Edge knocks a phone case would absorb can crack a bare X4.
• Don’t leave it loose in a bag with keys. Abrasion damage is a regular thread type.
• Keep it out of hot sun. One long-term review reports faded streaks where the ink would not refresh after the reader rode in a bag under direct sun.

No front light. The Xteink X4 has no hardware backlight. You read in ambient light, or you clip a light to a case edge, never across the glass. If you read in bed with the lights off, that is a deal-breaker. CrossPoint’s Sunlight Fading Fix helps a white X4 in bright sun. It will not light a dark room.

Some units ship locked. “Locked” means USB firmware flashing is blocked, not that the Xteink X4 is broken. A locked unit still reads books on stock firmware. What it blocks is the easy browser flasher that installs CrossPoint. Liliputing and Good e-Reader reported the restriction in early May 2026, clustered on Taobao and AliExpress stock. You cannot tell from the box. If flashing is the point, buy from xteink.com or Amazon, keep returns easy, and run the two-minute USB test the day it arrives. CrossPoint’s unlocker is the fallback if the unit is locked.

Battery percentage can look erratic. A known open firmware issue makes the reported battery percentage jump around. It is cosmetic (actual runtime is still excellent), and the simple workaround is to hide the battery percentage in the reader’s display settings.

What’s the Xteink X4 Firmware Situation (and the Backlight Fix)?

The Xteink X4 ships with stock firmware that reads books and is sparse: limited fonts, no reading stats, basic EPUB rendering. Most owners flash CrossPoint within a week or two, the open-source community firmware (stable 1.5.0) with better fonts, reading stats, a cleaner layout engine, and a growing extension set. Nearly every review describing a great X4 was describing CrossPoint, not stock. Flashing an unlocked unit takes a few minutes in Chrome via a web flasher, no install needed. Locked units use the SD-card route instead. Forks and the full comparison live on the firmware comparison. When you are ready to flash, the CrossPoint install guide covers every path, including locked-device recovery.

No firmware adds a front light. If a white X4 washes out in direct sun, CrossPoint’s “Sunlight Fading Fix” (Display settings) improves outdoor legibility. That is the closest software answer for the missing xteink backlight, and it will not light a dark room.

What’s Better Than Expected on the X4?

The Xteink X4’s upside is real. At 77 grams the “always with you” compactness beats a bigger screen for how much you actually read. It is an adjustment coming from a Kindle Paperwhite, but almost every first-week post lands on “I worried it would feel too small, but the compactness is what makes it work.” The battery runs for weeks, and it sticks magnetically to MagSafe-compatible phone backs so it fills dead minutes on a commute.

Size, charging, and which pocket to pick are the job of the X3 vs X4 guide, not this page.

The X4 Is Gone: X4 Pro or S4 Instead?

The original Xteink X4 is discontinued as of August 12, 2026. New buyers pick the X3 (button-only, in stock, $69) or the X4 Pro (front light and touch, $99, stock comes and goes). Wait for the S4 only if Libby or Kindle apps are non-negotiable, and only if you will import from China. Specs, stock, and the buy-or-wait math live on the X4 Pro hub and the S4 hub. CrossPoint is not on the Pro yet, so flashers who want community firmware today want the X3.

Xteink X4 vs Just Reading on Your Phone: Which Wins?

The question every skeptic asks first

On specs, your phone wins. The X4’s own 307-point Hacker News thread (187 comments, June 2026) keeps circling one objection: your phone already has a Kindle app, a bigger screen, and a backlight, so why carry a second, deliberately worse device? The skeptics are right that the X4 wins none of those categories. The case for the X4 is what happens in the ten seconds before you’d otherwise pick up a book at all:

“Sure I could read the same book on my phone, but it takes multiple steps to open the e-reader app on my phone. On top of that, there are half a dozen other things I could open on my way to opening up my e-reader app. With X4, I press the button on the side and I’m reading.” (mmstghjx, Hacker News)

One reply on the same thread compressed the whole tradeoff into a single line:

“A single-function book is your window to the world. A phone is the world’s window to you.” (nomand, Hacker News)

If you already read comfortably on your phone, the X4 adds nothing and the $69 is better spent elsewhere.

The Verdict: Should You Still Buy an Xteink X4?

If you already own an X4: yes, it is a good pocketable button reader for DRM-free EPUBs, and everything above still applies. If you are shopping today, the X4 itself is not an option. Xteink confirmed it discontinued it on August 12, 2026 (see the intro above for the source), and the buying decision now is between the X3 and the X4 Pro.

• Existing X4 owners: keep using it. It is a pocketable reader that’s always on you with the CrossPoint ecosystem behind it, and the anti-doomscroll, “first book in years” effect is real.
• New buyers who want the X4’s simplicity: get the X3, the same DRM-free, button-only formula, smaller, and confirmed in stock.
• New buyers who want a front light or touchscreen: check X4 Pro stock. It launched July 21 at $99 but has sold out in waves, and CrossPoint is not ported to it yet, so flashers may want to wait for the port. Details are on the X4 Pro hub.
• Wait for the S4 if Libby or keeping your Kindle library is non-negotiable, and only if you will import from China. Status: everything we know about the S4.

If you are buying a used X4, check whether it is locked before you pay, then keep the first-week setup checklist open when it arrives. Comparing live models is the job of X4 vs S4 vs X4 Pro.

Quick Answers Before You Buy

Can I read Libby or Overdrive books on the X4?

No. Libby and Overdrive lend DRM-protected EPUBs, and the X4 (on stock or CrossPoint) cannot open DRM-protected files; there is no Libby app on the device. You can read titles you own outright or public-domain books; plan your library workflow around DRM-free sources. The full answer, including Libby's DRM-free Open EPUB exception, is on Can you use Libby on Xteink? If Libby is essential, the S4 is the Xteink that might help, and it is still China-only.

Does the X4 have a backlight?

No. There is no front light, so you need ambient light: a lamp, daylight, or a clip-on light kept off the screen. CrossPoint's "Sunlight Fading Fix" helps a white X4 in bright sun, but nothing lights a dark room. If you read in bed with the lights off, that is a dealbreaker.

Can I just plug it in over USB and copy books across?

No. The USB-C port only charges; the device never mounts as a drive. Books go on via the built-in WiFi web interface, a microSD card's /books folder, the Calibre plugin, or Xteink's XT-Cloud. It's not hard once you know USB drag-and-drop isn't an option.

Why do people return the X4?

Almost always the DRM wall. Buyers expect their Kindle library or Libby loans to "just open," and they can't; only DRM-free EPUB and TXT files work. Knowing that before ordering is the single biggest predictor of whether you'll keep it.
