Comfort and grip matter when you hold a device for hours. This e-reader features large bezels around the screen. These wide edges give your fingers plenty of space to hold without accidentally touching the display. Your hands stay comfortable whether you read for 20 minutes or several hours straight.
The screen itself delivers a paper-like feel that mimics real book pages. You get a high-resolution display that shows text clearly and sharply. Reading doesn’t strain your eyes the way backlit screens do on phones or tablets.
You have two ways to turn pages on this device. The touch screen lets you swipe forward or backward instantly. Physical page-turn buttons sit on the sides for users who prefer tactile controls. This dual-input system gives you flexibility, though some people accidentally press buttons during casual handling.
The adjustable front light is another portability win. You can switch between warm and cool tones depending on your environment or time of day. Reading at night? Use the warm setting. Reading outdoors? Switch to cool light for better contrast. The best part is that this front light barely drains your battery, so you won’t need to charge constantly.
Compared to the lighter Xteink X3 at 58g, the X4 Plus feels slightly bulkier. However, the extra weight brings features like the front light and touch screen. Most users find this trade-off worthwhile for added functionality.
The unlocked firmware means you can customize how your e-reader works. You’re not locked into one company’s software limitations. Your reading device adapts to your needs, not the other way around.

Display and Reading Experience
The display on the Xteink X4 Plus makes reading feel natural and comfortable. The paper-like screen mimics the texture of actual book pages, so your eyes don’t strain during long reading sessions. This matters because e-ink technology reduces glare compared to tablets and phones.
The adjustable front light gives you control over your reading environment. You can shift between warm and cool tones depending on the time of day. Warm light works better before bed, while cool light suits daytime reading. The system drains very little battery power, so you won’t watch your charge disappear after a few hours of use.
Touch input combines with physical page-turn buttons for flexibility. Some readers prefer tapping the screen, while others like the tactile feedback from buttons. This dual approach means you can choose what feels right in the moment. The physical buttons sit on the sides, which some users note can trigger accidental presses if you’re not careful with your grip.
The large bezels around the screen serve a real purpose. They give your fingers space to hold the device without accidentally touching the display. This design choice prioritizes comfort during extended reading sessions. Your hands won’t cramp or slip as easily as they would on a device with minimal bezels.
High resolution ensures text appears sharp and crisp at all sizes. Whether you’re reading novels or documents with small fonts, clarity remains consistent. The display handles different font sizes well, so you can adjust text to match your vision needs.
The 5.95mm thin profile means the screen sits flush with the device body. There’s no awkward gap or bulky frame around the edges. Combined with the 72g weight, this thinness makes the X4 Plus genuinely pocket friendly.
Overall, the display delivers a reading experience that feels close to paper. The adjustable lighting, responsive controls, and comfortable bezels work together to create a device you’ll want to use every day. Whether you’re commuting or relaxing at home, this screen keeps your focus on the story.
Controls and User Interface
The Xteink X4 Plus gives you two input methods to navigate your reading. You can use the touch screen for quick page turns, or rely on the physical page-turn buttons positioned on either side. This dual approach means you choose what feels natural in the moment.
Touch controls work smoothly across the display. Tapping and swiping respond quickly without lag. The screen registers your input reliably, so you stay focused on your book instead of fighting the interface.
The physical buttons offer a tactile alternative. Many readers prefer buttons because they prevent accidental screen touches. You can turn pages without looking at the device, which helps during bedtime reading or when your hands are cold.
Large bezels frame the screen and serve a practical purpose. They give your fingers safe space to grip without triggering unwanted taps. This design choice prioritizes comfort over a frameless look, and it works well for extended reading sessions.
The front light controls sit within easy reach. You can adjust brightness and shift between warm and cool tones without opening menus. This simplicity matters when you want to customize your reading environment quickly.
Menu navigation feels straightforward. The interface doesn’t overwhelm you with options or confusing layouts. Finding settings, adjusting fonts, or accessing your library happens smoothly.
The unlocked firmware opens more possibilities. You can modify how the device behaves and install custom software if you want deeper customization. This flexibility appeals to users who like tinkering with their gadgets.
One consideration: the physical buttons sit in positions where your hands naturally rest. Some users report occasional accidental presses when holding the device. Being aware of button placement helps you avoid this issue.
Overall, the control scheme balances simplicity with flexibility. Touch and buttons work together instead of competing. You get responsive feedback from both input methods, making page navigation feel intuitive and comfortable during long reading sessions.

One thing to watch: the physical buttons sit where your hands naturally rest while holding the device. This positioning occasionally causes accidental page turns during extended reading sessions. Most users adapt quickly, but it’s worth knowing before purchase.
The software experience feels straightforward without unnecessary complexity. Menu navigation doesn’t require multiple taps to reach common functions. The interface prioritizes reading over flashy features, which keeps your focus on the book itself.
