Lenovo G02 Retro Handheld Review: A Familiar Chip With a Standout Screen

Introduction

A retro handheld with Lenovo branding recently appeared on AliExpress, and it immediately raised questions. Is this a genuine Lenovo product, or something else entirely? The answer turns out to be a regional licensing product, a practice Lenovo uses in the Chinese market. The result is a device that is essentially another clone of familiar retro handhelds, but with unique branding and a very interesting screen.

The Lenovo G02 is built around the Rockchip RK 3326 CPU, a chip that has been around for years and powers many budget retro handhelds. It comes with 1 GB of RAM and 4 GB of internal storage for the operating system, plus a micro SD card slot for games. The real highlight is the display: a 4.5 inch panel with a resolution of 1024x768. This is the same resolution as the TrimUI Brick, and as far as we can tell, no other handheld has used this particular screen. For a 4:3 display, 4.5 inches feels like a sweet spot.

The battery is rated at 4,000 mAh, which provides roughly 5 to 6 hours of mixed use. The device supports power delivery fast chargers, drawing about 6.5 watts while charging. At 251 grams, it is a bit on the heavier side for a retro handheld, largely because of its size. Connectivity includes Wi-Fi, though the specific version is not disclosed, and there is no Bluetooth or video out. The operating system is Linux, running a recent version of MuOS. A 3.5 mm headphone jack is included.

Pricing is where things get complicated. The Lenovo G02 is currently listed at about $75 on AliExpress. For a Rockchip RK 3326 handheld, that is notably high. This device is essentially another version of the R36S, which typically sells for between $20 and $30. Paying $75 for a very similar handheld feels steep, even with the unique screen and branding.

Design and Build

The packaging is cleaner than what we usually see with cheaper handhelds. The box features a nice product image and a list of specs on the back that feels reminiscent of a Lenovo box. One detail worth noting is the “1 TB” label, which some might misinterpret as internal storage. In reality, it simply means the device supports micro SD cards up to 1 TB in size.

Inside the box, you get the handheld itself, a USB-C charging cable, and a quick start guide that includes English instructions. There are a couple of color options, including a white model, but the black to red gradient version stands out. The overall look is unique and appealing.

The first impression upon holding the device is the large button in the center, which turns out to be an RGB button. It changes the RGB lighting around the analog stick and does nothing else. It is surprising that the biggest button on the device has a single function.

The Lenovo G02 is quite large for a vertical handheld. Compared to devices with 3.5 inch screens like the Anbernic RG35XX Plus and the Miyoo Mini Plus, it absolutely dwarfs them. It sits in the middle of larger vertical handhelds like the Anbernic RG406V with a 4 inch display, and the RG477V with a 4.7 inch display is slightly larger. Next to a Game Boy Color or the original Game Boy DMG, the size difference is clear.

The design language borrows heavily from the Anbernic RG40XXV. The face buttons, analog stick, and speaker placement are similar, and the back shows a strong resemblance in the trigger and shoulder buttons as well as the ribbing. It seems the manufacturer took cues from that device. One positive note is the texture of the plastic. It has a powdery matte finish that feels good in the hand and does not pick up smudges.

Controls and Comfort

The D-pad uses a traditional rubber membrane design. It has a circular base with posts that stick out at each end. It feels like a classic D-pad, though the pivot is not the best. In a game like Contra, the character stays put when pressing down and rocking left and right, which is typical of a rubber membrane D-pad. For fighting games like Street Fighter 3: Third Strike, the D-pad performs well, and special moves are easy to pull off.

The main complaint about the D-pad is the hard plastic. The little design ridges can start to hurt your fingers when rolling across them repeatedly. It is a minor issue, but worth knowing.

The face buttons feel good. They use a rubber membrane connection, are slightly rounded on the sides, and have a matte finish on top. They are accurate and do not bottom out. The analog stick is a pleasant surprise. It feels accurate and smooth with a wide range of motion, much better than the typical Nintendo Switch Joy-Con style sticks found on many R36S clones. The cap has a slightly rubbery, soft texture, which raises a concern about becoming sticky over time, but there are no immediate complaints.

On the front, there is the RGB light and an LED that turns red while charging. Select and start buttons are also present. The single mono speaker sits on the front as well. On the back, the shoulder and trigger buttons stick out slightly, making them easy to rest your fingers on. However, when laying the device down, pressing on it can inadvertently trigger these buttons. They are micro switches and not overly loud.

The right side has power and reset buttons, the left side has volume controls and the micro SD card slot, and the bottom has the headphone jack, charging port, and a port for peripherals. Overall, the device is comfortable to hold. There is plenty of space for fingers on the back, making it one of the more comfortable vertical handhelds available. The lack of a large ergonomic bump keeps it reminiscent of a Game Boy, which feels good.

Display and Audio

The display is the standout feature of the Lenovo G02. At 4.5 inches with a 4:3 aspect ratio, it handles systems like NES, Super Nintendo, and Nintendo 64 well, as those games fit nicely on the screen. However, nothing is truly integer scaled except for Nintendo DS. If you are looking for perfect pixel peeping, this is not the device for you. But at this high resolution, the scaling works out better than typical 480p displays.

The screen itself is decent. Colors pop well, and while it is an LCD panel rather than OLED, the overall size and relatively minimal bezels make it one of the more appealing 4:3 screens on a budget device. The higher resolution makes everything look sharp and crisp. At max brightness, it is good enough for outdoor play in the shade, though direct sunlight is a challenge.

Audio is less impressive. The volume is decent but does not get very loud. There are consistency issues that seem related to equalization within the software. Some games sound less accurate than others, with certain EQ bands not being properly represented. It is unclear whether this is a software problem or a hardware limitation, but the audio is not a strong point.

Software and Game Testing

The Lenovo G02 comes preloaded with the operating system and a 64 GB micro SD card full of games. There are around 1,200 Mega Drive games, a few Nintendo DS titles, about 1,000 Game Boy Advance games, 2,000 Game Boy Color games, and roughly 1,300 Super Nintendo games. The card includes a mix of Portuguese games from Brazil, Japanese games, and a “featured” best-of collection. Some full libraries, including Mario and Pokemon games, are present. It is a bit odd that a Lenovo-branded device ships with pirated ROMs, but that is what we are seeing here.

The software is MuOS version 4.7, an open-source free software that has been adapted for this device. This is common among R36S clones. Because of the unique 4.5 inch screen, other custom firmware options may not work out of the box, and it is uncertain whether developers will support this device.

The menu is very truncated. MuOS usually allows on-the-fly game settings adjustments, but most of that has been removed. You can adjust LED settings, change the theme from a handful of options, set sleep timing, adjust volume, and connect to Wi-Fi. System settings are limited to language and display brightness. It is a barebones setup designed for plug-and-play use.

Out of the box, Game Boy games play in black and white and are stretched to 4:3. Fixing this requires a few steps. Pressing select and X brings up the RetroArch menu. Under core options, you can change the Game Boy colorization to internal and select a palette like the classic DMG green. Then, under video scaling, change the aspect ratio to core provided. Finally, save a content directory override so the settings stick for all Game Boy games. There is a quirk where a core override already exists, so you also need to save content directory options to make the colorization persist.

Game Boy Advance games have the same 4:3 default, but changing the aspect ratio to core provided and saving the override works as well. Playing Game Boy Advance at the proper 3:2 aspect ratio looks great.

Performance is solid for older systems. Game Boy, Game Boy Color, Game Boy Advance, NES, Super Nintendo, and Sega Genesis all play perfectly. These 16-bit and home console systems are the best experience on this device, filling the 4:3 screen beautifully.

Higher-end systems are more hit and miss. PS1 plays at full speed at native resolution, and the full catalog is mostly playable, though some games are limited by the single analog stick. Nintendo 64 performance is problematic. Higher-end games like Cruising USA stutter, and the emulators apply hacks that cause graphical glitches. Legend of Zelda: Ocarina of Time is playable in terms of speed but has lighting issues, and GoldenEye has a white sky due to the hacks. Dreamcast is similar, with many games playable but requiring hacks and frame skipping. PSP is the last relatively playable system, with a good amount of the catalog working at native resolution, and the large screen makes 16:9 content a decent size.

The Alternative: GameM Battle XP G350

The Lenovo G02 is not a bad handheld, but the price is hard to justify. There are better options available for less money. The GameM Battle XP G350 is a personal favorite among R36S-style devices. It typically sells for around $40 to $50, and can often be found on sale for less.

The GameM Battle XP has a smaller 3.5 inch screen compared to the Lenovo’s 4.5 inches, which is the one area where the Lenovo has an advantage. Everything else, however, is a bit better with the Battle XP. It is believed to be made by Anbernic under a different sub-brand, and it shows. The controls are excellent, with a design very similar to Anbernic devices. The D-pad and face buttons feel great, and it has two analog sticks.

The GameM Battle XP also has a wide variety of community software support, including ArkOS and MuOS. For most people, the Battle XP G350 is the better value. It has better controls, wider software support, and a significantly lower price. Paying almost double for a larger screen is hard to justify, even when that screen is as good as the one on the Lenovo G02.

Buying Advice

If you are considering the Lenovo G02, there are a few things to keep in mind. First, the Lenovo branding is licensed, not an indication of Lenovo-level quality. This is a budget clone device, and the price of $75 is high for the Rockchip RK 3326 chip inside. Second, software support is uncertain. The unique screen means existing custom firmware will likely not work without modification, and it is unclear if the community will invest the effort. You may be stuck with the out-of-the-box software.

The screen is genuinely excellent, and it would be great to see this 4.5 inch display in future handhelds. The shell is sturdy, the controls are decent, and the matte plastic texture is pleasant. But for most buyers, the GameM Battle XP G350 offers a better overall experience at a lower price. It has superior controls, broader software support, and a proven track record. Unless the larger screen is a must-have, the Battle XP is the smarter choice.

Conclusion

The Lenovo G02 is an interesting curiosity. It brings a unique screen and recognizable branding to a familiar retro handheld formula. The display is the highlight, and the build quality is respectable. But the price is difficult to justify when comparable devices cost half as much, and the limited software support is a real concern.

For those who value the 4.5 inch screen above all else, the G02 is worth a look. For everyone else, the GameM Battle XP G350 delivers better controls, more software options, and a much friendlier price. The Lenovo G02 is not a bad device, but it is hard to recommend at its current price point.
