I am a classical musician (violist) with 20 years of professional experience in orchestra and chamber music. For years, I have been using all kinds of large and very large tablets as part of my work as a musician.
I also have a degree in computer science, and I have always been interested in computer hardware. This article is therefore a summary of the hardware and practical side of using very large tablets.
I spent my school years in France, and this article must be riddled with spelling and grammar mistakes, for which I apologize. Feel free to send me any corrections!
What is the difference between the Meswao B3 and the B3 Pro?
The original Meswao MES-B3 was released in April 2024. In August 2025, Meswao quietly upgraded its largest tablet and added “Pro” to its name.
Unfortunately, the hardware was not upgraded except for the battery, which charges at 30 watts on the new Pro model instead of 15 watts on the old one.
This was a needed upgrade because the charging time dropped from six hours on the non-Pro model to three hours on the Pro version. But of course, it’s definitely not enough to merit the “Pro” label.
Verdict: It's the largest, but not the best.
Since modern reviews start with the conclusion, here are my final thoughts: The Meswao B3 Pro is not a very good tablet. Its display would be ideal for video streaming, but it has no Widevide L1 certification, which makes it suboptimal for HD streaming of copyrighted content (Netflix, Amazon Prime, HBO, etc.). It’s also super heavy!
Its outdated Helio G99 processor is fine for most users, but too slow for gaming or anything demanding. Meswao has no clear policy regarding Android upgrades or security updates, and they have been known for not pushing out security updates in the past.
On the other hand, the Meswao B3 Pro is unique and has no direct competitors. Its 15.6-inch display is much larger than what Apple (max. 13 inches) and Samsung (max. 14.6 inches) have to offer.
Despite its 16:9 aspect ratio, the area of the display is huge, representing 111% of a Letter-size sheet of paper. It is 10 % larger than the display area of the Samsung Galaxy Tab S11 Ultra and 28 % larger than of the iPad Pro 13-inch display.
If you want a high-quality, future-proof tablet with security support and Android upgrades, skip the Meswao MES-B3 Pro. But if you need the biggest tablet available and can compromise on processing power, video streaming quality, security updates, and more, then go for it!
Meswao MES-B3: Pros
- Biggest tablet on the market
- MicroSD card slot
- Stylus support (sold separately)
- Great price for its size!
- Supports Google Mobile Services
Cons
- Low-resolution display and low brightness
- Slow processor
- No Widevine L1 certification
- Stylus not included
- No information on security updates and software support duration
Streaming videos on the world's biggest tablet screen
With its enormous 15.6-inch display, it’s easy to see why the Meswao B3 Pro would be ideal for watching videos. To an extent, that’s true; movies are much larger and more comfortable to watch on this tablet than on any other large tablet.
Initially, I thought the 16:9 aspect ratio would look too wide or “elongated”, but that was before I tried movies in the Cinemascope (or DCI Scope) format of 2.39:1. As the picture below shows, there are still black bars on the top and bottom of the screen, and the movie uses only 1920 x 804 pixels (out of 1920 x 1080).

Having used the best tablets from Samsung (the Galaxy Tab Ultra series) and Apple (the 12.9- and 13-inch iPad Pros) for years, I expected the screen quality of the Meswao B3 Pro to be much worse. In reality, it’s OK for movies, but with the following caveats:
- The display is glossy and highly reflective. Any window or lamp causes glare.
Unfortunately, the Meswao 15.6-inch tablet has a glossy display that is prone to reflections, as can be seen in the picture. (By the way, this is a screenshot from the hilarious series “Extraordinary”, which is available on Hulu, Disney+, and Apple TV.) Photo: large-screens.com
- There are sometimes drops in streaming quality for a few seconds. Most users, including children, won’t notice, but if you want consistent, high-resolution videos, this tablet is definitely not for you.
- The Meswao B3 Pro does not have Widevine L1 certification. This means that copyrighted content from streaming platforms (including Netflix, HBO, Amazon Prime, …) may only be shown in SD and not in HD or 4K.

Meswao MES-B3 Pro: Performance
The Meswao MES-B3 “Pro” uses the same System-on-a-Chip (SoC) as the older, non-Pro model: the MediaTek Helio G99. This three-year-old entry-level processor is used in countless entry-level tablets, including models released in 2025.
Don’t expect to use performance-demanding apps, such as video editing or intensive gaming, on its huge screen. However, it is perfectly fine for normal use like web browsing, document editing, photo editing, and watching videos.

Is this really the word's biggest tablet?
Yes! The Meswao B3 Pro is definitely the largest tablet available in 2025.
In the past few years however, three foldable Windows tablets have been released, but they were extremely expensive and heavy:
- The Lenovo ThinkPad X1 Fold Gen 2 has a 16.3-inch display when unfolded. It was released in 2024 with an MSRP of $2,500, but it is no longer available from Lenovo and has no successor.
- The Asus Zenbook 17 Fold OLED has a slightly larger, 17.3-inch display. It was released in December 2022 with an MSRP of $3,500 in the US, and it is no longer available.
- The HP Spectre Foldable 17 has a 17-inch display when unfolded. It launched in October 2023 at a price of $5,000, but it has since been discontinued without a successor.
Apple has reportedly been working on a foldable iPad (or iMac) with a 20.3-inch display, but the release has been postponed to 2027 or 2028 – or even cancelled.1
Is that it? Do you call this a review?
I’m currently working on this review part-time while also taking care of three kids. Besides, there isn’t much information on the Meswao/Doogee B3 Pro online. I think it’s better than nothing and will continue working on it!
