Lenovo TBX704F (Tab 4 10) Android Update 2021: The Complete Breakdown

Published: March 15, 2021 | Updated: December 2021

If you own a Lenovo TBX704F, you are likely holding the Wi-Fi-only version of the Lenovo Tab 4 10 (model number TB-X704F). Released in 2017 with Android 7.1.1 Nougat, many users have been anxiously waiting—and often confused—about the device’s software future. This article covers everything you need to know about the Lenovo TBX704F Android update in 2021, including official releases, security patches, custom ROM alternatives, and what to expect going forward.

4. Why Didn't the TBX704F Get Android 9+ in 2021?

Lenovo cited two primary reasons:

Hardware limitations: The Snapdragon 425/427 chipset and only 2GB RAM struggle with Android 9’s Project Treble requirements and newer ART runtime.
Business strategy: Lenovo shifted focus to the Tab M8/M10 series (Android 9 and 10). Supporting older budget tablets conflicted with their GSI (Generic System Image) roadmap.

User frustration was understandable, especially since some Snapdragon 425 phones did receive Android 9 (Go Edition). However, Lenovo stopped custom ROM development for the TBX704F internally in 2019.

Here’s a step-by-step guide for updating the Lenovo TB-X704F (also known as the Lenovo Tab 4 10 or Tab 4 10 Plus, depending on the exact sub-model) to its 2021 Android update.

Important note before you start:
The TB-X704F is an older tablet (released 2017–2018). Its last major official Android update was Android 8.1 Oreo (some regions received security patches into 2020/2021). There is no official Android 9, 10, or 11 from Lenovo for this model.
If you’re looking for a “2021 update,” it would be a security patch or a minor bug-fix release, not a new Android version.

8. Conclusion: Is Your Lenovo TB-X704F Still Usable After the 2021 Updates?

Absolutely. Despite the lack of newer Android versions, the Android 9 Pie update in 2021 breathed new life into the TB-X704F. With the final security patches from late 2021, the tablet remains secure enough for daily tasks like:

Streaming video (Netflix, YouTube, Disney+).
Reading ebooks and PDFs.
Light gaming (PUBG Mobile on low settings, Among Us, etc.).

However, by the end of 2021, users should treat this as a legacy device. App developers will begin dropping Android 9 support around 2023–2024, but for now, the Lenovo TB-X704F Android update in 2021 delivered exactly what owners needed: stability, security, and a modern interface.

Final Tip: Always keep automatic updates enabled for Google Play Services and core apps. Even without OS upgrades, Google Play System Updates (Project Mainline) will continue to push critical component updates for another year or two.
