Tablet Landscape Boot & Rotation Fix (TB-J716F) is a lightweight, systemless Magisk and KernelSU module explicitly engineered for the Lenovo Xiaoxin Pad Pro 2021. If you are running a TrebleDroid-based Generic System Image (GSI) and experiencing locked or incorrectly rotated screens, this module seamlessly restores your native landscape experience right from the boot sequence.
Native Orientation Restoration
Say goodbye to crooked boot animations and forced portrait lock screens on your tablet without compromising system stability.
GSI Compliant
Specifically targets TrebleDroid-based Generic System Images that often misidentify the tablet's native display rendering state.
Zero Scripts
Operates purely using standard system properties and RRO overlays, maintaining maximum system security without requiring risky SELinux patches.
Comprehensive Fix
Corrects the entire visual pipeline: aligning the boot animation, setting the default lock screen orientation, and fixing overall display bounds.
Under the Hood: Overlay Integration
Modern Android GSIs are built to be universal, but they often struggle to detect hardware-specific panel orientations on tablets like the Lenovo Xiaoxin Pad Pro 2021 (TB-J716F). As a result, TrebleDroid GSIs may render the interface in portrait mode by default, locking the boot animation and lock screen sideways.
Rather than relying on intrusive background scripts, this module safely injects Apache 2.0 licensed Runtime Resource Overlay (RRO) APKs directly from the TrebleDroid repository into the Android framework systemlessly. By combining these overlays with corrected build.prop properties, the OS is naturally instructed to treat the hardware display in a landscape matrix natively.
