If your SHIELD Tablet was not affected by this morning’s recall, you can now enjoy the newly released Android 5.1.1 update. Inside, owners should see performance optimizations across the board, with NVIDIA forum members already praising the new speeds they are seeing.
The official changelog lists stability and performance improvements, plus system-wide optimizations and fixes, including audio.
Go grab that update and enjoy, if you were not affected by the recall. If you were, you still have to update the device, but then you should probably not use the device.
